Ladies and gentlemen, good afternoon, and thank you for joining Airbnb's Earnings Conference Call for the Second Quarter of 2024. As a reminder, this conference call is being recorded and will be available for replay from the Investor Relations section of Airbnb's website following this call. I will now hand the call over to Angela Yang, Director of Investor Relations. Please go ahead.

Good afternoon, and welcome to Airbnb's first quarter of 2024 earnings call. Thank you for joining us today. On the call today, we have Airbnb’s Co-Founder and CEO, Brian Chesky and our Chief Financial Officer, Ellie Mertz. Earlier today, we issued a shareholder letter with our financial results and commentary for our second quarter of 2024. These items were also posted on the Investor Relations section of Airbnb's website. During the call, we'll make brief opening remarks and then spend the remainder of time on Q&A. Before I turn it over to Brian, I would like to remind everyone that we will be making forward-looking statements on this call that involve a number of risks and uncertainties. Actual results may differ materially from those expressed or implied in the forward-looking statements due to a variety of factors. These factors are described under forward-looking statements in our shareholder letter and in our most recent filings with the Securities and Exchange Commission. We urge you to consider these factors and remind you that we undertake no obligation to update the information contained on this call to reflect subsequent events or circumstances. You should be aware that these statements should be considered estimates only and are not a guarantee of future performance. Also, during this call, we will discuss some non-GAAP financial measures. We provide a reconciliation to the most directly comparable GAAP financial measures in the shareholder letter posted to our Investor Relations website. These non-GAAP measures are not intended to be a substitute for our GAAP results. With that, I will pass the call to Brian.

All right. Good afternoon, everyone, and thanks for joining. Q2 marked another strong quarter for Airbnb. We had 125 million nights and experiences booked. Revenue increased 11% year-over-year to $2.75 billion. Net income was $555 million representing a net income margin of 20% and we generated $1 billion of free cash flow. Our total trailing 12 month free cash flow was $4.3 billion, our highest ever, and our strong cash flow allowed us to repurchase $749 million of our shares in the quarter. And as of the end of Q2, we had $5.25 billion remaining on our share repurchase authorization program. Now during Q2, we continue to make progress on our three strategic priorities, which again are making hosting mainstream, perfecting our core service and expanding beyond the core. So I’ll share a few highlights on each. First, we are making hosting mainstream. Last year, we shared a commitment to make hosting just as popular as travelling in Airbnb. We've been focused on raising awareness around the benefits of hosting and providing better tools for hosts. In Q2, we surpassed 8 million active listings driven by continued growth across all regions and market types. We're not just growing supply and we're also committed to ensuring that it's high quality supply. Since launching our updated host quality system last April, we’ve removed over 200,000 listings that failed to meet our guests expectations. And we'll continue to raise the overall quality of listings on Airbnb so we can consistently deliver high quality stays. Second, we're perfecting our core service. We remain focused on making Airbnb more reliable, affordable and a overall better service for hosting guests. We’ve rolled out hundreds of new features and upgrades over the past two years to do this. This includes launching major reliability initiatives like guest favorites…

[Operator Instructions] And your first question comes from the line of Ron Josey with Citi. You're line is open.

Great. Thanks for taking the question. I have two please. Brian, just with your last comments on slowing lead times and what not in North America. Can you tell us a little bit more about that when you saw those trends sort of first hit. And then, how it offsets the strength from the Olympics and UEFA and everything else? And that's question one. And maybe a bigger question when we think about expanding beyond the core and perfecting the core service. Post summer release, posts winter release we've seen a lot of key improvements across Airbnb with Guest Favorites, with Icons and the list goes on and on, , how does - when we think about the coming winter release and throughout ‘25 and everything else, how are these newer services helping to influence call it the Airbnb of tomorrow? Thank you.

Yes, why don’t Ellie you take the first one about slowing lead times and when we started seeing these trends and I'll take the second one.

Yeah. Yeah, absolutely. So let me double click a little bit in terms of the trends for lead times since the beginning of the year. In both Q1 and Q2, what we saw with that lead times were basically equivalent with what we had seen in 2023. So there wasn't really any timing shift behavior in terms of when guests were booking. What we’ve seen more recently and in particular in July is a shrinking of the lead times and in particular what we've seen is that there continues to be very strong growth of the shorter lead times. So anything from same day to next week to a couple of weeks from now. But what we're not seeing the same level of strength is in those longer lead times. So two months from now, what you’re booking for Thanksgiving what you’re booking for Christmas, and so it's that I would say softness in terms of longer lead times as a big factor in terms of the outlook that we've provided. What I would say additionally is that, over the last couple of years as we emerge from covid, there were several periods where we saw some volatility in terms of overall lead times and in particular some hesitancy for consumers to book those longer lead time trips. I suspect that's what we're seeing right now and the - I would say the silver lining with regard to the trends that we see right now, it's not that consumers are not necessarily going to book that trip for Thanksgiving or Christmas. It just appears that they have not booked it yet. So we're closely following all of the trends on lead times, but it is a factor that informs the outlook that we provided for Q3.

And your next question comes from the line of Doug Anmuth with JPMorgan. Your line is open.

Sorry, sorry.

My apology.

Sorry, there was a second part of the question. So, Ron, to answer your question about expanding beyond the core business. Where we are is we spent 16 years building a business that's approaching $80 billion in gross booking value that's basically one category, which we call Airbnb which is short term accommodation. It's been pretty amazing how far this single product has gone. And we haven't really charged other than like essentially travel insurance, we haven't really ever really expanded beyond our core business and we do have long-term stays which are [17%] (ph) of nights. We haven't done very much. We began before the pandemic preparing to expand Airbnb. And then when the pandemic hit, we cut back a lot of our resources. We got focused, went back to our roots and really focused on rebuilding our platform, becoming lean, becoming a functional organization and we now have essentially the same amount of employees as before the pandemic and double the revenue and that explains why we have 41% free cash flow margin, one of the most profitable companies in tech. We're now beginning to prepare the next chapter of Airbnb. And I want Airbnb to be one of the most important companies of our generation and to do that, we're going to do more than one thing. We're going to do multiple new things. We're going to have to have multiple new products and multiple new services. This fall, this October, we're going to be launching a new host service which is really important. It's essentially a co-hosting marketplace. So, there are people that have homes but they don't have time. There are other people in the world that have time but they don’t have a home. And so, there's a Venn diagram of people today who…

And your next question comes from the line of Doug Anmuth with JPMorgan. Your line is open.

Thanks for taking the questions. Ellie, just to follow up on I know you talked about the shorter booking window. Are you seeing any change in activity around pricing or class of property? And is there anything to call out across cohorts or income levels? And then, Brian just circling back on expanding beyond the core, are there any expansion markets in particular that you would call out where you're seeing particularly strong traction? Thanks.

Yes. So, why don't Ellie, you take the first. I’ll take the second.

Yeah. so Let's talk a little bit generally about ADR, so question was like what are people are actually purchasing on the platform. I would say, generally, so far this year what you've seen is a little bit of ADR appreciation globally. In particular, obviously, but more recently in North America. And what we see there is a big driver of the ADR appreciation is big shifts, which you can assume is what it sounds like people choosing more expensive or larger properties. And I think part of the read through from that can be oh, people are choosing more expensive listings. Therefore, you are seeing stronger demand from higher economic demographics. I think that is one read through. I think another read through is that, if you think about the value proposition of Airbnb, it's that we offer these larger properties and on a per guest basis, they can be quite affordable and frankly more affordable than a hotel. So I think part of that ADR mix shift appreciation that you see is frankly people gravitating to where we actually have some great value, which is the larger Airbnb that that do provide value on a guest level.

And to answer your question about expansion markets, maybe a framework I can give to think about how we want accelerate growth, listen, we want to be growing a lot fast than we are. We want to be growing in healthy double-digit growth - double-digit growth and I think we can. And the way we're thinking about accelerating growth is through short-term, medium- term and long-term. Short-term is really optimizing our core business. It's really around affordability, about having high quality stays and just conversion rate increases. Long term is really about new products and services. So, the question you asked about international is interesting because it's kind of like a medium term horizon, like one to three years. And to frame this, Airbnb is in 220 countries and regions. We're one of the most global companies in the world on the Internet, 220 countries and regions. We operate nearly in every country in the world. But there's only really five markets where we're penetrating. And those markers are the US, UK, France, Canada and Australia. And you'd think like, well, if there was one company in the world that would truly be like have a lot of international penetration it’d be a global travel network, right? A website where you want to travel, use one platform to travel around the world. So there's a number of countries. Just to give you a couple of examples of our some big expansion markets, Germany and Brazil we've seen a lot of progress. Those are huge travel markets and the biggest travel markets in the world. And we're continuing to go bigger. In Europe, Italy and Spain, we have low penetration compared to France and UK and these are major destinations. Then in Latin America, we've had a lot of progress in…

And your next question comes from the line of Richard Clarke with Bernstein. Your line is open.

I just want to unpick the Q3 revenue guidance a little bit more. I guess the - if I look from the balance sheet your funds held on behalf of customers, to me it looks like it's up about 13% year-on-year. So it looks like you're carrying more bookings into the quarter and then you're talking about shorter lead times. So does that mean more bookings in the quarter for the quarter. So just trying to square that with why revenue is slowing down in your guidance?

Yeah, thanks Richard. So, obviously, that that energy is balanced on - on the balance sheet gives you some indication of the backlog. I would not take those balance sheet items as a one for one read through in terms of the revenue that will be recognized over the course of the quarter. A couple of deviations in terms of why they might not match. One is obviously a good portion of the bookings that we will recognize in a particular quarter are still to be booked within the quarter? That's one aspect. The second is the balance sheet items will reflect the timing of the payments, the - whether it’s pay less upfront or the entirety of the payment and so they're just not a one for one guide. All they do, they do obviously give a time stamped point in time view of the backlog that we have.

And your next question comes from the line of Eric Sheridan with Goldman. Your line is open.

Thanks so much for taking the question. Maybe I can ask a two-parter coming back to the booking window. When you've – what you’ve seen over the last couple of years in terms of the booking window evolving from where it was pre-pandemic to where it is post-pandemic how much differ just that booking window look today versus maybe 2019 as opposed to today versus one in two years ago. And when you think about what that shift looks like, how much of that do you think in terms of a shortening booking window are elements of demand-driven Dynamics where the consumer might want to spend less money and be more discerning. Or just elements of normalization that are working in the way back into global travel? Thank you.

Thanks, Eric. So, let's talk about lead times over time. If we look at where we were say in Q2 of 2019, the average lead time across the platform was within one or two days of what it was in Q2 in ‘24? So from the kind of pre-covid to last quarter, there hasn't been some material shifts. What you did see through the path of covid was initially, we saw a massive reduction in lead time because people had no confidence in terms of their ability to book far out. That, that reversed in say the 20 to 2022 to ‘23 time period where people are so eager to travel that they were booking way in advance of their kind of normalized patterns to make sure that they had the trip on the book. They got the most attractive listing at the best price by booking early. And I think fast forward to ‘24 you're seeing up and up through Q2 a very much return to normal. So hopefully that's helpful in terms of the overall four-year arc. In terms of having some color commentary in terms of what we're seeing today, just to reiterate some of the color I provided at the beginning of the call. The last minute bookings are incredibly strong. So they are, I would say much higher in growth rates than what we are guiding to in terms of the average. There seems to be a lot of desire in terms of making sure you get your summer travel in at very elevated rates. But it's being offset by that portion of bookings which is for us about half of the overall bookings, which are a month or longer. And I think it's a minor - it's a minor softness, but it does have impact in terms of our backlog just given the concentration of bookings that happen more than a month in advance. There's just a modest amount of softness that is bringing the average lead times down. And I think what we’ve seen in the past is from time-to-time whether it be a new COVID variant, whether it be a macro headline, whether it be like last year the outbreak of war in Israel. People from time to time have moments where they are not booking in the same timeframe that they did in prior periods, and that's what we're tracking closely right now.

[Operator Instructions] Your next question comes from the line of Brian Nowak with Morgan Stanley. Your line is open.

Thanks for taking my questions. Maybe I'll squeeze in two. Let me ask one on the marketing expense comments for you Ellie. You mentioned in the guide marking expense has been real faster than revenue in the third quarter. I guess, the question is how do we think about performance versus brand expend and I think you sort of learned about your marketing spend over the years sort of gives you confidence this could resonate even faster room than growth this time around. And then one for Brian and sort of Gen AI and philosophical strategy. There's a lot of talks that are about top of funnel Gen AI travel assistance. How do you think about taking your leading supply that you have maybe partnering with hotel partners to create a really differentiated top of funnel alternative and hotel booking assistant using all these large language model capabilities?

Yeah, so, Brian, let me let me talk a little bit about our marketing spend. Let me just back up before I talk about Q3 and remind you of the full year guide that we provided back in February. What we shared in February is that, for the full year we were looking to deliver an EBITDA margin of a minimum of 35%, which was obviously down slightly from the nearly 37% we delivered in ‘23. And the intent on guiding to margin compression on a year-over-year basis was to allow us the flexibility to invest in growth. And what you've seen so far this year is that for H1, marketing as a percent of revenue was effectively flat with where it was in ‘23. But we do intend to lean into those growth investments in the back half of the year starting in Q3, and that's obviously what informs the EBITDA guide that that you saw in the letter. In terms of where we are leaning in on marketing in particular and the confidence around the various channels, let me just talk about a couple of the components of the increase in marketing. So first, consistent with the conversation Brian Chesky just had on international markets. What you'll see in Q3 is that we will be layering on a handful of incremental markets that we will be targeting and effectively turning on our global playbook. In particular, you'll see us try or intend to extend our success that we've seen in Latin American countries like Brazil and Mexico to other markets in that region. Places like Peru, Colombia, Chile, Argentina so there will be some layering on of those incremental markets. We feel like we have had pretty good success there. Obviously it takes time in terms of investments in a market both from a product perspective as well as a marketing perspective to reaccelerate growth. But as the results have shown in terms of the differential between growth rates in our expansion markets and our core markets we feel like our expansion efforts have been successful and so, rolling them out to incremental markets will be helpful over the medium term. In terms of incremental performance marketing, what we've shared with you today that has continued into Q3 is that based on a lot of optimizations that we've made to our performance marketing efforts. We've been able to maintain extremely high efficiencies and so where we see those we do lean in and have quite high confidence in terms of returns.

And why don’t take your second question. So Brian Gen AI ChatGPT launched late November 2022. When it launched, I think we all got like incredibly excited. It was kind of like the moment probably some of us first discovered the Internet or you know maybe when I come with launch. And when it was launched you had a feeling that everything was going to change. But I think that's still true. But I think one of the things we’ve learned over the last say 18 months or nearly two years 22 months since ChatGPT launched is that that’s going to take a lot longer than people think for applications to change. If I were to think of AI, I'd probably think about it in three layers. You have the chips. You have the models. And you have the applications. There has been a lot of innovation on the chips. There has been a lot of innovation on the models. We have a lot of new models and there's a prolific rate of improvement in these models. But if you look at your home screen which of your apps are fundamentally different because of the AI? Like fundamentally different kinds of generative AI, very little especially even less in e-commerce or travel. And the reason why is I think it's just going to take time to develop new AI paradigm. ChatGPT is an AI model – interface if that could have existed before AI. And so, all of our paradigms are pre-AI paradigms. And so what we need to do is we need to actually develop AI applications that are needed to the models, no one's done this yet. There's not been one app that I'm aware of at the top 50 app in the app store in the United…

And your next question comes from the line of Justin Post with Bank of America. Your line is open.

Great thanks for taking my question. Just on the North America and Europe markets presumably growing a little slower than the average for the company. Any signs of kind of cyclical or macro pressure like shorter trips or people trading down that that could end in and any that could maybe drive some acceleration when the period ends. And second, how do you feel about your market share in those two key regions? Thank you.

Yes, so let me talk. Let me talk a little bit about what we're seeing in both, North America and EMEA. I would say I would go back to my prior comments in terms of just the lead times. That that commentary is true globally so it applies to both northern - North America and EMEA. I would say EMEA has been relatively stable quarter to-date. And so it is not necessarily part of the broader moderation story that we have shared. In terms of North America, there's a handful of components. One is the shorter lead times I would say. A second is North America has a concentration of our long-term stays, nights and what we've seen over the last year is that short term days have grown more quickly than long term stays. And so, the LTS to growth rate is a drag on the average that has an outsized impact on North America and we've just comped with the changes that we made a year ago in terms of our LTS fees which is a bit of a headwind for LTS generally on the platform, but in particular in North America The one other thing I would add in terms of just providing some color on what's happening in the US is couple of regulatory comments. One in particular that we're watching is that in California, the total price display and cancellation grace period, regulations went in went into place on July 1st and we think that's been a little bit of a headwind to our California business. Our California business if you include both guests who reside in California as well as guests who are travelling to California, which is what the new rule is applied to is about 10% of our GVV. So it’s an…

And your next question comes from the line of James Lee with Mizuho. Your line is open.

Great. Thanks for my questions. Two here please. First on experiences. What are some of the frictions and difficult problems you're trying to resolve here. It seems like you have plenty of supply, plenty of listings. So that doesn't seem to be that issue. Can you help us understand something key paint points for both suppliers and customers? And second, I once again noticed in North America and EMEA, you have call out that to see a mix shift to non-urban markets and just want to get some more color on that. Urban markets in general, are you seeing weaker demand or seeing increased competition in the hotels? Thanks.

Hey, James, I'll take the first question. So there's five things that we're looking for to do with experiences. The first thing is we want them to be a better price selection. Right now, we think we can have - we can offer more affordable experiences that younger people especially Gen Z could afford. So that's the first thing. We don't really have enough affordable listings. The second thing is, we need more unique inventory. It's really good. The inventory we have is good. In fact the five star rating average for experiences is higher than the five star rating for homes. But we still think we can have even more unique inventory that you could only find at Airbnb. That's not another platform and we want to recruit some of the most interesting people in the world to be on our platform. And we're getting a lot of excitement. The third is we think we can even merchandise them better. I think experience to see more and more insights like with film, with movie, with video. Imagine deciding on a movie but instead of a film trailer, you had some movie stills. Would you go see the movie, you probably wouldn't. You need a trailer. You need a video experience. You saw video first. The fourth it needs to be discoverable in the apps. Right now experiences are really hard to find because those the last four years we've really focused on prioritizing our core business. I mean a lot of people they come to our homepage they don't ever see experiences. You wouldn't know these sell experiences. So we're going to completely reimagine our search and discovery engines to cross-sell experiences after you book a home and to really target the right homes. We were going to show you other guests on the experience, just provide social proof. We're going to bring some of the magic like the countdown in the icons and some of the magic there. And the final thing is awareness for experiences really low. Most people don't know we offer experiences even though we launched them eight years ago. So we're going to actually market them and tell the world about them and we can do this without a lot of incremental investment because we can market homes and experiences in the same ad. So if we do those five things, I think we can dramatically change the trajectory of experiences business.

And James, to your second question, in terms of the mix shift to non-urban market. We call it on the letter because it is a differential in terms of the respective market segments, but there isn't – it’s not a major shift what we are seeing is that growth in non-urban markets continues to be slightly higher than that of urban. I think what that tells you is we have a - I would think differentiated offering in non-urban. And I think the interesting thing about that portion of our business is, it has maintained a - I would say meaningful larger share of our business demand four years post covid than it was previously. And I think over the last four years has been a broadening awareness of the variety of markets that Airbnb is available that hotels simply don't exist and we continue to see great demand for those markets.

And your next question comes from the line of Justin Patterson with KeyBanc. Your line is open.

Great. Thank you very much. Ellie, I appreciate your comments on margins and real flexibility to invest this year. Could you talk about how long we should see this investment cycle persist and when we could start seeing more meaningful returns? Thank you.

Yes, thank you. So we always have not given a guide for ’25. We will provide you a view on ‘25 as it approaches. What I would say is, if you look at where we have come over the last couple of years, we obviously delivered a substantial amount of margin expansion from where we started. You followed us for some time, but pre - going public we had negative EBITDA margins and four years later, we were able to deliver almost 37% margins last year. So I think we've more than demonstrated the strength of this model both from a profitability basis as well as a free cash flow basis. What we'd like to deliver more of is growth and that's why we have as I said a lower margin target for the current year. And as I said previously, you'll see us start to make those investments in the back half of the year. I anticipate that when you think about both our medium term growth lever of international markets and then what long-term growth lever of expanding the core offerings. Those will require some ongoing investments in order to scale and then deliver the growth. What I think you should also think about though is that all of our expansions to-date have not been very capital intensive. So we will use some of the probability to invest but we don't anticipate any kind of sea change in the foreseeable future around overall profitability levels.

And you're next question comes from the line of Kevin Kopelman with TD Cowen. Your line is open.

Great. Thanks a lot. So, if we adjust our Easter impact it looks like you have a little bit of revenue growth slowing kind of each quarter this year expect to see the third quarter. Based on the dynamics you're seeing today do you anticipate some further slowing towards the end of the year, if you look at how space are shaping up for Q4 or do you see anything in your numbers as of now that could lead to stabilization? Thanks.

Yes. thanks, Kevin. So I would say, first, we're not going to provide outlook right now for Q4, but when I when I give you that color on the lead times, I think it's pretty informative from the perspective of, it's not that people are not definitively booking over the long term, if they may not have booked yet. And so, as I shared previously, we have seen some. some movement in lead times over the last couple of years and in many cases people have come booked. They just come and booked at a later time period and so that's certainly something that we will be on the eyes out for in terms of Q4 and beyond. I think also just thinking about how the comps play out for the balance of the year. As you'll recall where we were last year September and October were quite soft and then November and December had a bit of a rebound. So those are the comps that we'll be lapping as we approach the end of the summer heading into Q4.

And your next question comes from the line of Nick Jones with Citizens JMP. Your line is open.

Hey, thanks for taking my question. Maybe just another one on an expenses and philosophically how you're thinking about it. There's plan to relaunch experiences, Brian it sounds like there's not a lot of incremental investment required there, but earlier you kind of talked about launching new products and services every year. So I guess can you speak to how nimble you plan to be with the investment cycle to if demand may be continues to get weaker or versus kind of bouncing back, how should we be thinking about kind of the level of commitment to invest in and what sounds like a lot of new and exciting products and services?

Yeah, I mean we essentially built our forecast to have already have a spread of that between short term, medium term and long term. So in the short term, I mean, the biggest driver of growth in the short term again is conversion increases. Every 1% increase in our business is about $100 million. And we have hundreds of basis points of growth opportunities just in conversion and usability improvements. And then affordability we have quite a few opportunities and then a quality and reliability. Probably one of the biggest variables might be like how we think about expanding internationally like some of the big Asian countries like Japan, we can be very, very nimble. based on the results of Japan. Most of these new services and offering though are going to not cost very much. They're mostly headcount we're talking some teams hundreds of people not thousands of people so you won't really see that. Because this is a network effect business and most of our traffic is going to be taking traffic we already have for accommodations business and cross-selling new offerings. And so, it's really just the cost of acquisition of supply and that's not very expensive because we've found that we can do it fairly efficiently. So most of this it's very nimble. There's not going to be a lot of incremental investment that would materially change. The variability is sometimes it’s probably like marketing especially internationally that's a question.

And your next question comes from the line of Jed Kelly with Oppenheimer. Your line is open.

Hey great. Thanks for taking my question. Just going back to the urban opportunity and potentially putting more hotels on your platform, can you just talk about philosophically how the company balances putting more supply that you might consider more could commoditize and that can be cross-listed. What that might convert at a higher rate? Thank you.

Hi, Jed, so, essentially, I think people come to Airbnb because they want to get something unique. That's what customers think of when they think of Airbnb. That's why we're a noun and a verb. We're one of the only brands in the world like Kleenex or Xerox, that's a noun and verb and it means you can - it's something that didn't really exist before we created this category at a wide scale. That being said, for everyone who books in Airbnb, about 9 people book a hotel. And so, if we can get just one of those guests to book on Airbnb, that's currently booking on a hotel platform we would go from nearly half a billion nights a year to a billion nights a year. And there's two ways to do that. One is the increased reliability of homes in Airbnb, because the number one reason people tell us they book hotels is they are typically more reliable. They know what they're going to get they have a front desk. The other is adding hotels in Airbnb and we're not philosophically misaligned with adding hotels, if we were we would never bought hotels a night before the pandemic. We just haven't prioritized hotels. We think of hotels as a filling in network gap during high occupancy nights. We generally think our if there's an incredible home at a low price, they're always going to choose that but when occupancy goes up they are going to go towards hotels. There are also some use cases where hotels are better and Airbnbs are better. If you need to stay for one night, you're travelling alone, you are business travel and you plug in you plug out a hotel is better. If you're traveling with a group you are travelling for more than three nights and you're travelling in the non-urban area, Airbnb is better. And then, if you're doing something between then you're going to have choices. So, we do think between filling in a network gap and getting more of those one night business travel stays, there is an opportunity to offer hotels in Airbnb and we have a lot of hotels. We have hundreds of thousands of boutique hotels and non-home inventory on Airbnb and we're going to continue to expand that over its years to come. And so there's no philosophical misalignment to add commodity inventory. The philosophical misalign would be if that becomes the majority of our marketplace and people - consumers stop thinking of Airbnb as unique and local. If they start thinking about us that changes the brand then that would be a philosophical misalignment but I don't see that happening anytime soon.

And your next question comes from Mark Mahaney with Evercore ISI, Your line is open.

I just wanted to ask a question about Paris and the learnings you've had from this. I assume this is the biggest event for Airbnb and a massive popular event in your largest city. So just if that’s true and I think that is, just step back and talk about the learnings of being able to make sure you had enough supply working with local regulators and agencies and in terms of getting messages out to opportunities out to guests as well like this big event that you've pulled off. Just talk about the lessons you've been able to draw from that that'll you know help you set you a better for the next FIFA World Cup and the next World Cup, next Olympics et cetera?

It’s a great question, Mark I'm really glad you asked this. I just want to like take us back down memory lane because in 2007, Airbnb provided housing for a design conference. Then in 2008, we provided housing for the Democratic National Convention. Then in 2009 we provided housing for the inauguration. Our first three moments when we started Airbnb was provided housing for events. In fact, our original premise of our business was at housing for events. It wasn't meant to be ever offered for anything other than events in conferences. And the reason why is because conferences and events especially things like the Olympics and World Cup are unbelievable use cases for Airbnb. And the reason why is I think obvious to everyone. Events typically like to host more guests than they have hotel rooms available for. And people, most people they have, most regular people aren't looking to become Airbnb host and make a long-term commitment to host every week. So a lot of people events coming to town is wanting to host one week and make $1,000 or $2,000. And so what we did is we focused a year ago on Paris. And in the last year we increased our supply in Paris by 37%. We now have nearly 150,000 homes in Paris. We had 430,000 guests stay in Paris so far and counting and that number to continue to climb. So that's equivalent of five Olympic stadiums, I want you to imagine five Olympic stadiums where the guest staying in at Airbnb. The fact is that the Olympics as we know it could not ever happen again, without Airbnb because this 400,000 could not have stayed in a hotel room. And so to do that, what we did is we worked at the City of…

And your next question comes from the line of Stephen Ju with UBS. Your line is open.

Okay. great. Thank you. Brian, I want to ask on Airbnb rooms. I would have thought that given its more nascent statement in the economic backdrop that this is should probably be the product that should be growing the fastest. So is there anything that you can call out in terms of product fit or awareness? I think I heard you call out maybe supply shortages earlier. But any factors that might be weighing on the growth rate here a little bit? Thanks.

Thanks. Yeah, the reality is the biggest issue with Airbnb rooms it’s just a small percent of our business. It's a very small percentage. So even if it - even no matter how fast it grows it's often very small base. It's how Airbnb started by providing a room and a house. It's very affordable. It's very popular for Gen Z, but it is off a very small base and so you're not going to see a major change to the growth rate of the company based on that. I think the thing but maybe just broad zooming out though, two points I’ll make. The first point is Airbnb is one of the most diverse businesses in the world. We have bedrooms and homes up to tens of thousands of dollars a night luxury villas in Airbnb. We allow you to travel by yourself or with the large groups of up to 16 people. We're in every country nearly in the world, every continent in the world including at one point in article and so we're a very - we're in urban areas. Where in the decades arounds this nations we're off to be impact. So our general philosophy is that something for everyone to have the most diverse array of inventory in the world. The other point I'll just make is an area down the road that would really help Airbnb rooms is continuing to invest in our system of trust. The biggest obstacle to people staying in a room is just the discomfort with staying at a house with a stranger they don't know. One of our core inventions with a system of trust and as more we invest in system of trust, I just gave a lot more of these businesses where strangers to live in the others. So I do think it's still a big long term opportunity for us. But it's often but smaller base and it's never going to be as big as entire home and everything.

And your next question comes from the line of Lee Horowitz with Deutsche Bank. Your line is open.

Great, thanks. New on one our nights and on pricing. So Ellie you're talking about putting more investments into place in the second half of this year as a means of accelerating growth. Can you help us better understand sort of the payback periods that you tend to expect on these dollars and over what timeframe you may assess the ROI on these investments in terms of accelerating total company growth rates? And then maybe one on ADRs. You guys are highlighting sort of some building demand pressures in North America, all sign the pointing towards people trading up the whole homes and persisting ADR growth for your entire business again despite weaker growth in your highest ADR region, North America. I guess when we think about. the sustainability of ADR growth beyond the 3Q as you mix away from North America and perhaps see the overall travel demand environment continue to soften, how do you think about your ability to continue growing through that kind of a scenario? Thanks so much.

Yeah, so first let me talk about marketing payback. I would say the way we are looking marketing paybacks is very different based on the channels and investment from a performance marketing standpoint obviously the ROI is very specific and relatively short-term. We think about that in terms of weeks and months not quarters. In terms of Brands we think about that over a longer time horizon. If you think about any particular brand campaign, it needs to be in market for quite some time and it needs to be sustained for you not only to see the benefit, but also sustain the benefit and convert it into actual transaction. So I think about that more from the six months to a year payback period and requires - I would say a consistent level of investment. And then, as a third factor something that I mentioned in terms of an area of investment that is not programmatic. We do need to at the margin build some of our teams that are driving this growth and so that will be in a gradual investment modestly above the headcount growth that we've been targeting over the last couple of years but we think it will help long Payback should I should say high payback in terms of driving acceleration across a variety of initiatives. In terms of pricing, I think there's one question about what is happening at a geo level. I think there's a broader question in terms of the aggregate or global ADRs. To your question in terms of if neighbor is softer than other regions what happens to global ADR obviously mix shift is a huge component in terms of the global ADRs that we report. One Factor in terms of the Q3 guide is the shift a little bit away from North America which as you highlight does have the highest ADRs Over time we would anticipate that as regions like Latin America and APAC become larger portions of our overall business, the global ADR would come down. But those incremental nights are all accretive and the economics behind them still are very strong. So it's a at a global basis, we are we're somewhat agnostic because we can deliver strong economics across a wide range in ADRs.

And ladies and gentlemen, that will conclude our question and answer session. I will now turn the conference back over to Brian Chesky for closing remarks.

Alright, well, thanks for joining us today. Just to recap, revenue was 2.7 billion 11% higher than a year ago, adjusted EBITDA was a Q2 record And our a trailing 12 months free cash flow was $4.3 billion is our highest yet representing a free cash flow margin of 41%. And we've made significant progress over the past few weeks, but there's more to come. In October we're going to share with set of features and upgrades as part of our 2024 winter release. This includes expanding host of co-hosting, setting the stage for host provided services and much more. I'm proud what we accomplished in Q2 and I look forward to sharing more with you next quarter. Thanks for joining.

And ladies and gentlemen, that concludes today's call and we thank you for your participation. You may now disconnect.
