Good afternoon, everyone. Early in my career, I used to write a plan that told my team what we were going to get done during any given cycle. Then at the end of the cycle, I would go through the dock and color every sentence of the plan, green, yellow or red, based on whether we had done what we said we would do and if we were on track to go where we wanted to go. I kind of always found it useful to write things down so you can hold yourself to account. With that in mind, I'd like to remind you of the last financial open house. In my first open house, I told you that we had a 4-step plan to turn Opendoor around with renewed energy. Let's go back in time and listen to what I said. So here's our 4-step plan to channel that energy. First, by the end of next year, we will drive Opendoor to breakeven. We think about this in terms of adjusted net income on a 12-month go-forward basis. That means Opendoor will start generating cash and will never be forced to raise equity ever again. Second, we will drive significant positive unit economics while increasing the velocity at which we transact in homes. This includes launching financial services like mortgage. Third, as we increase our unit economics, we will change the company's focus from primarily building channels to transacting directly with buyers and sellers. We're also going to focus on reducing our days in possession rather than arbitrarily increasing spread, which has had genuine significant negative consequences for us. Fourth, once we've accomplished the first 3 steps, we're going to focus on allowing buyers and sellers to transact on Opendoor without having to buy or sell from Opendoor. This is going to significantly lower our capital risk, but more importantly, it's going to give folks options they want. Today, I want to grade Opendoor against these 4 steps. And then I'll give you some details. Here's the bottom line. We did what we said we would do. But let's go through this line by line. So we're on track for our first step. We're driving Opendoor to be adjusted net income positive by the end of 2026 on a 12-month go-forward basis. The goal is simple, start by generating cash and never be forced to raise equity ever again. Second, since September, we've increased our acquisition velocity by 300%. We bought 537 homes last week alone. In the last -- the third quarter, we did only 128. And we grew while we drove significant positive unit economics. This improvement is a result of deliberate change to our product, our pricing strategy and our operations. Most importantly, our October 2025 cohort, which is the first full cohort under Opendoor 2.0 and it's the first one with enough sell-through data is performing really well. I'll get back to this in a second. Third line, we grew our DTC acquisition contracts while reducing our average days in possession. Comparing this last week to the last week of the third quarter, we've grown our DTC acquisitions by almost 700% and reduced our days in possession by almost 25%. Fourth, we've made it easier for sellers to choose the path that works best for them. And increasingly, they're choosing our capital-light product, Cash Plus. In the last week of Q3, Cash Plus was about 19% of our total contracts. Last week, it was 35% of a much higher volume. To give you a sense, Cash Plus was over 600% bigger last week than it was in the last week of Q3. This is the first step towards our goal of allowing buyers and sellers to eventually transact directly with each other. Christy is going to go through all the details of all the financials. But before she does, I want to say this. We laid out a plan for you. We're going to turn this company around, and we laid that plan out during Opendoor 2.0's first open house. That plan is working. We're green all across. We're already delivering results and are on track to deliver against our mission. In a minute, I'm going to tell you a lot about our product changes and all the things we've done since Q3. I'm really proud of how fast our team is moving and how much we're shipping. And the list I'll tell you about is a public CEO's dream. It sounds good in the script and it looks amazing in a pitch deck. But look, I know what this sounds like. New products, expanded TAM, ops improvement, pricing efficiencies and a bunch of business school words like strategic operationalization of North Star paradigm shifts with best-in-class synergy. Oh, flywheel. Look, I get it. Every public company does a stupid dance that pretends, folks can't look at the slope of a graph. One of my favorite investors, -- Sir John Templeton, used to say the 4 most dangerous words in investing are this time, it's different. So I'm not going to sit here and say random school words and ask you to believe that this time is different. This time, I'm going to show you. Our October acquisition cohort, which is the first cohort of Opendoor 2.0 that has had reasonable sell-through data is on track to be the most profitable October cohort in company history. Again, when it comes to the key metric that matters, our contribution margin, October 2025 is on track to be the most profitable October since Opendoor was incorporated. And we achieved this in the middle of the most aggressive market expansion in Opendoor's history. Given that this isn't really the strongest housing market, this performance, I think, shows a structural shift in how we operate, a shift that I genuinely think will be durable across macro cycles. We are no longer a prop desk. We're now a market maker. And I want to put a finer point on this cohort. What makes this cohort significant isn't just the margin level. It's the shape of the cohort. From 10% to 50% sold through, our margin degradation relative to home price appreciation has been the lowest of any cohort in our history, not any October cohort, any cohort period. That the October cohort is going so well is not a plan. It's a proof point. The product launches I'm going to talk to you about aren't promises of things that might work. They're the explanation for why October happened and why it's repeatable. Now look, because we're committed to transparency, let me get ahead of a couple of things. October was not our largest cohort by volume. But it was about double the size of what we were doing just a few months ago. We're not getting lucky on a few homes in a friendly market. And given how the past few weeks have gone, I believe we're on track to significantly increase our acquisition size as we said we would do. What October shows is that the structural changes we made under Opendoor 2.0 are working. And then we're compounding those learnings into every single cohort going forward. We have a lot left to prove. I know that. But for the first time, we're not asking you to take our word for it. This is a new company. Look, the way I think about my job is that my job is to build Opendoor as those product. Just like Tesla builds robots that build cars, my job is to build the tools and the systems inside Opendoor that help us build a great product. In the last few months, we've made a great deal of progress on this front. I don't want to spend a lot of time talking about this, but I kind of want to take a second to talk about the most important part of it. As Vinod Khosla says, the team you build is a company you build, not the plan you make. Today, 18 people report to me at Opendoor. Of those 18, 10 didn't even work at Opendoor a year ago. Our 10-K filing has a list of our executive team, and you can take a look at it. Not a single one of those people on that list was in our last filing. Since I joined Opendoor, we have a new Chief Operating Officer, a new CFO, a new President, a new Chief Growth Officer, a new Chief People Officer and a new Chief Business Officer. This is a world-class leadership team that I would put up against any other tech company. And on top of this, Opendoor 2.0 is the single most AI-pilled company in the public market that I know of. Let me give you an example. Not that long ago after we bought a home, someone on our team would set their desk and manually pull up data from 5 different systems, things like property records, inspection notes, HOA docs, pricing history, contract terms, stuff like that. And they would copy these things field by field into a seller disclosure PDF. It took hours per home, every single time. Last week, someone at Opendoor shipped an AI workflow that does all of this kind of automatically with no humans in the loop. It queries our data warehouse, cross-references inspection history and generates a plain English disclosure summary, fills a compliance PDF and then sends it up for review. But here's the best part. Other companies talk about how AI native their engineers are. The person I just talked about, that person is a non-engineer. He works on our ops team. He built this in his spare time in a week, no ticket field, no sprint planned. No one asked them to do this. He understood this simple fact. It's war time. And our primary weapon is our ability to prompt machines to create a new world. And he's not the only person doing this. Our ops team, sales team, compliance teams, they're all building their own tools now. Now if this is what our ops team does, I want you to imagine what our engineers are up to. So when I say we default to AI, I don't mean engineers use Copilot. That's not what I mean. Opendoor is a different type of company. It's a company where everyone, everyone is learning how to think like an engineer. Okay. With that, let's talk about what we built. We shipped a lot in Q4. I'll try to move through this fast, but I want you to see how what we shipped caused the October results. We shipped across 3 fronts, better products, bigger markets and stronger margins. And we did this, well, faster. First, we made our products better for buyers and sellers. For years, years, Opendoor's product was a one-size-fits-all product. You want to sell a home, here's an offer, take it or leave it. But look, all sellers are not the same. Someone with 80% equity in their home doesn't have the same needs as someone with 20%. But under the old model, both of these folks paid the same fee, which means that we're taking on risk and neither side wanted. The seller didn't need it and we didn't want it, but the product forced it. That's not a pricing problem. It's not an underwriting problem. It's a product problem. So we fixed it. We now put the ability to change the offer that fits your needs into your hands. You choose how much cash you want upfront and the fee adjusts, take less upfront, pay less fees, often a lot less. Every dollar that a seller does not need upfront is a dollar that we don't need to put at risk and a dollar that they don't need to pay for. So they pay less and we make more. It's a win-win. And it also allows us to serve customers that we could have never served before. This risk reduction, it allows us to do something else, too. It allows us to tighten spreads on our core cash product. It's early, but from best I can tell, this is working. We're seeing demand that we would have never seen before. And because we're seeing a lot of extra demand, we also launched our self-assessment app. With our self-assessment app, the seller takes pictures of their home and AI does the assessment work. No humans needed. And because there are no humans in the loop, in January, we nearly doubled the number of homes that we assessed compared to September. And so far this month, about half the homes we've assessed have needed 0 people to show up at your doorstep. On top of this, we expanded our buyer products, Opendoor Checkout. As of this morning, it is now live in 40 states. Opendoor Checkout embeds mortgage preapproval directly. It also supports Opendoor's Euros home credit where we give the brave men and women of America's Armed Forces $4,000 towards closing costs of a home. Opendoor Checkout also includes the Opendoor guarantee. It allows for free cancellation, warranty and early move-in. We also launched our seller guarantee. When a seller sells us a house using Cash Plus, they now get the chance to make sure they like how we are selling the home. If they don't, they can just undo the transaction and pick the home back by paying us a low restocking fee. Okay. That was a core product. Outside the core product, we also expanded our growth levers. To start, we dramatically expanded how many people we could serve by expanding our geo coverage and our buybox. It took Opendoor from 2015 to 2025 to become available as an option for about 1/3 of the homes in the U.S., 10 years. Opendoor 2.0 almost tripled that in about 10 weeks. Thanks to AI, our product went from being available to about 1 to every 3 homeowners to being available to nearly every homeowner in the Lower 48. Now you would expect that, that kind of rapid expansion would reduce risk, sloppy underwriting, margin compression, operational blowups. We saw the opposite. You'll hear Christy talk about our margin guide points in a bit, but the new system is working, and it's already generating thousands of incremental qualified leads per week with 0 incremental marketing spend. Making this work well required us to build across almost 200 MLS data sets, coordinate over 100 brokerage regions and expose 150 standardized attributes. This was hard work, but we believe software should not be limited by
