Expedia's AI Bet Is Working... But the Real Question Is What It Costs You Per Booking

Let's talk about what Expedia actually just told us. Q4 2025: revenue up 11% to $3.5 billion. Gross bookings up 11% to $27 billion. Booked room nights up 9% to 94 million. Adjusted EBITDA up 32%. Those are real numbers. That's not a company struggling to find its footing... that's a company executing.

But here's what caught my attention. Their B2B gross bookings jumped 24% to $8.7 billion in Q4 alone, while B2C only grew 5%. Read that again. The business-to-business side is growing almost five times faster than the consumer-facing side. That's not a footnote. That's a strategic pivot. Expedia is becoming the pipes, not just the storefront. They consolidated from 21 different tech stacks down to one, cut cloud costs by more than 10%, and now they're pushing Vrbo's 900,000+ vacation rentals through their Rapid API to partner networks. They're embedding themselves into distribution at the infrastructure level. And when a platform becomes your infrastructure, switching costs go up. Way up.

Now let's talk about the AI piece, because that's where it gets interesting (and by interesting I mean complicated for anyone running a hotel). CEO Ariane Gorin is saying generative AI is "reshaping how travelers do trip discovery." Okay. What does that actually mean for your property? It means Expedia is building conversational tools, natural-language search, AI-powered filters, and an AI agent inside Hotels.com. They're also making sure their brands show up in AI-powered search and work with agentic browsers... the kind of tools that book a trip for you based on a conversation rather than a search query. Here's the thing nobody's talking about: if a traveler says to an AI agent "find me a clean hotel near downtown Nashville under $180 with free parking," the ranking factors that determine whether YOUR hotel shows up in that response are completely opaque. At least with traditional OTA search, you could see where you sat in the results and game the system a little. With AI-mediated discovery, you're trusting the model. And you have no idea what the model weighs. I talked to a revenue manager last month who told me she's already seeing booking patterns she can't explain... rate sensitivity that doesn't match her comp set, sudden spikes from channels she didn't even know were active. She said it felt like "someone else is driving my car." That's what AI-mediated distribution feels like at property level.

And Expedia knows AI is a double-edged sword. Their own 10-K filing now lists "generative and agentic AI" as a competitive threat and explicitly names companies offering AI agents as a competitor category. They're simultaneously building AI into their product AND admitting that AI could disintermediate them. That's not paranoia... that's accurate. The worldwide spend on AI in travel is projected to hit nearly $14 billion by 2030 (up from about $3.4 billion in 2024). Expedia is betting they can ride the wave instead of getting crushed by it. Their direct selling and marketing expenses were $1.7 billion in Q4 2025 alone... up 10% year-over-year. Somebody's paying for that marketing spend, and if you think it's not flowing through to your cost per acquisition, check again.

Here's what this means if you're running a hotel. Expedia's growth is demand. Demand is good. But demand through an increasingly AI-opaque, increasingly consolidated distribution partner comes with strings. The B2B growth means more bookings are flowing through white-label and API channels where you might not even know Expedia is the originator. The AI tools mean guest discovery is shifting from search-and-compare to ask-and-receive, and the algorithms deciding which properties get recommended are black boxes. And the 100-125 basis points of EBITDA margin expansion Expedia is guiding for 2026? That margin has to come from somewhere. Either they're getting more efficient (possible... they've done real work on their tech consolidation), or the economics of being a hotel on their platform are shifting. Look at your channel mix. Look at your cost per acquisition by channel. Look at the percentage of bookings coming through paths where you can't see the full funnel. If those numbers are moving in a direction you don't like, you need to act now... not after the next contract renewal. Because once you're the infrastructure, they set the terms.
