Consumer travel-booking platforms whose paid-search-funded funnel is the sector's most direct AI exposure.
Booking Holdings generated roughly $172B of gross bookings and $23.7B of net revenue in FY2024; Expedia Group booked $108-112B gross against $13.7B net — take rates near 13-15% in both cases, separating what travelers pay from what the platforms earn. No segment in the sector has more direct agentic-AI exposure, because the exposure runs straight through the funnel these platforms buy: a large share of the traffic they purchase through paid search simply does not exist if travelers query an AI agent instead of a search engine.
Booking Holdings, Expedia Group, Trip.com and Airbnb account for the large majority of leisure online travel bookings — Booking weighted to Europe, Expedia to the US, Trip.com dominant in China — with a long tail of metasearch sites and niche OTAs around them. Growth runs high single digits, tracking global leisure travel demand broadly. Upstream, the platforms aggregate inventory from hotels, airlines and activity suppliers; downstream, an increasing share of traffic arrives via metasearch engines rather than direct navigation. The economics are asset-light and high-margin: a take rate applied to gross bookings, with no underlying travel asset owned.
Follow the paid-search line. Booking and Expedia each spend roughly $6-7B a year on search advertising to win the click that starts a booking — spend with no purpose once a consumer's query goes to an AI agent instead of a search engine. Under pressure alongside it is the merchandising layer built on top of that funnel: cross-sell, insurance upsell, and the rest of the post-click monetization that depends on a human browsing a results page. Shift booking activity toward agent-to-agent commerce transacting directly against supplier APIs, and online travel agencies end up competing on inventory breadth and fulfillment reliability rather than on search-results placement and on-page merchandising. That is a narrower and more commoditized basis for competition, and it pays less.
The platforms are answering from two directions at once: a push into corporate travel booking tools, which is expansionary, and a build-out of direct-connect API relationships with suppliers, which is defensive — intended to cut the distribution fees paid to intermediaries higher up the chain. A new competitive layer is also forming, an agent-orchestration and booking function distinct both from the classic consumer OTA interface and from the legacy global distribution systems that predate it. Google's 2025 shift toward agentic search results already shows in early funnel data; the fuller effect on paid-search economics and booking-agent market share plays out over 2-5 years.
