Booking Holdings Inc.

Booking Holdings Inc. is the world's largest online travel company by revenue and gross bookings, operating Booking.com, Priceline, Agoda, KAYAK, and OpenTable across more than 220 countries and territories. In fiscal 2025, the company generated $26.9 billion in revenue on $186 billion of gross bookings, booked 1.24 billion room nights, and produced $9.1 billion in free cash flow — all records.

This is a story about a business that looks, on the surface, like a mature cash-return machine — aggressive buybacks, a newly initiated dividend, operating margins approaching 35% — but whose long-term trajectory turns on a genuinely open question: whether Gen AI disintermediates the online travel agency model or cements the incumbent's advantage. The company is betting the latter, investing heavily in its Connected Trip vision and Gen AI capabilities while running a transformation program extracting $550 million in annual cost savings. The market is pricing the stock as if it is not sure which way the coin lands.

The file turns on a handful of debates: whether the marketing spend can ever meaningfully decline as a share of revenue, whether the Connected Trip is a genuine moat-builder or a margin-dilutive distraction, whether Booking.com's dominant position in European accommodations is durable against regulatory and competitive pressure, and what normalised earnings power looks like given the one-way shift toward merchant bookings and the aggressive pace of share repurchases.
