There are platforms that facilitate travel, and then there is Booking.com — a platform so thoroughly embedded in how the world finds, compares, and books accommodation that its name has become a verb in several languages. Founded in Amsterdam in 1996 and now operating as the flagship brand within Booking Holdings, it processed more than 1.2 billion room nights in 2025, a figure that represents approximately one in every seven hotel nights booked globally that year. In 2026, the company that built the world’s most used travel platform is deploying its most ambitious technological reinvention — and the decisions it makes this year will shape how hundreds of millions of travellers plan and book trips for the decade ahead.
The Scale That Makes Everything Else Possible
The numbers behind Booking.com in 2026 are the foundation on which every strategic move rests. At December 31, 2025, Booking.com offered accommodation reservation services for approximately 4.4 million properties in over 220 countries and territories and in over 40 languages, consisting of approximately 500,000 hotels, motels, and resorts and approximately 3.9 million homes, apartments, and other unique places to stay. The company booked more than 1.2 billion room nights in 2025, an increase of 8% year over year, and achieved $26.9 billion in revenues, up 13% compared to the prior year, with adjusted EBITDA of $9.9 billion reflecting a 20% increase.
That breadth — 4.4 million properties across 220 countries in 40 languages — is not simply a marketing headline. It is the structural asset that makes Booking.com genuinely difficult to displace: no competitor has assembled a comparable inventory at comparable depth, and the platform effects that come from that scale compound with every additional property listed and every additional booking made.
The Connected Trip: A Vision Becoming Reality
The strategic concept that defines Booking.com’s direction in 2026 is the Connected Trip — a vision of travel planning and booking as a seamless, end-to-end experience rather than a fragmented sequence of separate transactions. The goal of the Connected Trip vision is to offer a differentiated and personalised travel planning, booking, payment, and in-trip experience for each trip, enhanced by a robust loyalty programme that provides value to travellers and partners across all trips.
In practical terms, this means Booking.com is expanding aggressively beyond accommodation. In 2025, Booking.com offered flights in over 55 markets — a significant expansion of a product line that was still nascent three years earlier. The platform’s attractions and experiences business has grown equally rapidly, with management highlighting record growth in flights and attractions as part of the 2025 annual results. The ambition is to become the single platform through which a traveller plans, books, and manages every component of a trip — from the flight and hotel to the local experience and the restaurant reservation — with AI personalising the sequence at every step.
AI Is Now the Core Infrastructure, Not a Feature
Management highlights record annual room nights, rapid growth in flights and attractions, and expanding use of generative AI to personalise planning, support its Connected Trip strategy, and improve customer service. The financial impact of this AI investment is already measurable: customer service costs per booking dropped 10% in 2025, fuelling a $700 million growth programme for 2026.
That $700 million reinvestment — entirely self-funded through AI-driven efficiency savings — is being deployed across AI capabilities, Connected Trip infrastructure, regional expansion in Asia and the United States, advertising, fintech development, and loyalty programme enhancement. Booking targets revenue growth 100 basis points above its long-term goal, intends to expand margins, and plans $700 million in additional investments focused on AI, Connected Trip, regional initiatives, advertising, and loyalty programmes. This is a company confident enough in its AI efficiency gains to reinvest them entirely into growth — a strategic posture that distinguishes it from competitors still absorbing the cost of AI implementation without the productivity returns to fund expansion.
The Merchant Model Expansion
One of the most consequential structural shifts in Booking.com’s business is its expansion of the merchant model — processing payments directly from travellers rather than simply connecting them to properties. The mix of total gross bookings generated on a merchant basis was 67% in the first quarter of 2025, an increase from 59% in the first quarter of 2024. This shift matters for travellers because it enables more flexible payment options, greater currency choice, and more secure transaction terms. It matters commercially because merchant processing deepens Booking.com’s control over the financial layer of travel — a position that creates fintech revenue opportunities well beyond the commission model the platform was originally built around.
What This Means for Travellers in 2026
For the hundreds of millions of travellers who use Booking.com annually, the platform’s AI investments are already producing tangible improvements in search personalisation, customer service response times, and the depth of property information available at the point of booking. The expansion into flights and attractions means that the platform is increasingly capable of handling an entire trip rather than just the accommodation component — reducing the need to navigate multiple platforms, maintain multiple bookings, and manage multiple confirmation emails.
The platform’s Genius loyalty programme continues to expand its benefits structure, with discounts, room upgrades, and free breakfast offers building genuine retention value for frequent users. As the Connected Trip vision matures, loyalty programme members will increasingly benefit from AI-driven personalisation that learns from past trips to surface more relevant options for future ones.
Generative AI is accelerating innovation and reshaping how the industry advances its mission of making it easier for everyone to experience the world. For Booking.com, that mission is not a corporate slogan — it is a commercial imperative. The platform that processes one in every seven global hotel bookings cannot afford to be overtaken by AI-native competitors building from a blank slate. Its $700 million reinvestment, its Connected Trip architecture, and its merchant model expansion are the answers to that competitive pressure — and in 2026, they are beginning to deliver measurable results.
