The Agentic Booking Question No One Has Answered: Who Gets the Commission?

In March 2026, OpenAI made a move that barely registered outside the industry: it pulled Instant Checkout — its in-chat purchase button — out of ChatGPT's main interface and stopped processing travel transactions directly. Payment was handed off to third-party apps via its Agentic Commerce Protocol, and the assistant was repositioned toward discovery and research rather than checkout (Skift, March 5, 2026; PhocusWire, March 10, 2026). Expedia's and Booking's share prices rose on the news, GuruFocus reported. The market read it correctly: the company pushing hardest to sell travel inside a chat window had just admitted it still doesn't know how to get paid for it.

That retreat is the latest chapter in an eighteen-month acceleration. OpenAI and Stripe unveiled the Agentic Commerce Protocol in September 2025; Google followed with its own Agent Payments Protocol. In October, Booking and Expedia launched apps inside ChatGPT — reaching its 800-million-plus user base — while Google struck a payments deal with PayPal. In November, Google announced agentic booking inside AI Mode, and Booking's and Expedia's stock dropped between 4% and 7%. January brought Google's Universal Commerce Protocol and Accor's ALL app landing inside ChatGPT. By February, Marriott confirmed its bookings were processing through AI Mode, ChatGPT began showing ads, and Amadeus shares fell on the news, per Citi and Barclays data cited by Reportur. Every announcement has moved real stock prices. None has settled the economics underneath.

The clearest map of where this leaves hotels comes from David Val Palao's analysis in TecnoHotel (December 2025), which reduces agentic booking to three models already competing for the same transaction. The first is the familiar OTA wrapped in a chat interface: Booking, Expedia, Tripadvisor and Kayak open an app inside ChatGPT, and the hotel pays the exact same commission it always did — only the storefront changed. The second is the MCP aggregator, with DirectBooker as an early example: it pulls real-time rates and routes the booking to the hotel's own website, but introduces a new toll that didn't exist before. SiteMinder is hedging both sides of that bet at once — Demand Plus for direct sales (with DirectBooker as launch partner) and Channels Plus to keep feeding AI-powered OTAs — the same vendor collecting from both tables. The third, most disruptive on paper, is a hotel- or agency-owned MCP server with a canonical rate and inventory database that talks to the assistant with no intermediary at all. Mirai, Neobookings and Paraty Tech are already building toward it.

What none of the three models has resolved is the percentage. There is still no settled, verifiable commission structure for when an AI agent executes the booking on the traveler's behalf — and that gap is exactly where the real fight is happening. Brad Brewer, founder of Agentic Hospitality, warned in PhocusWire back in October 2025 that OTAs are positioned to replay inside AI assistants the same move they made in search: absent specific regulation, independent hotels will spend years paying, again, to reach their own guests. The nuance matters — the EU's Digital Markets Act, built to rein in dominant search platforms, doesn't yet treat AI assistants as a distribution channel subject to the same rules.

While the commission model stays unsettled, monetization is quietly migrating elsewhere: advertising inside the chat itself. ChatGPT's ads, launched in February 2026, already have Expedia buying and Marriott piloting. Tellingly, neither Google nor OpenAI wants to be the merchant of record on the transaction — both would rather the partner handle payment and keep its usual economics, while the platforms position themselves where the actual fight is: control of the conversation with the traveler, not the invoice for the room night.

I've spent fifteen years on the distribution side of group travel — ski and adventure programs sold through both B2B and B2C channels — negotiating commission terms with agencies, wholesalers and platforms long enough to recognize the pattern: commission was never really a fixed percentage so much as the price paid for not controlling the relationship with the end guest. That doesn't change because the party booking is an assistant instead of a person. If anything, it sharpens, because the assistant decides which options it shows and in what order, with less room for the kind of human negotiation a front-desk or call-center agent could still offer.

The question every hotel should be asking before signing an MCP integration isn't "do I need to be there?" It's which of the three models they're actually entering: paying the same commission under a new name, taking on a new toll in exchange for traffic, or building a proprietary MCP server to avoid depending on either. All three are legitimate choices. The only wrong answer is not knowing which one you've made.
