ChatGPT ads for hotels: what they cost and if they pay off
On 9 February 2026, advertising entered the conversation: OpenAI announced that day that it was beginning to test ads inside ChatGPT in the US, and travel was among the pilot verticals from the start, alongside retail and consumer goods. For an industry that has spent two decades buying visibility on Google, the question arrived on its own: is it time to bid inside the chat as well? In February the answer was "you can't". Eight months later it is "yes, and cheaper than you expected" — which is exactly when it pays to think before spending.
How they work
The design is deliberately cautious. Ads appear clearly labelled as sponsored and visually separated from the answer, not inside it. They are served from systems independent of the model, and OpenAI commits in writing to them not influencing what ChatGPT replies: you cannot buy your way into being recommended.
On who sees them there is a detail almost everyone gets wrong, and it is worth pinning down: it is not "free users only". Ads appear on the Free plan and on the Go plan, which is paid. The ad-free plans are Plus, Pro, Business, Enterprise and Edu. And there is a little-known way out: free-plan users can switch ads off in exchange for fewer daily messages and without some tools, such as image generation.
That design separates two markets worth keeping apart: the answer, which is earned through quotability rather than money, and the ad slot below the answer, which is bought. The distinction is exactly the one Google maintained between organic results and ads — and we already know that film's script.
The context that changes everything: a handful of slots, not 30
The structural difference with the classic search engine is not the ad format but the shop window's arithmetic. A Google search returns dozens of results between organic and paid; a ChatGPT answer recommends only a handful of options. In that funnel, not appearing doesn't mean losing a click — it means not existing in the conversation.
That scarcity of slots explains why the pilot interested the giants so much. Expedia was among the first advertisers, and its CEO, Ariane Gorin, put it like this at the Q1 2026 earnings presentation: "In February, we went live with ChatGPT ads." Later she acknowledged that "traffic and bookings from AI-driven channels remains small", and that they are "encouraged by the mix of new users, conversion, and average purchase spend". On that same call she dropped a line worth more than the figure: answer engine optimisation is now their fastest-growing channel.
It also explains the OTAs' head start on the organic side: models feed on massive listings, recent reviews and transactional data — the material large platforms produce at scale. Whoever reaches the paid slot will arrive with that base as well.
Microsoft, meanwhile, has been serving ads inside Copilot since 2025, with formats designed for chat: a signal that the format is not an isolated OpenAI experiment but an industry direction.
How much does it cost to advertise in ChatGPT?
The most instructive thing about this channel is not how it started, but how fast it got cheap.
In February, entering the pilot required something in the order of $200,000 in minimum spend, with CPMs around $60. In April, OpenAI cut the minimum to $50,000 — advertisers coming in through Criteo were being offered $50,000 to $100,000 — and some agencies were seeing effective CPMs as low as $15. On 5 May, OpenAI opened a self-serve Ads Manager, in beta, with cost-per-click bidding alongside impressions and no minimum spend, suggesting a starting maximum bid of $3 to $5 per click.
In three months, the channel went from inaccessible to anyone who wasn't a multinational to open to a twenty-room hotel.
And the channel left the US a while ago: Canada, Australia, the UK and Japan came earlier. On 18 August 2026 it was Europe's turn — 31 countries, Spain among them — under the same rule: only on the Free and Go plans. On 31 August it opened the self-serve manager there, and that same day Dave Dugan, OpenAI's vice president of global ad solutions, said the business had reached $1 billion in annualized revenue in under 200 days. That is a run-rate figure (one month's billing multiplied by twelve), not booked revenue. By September ads were live in more than 60 countries, and in October OpenAI announced a test of image ads in ChatGPT Images, for now only in the US.
It is worth reading what that means. An advertising channel does not get that much cheaper because demand is overflowing: it gets cheaper because it needs advertisers. And by late April, agency executives interviewed by Marketing Brew were already describing travel as a somewhat crowded category inside the pilot.
So now what? My reading
Being able to advertise doesn't mean you should. For a small travel business, the sensible sequence still doesn't start with the ad:
- Organic first, because it is not for sale. ChatGPT's answer cannot be bought: it is earned with recent reputation, verifiable data and presence in the sources the assistant consults. Everything this blog has documented about quotability applies here unchanged — and it is the part of the shop window no rival budget can outbid you for.
- Before the ad, the landing page. This is the mistake that will cost a lot of people money. The paid click lands on your website, and if that site is slow, awkward to book on, or carries data that contradicts your listings, you have paid for a visitor who leaves. An ad does not fix a website that doesn't sell: it bleeds it faster.
- When you go in, go in as an experiment. With no minimum spend, testing costs little — a real advantage over the early years of Google Ads. But Gorin's words, with "small" traffic and encouraging conversion and basket size, are the honest description of an embryonic channel. Learning budget, not harvest budget, and measure from the first euro.
And a warning about how quickly all of the above expires: this channel has changed its rules at least five times in eight months. Every figure in this section — minimums, bids, available countries — is worth checking before you spend. The only thing that hasn't changed, and doesn't look likely to, is point 1.
The full picture
It is worth closing with the whole map: assistant monetisation is still mutating — OpenAI stopped taking payment inside the chat and found its route in advertising; Google processes bookings without being the seller — and no model has fully consolidated. On that unstable board, the only investment with no obsolescence risk is the usual one: that when a machine, with or without ads around it, talks about your business, it has verifiable, favourable things to say. Ads in ChatGPT are already one more channel to manage. Quotability is the precondition for that channel, and all the others, to have something to amplify.
