The ad-supported AI assistant is no longer an experiment reserved for the biggest brands. This week, Criteo — OpenAI’s first ad-tech partner — lowered the minimum spend for advertising in ChatGPT from $50,000 to $10,000 and announced it will match every dollar clients spend on the platform. It’s a small headline with a big implication: the answer engine is being seeded as a mass-market ad channel, fast.
The numbers in this piece
01What changed
When Criteo joined OpenAI’s advertising pilot in March 2026, the entry point was $50,000 — a number that limited ChatGPT ads to large advertisers running serious tests. This week Criteo:
| Dropped the minimum to $10,000 | , and |
|---|---|
| Pledged to match client spend dollar-for-dollar | effectively turning a $10,000 commitment into $20,000 of exposure. |
The stated goal is to “lower the barrier to entry and make testing dollars work,” expanding the pool of advertisers who can experiment — especially retailer and commerce brands. In parallel, reporting this week suggested OpenAI may lower its token costs, which would further reduce the economics of running ads and AI features at scale. OpenAI’s self-serve ads manager has also been opening up to more advertisers.
02Why marketers should care
- The entry price just dropped and the spend is being matched. Criteo, OpenAI’s first ad-tech partner, cut the minimum from $50,000 to $10,000 and will match every dollar clients spend. That is a subsidised window to learn a new channel cheaply.
- A dollar-for-dollar match is a bid for share, and it ends. The economics you measure during a subsidy are not the economics you will buy at later. The useful thing to capture is the mechanics, not the CPA.
- It is a commerce and performance channel now. Cheaper access and easier testing point the same way: this competes for lower-funnel budget on lower-funnel terms.
Lowering the ChatGPT ad minimum to $10,000 and matching spend isn't really about Criteo's revenue this quarter.
03What marketers should do
04The bottom line
Lowering the ChatGPT ad minimum to $10,000 and matching spend isn’t really about Criteo’s revenue this quarter. It’s about turning the world’s most-used AI assistant into an everyday ad channel before anyone else can. For publishers, that’s another buyer of attention you used to monetize — and another reason your content’s value to AI should be priced, not given away.
