Amazon Partners with OpenAI to Enable Advertisers to Place Ads on ChatGPT
nashnova research
Amazon announced a partnership with OpenAI allowing its advertisers to extend campaigns into ChatGPT, starting with select U.S. brands. The world's largest retailer just endorsed AI chat as an ad channel — putting direct pressure on Google and Meta's search-and-social dominance.
What does this partnership actually do?
Amazon lets brands that advertise on its platform run the same ads inside ChatGPT. The format is text or image, displayed below ChatGPT's responses.
The division of labor is clear: Amazon handles campaign setup and management; OpenAI's ad system makes all placement decisions.
In plain terms = Amazon supplies the brand clients, OpenAI supplies the traffic and the targeting algorithm. Each side runs its own piece.
Why is Amazon reversing course?
Amazon previously took a restrictive stance toward ChatGPT, Claude, Gemini, and other AI platforms accessing its e-commerce data, while investing heavily in its own AI shopping tools.
Yet Sensor Tower data shows that between April and August this year, Amazon quietly became the largest retail advertiser on ChatGPT.
This means → Amazon's own media-buying team validated the channel first. The formal partnership turns an internal purchasing strategy into an open platform — from "buying quietly for ourselves" to "letting all our advertisers buy."
How big is ChatGPT's ad business already?
OpenAI's ad business has hit an annualized revenue run rate of $1 billion. ChatGPT's weekly active users now stand at 900 million.
OpenAI began testing ChatGPT ads in the U.S. in February, with early partners including Best Buy and Williams-Sonoma.
This reflects a shift: ChatGPT is no longer just a chat tool — it is rapidly becoming an ad monetization platform, faster than most observers expected.
What does this mean for Google and Meta?
With Amazon's advertiser base now feeding in, ChatGPT's ad inventory grows in both scale and quality, widening OpenAI's monetization path.
Amazon's announcement called conversational ads inside AI chatbots "the fastest-growing engagement opportunity" for brands to reach customers.
This means → ad budgets are shifting from search and social toward AI-conversation contexts. For Google, Meta, and others built on search-and-social ad revenue, this is a structural competitive pressure.
