Amazon Advertisers Can Run Campaigns in ChatGPT

Under the arrangement, Amazon will build and manage campaigns, while OpenAI’s ad system will decide where and how they appear inside ChatGPT, in text or image form below chatbot responses. The rollout starts with a limited group of U.S. brands, suggesting both sides are still testing how users respond to commerce-linked ads inside an AI assistant.

For Amazon, the deal is as much defensive as it is opportunistic. The company has been tightening access for rival AI assistants such as ChatGPT, Claude and Gemini on its shopping platform while building its own AI shopping tools. At the same time, it has been buying ad inventory inside ChatGPT for months and, according to Sensor Tower, became the largest retailer advertiser on the platform between April and August. That tells investors Amazon sees value in OpenAI’s traffic even as it works to keep that traffic from becoming a direct threat to its marketplace.

For OpenAI, the partnership is another proof point that ChatGPT is evolving from a conversational tool into an advertising and marketing venue. That transition could become important for the economics of the AI sector: large language models are expensive to train and run, and ad monetization offers a path to offset those costs without leaning entirely on subscriptions or enterprise sales. The bull case is that conversational ads could command high-intent spending and attractive conversion rates. The bear case is that intrusive placement could weaken the user experience and slow engagement if ads feel too aggressive.

Investors should also read the deal as a sign of where competition is heading. Amazon, Meta, Google and Microsoft are all racing to define how AI will be monetized, and the winners may be the companies that control both demand and distribution. Amazon’s advertising business already benefits from shoppers close to purchase, and extending that model into ChatGPT could widen its reach beyond its own platform if consumers increasingly start product discovery in AI assistants.

The near-term question is whether users accept ads in ChatGPT as relevant recommendations or reject them as clutter. If the format works, OpenAI gains a new revenue engine and Amazon gets another high-value ad channel. If it does not, the deal may still matter as an early indicator that the fight over AI monetization is shifting from model quality to commercial placement.
