OpenAI said on September 16 that it is testing AI-driven advertising formats, among them a product called Sponsored Agents, alongside integrations with HubSpot and Shopify S¹. The company that built its brand on subscriptions is now building an ad business, at the same moment Google embeds Gemini into Search ads P⁵.
The move extends a ChatGPT ads pilot that OpenAI began widening in May 2026, when it added new ways for advertisers to buy and manage campaigns while keeping them "clearly separate from ChatGPT's answers" P³. Sponsored Agents and marketing tools, plus the HubSpot and Shopify connections, form the next layer on top of that pilot S¹.
My read: This is the first time I've seen OpenAI use the phrase "Sponsored Agents," and the name tells you more than the announcement does. If an agent is an AI that takes actions on a user's behalf, a sponsored agent is one a brand pays to place in that workflow. I don't buy the word "explore" here. You don't name HubSpot and Shopify integrations unless you're building toward a product. What I'd watch is whether Sponsored Agents appear inside ChatGPT itself or only on third-party surfaces, because that determines whether users experience them as answers or as ads.
The post leaves key mechanics undefined
OpenAI's announcement, published on its news page, sketches the advertising experiences in broad strokes: Sponsored Agents, tools for marketers, and the two platform integrations S¹. It offers no technical details on what a Sponsored Agent is, how it functions, or where users would encounter one — no architecture, no released code, and no availability dates have been published, so the format remains unverified beyond OpenAI's own description. The word "explore" appears in the announcement, which is softer than "launch" or "roll out" S¹.
No independent outlet has reported original details beyond OpenAI's own post. The only secondary source is a Google News RSS snippet that repeats the same announcement S². The HubSpot and Shopify integrations may not be live yet; the announcement does not specify availability dates.
Google's Gemini ad tests point to a converging market
On May 20, 2026, Google announced it was testing new ad formats in Search built with Gemini. The expansion of a Direct Offers pilot connects brands with consumers researching complex topics P⁵. Both companies are converging on the same idea: as AI mediates more of how people find products, the ad unit shifts from a clickable link to an AI-generated response.
OpenAI's openai-agents-python framework on GitHub was last updated August 28, 2026. It gives developers a way to build multi-agent workflows P⁴. That framework could be the technical substrate Sponsored Agents run on, though OpenAI has not said so — the connection is speculative and unconfirmed.
Shopify merchants and HubSpot marketers sit closest to the pilot
A Shopify merchant running product campaigns or a B2B marketer using HubSpot for lead nurturing would be the natural first testers of these tools, if and when they become available. For a merchant already buying ChatGPT ad placements through the May pilot, adding a Sponsored Agent would mean managing a new creative format alongside existing campaign-buying tools P³. For now, the live surface remains the ChatGPT ads pilot that OpenAI expanded in May P³. OpenAI has not announced a launch date for Sponsored Agents or the integrations.
