AdGPT or MadGPT?
OpenAI ad partner now selling ChatGPT ad placements based on "prompt relevance"
ChatGPT ads spark privacy panic, partnership doubts, and meme-fueled chaos
TLDR: StackAdapt is courting brands to run “prompt-relevant” ads in ChatGPT with a $50K pilot, stirring fears that chats could influence targeting. Commenters split between privacy panic, doubts the partnership is real, and weary acceptance—while many demand paid users be spared as AI assistants inch toward ad-driven future.
StackAdapt is quietly pitching advertisers on ads inside ChatGPT, priced $15–$60 per thousand views with a $50,000 minimum, and targeted by “prompt relevance”—basically showing you ads while you’re researching products in chat, per a deck reviewed by ADWEEK. The pitch calls it a new “discovery layer” and even claims a partnership with OpenAI, though this is framed as a limited pilot and early test.
The internet? Immediately on fire. Privacy hawks read “prompt relevance” as “prompt peeking,” with one stunned commenter recalling earlier assurances and asking, “how is that not securities fraud?” Another turned it into a dev-meme roast: when engineers say no to shady features, the AI assistant says yes—“Claude Code: completed.” Skeptics aren’t convinced the inventory is even locked: one buyer type wondered if StackAdapt is just testing demand and begged to keep ads out of paid ChatGPT. Meanwhile, the cynics shrugged: the only shocking part is that it took this long.
There’s also black-comedy energy about OpenAI’s “Rapid Unintentional Disassembly” of its original vision, as marketers salivate over a shiny new ad aisle inside your chatbot. End result: a noisy three-way slugfest—privacy alarms vs. ad-tech skeptics vs. resigned realists—while brands eye the pilot’s $15 CPM bait and users ask what, exactly, gets used to target them.
