OpenAI spent the spring tearing down the wall around ChatGPT ads: a $200K beta minimum became $50K in April and was removed entirely in May, so any US advertiser can now buy into a product reaching 900M+ people a week, where roughly one in five queries has commercial intent. But an open ad auction is won by the deepest pocket, which is the one fight a pre-seed founder can’t win. The asymmetric move is one line up the screen: be the product ChatGPT recommends in the answer, not the sponsored link beneath it. That layer, generative engine optimization plus the new agentic-commerce rails (Agentic Commerce Protocol, Shopify Agentic Storefronts), is cheap and gameable right now the way SEO was in 2010, with tools starting around $39/month against the old $50K ad floor. The catch: it will get gamed out and the labs may eventually sell the recommendation slot too, so treat it as an early edge, not a forever channel.
