ChatGPT can now buy things for you. Google just released a protocol for AI agents to handle payments. And nobody's asking the obvious question: who's advertising to your AI? OpenAI's Instant Checkout lets you shop without leaving the chat. Google's Agent Payments Protocol (AP2) gives AI agents the infrastructure to transact on your behalf. Both companies insist results are "organic" and "unsponsored." Right. Because when you build a payment rail that processes transactions through conversational AI, advertisers definitely won't figure out how to optimize their product descriptions for agent preferences instead of human eyeballs. We spent decades learning how to game Google's algorithm. How to buy Facebook ads that target your exact neuroses. How to SEO our way into your search results. Now we're handing purchase decisions to agents that "consider factors like availability, price, quality" and trust them to rank options "purely on relevance." Relevance to what? The prompt you typed? The preferences they've inferred? The merchants who've optimized their listings for whatever embedding space these models operate in? The shift isn't humans buying things versus AI buying things. It's discoverable persuasion versus invisible influence. At least when you see an ad, you know someone paid to change your mind. When your agent "recommends" something, you'll assume it's acting in your interest.
