We reverse-engineered ChatGPT's Shopping trigger. Here's how it works.
ChatGPT Shopping is driven far more by product category than by purchase intent language. In our analysis of 1.18 million prompts and a 7,500-prompt labeled sample, prompts naming shippable consumer goods were much more likely to trigger Shopping cards, while software, services, travel, and financial products almost never did. Adding 1–2 concrete constraints like price, features, or use case increased trigger probability, but only within product categories. The clearest rule was simple: if the prompt’s main noun is something you could buy on Amazon, Shopping is likely to appear. Using that logic, we built a classifier that reproduced ChatGPT’s Shopping behavior with about 95–97% accuracy.
