Anthropic just told every founder where to build.

Where? In a research report sitting on their own website: 37,657 real conversations, the actual questions people bring to Claude when they need to decide something in their life, sorted into nine verticals with real percentages and real sub-clusters attached.

Everyone read it as an AI safety story. It’s a market map.

This is the closest thing to free customer discovery you will ever get from a company that isn’t yours. Nine verticals, ranked by volume, stakes and how often the model gets it wrong, each one telling you exactly what a stranger typed into a chat box because there was nowhere else to ask.

👇 Below is the full breakdown, plus the potential businesses sitting inside each one
