Extropy builds representative synthetic populations and simulates how they react to real-world events. Every agent reasons individually from their own finances, job, commute, politics, and social network. We just published two studies: simulating Americans through a US-Iran war, and predicting the 2026 House midterms benchmarked against Kalshi. Open source. Define a scenario, build a population, run the simulation.
