Cross-market arbitrage scanner — Polymarket × Kalshi.
Problem
Polymarket and Kalshi list the same events but rarely price them the same. The spread closes in minutes, and watching hundreds of markets at once isn't a human job.
Approach
A scanner that pairs contracts across both exchanges using FAISS for cheap recall, then a Claude pass for semantic confirmation. Spreads are fee-adjusted, ranked, and tracked through to settlement.
Result
Live, running 24/7. 481 opportunities detected; scoreboard tracks post-fee, post-resolution P&L — not paper gains.
