TL;DR

Twitter thread reverse-engineering a Polymarket account that quietly turned $50 into $435,000 — then using a single Claude prompt to build a similar arbitrage bot in 40 minutes. The edge: Polymarket updated BTC contract prices slower than real-time price feeds, creating a systematic arb window.
