The challenge

The client wanted to earn from Polymarket's order books but couldn't manually watch hundreds of markets or react fast enough to mispricings and complementary-outcome arbitrage.

What we built

We built a Python engine on Polymarket's CLOB API scanning 100+ markets for complementary-outcome arbitrage and stale quotes, market-making selected books, with position limits and resolution-aware exits. Everything is monitored from a Telegram dashboard.
