# Polymarket Spread Sniper
> **This is a template.** Buys the underpriced side when the CLOB midpoint diverges from the AMM price. No outcome prediction needed — pure spread arbitrage.
## The Edge
Polymarket has two pricing mechanisms:
1. **AMM** — pool-based price, slow to update
2. **CLOB** — live orderbook, reflects real money
When they diverge by >4%, the AMM is mispriced. This skill buys the cheap side and profits when prices converge.
