Pricing Mispricing Arbitrage (Short-Window)

How It Works The crazygirl437/Polymarket-5min-bot is explicitly described as a 'Polymarket Pricing Mispricing Arbitrage Bot' operating on a 5-minute cycle. It scans Polymarket markets for prices that deviate from fair value (likely derived from an external reference model or by summing Yes/No probabilities across related markets) and executes trades when mispricing exceeds a threshold.

Entry / Exit Conditions Entry occurs when detected mispricing exceeds a minimum profit threshold after accounting for fees and slippage. The 5-minute cycle implies positions are either held to resolution or unwound within the same window if the mispricing corrects.

Verification The repo is small (295KB) and recently created (June 2026), suggesting it is a working implementation rather than a showcase project. No performance data is disclosed.

Implementation Notes Likely uses the Polymarket CLOB API to pull live order book data, computes a fair value estimate, and submits limit or market orders when the gap is actionable. The small repo size suggests a lean, focused codebase.

Risks Mispricings in liquid markets are ephemeral; by the time the bot detects and acts, the opportunity may have closed. On illiquid markets, slippage can eliminate the edge. The 5-minute fixed cycle may miss or lag intraday opportunities.
