What is Polymarket-Arbitrage-Trading-Bot?

This TypeScript bot automates arbitrage trading on Polymarket's short-duration Up/Down prediction markets, using real-time WebSocket orderbook data to predict price moves and place limit orders on both sides for spread capture. It handles configurable markets like BTC or ETH, position sizing, risk limits, and hedges, solving the manual hassle of scanning polymarket arbitrage opportunities in crypto betting. Users get a ready-to-run npm start command plus dedicated redeem scripts for settling winnings via Polygon USDC.

Why is it gaining traction?

It stands out with adaptive price prediction that only trades high-confidence signals, real-time Polymarket CLOB integration via GitHub websocket, and built-in tools like auto-redeem scanners—far beyond basic polymarket arbitrage calculators or reddit-shared scripts. The .env-driven config for shares per side, tick sizes, and max buys per market makes tweaking strategies dead simple, hooking devs tired of cobbling together Polymarket GitHub API clobs or Python/Rust clones.

Who should use this?

Crypto traders automating polymarket arbitrage betting on volatile assets like BTC/ETH, or quant devs building polymarket arbitrage finders/scanners for CLOB-based tools. Ideal for those with a funded Polygon wallet eyeing passive arb in short 15-minute markets, not manual reddit hunters.

Verdict

Grab it if you're experimenting with Polymarket GitHub bots—solid docs and CLI redeemers make it approachable despite 86 stars and experimental status. Low 0.7% credibility score flags risks like unproven profitability; test small on testnet first.
