What is Polymarket-Sports-Arbitrage-Bot?

This TypeScript CLI bot pulls live sports markets from Polymarket's Gamma API, matches them to Odds API or ESPN events, and flags directional arbitrage opportunities where sportsbook-implied probabilities exceed Polymarket prices. It runs paper-mode auto-trading cycles with configurable stakes, stop-losses, take-profits, and liquidity checks, dumping logs and summaries to JSON/CSV for backtesting. Built for Polymarket arbitrage sports betting, it handles NBA, NFL, MLB via simple `npm start` or granular commands like `npm run fetch:odds-comparison`.

Why is it gaining traction?

Event matching scores confidence levels, ESPN fallback dodges Odds API delays or keys, and sample backtests claim +44% returns over 30 days on $25 stakes. CLI hooks like `npm run detect:arb` and session summaries make spotting Polymarket sports arbitrage bot edges instant, no quant PhD needed. Devs grab it as a Polymarket github bot starter for sports API websocket tweaks or CLOB cloning.

Who should use this?

Quant hobbyists or sports bettors automating Polymarket sports bets against books, especially NBA/MLB traders chasing reddit-hyped edges. Devs forking for Polymarket github sdk agents or custom arbitrage sports betting bots. Avoid if you need live execution or non-US sports accuracy.

Verdict

Grab for paper-testing Polymarket sports arbitrage—CLI shines, docs solid, but 10 stars and 0.9% credibility score mean it's raw; add tests and live Polymarket github api trades yourself.
