What is polymarket-kalshi-arbitrage-bot?

This TypeScript bot scans short-duration prediction markets on Polymarket and Kalshi, hunting arbitrage by comparing Kalshi YES prices against Polymarket UP tokens via the polymarket github clob and trade API. It signals buys when spreads hit 10+ cents in a 93-96¢ confidence band or spots late resolution gaps, then auto-places orders using the official polymarket clob-client if you supply wallet creds. Deploy it as an Express server on a VPS for polling, /status checks, and optional automated trading with cooldowns—all configurable via .env.

Why is it gaining traction?

With 62 stars, it hooks devs via dead-simple setup for polymarket trading bot github workflows, a live /status API exposing signals/reasons without trading risk, and proven Reddit demos of kalshi-polymarket arb plays. Unlike broad bots, it nails 15-minute events with start delays, liquidity checks, and proxy wallet execution, skipping fluff for fast iteration on polymarket trading strategies.

Who should use this?

Prediction market quants automating polymarket kalshi arbitrage bot reddit or btc setups on Polygon. Devs prototyping polymarket github api bots, websocket alternatives via polling, or kalshi-polymarket value bets before scaling to Python/Rust clones. Suits VPS runners chasing low-risk edges in high-confidence spreads.

Verdict

Grab it for polished docs and quick polymarket trading api integration, but its 0.9% credibility score and modest 62 stars mean paper-trade first—mature enough for signals, greenfield for heavy live use. Fork if prediction arb is your edge.
