What is polymarket-sport-trading-bot?

This is a TypeScript bot that mirrors trades from any Polymarket wallet onto your own account at a configurable scale. When a leader trader buys $200 in a market, you automatically buy $1 (assuming the default 1/200 divisor). The bot polls Polymarket's activity API every 300ms and replicates not just trades, but also merges, splits, and redemptions using the official Polymarket SDKs and viem for on-chain interactions.

Why is it gaining traction?

Copy-trading is the killer feature. Instead of building your own prediction market strategy, you can follow proven traders and scale their moves down to your risk tolerance. The dry-run mode by default means you can test the bot safely before committing real funds. Supporting multiple leader wallets in parallel lets you diversify across different traders without managing separate instances.

Who should use this?

If you're already on Polymarket and have identified traders you trust, this automates the manual work of following their positions. Sports bettors who track sharp players can mirror them without constant monitoring. Developers building trading tools will find this useful as a reference implementation for the Polymarket CLOB API and on-chain position management.

Verdict

The concept is solid and the implementation is functional, but with 78 stars and a 0.7% credibility score, this is an early-stage project with minimal community validation. Test thoroughly with dry-run enabled before going live, and be aware that latency in the polling loop means you will experience slippage on fast-moving markets. Worth trying if you want to experiment with copy-trading on Polymarket, but do not treat it as production-ready without your own due diligence.
