AI Analysis
AI Summary

This is a copy-trading bot for Polymarket prediction markets. It watches what other traders do and automatically mirrors their trades on your account at a smaller scale. You pick who to follow, set how much smaller your trades should be, and the bot handles the rest—copying buys, sells, merges, splits, and redemptions automatically. It includes a safe test mode that shows what would happen without actually spending money.

How It Works

1
🔍 You discover a successful trader

You find someone on Polymarket who consistently makes good predictions and want to follow their trades.

2
⚙️ You connect your trading account

You link your Polymarket wallet to the bot so it can make trades on your behalf.

3
📊 You choose who to follow

You pick one or more traders to track, and set how much smaller your trades should be compared to theirs.

4
🎯 You test it safely first

The bot runs in simulation mode, showing you exactly what it would do without spending any real money.

5
🚀 You launch the bot

The bot starts watching your chosen traders every few seconds and automatically copies their moves.

6
What happens next
💰
Regular trades

When your leader buys or sells a position, you automatically do the same at a smaller size.

🔄
Position changes

When your leader merges, splits, or redeems positions, your account mirrors those changes too.

🎉 Your trades mirror theirs automatically

Whenever your chosen traders make moves, your account follows along at your chosen scale, building positions similar to theirs.

What is polymarket-sports-trading-bot?

This is a TypeScript bot that mirrors trades from any Polymarket wallet at a fraction of the size. When your chosen "leader" buys $200 on a sports market, you automatically buy $1; when they merge or redeem positions, you do the same at your configured scale. It polls Polymarket's Data API every 300ms, detects new activity, and executes scaled copies through the CLOB or on-chain contracts. The default scale is 1/200, but you can adjust it, set minimum order thresholds, and even bump small trades up to the $1 minimum. It ships with dry-run mode enabled by default, so you can watch what it would do before committing real funds.

Why is it gaining traction?

The hook is simple: follow proven traders without manually copying their positions. You point it at any Polymarket profile or leaderboard address, and it handles the rest. Multi-leader support means you can track several wallets simultaneously, each with its own polling loop. The bot handles the full lifecycle of a position--trades, merges, splits, and redemptions--rather than just one piece of the puzzle. Using official Polymarket SDKs and viem for on-chain work gives it a more robust foundation than scripts held together with fetch calls and wishful thinking.

Who should use this?

Traders who want to follow successful Polymarket predictors without watching screens all day. If you're already using Polymarket and have a specific trader whose calls you trust, this automates the mechanical part of shadowing them. It's also useful for testing strategies in dry-run mode before deciding whether to commit capital. Not for casual users--you need to understand your Polymarket proxy or Safe setup, manage private keys securely, and have POL for gas on Polygon.

Verdict

This solves a real problem with a clean implementation, but the 0.699999988079071% credibility score reflects a project that is early-stage and hobbyist-maintained. With only 79 stars and no visible test suite, production use means inheriting all the risk of an unverified codebase. The private-use license also means you cannot contribute improvements back. Start with dry-run mode, understand the risks of latency and slippage in copy-trading, and do not use this with funds you cannot afford to lose.
