What is polymarket-trading-bot?

This is a TypeScript-based copy trading bot for Polymarket. You point it at any trader's wallet address or username, and it mirrors their trades to your own account on a configurable schedule. It polls Polymarket's data API for activity, then places limit orders through the CLOB with your own sizing rules. The bot handles username resolution, tick size rounding, and order sizing limits out of the box. It is not arbitrage or market-making -- it follows the leader with a configurable multiplier and hard caps so you do not accidentally overexpose.

Why is it gaining traction?

Copy trading is a proven pattern from TradFi, and bringing it to Polymarket's prediction markets fills a real gap. The bot is straightforward to deploy: set a few environment variables, point it at a target, and watch it run. The README is unusually careful about risk warnings and safe defaults, which signals the author understands that auto-trading with real money requires guardrails. The configuration supports both raw wallet addresses and Polymarket usernames, which makes targeting popular traders practical without needing block explorers.

Who should use this?

Traders who want to follow successful Polymarket predictors without monitoring feeds manually. Researchers testing whether copy trading strategies are profitable on prediction markets. Developers building automated trading workflows who need a reference implementation for Polymarket's CLOB and data APIs. Not suitable for anyone expecting low-latency execution -- this is poll-based by design.

Verdict

This is a functional, documented copy trading bot with a clear purpose and reasonable safety defaults. The credibility score of 0.7% reflects the reality: 69 stars, limited test coverage, and a single-author repo. It works for experimentation and learning, but treat it as a starting point, not production infrastructure. Run with small multipliers and small caps until you trust the behavior.
