PolymarketCopycatWhaleScanner

The anthonyonazure/polymarket-copycat repository implements a copy-trading strategy focused on whale wallets. It scans Polymarket for large trades (whales) by monitoring on-chain activity and/or the CLOB API. When a whale makes a significant trade, the bot simulates (paper-trades) the same trade to track performance. A live dashboard displays current positions, PnL, and whale activity.

The edge source is the assumption that certain whale wallets have persistent alpha — either through superior information, faster reaction times, or better models. By copying their trades, the bot aims to piggyback on that edge. The scanner likely ranks whales by historical PnL, win rate, and consistency, then follows the top performers. Entry occurs when a followed whale enters a position; exit occurs when the whale exits or after a fixed holding period.

Implementation: TypeScript, 45KB (small), created March 2026, updated September 15, 2026. The small size suggests it is a lightweight tool, possibly using Polymarket's public API to track trades. The paper-trading mode means no live capital is at risk, making it a simulation and research tool. The dashboard provides visual feedback on performance.

Risks: Copy-trading whales is subject to latency (you see the trade after it happens, often at a worse price). Whales may have different risk tolerances, time horizons, or capital constraints. Some whales may be lucky rather than skilled. The small codebase may lack robust error handling. No live execution means real-world slippage is not accounted for.

Verified results: No public PnL data. The repository has 0 stars and 0 forks. The strategy is a common approach in prediction markets, but without live trading or backtest results, its effectiveness is unproven.
