Polymarket trading bot for prediction markets — CLOB order book, edge detection and arbitrage signals in your terminal.
Browse CLOB markets · watch the book · run probability-edge & liquidity strategies · track USDC.
Polymarket Prediction Bot is a Polymarket trading bot for prediction markets — a keyboard-driven terminal dashboard for Polymarket, the Polygon-based prediction market with a central-limit order book (CLOB) and USDC settlement. It bundles a markets browser, a live CLOB order-book view, a strategy engine and a position/fill tracker into one pane — a complete Polymarket CLOB API client (REST + WebSocket) in your terminal.
Polymarket shares resolve YES/NO to $1/$0 on real events: elections, crypto milestones, sports, macro prints. Pricing a share is pricing a probability — the bot runs edge detection and liquidity provision strategies against a fair-probability model, surfaces cross-market arbitrage signals (YES+NO spread, multi-outcome), and keeps position tracking and PnL history with risk limits and exposure controls. A paper trading mode with virtual USDC balance lets you iterate safely. Terminal UI built with Textual and Rich — an educational open-source toolkit, no financial advice.
⚠️ Paper-trade by default.
--demosimulates fills against a bundled dataset. Live order placement requires your own Polymarket API credentials and is gated behind explicit configuration.

Built-in strategies (selectable, composable):
- Probability-edge — compares market price to a fair-probability model and signals when the edge exceeds a threshold.
- Book-imbalance — large YES/NO size skew as a directional cue.
- Liquidity — wide-spread mean-reversion toward mid.
Each signal carries a confidence 0..1 and a suggested side. The bot logs every signal; in
live mode you wire a strategy to an order template.
