Install → your agent gets $10,000 paper money → trades real Polymarket order books → tracks P&L → competes on a public leaderboard. Zero risk. Real prices. \"My AI agent hit +18% ROI on Polymarket in one week. Zero risk, real order books.\" Part of agent-next — open research lab for self-evolving autonomous agents. 60-second demo That's it. Your AI agent is now trading Polymarket with zero risk. Install Requires Python 3.10+. Not a toy — this is a real exchange simulator Other tools mock prices or use random numbers. We simulate the actual exchange: - Level-by-level order book execution — your order walks the real Polymarket ask/bid book, consuming liquidity at each price level, just like a real trade - Exact fee model — bps/10000 × min(price, 1-price) × shares — the same formula Polymarket uses - Slippage tracking — every trade records how much worse your fill was vs the midpoint, in basis points - Limit order state machine — GTC (good-til-cancelled) and GTD (good-til-date) with full lifecycle - Strategy backtesting — replay your strategy against historical price snapshots - Multi-outcome markets — not just YES/NO binary, supports any number of outcomes Your paper P&L would match real P&L within the spread. That's the point.
