What is PredictBack?
PredictBack is a quantitative backtesting and research platform for prediction markets, starting with Polymarket. Most participants approach prediction markets by taking a directional opinion: Yes or No, long or short, belief or disbelief. PredictBack is built to push beyond that. We help users test rule-based, automated trading strategies across many markets, time periods, and regimes—so you can understand how your logic behaves in aggregate, not just in a single conviction trade.
Why PredictBack Exists
Backtesting is the scientific method of trading:
You formalize a hypothesis (your strategy)
You test it on historical data
You control for confounders like fees, liquidity, and execution
Only then do you consider live deployment
In traditional markets, traders rely on mature tooling (Backtrader, LEAN, MultiCharts, etc.) to do this rigorously. Prediction markets, despite growing rapidly, lack comparable research infrastructure. PredictBack fills that gap.
