Market Diagnostics Tool
This tool provides data for market analysis and educational purposes only. It is not trading, investment, financial, or wagering advice.
Market signals and probability differences are diagnostic inputs only. Actual execution can differ because of fees, slippage, liquidity, market access, data delay, and settlement rule differences.
Method Notes
Polymarket share prices are already probabilities. They are not transformed with an odds formula.
Kelly sizing requires your own probability estimate. Implied probability is not used as the model input.
