PredictionToolkit
What is PredictionBell?
Sports Edge Finder groups matchups and highlights price differences between Polymarket and Kalshi. Coverage includes tennis, soccer, baseball, basketball, football, hockey, combat sports, esports and cricket. Find an event, compare the displayed outcome prices and follow the venue links to examine the actual contracts.
Market Pulse covers 6 groups: equities, crypto, interest rates, macro, earnings and volatility. Its 6-hour probability changes help identify repricing for further research, including a pre-market review. PredictionBell is a read-only screener rather than an order-entry terminal. Homepage examples are explicitly illustrative; current data belongs in the dashboard. A gap can reflect different rules, spreads or available size rather than a tradable opportunity.
