Prediction markets are becoming financial data, but a 63% price does not always mean 63% odds
PredictionBubbles is a dashboard that lets users scan prediction markets like Polymarket and Kalshi on one screen by turning tradable questions into bubbles sized and filtered by measures such as open interest, volume, probability, category, platform, and expiry. It acts like a screener or heat map for prediction markets, making market discovery easier than browsing individual contracts. The broader market is moving toward data distribution and analytics: ProCap Financial said Kalshi Research would supply real-time figures to ProCap Insights, while Polymarket already offers public discovery, analytics, order-book, pricing, and WebSocket feeds plus a builder program. Kalshi has also highlighted rising institutional activity and launched Kalshi Pro for power users. Research cited in the piece suggests prediction-market prices are useful but context-dependent and sometimes miscalibrated, especially near contract close or in more complex trades. The main takeaway is that competition is shifting from listing questions to organizing, distributing, and interpreting large volumes of tradable forecasts.
