PredictionBubbles’ live board covers 2,145 open markets across Kalshi and Polymarket, with total traded volume of 6.65 billion dollars, according to PredictionBubbles.
The figures were reported on Nov 3, 2026, at 9:45 AM ET. They describe the markets tracked by the board, rather than a breakdown of activity on each platform.
Politics leads the tracked categories
Politics accounts for 1,102 open markets and 5.24 billion dollars in traded volume, according to PredictionBubbles. It leads the reported categories in both market count and trading volume.
Sports follows with 493 markets and 758.5 million dollars traded. Crypto accounts for 240 markets and 240.6 million dollars in volume.
What it means for prediction markets
- Politics represents the largest concentration of markets and traded volume in the reported category figures.
- Sports exceeds crypto in both open-market count and traded volume on the board.
- The supplied figures do not separate Kalshi from Polymarket or provide individual contract prices, so they do not establish platform-level activity or implied probabilities for particular outcomes.
