Prediction markets recorded 6.0 billion dollars in trading over the last 24 hours across nine exchanges, according to DeFi Rate. The reported total counts contracts at 1 dollar each.
The figures offer a snapshot of aggregate activity alongside a weekly shift in pricing for Democratic control of the Senate. They do not provide an exchange-by-exchange breakdown.
Senate pricing moves toward Democrats
DeFi Rate’s November 1 snapshot, taken at 9:50 PM ET, put Democratic Senate control at about 71 percent across Kalshi and Polymarket. That was up 6 points on the week.
The report was published on Nov 1, 2026, at 10:15 PM ET. The nine-exchange trading total and the Senate pricing across Kalshi and Polymarket cover different scopes; the supplied figures do not identify how much turnover came from Senate contracts.
What it means for prediction markets
- Counting method matters: The 6.0 billion dollars in reported activity uses a value of 1 dollar per contract, a convention readers should retain when comparing volume figures.
- The Senate move is weekly: Democratic control stood at about 71 percent, up 6 points on the week—not necessarily over the 24-hour trading window.
- Aggregate volume does not establish contract-level activity: The snapshot does not show how trading was distributed among the nine exchanges or how much was tied to Senate control.
