Kalshi election combinations draw $126 million as House odds hit yearly peak
Action Network reports trading volume for House and Senate control on Kalshi now exceeds 416 million dollars, and election combo contracts that price how individual race results affect each other have taken off with 126 million dollars traded, while Kalshi House traders put Democrats at 93.7 percent, the highest reading of the year.
Kalshi’s markets for control of the House and Senate have drawn more than $416 million in trading volume, according to Action Network. The figures were reported on Nov 3, 2026, at 4:45 PM ET.
Combined outcomes attract trading
Election combo contracts have recorded $126 million in trading volume, according to Action Network. These contracts price relationships between individual race results, rather than treating each outcome separately.
That structure brings the connection between a Senate race and control of Congress into focus. For prediction-market readers, the distinction is between pricing an individual result and pricing how that result relates to other election outcomes.
Democratic House probability reaches annual high
Kalshi’s House-control traders put Democrats at 93.7 percent, according to Action Network—the highest reading of the year.
The reported figures capture two different measures: trading volume in congressional-control and combination contracts, and the market-implied probability of Democratic House control. The volume totals do not themselves indicate which outcome traders consider most likely.
What it means for prediction markets
- Linked results are drawing activity: The $126 million traded in combo contracts highlights interest in relationships between election outcomes.
- House pricing is strongly tilted: The 93.7 percent Democratic reading marks a yearly high, not a guaranteed result.
- Volume and probability serve different purposes: More than $416 million in House- and Senate-control trading measures activity; the House probability measures the market’s assessment of that outcome.
