Kalshi’s contract on Republicans winning the House in 2026 was priced at 9.5%, up 0.7 percentage points, with $47.4M traded at the Oct 24, 2026 · 9:39 PM ET snapshot. The price indicates that traders still assigned a low probability to the outcome despite the increase.
According to PredictionBubbles, its politics board places the House-control contract among its most-traded political markets. The dashboard reports probability changes over the preceding 24 hours, while its volume rankings measure cumulative trading rather than the size of a price move.
Volume and probability tell different stories
The House contract sits in the board’s political/election category, separate from its leading market. According to PredictionBubbles, the most-traded politics contract at the latest refresh concerned whether the U.S. would invade Iran before 2027, with $75.3M traded on Polymarket.
PredictionBubbles tracks 935 open politics markets, including 215 from Kalshi and 720 from Polymarket. Its embedded visualization displays the 300 largest by volume, while the full board covers all 935. The data updates every 15 minutes, although trading on the underlying venues continues between refreshes.
The supplied material does not identify a news event behind the House contract’s increase. PredictionBubbles describes its service as a dashboard of market prices rather than an independent forecast, and cautions that trader consensus can be wrong.
What it means for prediction markets
A rise from a low base: The 0.7-point increase leaves Republican House control priced at 9.5%; it represents a modest shift, not a reversal in the market’s assessment.
Activity is not certainty: The $47.4M traded establishes substantial cumulative activity, but volume alone does not demonstrate forecast accuracy.
Refresh timing matters: PredictionBubbles updates every 15 minutes, so its displayed probability may differ from a venue’s latest traded price.
Compare contract terms carefully: PredictionBubbles notes that related Kalshi and Polymarket questions can differ in wording and resolution rules.
