Prediction markets put Democrats above 90 percent for House control
Ahead of the November 3 midterms, Kalshi lists Democratic control of the House at 93 percent while Polymarket shows 94 percent with about 31 million dollars traded on the market.
Democrats are strongly favored to control the House ahead of the November 3 midterms, according to Covers. Kalshi puts the probability at 93 percent, while Polymarket shows 94 percent.
Two platforms show similar expectations
The figures, reported on Oct 31, 2026 at 8:45 PM ET, place the two platforms just one percentage point apart. Both indicate a substantial market preference for Democratic House control, rather than certainty about the outcome.
Covers also cites about 31 million dollars traded on the market alongside the Polymarket probability. That figure measures trading activity, not the likelihood of the result.
A snapshot before the vote
The supplied summary provides a pre-election snapshot but no earlier prices for comparison. It therefore does not establish whether expectations for Democratic control have strengthened, weakened or remained steady.
What it means for prediction markets
- Close alignment: Kalshi’s 93 percent and Polymarket’s 94 percent readings show similar expectations across the two platforms.
- Residual uncertainty: Neither price treats Democratic House control as guaranteed ahead of November 3.
- Limited trend evidence: About 31 million dollars in trading accompanies the reported market snapshot, but the summary supplies no price history from which to assess momentum.
