Democratic House seat estimate slips while control odds remain steady
Polyguana puts expected Democratic House seats at 247.8 against 163.9 for Republicans in the late read, down from 253.6 in the 11:15 p.m. ET read, while House control holds at 99 percent on both Polymarket and Kalshi with 60.2 million dollars traded.
According to Polyguana’s Nov 3, 2026 · 11:30 PM ET update, expected Democratic House seats stood at 247.8 in the late live-board reading, compared with 163.9 for Republicans.
The Democratic estimate was down from 253.6 at 11:15 p.m. ET. The lower reading narrowed the party’s projected seat total without changing the reported market probability of House control.
Seat expectations and control odds diverge
According to Polyguana, Democratic House-control odds remained at 99 percent on both Polymarket and Kalshi. The update reported 60.2 million dollars traded.
The readings describe different outcomes: expected seats measure the anticipated size of a party’s delegation, while control odds address which party wins the chamber. In this update, a lower Democratic seat estimate coexisted with unchanged control pricing.
What it means for prediction markets
- Seat totals moved: The Democratic expectation fell from 253.6 to 247.8 between the 11:15 p.m. ET reading and the late update.
- Control pricing held: Polymarket and Kalshi both remained at 99 percent for Democratic House control.
- The distinction matters: The update signals a revision to expected Democratic strength, not a reported shift in the probability of controlling the chamber.
