Background
Wisconsin's 3rd Congressional District, in the western part of the state, is being decided in the November 2026 general election, with the market listing a resolution date of Nov. 5, 2026. Republican Rep. Derrick Van Orden is seeking another term against Democrat Rebecca Cooke, who won her August 11 primary. Van Orden beat Cooke in 2024 by just under 3 points. The seat is on the DCCC's Red to Blue list, and spending in the race is a record for a Wisconsin House contest.
The market pays on who wins the seat, not on polls, spending totals or margins. It is a single general election between the major party nominees, so there is no runoff and no split-field effect. The district leans Republican by its partisan baseline (R+7.4), which is why a Democratic win depends on Cooke outperforming it.
| Poll | Fieldwork | Base | Rebecca Cooke | Derrick Van Orden |
|---|---|---|---|---|
| House Majority PAC | June 20-25 | All respondents | 50% | 46% |
Oct. 28, 2026: Van Orden vs. Cooke Polls Split as WI-03 Spending Hits $41.5M
Are There Polls for Van Orden vs. Cooke in Wisconsin's 3rd District?
Public polling of the Van Orden vs. Cooke rematch exists, but every survey in our research is partisan-sponsored and the results disagree. Democratic-sponsored polls show Rebecca Cooke ahead by as much as 4 points. A September Republican poll showed Rep. Derrick Van Orden up 5. On Polymarket's "WI-03 House winner?" market, Van Orden's implied probability of winning was 16% on Oct. 28, 2026, down from 22% three days earlier. We found no nonpartisan public poll of the race.
That 16% is a probability of winning, not a vote share, so it does not translate into a polling margin. Still, a race where sponsored polls land within about 5 points in both directions sits awkwardly with a price that makes the incumbent a clear underdog. That is a tension between the sources, not proof the market is wrong. Van Orden won the 2024 matchup against Cooke by just under 3 points. The period low for the market was 15%.
Why Did Van Orden's Odds Fall From 22% to 16%?
Two developments coincided with the slide. First, coverage of record spending. WisPolitics reported a fresh wave of ads as AdImpact tracked more than $41.5M in the race, the most expensive House contest in Wisconsin history. Cooke and her backers account for about $21.4M and Van Orden and his backers about $20.1M, a gap of roughly $1.3M. Democrats have the seat on the DCCC's "Red to Blue" list, and House Majority PAC leads outside spending, according to Wisconsin Watch.
Second, the race's only debate took place on Oct. 20, hosted by the Eau Claire Chamber and WEAU. There Van Orden said the Iran war makes a Republican hold on the House "exponentially harder." The candidates also clashed over taxes, Channel3000 reported. Van Orden defended the "One Big Beautiful Bill" tax cuts, and Cooke said they favor billionaires.
Other coverage ran alongside these items. An Eau Claire resident filed an ethics complaint alleging that a campaign image of Cooke was AI-generated, and Van Orden's campaign said the image was a real photo from a TV interview. House Speaker Mike Johnson campaigned with Van Orden in Sparta this month. The sources show these events coincided with the drop, but we could not establish that any of them caused it.
What Does the WI-03 House Winner Market Actually Settle On?

Readers can follow the WI-03 House winner market page for live pricing. The verifiable record so far includes the 16% price, sponsor-labeled polls pointing in opposite directions, a $41.5M spending total split almost evenly, and Van Orden's own debate warning about the GOP's House majority.
