Democrats’ Senate odds near 75% ahead of Election Day

November 2, 2026 Last updated 1h ago

With midterm voting set for Tuesday, Kalshi traders put Democrats’ chance of taking Senate control at 74% on Monday, the highest level CNBC said the market had reached since opening in 2024. Final New York Times/Siena polls showed Democratic leads in key battlegrounds, but polling analysts have warned that the surveys could overstate the party’s strength.¹²

TL;DR

The final polls describe Democratic advantages across several pivotal states, but the polling analysis itself stresses the risk of a Democratic overestimate.²³
The market’s roughly 77% estimate adds a measure of confidence in a Democratic Senate takeover, but it still prices in a meaningful chance that the polls will not translate into control of the chamber.^M2

Across the coverage

The Times’ Nov. 1 polling analysis describes Democrats as narrowly ahead in all seven battlegrounds, including Iowa; its Nov. 2 briefing calls Iowa effectively tied and says Democrats have only a slight edge in Alaska.²³

Still to come

Tuesday’s midterm vote will test whether the reported battleground leads become enough Senate seats for Democrats to take control. The Times says the results will also show how accurately its polls and other surveys measured the races.

The market’s shift marks a sharp change from earlier in the campaign, when Republicans dominated the Senate-control contract, according to CNBC. The final Times/Siena surveys showed Democrats ahead in Michigan, Kansas, Texas, Maine and Ohio, with narrower advantages in Alaska and Iowa, leaving the party with a plausible path to a majority.¹²

A separate Senate-control market put the probability of Democrats winning the chamber at about 77% on Nov. 2. That estimate captures substantial confidence in a Democratic win, while leaving meaningful room for a different outcome as voters head to the polls. The market price is not itself a poll, and CNBC notes that prediction markets do not use traditional polling methods.¹^M2

The polls also carry a clear reliability caveat. The Times’ polling analysis says Trump supporters may be less likely to respond to surveys, a pattern that could lead polls to overstate Democratic strength, though it argues the party’s leads could withstand polling errors as large as those in 2016 or 2020. Separately, Times polling found the economy was voters’ leading concern and that Democrats held an advantage over Republicans on handling it.²⁴
