The final midterm election predictions all lean the same way: Democrats are strong favorites to win the House, while the Senate is closer but tilts their way. With Election Day on November 3, here is what each major forecaster and market said in the final days, and where they differ.
Key facts (as of November 2026)
- Decision Desk HQ’s model gives Democrats an 84% chance of winning the House and a 64% chance of winning the Senate (November 2 update).
- Kalshi and Polymarket both priced a Democratic House at 94% and a Democratic Senate at 72% at noon ET on November 1, Benzinga reported.
- Republicans go into the vote holding the Senate 53–47 and the House 218–214, so Democrats must gain four seats overall in each chamber.

What are the midterm election predictions for the House?
Every major forecast has Democrats ahead for the House, and by a wide margin. The disagreement is only over how big the gain could be. Decision Desk HQ (DDHQ) projects about 241 Democratic seats, which is 23 more than the 218 needed for a majority.
Silver Bulletin's FLIPR model is even more confident. Its November 1 update gave Democrats roughly a 95% chance and an average net gain of 25 seats. The Cook Political Report, which rates races by hand rather than by simulation, expects Democrats to pick up between 12 and 25 seats, according to Newsweek's write-up of Cook's October 30 changes.
| Forecaster | Method | House | Senate | Date |
|---|---|---|---|---|
| Decision Desk HQ | Simulation model | 84% Democratic, about 241 seats | 64% Democratic, about 52 seats | Nov 2 |
| Silver Bulletin (FLIPR) | Simulation model | About 95% Democratic, average gain of 25 | Democrats favored, closer than the House | Nov 1 |
| Cook Political Report | Expert race ratings | Democratic gain of 12 to 25 seats | Democratic gain of 2 to 6 seats | Oct 30 |
| Kalshi and Polymarket | Prediction markets | 94% Democratic, about 235 seats | 72% Democratic | Nov 1 |

What do forecasters expect in the Senate?
The Senate is where the uncertainty sits. DDHQ's 64% for Democrats means Republicans keep control in about one simulation in three. Because Vice President JD Vance would break a 50–50 tie, Democrats need 51 seats outright.
As of November 2, DDHQ rates three Senate races as toss-ups. Kansas is dead even at 50%. In Iowa, the model leans slightly toward Republican Ashley Hinson (53%), while in the Ohio special election it leans slightly toward Democrat Sherrod Brown (55%).
Beyond those, each side has seats it is favored to hold or win. DDHQ leans Democratic in Alaska, Texas and Maine (61% to 63%). On the other side, it leans Republican in South Carolina (62%) and Nebraska (73%) and rates Florida likely Republican (75%).
Cook's Senate editor Jessica Taylor called Democrats the "slight favorites" in Cook's latest update. However, Cook also noted that Republicans could still hold the chamber, especially if polls are underestimating Republican support.
Why do the models and markets give different numbers?
They use different inputs. DDHQ and Silver Bulletin both run thousands of simulated elections built from polls and other signals, such as fundraising and incumbency. FLIPR also adds expert ratings like Cook's as a final layer, Silver Bulletin explains.
Prediction markets work another way. Their percentages come from what traders are willing to pay, so they can react to news within minutes. That is why the markets put the Senate at 72% for Democrats, eight points above DDHQ. Our explainer on prediction markets vs. forecast models goes deeper, and the generic ballot polls show the national mood the models feed on.
Races can also split the sources. For example, Iowa polling averages cited by Benzinga showed Democrat Josh Turek narrowly ahead, yet both markets still gave Hinson the edge. So a single number never tells the whole story.
How much can you trust midterm election predictions?
Treat them as odds, not results. An 84% chance still leaves a 16% chance for the other party, and polling misses tend to run in the same direction across many states at once. Silver Bulletin made that point on November 1 by laying out 13 possible maps, ranging from excellent to terrible for Democrats.
In short, the forecasts describe the evidence going into Tuesday. Then the counting decides. Close races in states that count mail ballots late, or that use ranked-choice voting such as Maine and Alaska, may take days. Our guide to when we will know the midterm results explains why, and the live tracker above will switch to called races on election night.

Frequently asked questions
Who is predicted to win the 2026 midterms?
Democrats are favored to win the House in every major forecast, with chances between 84% and about 95%. The Senate is closer: DDHQ gives Democrats 64% and the markets about 72%, so a Republican hold remains possible.
Are midterm election predictions ever wrong?
Yes. A forecast is a probability, so the less likely outcome happens some of the time. Also, if polls miss in one direction across many states, several close races can flip together.
Which Senate races are toss-ups in the final midterm election predictions?
DDHQ's November 2 update lists Kansas, Iowa and Ohio as toss-ups. Alaska, Texas and Maine lean Democratic, while South Carolina and Nebraska lean Republican.
