2026 Senate Races — Every Seat, Every Market

The full 35-seat board with a coverage flag on each one: live, thin, or no market at all. 35 seats carry a tradeable Kalshi contract. That is every seat on the ballot.

Quick Answer

As of October 15, 2026, Kalshi prices Democrats to control the Senate at 61%. 35 of the 35 U.S. Senate seats on the 2026 ballot have a tradeable Kalshi contract, and 35 of those 35 are returning live prices on this refresh. Every seat on the ballot carries a market.

The ballot: 33 regular Class 2 seats plus two Class 3 specials — Ohio (the Vance seat, now held by appointee Jon Husted) and Florida (the Rubio seat, now held by appointee Ashley Moody). Fifteen states have no 2026 Senate race.

A seat with no live card below is not a seat we dropped. Every defined race renders whether or not the venue answered, so the board can never quietly shrink to whatever came back.

The Board — Sorted by Competitiveness

35 of 35 with live prices

Tightest races first — a leading price near 50¢ is the market saying it genuinely does not know. Cards without prices are seats whose contracts returned nothing on the last refresh; they stay on the board with an honest badge rather than disappearing.

Senate Control & Seat Count

Kalshi seat-count ladders

Rather than a binary, these let you position on the exact seat count each party holds after January 2027. The shape of the ladder tells you where the market sees the realistic ceiling and floor — divergence from the seat-by-seat board above is the signal.

2026 Senate markets — frequently asked

Which 2026 Senate races have prediction markets?

35 of the 35 Senate seats on the 2026 ballot have a tradeable Kalshi contract, including the two Class 3 specials — Ohio, for the seat JD Vance vacated, and Florida, for Marco Rubio's. The full seat-by-seat table on this page names every one, with the coverage flag we read off the live book rather than off a press release.

How many Senate seats are up in 2026?

35 — the 33 regular Class 2 seats plus two Class 3 special elections in Ohio and Florida, each filling a seat vacated mid-term and now held by an appointee. 15 states have no 2026 Senate race at all: Arizona, California, Connecticut, Hawaii, Indiana, Maryland, Missouri, Nevada, New York, North Dakota, Pennsylvania, Utah, Vermont, Washington, Wisconsin. Their Class 1 and Class 3 seats are not on this ballot.

What does a "thin market" flag mean here?

That a contract is listed and quoted but is not carrying real two-way interest — no recent 24-hour volume, or open interest under our floor. A thin price is still a price, but it reflects whoever last posted a quote rather than a crowd, so we label it instead of letting it sit next to a heavily traded race as though the two carry the same weight. Safe seats are thin for the honest reason that there is nothing left to argue about.

Are Senate contract prices the same as a poll?

No, and the difference is the point. A contract at 60 cents is real money assigning a 60 percent chance, repriced continuously by traders who lose if they are wrong; a poll is a sample of stated intention at one moment. They disagree often, and where they do we show the gap rather than picking a winner — the Markets vs Pundits board puts each live Senate price next to the most recent published rating from a named forecaster.
