About this market
The 2026 midterm elections are scheduled to be held on November 3, 2026. This market will resolve according to the number of seats held by the Republican Party in the US Senate as a result of the 2026 midterm elections. This market will resolve based on the results of all Senate elections, including special elections, that are scheduled to occur in November 2026 as of October 31, 2026. If a required runoff for any such election could change the market’s outcome, the market will remain open until that runoff is conclusively called by this market’s resolution sources. If a Senate seat is vacant but a corresponding election is not held in November 2026, the seat will be considered held by the party of the seat's most recent incumbent. A candidate's party will be determined by their ballot-listed or otherwise identifiable affiliation with that party at the time all of the 2026 Senate elections are conclusively called by this market's resolution sources. A candidate without a ballot-listed affiliation to either the Democratic or Republican parties will be considered a member of one of these parties based on the party with which they most recently expressed their intent to caucus at the time all of the Senate elections are conclusively called by this market's resolution sources. The resolution source for this market is the Associated Press, Fox News, and NBC. This market will resolve once all three sources have conclusively called all Senate elections. If all three sources do not achieve consensus in calling the relevant races for this market, it will resolve based on the official certification.
Frequently asked questions
What is this prediction market about?
This is a Polymarket prediction market asking: "Will the Republican Party hold 47 or fewer Senate seats after the 2026 midterm elections?". Traders buy "Yes" tokens if they think the event will occur, or "No" tokens if they think it will not. Each token's price (in cents on the dollar) represents the market's consensus probability of that outcome.
What is the current probability?
The market currently prices "Yes" at 23.5¢, which implies a 24% probability. "No" trades at 76.5¢. The probability updates in real time as traders buy and sell.
How is the outcome decided?
Resolution follows Polymarket's standard process via UMA's optimistic oracle: a proposed outcome is submitted, and anyone may dispute it within a challenge window before settlement.
What does buying YES or NO actually mean?
"Yes" and "No" are outcome tokens on the Polygon blockchain. Each one pays out $1 in USDC if its outcome resolves true, otherwise $0. If you buy "Yes" at 23.5¢ and the outcome resolves "Yes", you receive $1 per token; if it resolves "No", your "Yes" tokens are worth nothing.
