About this market
This market will resolve according to the party that controls the Senate following the 2026 U.S. Senate elections scheduled for November 3, 2026. Senate control is defined as having more than half of the voting Senate members, or half of the voting Senate members and the Vice Presidency. If the outcome of this election is ambiguous given the above rules, this market will remain open until the Majority Leader of the US Senate is selected following the 2026 US general election, at which point it will resolve to the party the majority leader is affiliated with at the time of their election to that position. If the elected majority leader does not caucus with any listed party this market will resolve “Other”. Determination of which party controls the Senate after the 2026 US Senate elections will be based on a consensus of credible reporting, or if there is ambiguity, final federal and/or state election authority certification or other final official determination of the 2026 election results.
Frequently asked questions
What is this prediction market about?
This is a Polymarket prediction market asking: "Will the Democratic Party control the Senate 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?

When does this market resolve?
This market is scheduled to resolve on Nov 3, 2026. After resolution, the winning side's tokens redeem at $1 each (in USDC) and the losing side at $0.
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 42.5¢ and the outcome resolves "Yes", you receive $1 per token; if it resolves "No", your "Yes" tokens are worth nothing.
