The rules, in plain English
If the Democratic Party has won control of the U.S. Senate in 2026, the market resolves to Yes. The market may be determined early based on a consensus of media calls projecting control of the U.S. Senate (see full rules for details). Otherwise, victory will be determined by the party identification of the President pro tempore of the Senate on February 1, 2027.
What the rules leave open
Whether a 50-50 Senate split counts as Democratic control depends on which party holds the Vice Presidency (tie-breaking vote), but this is not explicitly stated.
