Resolution rules

Each outcome is a separate contract with its own rules. The rules for At least 10:

If the number of U.S. Senate seats won by Democratic Party candidates is at least 10 in the 2026 U.S. Senate elections, then the market resolves to Yes.

Caucus affiliation, endorsements and later party changes do not affect the count: a member elected without a Democratic designation who caucuses with Democrats is not counted, and one elected as a Democratic candidate who later leaves remains counted. All 35 U.S. Senate contests on the November 3, 2026 ballot count, including the Florida and Ohio special elections. No seat counts twice.

A seat is counted when at least four have declared its winner with no contradictory declaration then outstanding; withdrawn or superseded declarations are disregarded. A seat not counted under that four-of-eight test is attributed to the candidate the state certifies as elected. A runoff seat is counted when that contest is called. Designated Media Source declarations. For United States…
