Resolution criteria

This market resolves to the single option that accurately reflects John Fetterman's official party registration/affiliation and formal caucus membership in the United States Senate as of 11:59 PM ET on July 1, 2027.

• Democrat: Resolves to YES if Fetterman is officially registered as a Democrat and formally caucuses with the Senate Democratic Caucus.

• Independent/Third Party, Caucuses with Democrats: Resolves to YES if Fetterman is registered as an Independent, unaffiliated, or with a third party, and formally organizes/caucuses with the Senate Democratic Caucus.

• Independent/Third Party, Caucuses with Republicans: Resolves to YES if Fetterman is registered as an Independent, unaffiliated, or with a third party, and formally organizes/caucuses with the Senate Republican Conference.

• Republican: Resolves to YES if Fetterman is officially registered as a Republican and formally caucuses with the Senate Republican Conference.

• Not A Member of the Senate: Resolves to YES if Fetterman is no longer a Senator for any reason.

Resolution Rules & Sources:

• Official caucus and party affiliation will be verified primarily via the official directory on the United States Senate website and the Biographical Directory of the United States Congress.

• Party registration status can also be verified by official Pennsylvania voter registration records or official statements issued by the Senator's office.

• If Fetterman does not hold office as a U.S. Senator on July 1, 2027 (e.g., due to resignation, expulsion, or death), this market will resolve according to his official party registration and intended caucus status at the time of departure, or resolve N/A if that cannot be determined.

• If an outcome occurs that does not fit into any of the available options (e.g., registered Democrat caucusing with Republicans, or an Independent refusing to caucus with either party), the market will resolve N/A.
