Resolution rules

Verbatim from the venue. The analyst must quote these, never paraphrase.

If the Democratic Party has exactly 51 Senate seats on Feb 1, 2027, then the market resolves to Yes.

Individuals caucusing with either party will be included with them (e.g. an Independent who caucuses with a party, like Vermont Senator Bernie Sanders who caucuses with the Democrats, would be counted as a Democrat).
