Resolves YES if SCOTUS rules that Trump cannot be barred from the Republican primary ballot under the insurrection clause by the general election next year. This includes a ruling that is not a full reversal of the lower court's decision, so long as the effect is Trump being on the ballot in Colorado.

Resolves NO otherwise (including if they do not take on the case).

This market is about the Colorado court decision about the Republican primary, and will resolve to SCOTUS’s judgement on that. The general election close date is just the latest possible date I would expect it to happen.
