's market on whether Biden will be the nominee is the second-most-traded market on Manifold. Unfortunately, it is a bit unclear from the criteria how the market is supposed to resolve in the unlikely event that the convention nominee is different from the person who is the nominee on election night. Note that the resolution date for the market is Aug 1, and the DNC is later that month.

This market resolves N/A if those two people are the same person. Otherwise, it resolves as the linked market does.
