How each venue defines this

Each exchange's own settlement text, quoted as written. Where they differ, the difference is usually why the prices do.

These two contracts name settlement dates about 2 months apart. Read both terms below for why: a later date can mean a different condition, a longer deadline or an administrative delay, and only the terms say which.

The resolution source for this market is the Associated Press, Fox News, and NBC. This market will resolve once all three sources call the race for the same candidate.
