We realistically won't know for a few days. Voting turnout this year has exploded, and mailed in votes still have to be received and processed. Less than half of all states are expected to have counted 98% of ballots by November 6th, and the rest will likely take at least a week to reach a 98% count. Especially in any places with slim margins, this is crucial. The Trump campaign is expected to be suing states to end ballot counts early, the Biden campaign will be countering those suits. It's going to be a mess.
