I may not have been clear about it in my previous post but for "who will win the popular vote" I'm most incredulous about today's prices, not the ones from election night. Back then there was uncertainty, but now there's no way Trump wins the popular vote unless all of the voter fraud conspiracies are true.

Even if something awful happens and Biden isn't able to take office, he'll still win the popular vote. I think betting size limits are the main issue, combined with people betting against Trump diffusing their bets in correlated markets.
