Just hours before the polls close, we've seen a remarkable alignment of the poll-based and market-based analyses with both projecting around a 22% chance for Trump and a 77% chance for Biden.

It's important to understand that LPR's market-based projection is indifferent to this contract. Rather, LatestPollResults uses each state's (and district's) contract. The discrepancy between a 22% market-based probability on LatestPollResults and the overall contract at PredictIt indicates that traders are underestimating Biden's chances of winning the electoral college OR overestimating his chances to win certain states.
