PANews reported on November 2 that according to Cryptoslate, on the prediction market Polymarket, Harris's chances of winning in Michigan and Wisconsin exceeded Trump's. If Harris wins these two swing states, Pennsylvania will become a key factor in determining who wins the US presidential election.

The odds have swung sharply in Harris' favor in two of the six "battleground states" since an SRSS poll published on CNN on October 31 showed neither candidate had a clear advantage. As a result, Harris's odds of winning Wisconsin and Michigan have risen by 5% and 6%, respectively. In addition, her overall odds of winning the entire election have risen from 2.3% to 39.6%, but are still far lower than Trump's 60.3%. Trump's overall odds of winning are 22.2% higher than Harris's. Trump also leads Harris by 14% in Pennsylvania and has large leads in the remaining three swing states: Arizona, Georgia, and Nevada.
