Trump's chances of winning on Polymarket and Kalshi fell 10% from the high point

Ahead of Tuesday’s upcoming U.S. presidential election, all major prediction markets continue to predict former President Trump’s odds over Vice President Harris. However, Trump’s odds on prediction markets have fallen by an average of 3.8% over the past week, according to ElectionBettingOdds.com. Trump’s odds on Kalshi and Polymarket have fallen by more than 10% from their all-time highs. As of press time, Trump’s odds on Polymarket have fallen from a high of 71.5% reached on July 16 to 59.1%, while his odds on Kalshi have fallen from a high of 65.2% on October 29 to 55% currently (Kalshi’s prediction market went live on October 4). Trump’s odds on Polymarket fell to 57.1% on Saturday (a 15-point difference from Harris’s 42.8% odds), before recovering slightly. Election watchers are closely watching early voting results and late polls, including one that showed Harris leading among Puerto Ricans in Florida after comedian Tony Hinchcliffe spoke at Trump's rally at Madison Square Garden last week. At Polymarket, Harris also leads in Wisconsin and Michigan, two swing states seen as key to winning. The prediction market posted on X that "Harris is gaining ground." (The Block)
