Betting Odds for 2024 Election: Trump vs. Harris

Who’s Leading the Betting Odds: Kamala Harris or Donald Trump?

During the Democratic National Convention (DNC) in Chicago this week, the favorite to win the 2024 presidential election switched between Kamala Harris and Donald Trump multiple times.

At the start of the DNC, Harris was slightly favored to win. However, Trump took the lead on Tuesday, becoming the top choice at Pinnacle, a respected offshore sportsbook not regulated in the U.S. On Wednesday, Trump continued to lead at Betfair Exchange, based in London, where over $70 million has been wagered on the election.

Betfair noted that while more money has been bet on Trump, Harris has received more individual bets. According to Betfair spokesperson Sam Rosbottom, “The odds have flipped dramatically in the last 24 hours. With just under three months until the election, expect more fluctuations as the campaigns intensify.”

Harris regained the lead on Thursday after delivering the closing speech at the DNC. By Friday, she was again the favorite at Betfair with +100 odds, while Trump’s odds were +108.

A positive number in betting means how much you could win on a $100 bet. So, betting $100 on Harris would win you $100 if she wins, and $100 on Trump would win you $108.

On Friday, Pinnacle had nearly equal odds for both candidates, with Trump at -109 and the field (any other candidate) at -111. A negative number indicates how much you need to bet to win $100. For Trump, you would need to wager $109 to win $100.

Betting on politics is not allowed at U.S. sportsbooks.

According to electionbettingodds.com, Harris has a 50% chance of winning, equating to +100 odds, while Trump’s chances are 48.2%, or +107. After a failed assassination attempt on July 13, Trump's odds were as high as 67.9% (-211).

President Joe Biden withdrew from the race on July 21 and endorsed Harris, who became the leading candidate on August 9.
