75 days to election: Betting odds favor Harris over Trump but not to Biden, Clinton levels

Bettors are almost evenly split on their pick 75 days before the presidential election in a sharp break from where the action stood at the same point in the last two elections.

Vice President Kamala Harris holds the narrowest lead over former President Donald Trump of any recent Democratic nominee at this point in the election, sitting at -102 at U.K. bookmaker Betfair Exchange. By contrast Hillary Clinton's odds stood at -323 at the 75-day mark, but Clinton went on to lose the election in one of the two times the betting underdog won on election night.

The action, which U.S. bookmakers cannot legally take part in, has so far built a pot that is larger than the 2016 election at the 75-day mark but falls slightly below the 2020 mark at Betfair. The exchange shows the markets for the presidential race was approximately:

• 2016: $38 million
• 2020: $79 million
• 2024: $70.5 million

Here's where the betting odds stood for each of the last three elections 75 days before election day.

How accurate have election odds been in past presidential elections?

The betting favorite has only lost twice since 1866 , according to the Conversation, a nonprofit news organization.

The two upsets came in 1948, when Harry Truman (D) beat eight-to-one odds to defeat Thomas Dewey (R), and in 2016.

Bettors did not put their money on Minnesota Governor Tim Walz when the market opened for Harris' vice-presidential pick. Pennsylvania Governor Josh Shapiro and Arizona Senator Mark Kelly were the punter's favorite through most of the veep-stakes, with Walz shooting up the odds boards in the final days.
