As soon as Joe Biden entered The White House in January 2001 markets opened on who would win the Presidency in 2024. Gamblers and bookmakers have been trying to pick the outcome ever since.

In this article we will examine and update the odds changes during the run up to election day on November 5th 2024.

10th September 2024

With less than 2 months until election day on the 7th November Donald Trump and Kamala Harris are set to have their first televised debate tonight.

Star Sports have priced the winner of the debate up with Harris 1/3 favourite and Trump at 2/1.

In the main market on who will win the election Trump is favourite at 1.93 and Harris is 2.16. It will be interesting to see if the debate has any effect on the odds. 

The result of the election will come down to who wins the swing states. Betfair now have markets up on who will win every state.

The key swing states are Arizona, Georgia, Michigan, Nevada, North Carolina, Pennsylvania and Wisconsin. The table below shows the Betfair exchange back price available for each party to win each state (Odds correct 10th September 2024)

StateRepublicansDemocrats
Arizona1.552.66
Georgia1.672.44
Michigan2.41.72
Nevada1.972
North Carolina1.512.72
Pennsylvania1.932.06
Wisconsin2.41.71

If we assume that the Republicans and Democrats win all the states they are sub 1.9 to win the election comes down to Nevada and Pennsylvania. In reality the 19 Electoral College votes in the Pennsylvania look to be the current key to this tight race.

But a lot can change in the next 2 months.

8th August 2024

In the last two weeks there has been a big turn around in the prices for 2024 Presidential Election.

The odds for Michelle Obama, Gavin Newson and Kamala Harris remain unchanged.

1st June 2024 :The story so far

The latest national polls collated on  fivethirtyeight.com have been relatively steady for the last 3 months. 

Trump ended May on 41.1%, Biden 39.7 and Kennedy on 9.8%, giving Trump a 1.3% lead over Biden.

Will Donald Trump regain the White House?

Trump starts June priced at 1.07 with the Betfair Exchange to be the Republican Nominee. He was as big as 11.0 back in 2001 when it was unclear if he would run for President again after not returning to The White House after the 2000 election.

His biggest Republican rival early in the campaign was the Governor of Florida, Ron DeSantis, who traded as low as 1.84. Nikki Haley was the last candidate to suspend her campaign leading to Trump officially became the party's presumptive presidential nominee.

Trump is available at 1.99 on Betfair to win the 2024 Presidential Election. His price has fluctuated wildly over the last 3 years from a high of 21.0 to a low of 1.84. In the last week after the verdict of the Stormy Daniels court case his odds went from 1.9 to 2.4 back to 1.99.

With the bookmakers Trump is 1.91 with Unibet, BetMGM, Star Sports and AK Bets.

What are Joe Biden's chances of winning a second term?

Biden is 1.15 on Betfair to be the Democratic Nominee. Michelle Obama is 20.0 and California Governor, Gavin Newsom, is 32.0. With the bookmakers Biden is 1.1 with Skybet, Coral, Star Sports and Ladbrokes to be the candidate.

At the start of his Presidency it was unclear is Biden would stand for a second term. He was as big as 4.9 to be the Democratic Nominee. He announced he was running again on 25th April 2023. 

Going into June, Biden is currently 2.56 to win a second term on Betfair. With the bookmakers he is 2.5 with Coral, Unibet and BetMGM.

Could there be a different President?

Robert F. Kennedy Jr is polling nationally at around 10% and is 42.0 on Betfair to win. 

If Biden or Trump drop out of the race the Democrats potentially have Michelle Obama (34.0 with Betfair and 26.0 with AK bets and Star Sports), Gavin Newsom (70.0 with Betfair and 51.0 with Coral and Unibet) and current Vice-President, Kamala Harris, at 100.0 with Betfair. She is generally available at 67.0 with the bookmakers.

Nikki Haley is 100.0 on Betfair for the Republicans. 

Which party is predicted to win?

On Betfair, the Republicans are 1.9 and the Democrats are 2.2 to win the Presidency. Any other party is 38.0. The bookmakers generally have the Republicans at 1.8. Star Sports are an outlier with the Democrats at 2.2.

For the popular vote the Democrat candidates are favourite with Biden at 1.44 on Betfair and Trump at 4.3. Winning the Presidency is about campaigning to win the most Electoral College votes and not the popular votes. 

That concludes the roundup of the odds at the start of the summer. It is going to be an interesting 5 months in the run up to polling day on 5th November 2024.
