US Presidential Election Betting Odds

The United States holds a presidential election once every four years to decide who will become president. Elections are decided by the Electoral College, with 538 votes available and 270 needed to win. Each state has a number of votes roughly based on its population, and in most cases all of a state’s votes go to the candidate who wins there.

The last US election was held on 5 November 2024 and saw the Republican Party’s Donald Trump defeat the Democratic Party’s Kamala Harris to become the 47^th President of the US. The betting markets had both Trump and Harris similarly priced in the build-up to the election, so the strong Republican win was somewhat of a surprise.

US Election FAQs

When is the next US Election?

The next election will be held on 7 November 2028. Elections are held every four years and occur on the first Tuesday of November in the election year.

Who is running in the US Election?

Anyone who is a “natural-born” US citizen, is at least 35 years old, and has been a resident in the US for at least 14 years can run for president. However, the US political landscape today is dominated by two parties: the Democrats and the Republicans.

There are other small “third” parties like the Libertarian Party and the Green Party, as well as independent candidates not affiliated with any party. However, nobody outside the two major parties has been elected president in over a century.

Who is the favourite for the US Election?

The Democratic Party is the favourite to win the next US election, currently priced at 4/6 to re-enter the White House in 2028. This would be the first Democratic victory since Joe Biden won in 2020, and would be the 18^th Democratic candidate to hold office.

How can I bet on the US Election?

You can find a range of political betting markets on the Spreadex website and app, including the winner of the next US election. More markets will also be released closer to the election date.

US Election Betting Odds

The Democrats are the favourites in our fixed odds betting markets, currently priced at 4/6. The Republicans are slightly longer, priced at 13/10 to stay in the White House. You can also back any other party to win the election at 35/1.

Gavin Newsom is one of the favourites to become the 48^th president, with the Governor of California currently priced at 18/5. Vice President JD Vance is also priced at 18/5, with many expecting him to lead the Republican ticket for the 2028 campaign. Donald Trump is ineligible for re-election as he served the constitution-mandated maximum of two terms as president.

Our markets also include some much longer shots like former First Ladies Michelle Obama and Hillary Clinton at 70/1 and 400/1 respectively, or independent 2020 candidate Kanye West at 500/1.
