The result of Tuesday's U.S. presidential election – and the impact it will have on the country's 346 million residents – certainly qualifies as "high stakes".

But even that isn't enough for some action enthusiasts who will also have six-figure wagers (or larger) hinging on the result of the 2024 election.

With betting exchanges like Kalshi and Polymarket offering opportunities for bettors to lay millions on an assortment of presidential election odds, high rollers have been loading up on action as the election draws nearer. And you can expect the volume of wagers to skyrocket next week, when voters will decide between the former present and the current vice president.

The latest Donald Trump odds at the top political betting sites show the former president with the lead at -163, while the Kamala Harris odds sit at +140.

Here's a look at the most sizable wagers so far on the U.S. presidential election (list updated Nov. 5 at 6 a.m. ET):

Trump had been approaching the -200 range at the majority of the political betting sites in Canada, but has seen significant odds clawback over the past couple of days.

Where the odds go from here remains to be seen, though bettors and casual observers alike should expect plenty of additional movement over the next several days, highlighted by a whirlwind of activity on Nov. 5.

Where to Bet: Presidential Election Betting Sites

Where to Bet in the U.S.

U.S. election betting is expressly forbidden all of the best sports betting sites, but betting exchanges and prediction market operators like Kalshi, Robinhood and PredictIt are allowed to offer opportunities for bettors to lay money on election-related outcomes.

Polymarket is another renowned prediction site offering bettors a route to election betting, but it does not operate in the U.S. at present.

Where to Bet in Canada

Ontario is the only Canadian province with a fully regulated sports betting environment at the moment – and unlike their American brethren, Ontarians can legally wager on a wide assortment of U.S. election markets.

Among the secondary markets offered by Ontario sports betting sites like DraftKings, FanDuel and bet365 are Electoral College results, winning candidate by state, and total vote range.

Where to Bet in the UK

Like Ontario-based bettors, UK punters have a fully legal path to U.S. presidential wagering.

Both UK sports betting sites and regulated exchanges take wagers on a variety of primary and secondary election markets.
