Today's 2016 Presidential election will become the biggest political betting event ever, according to bookmakers William Hill.
Earlier this week, William Hill said they had already taken more money on the US Election than the General Election in the United Kingdom earlier this year.
And now Hill's are predicting that £20million will be riding on the outcome of the race to the White House.
William Hill spokesman Graham Sharpe told BetOnPolitics.co.uk: "William Hill alone have already taken £3million-plus on the outcome, and with the result still too close to call we expect a political bets bonanza over the weekend and in the final forty eight hours of the Election campaign.
"The campaign has already smashed all previous Election betting records and will end up the biggest betting turnover for any political event.
"We have already seen massive bets for Hillary Clinton - one female client has the largest election bet ever of €550,000 euros riding on her (almost £500,000), another has staked £183,200 on her and on Friday we took two £30,000 bets for her."
Sharpe said two Moscow-based clients have staked five-figure bets on Ms Clinton, while a customer from the north west of England will collect just short of £50,000 should she win.
William Hill say that as of Saturday, 67.5% of the individual bets they have taken have been for Donald Trump, but 72% of all the stake money is for Clinton.
"The campaign has mirrored Brexit in that there have been far more individual bets for the outsider, but the biggest bets have been on the favourite," Sharpe added.
