Jessica Bridge of Ladbrokes told Sputnik of the astonishing furor that the Trump-Clinton showdown caused.
"It was a busier night than both our [UK] General Election and the Brexit vote, easily making it the biggest non-sporting event we have ever witnessed."
The night-owl spending will leave a costly hangover for many Brits who did choose to gamble, because 80% of the money bet, had been banking on Clinton clinching the White House. Indeed, most of the political polls had been predicting a Clinton Presidency.
That will be of little comfort to the one online customer who wagered a staggering US$148,000 on Clinton, at odds of 1/6, late on Tuesday evening.
But as Ladbrokes' Jessica Bridge noted: "Betting on political markets continues to soar and spring surprises."
In the early hours of Tuesday (November 8) evening, Ladbrokes had Mrs. Clinton's odds at 1/10. However, before long, Trump became the overwhelming favorite as swing state results continued to called in his favor.
Betting closed shortly after 07.00 am GMT, with Hillary Clinton at 10/1 and Donald Trump at 1/50.
It's a far cry from the dismissive reaction to when Trump initially declared he was running for president, back in 2015. He was initially chalked up at 150/1.
According to Ladbrokes, this now makes the Republican President-elect the biggest upset in political betting history — an accolade Labour leader Jeremy Corbyn once held as the 100/1 outsider to win the 2015 Labour leadership contest.
First Brexit, now Trump, should I put everything on @jeremycorbyn? Just asking the bookies and pollsters for a friend.— Colin Mackay (@STVColin) November 9, 2016
However, despite most of the total money having been for a Clinton win, interestingly, Ladbrokes has revealed that 75% of individual wagers on the race to the White House had backed Trump.
It means that bookies may stand to lose big despite the majority of the money being bet on Mrs. Clinton. Over 50,000 bets were placed with Ladbrokes alone, across the entire US Election market.
Not placed a bet on this election for a simple reason. I'm afraid after Trump wins, the bookies will go bankrupt and I'll never get paid.— Bill Mitchell (@mitchellvii) November 5, 2016
For those who missed out on betting on a Trump win this time round, Ladbrokes already has his 2020 odds of being re-elected as US President.
Trump at 6/4 anyone?
