Odds have shortened on Joe Biden entering the White House as the Democratic challenger and president Donald Trump await the results of an unprecedented election campaign.
As of Thursday morning, online gambling company BetFair was giving Mr Trump a 4/1 chance of winning re-election. The odds for Mr Biden were 1/6.
While national polls had shown a landslide for Mr Biden, in reality the results were a lot closer in some states than Democrats had hoped.
But the odds on Mr Trump securing a second term lengthened significantly as his opponent won key battlegrounds such as Wisconsin and Michigan.
After a rollercoaster 24 hours, it looks like Donald Trump’s prospect of re-election is finally starting to fade significantly as his route to victory narrows again, said Betfair spokesperson Sam Rosbottom.
A record $609m (£466m) has been bet on the outcome of the winner on Betfair Exchange as of Wednesday night. Of that money $318m (£244m) went on Mr Biden and $290m (£222m) on Mr Trump.
The 2016 presidential election also saw a record number of people place bets, as $258m (£198.7m) was spent gambling on the contest between Mr Trump and Hillary Clinton on Betfair Exchange.
Mr Rosbottom said: The 2020 election is on course to become the biggest single betting event of all time.
