Donald Trump’s election win over Hilary Clinton to become the 45th President of the United States is expected to result in a six figure profit for London-based spread betting firm Sporting Index.

The company benefited from unprecedented interest in the election, with a substantial number of bets taken after 10pm on Tuesday all the way through to the early hours of this morning.

Trump, the Republican nominee, won the key swing states of Florida, Ohio and Pennsylvania to triumph in the election. His shock victory in Wisconsin put him over the 270 electoral college votes needed to take him to the White House.

With four states yet to declare, Trump could still hit 300 electoral college votes. It is some turnaround as Sporting Index revealed that on Monday, Clinton was expected to win 325 electoral college votes with Trump predicted to land just 213.

“Five months of hard work has gone into our election book, covering all of the scandals, midnight suspensions of markets and more,” said Ed Fulton, political trading spokesman for Sporting Index. “The most divisive election in history has also proved to be one of the most volatile.

“While many expected Hillary to walk away with the keys to the White House, we were happy to take her on and that has paid off. The further Trump wins by the better for us.”
