Hillary Clinton has an 85 percent chance of winning the U.S. presidential election, at least according to two prominent U.K. betting companies.

Those considering placing money on the outcome of the U.S. election can get odds of 2/11 with Ladbrokes and Betfair, which implies an 85 percent probability of a Clinton win. At those odds, the gambler would receive just 18 cents for every dollar they bet.

Unfortunately for rival candidate Donald Trump, the odds of him winning the election are 6/1 (a 15 percent chance) according to Betfair, though any gamblers backing him would win back their stake six-fold. Ladbrokes has slightly better odds at 4/1.

"Trump's odds have been drifting like a barge with the bookies in the past few weeks, however it looks like punters are hedging their bets thanks to the big prices on offer," said Jessica Bridge from Ladbrokes in a press release.

"At 2/11 Clinton would appear to be safe, but this two-horse race isn't over yet according to the cash being wagered on both candidates."

British bookmakers base their odds on how much money they receive: The more money it receives for Clinton to win, the lower the odds.
