Donald Trump has seen his initial odds of 100/1 in November 2012 freefall to 9/2, representing a 18.2% chance of winning.
Féilim Mac An Iomaire, a spokesperson for Paddy Power, said: "Trump gave it a hell of a shot going from a rank outsider to the Republican candidate but the recent flood of revelations have halted his momentum and his chances now look as patchy as his tan.
"Recent betting trends have shown one way traffic for Hillary and punters seemed to have called it 100% correct. Despite Trump’s Make America Great Again message appealing to many disillusioned voters, it looks as though America are going to put a woman in the White House."
Should Trump upset the odds and become 45th President it will trigger the biggest political payout in bookmaking history and leave Paddy Power with some very expensive pie on its face.
Paddy Power continues to offer betting right up to and including Election Day. One of the most popular bets currently on offer is predicting the winning margin of the successful nominee on November 8th.
