Paddy Power Betfair Plc, Irelands largest bookmaker, is paying out 120,000 euros ($130,000) on Donald Trump winning the U.S. Republican presidential nomination.
Trump and Democrat Hillary Clinton each won seven states on their way to commanding victories in Super Tuesday contests.
Since 1988, the candidate to clean up on Super Tuesday has always gone onto win their partys nomination, the Dublin-based bookmaker said in e-mailed statement on Wednesday.
Gambling companies pay out early when they regard the result as a foregone conclusion, in part because it draws publicity and in part because gamblers often recycle winnings into other wagers. For example, Paddy Power paid out early on David Camerons 2010 election victory and the 2014 Scottish referendum result.
Trumps odds indicate he has a 33 pecent chance of winning the White House, while Clinton has a 65 percent shot, Paddy Power Betfair said.
