The British-based betting firm Ladbrokes says Marine Le Pen is attracting 90 percent of the bets on the eve of the French presidential election, as people gamble that France is in line for an upset.

The betting firm said Saturday despite the polls favoring her centrist rival, Emmanuel Macron, gamblers are putting money on the idea that France may be in line for a political shock similar to Britain’s decision to leave the European Union or Donald Trump’s victory in the U.S. presidential election.

Le Pen’s odds are 6-1. Macron is at 1-10 odds.

Nicola McGeady of Ladbrokes says with “so many political upsets in recent times, we are not surprised to see punters ignoring the polls. Le Pen is attracting the weight of money.”
