A leading betting agency is already paying out on Scotland voting No despite polls seemingly showing the result is too close to call.
After another weekend of heavy trading on the Betfair Exchange, the company has enough confidence to hand over a substantial six-figure sum on the No vote for bets placed before 11am on Tuesday.
Betfair believes its predictor is accurate when it comes to political outcomes and has continually expressed a 79% likelihood of a No vote since the market opened last year.
Spokeswoman Naomi Totten said: “To put the current prices into context, Betfair’s markets gave Mitt Romney more of a chance of beating Barack Obama in 2012 than Alex Salmond currently beating the No campaign on Thursday.”
There has been little sign of the Yes vote gaining any traction with political bettors, with trading at 7-2.
The exchange will continue to trade until Friday’s official announcement.
