Bookmakers have made Her Majesty a late favourite to light the Olympic cauldron at the opening ceremony for the 2012 London Games.
A spokesman for BetFred told The Huffington Post UK said a late surge of betting came on Friday morning, slashing the Queen's odds to 5-1, from 25-1.
"We've had around 400 bets on the Queen, you can never tell what sparks it. It might be a royal insider, or just a right royal gamble."

Rower Sir Steve Redgrave, who won gold at five consecutive Olympics, is still the favourite to light the cauldron, with bookmakers putting his chances at 10-11.
Sir Roger Bannister, who ran the first four-minute-mile, is also a hot favourite.
David Beckham and Tour de France winner Bradley Wiggins are also outside chances, according to the Guardian.
A Facebook group is also calling for controversial WikiLeaks founder Julian Assange to light the torch, mocking up a picture of the Australian anti-secrecy campaigner holding the golden torch.
Assange is currently holed up in Ecuador's London embassy, where he is claiming political asylum to avoid extradition to Sweden on sex assault allegations.
