Frankel is 11/10 to remain unbeaten throughout 2012 with BetVictor, after he stormed to a five-length win in the JLT Lockinge Stakes.
Sir Henry Cecil's colt has now won each of his 10 starts and could head to Royal Ascot next, where he's 1/3 for the Queen Anne Stakes with William Hill, although connections are also said to be considering the Princes Of Wales' stakes.
William Hill also quote Frankel at evens to remain unbeaten this season, while Paddy Power offer prices on how many times he meets defeat, with one priced at evens, two at 16/1 and three or more a 100/1 chance.
Lucy Rhodes, spokeswoman for Hill's, said: "With the Champions League and Scottish Cup finals, plus Frankel stamping his authority in superlative style, this has been an epic weekend for sport, and there is no doubt the world's greatest racehorse was a sure-fire banker in thousands of multiples across the land."
Over at Newmarket, Thought Worthy won the Listed Fairway Stakes and was cut to a general 33/1 for the Investec Derby as a result.
John Gosden's horse had to battle hard for his victory and touched 47/1 in-running on Betfair, but had a neck in hand over Noble Mission at the line.
The runner-up, a full brother to Frankel, touched 1.12 in-running having looked like he might get up late on, and he's out to 33/1 for the Epsom Classic.
