Wales are now odds-on 8/11 favs to secure the Triple Crown with Ladbrokes and 11/10 to win the Six Nations tournament.
Wales head into their match with England as 2 point handicap favs while the English are 6/5 from scratch.
Following the postponement of France v Ireland, Wales are now just 11/10 to win overall and the French are out to 13/8.
Ladbrokes are still going for no Grand Slam winner as their 5/4 market fav but Wales are 2/1 to achieve it this year with England an 11/1 chance.
Alex Donohue of Ladbrokes said: “It was a real game of two halves for us. Wales were supported to cover and going into half time we gave ourselves a good chance of dodging the gamble.”
He added: “Wales were backed for the Triple Crown, Tournament and Grand Slam following their World Cup so we’ll be in the unusual position of cheering on England at Twickenham.”
