There are a lot of questions surrounding the championship matches at WrestleMania 31, and who will leave the pay-per-view with each belt. While some of the matches might not be easy to predict, the oddsmakers expect there to be a few title changes at WWE’s biggest event of 2015.

It had long been presumed that Roman Reigns would win the WWE World Heavyweight Championship at WrestleMania 31, but he is no longer the favorite to be victorious in the main event. Brock Lesnar was the underdog after the March 23 edition of “Monday Night Raw,” but he has since been tagged as the favorite in his match against the former Shield member. The turning point came on Tuesday night when Lesnar announced on ESPN that he signed a new contract with WWE. Many had expected the champ to return to UFC, following WrestleMania 31.

Daniel Bryan was favored to win the WWE World Heavyweight Championship a year ago, and he went on to do so at WrestleMania 30. But the oddsmakers don’t always get it right, considering The Rock was a significant underdog when he beat John Cena in the main event of WrestleMania 28.

The Undertaker was the biggest favorite at WrestleMania 30, but he lost to Lesnar in what might have been the most shocking moment in WWE history. Even though his WrestleMania streak is no longer intact, it’d still be a surprise to see him lose on Sunday. In his match against Bray Wyatt, The Undertaker is the second-biggest favorite on the card.

The one wrestler on the card that has never wrestled in a WWE match is the biggest favorite at WrestleMania 31. Sting has been given -700 odds to defeat Triple H. The COO has been defeated in his last four PPV matches, losing twice to The Shield as part of Evolution, and previously losing to Bryan and Lesnar.
