If the last few years are any indication, there will be at least one major surprise at WrestleMania 32. That could mean Roman Reigns will lose the WWE World Heavyweight Championship match in the main event for a second straight year.

Reigns (-700) is a heavy favorite to defeat Triple H (+400), who won the title at the Royal Rumble. For months, it’s been expected that Reigns would regain the belt at the biggest WWE pay-per-view of 2016, though it’s far from a guarantee.

Reigns had close to even odds to beat Brock Lesnar for the WWE World Heavyweight Championship at WrestleMania 31, but Seth Rollins cashed in his Money in the Bank briefcase and won what turned into a triple threat match. Earlier in the night, Sting lost to Triple H, even though the former face of WCW had the exact same odds that Reigns has on Sunday.

Two years ago, Lesnar defeated The Undertaker in maybe the most shocking result in WWE history. The former UFC champion ended the Deadman’s WrestleMania streak at 21 consecutive wins, entering WrestleMania as a +1000 underdog. While John Cena’s win over The Rock at WrestleMania 29 was expected, he was a -350 favorite when he lost to the movie star at WrestleMania 28.

There is no clear favorite in two of the top three matches at WrestleMania 32. The Undertaker is a slight favorite against Shane McMahon, though it wouldn’t be a shock to see Vince McMahon’s son win and take control of “Monday Night Raw.” Dean Ambrose is barely an underdog against Lesnar, and the No Holds Barred stipulation gives him a chance to find a way to win.

The betting odds favor a title change in the Divas Championship match, though Kevin Owens and Kalisto are favored to hold onto the Intercontinental Title and United States Championship, respectively. A member of The Wyatt Family is expected to win the Andre The Giant Memorial Battle Royal.
