WrestleMania is just around the corner, and oddsmakers are setting preliminary odds for the event. The biggest surprise? They expect massive title movement, indicating a potential landscape shift in the WWE.
Champion v. Champion
Roman Reigns is set to take on Brock Lesnar in a title unification match. As dominant as the Beast Incarnate has been, oddsmakers expect him to take the loss here.
Reigns is given -300 odds, or an implied 75% chance of victory. Lesnar is given +225 odds, or an implied 30.8% chance. As things stand, it would be a shock if Lesnar walks out of Mania with a title.

Raw Women's Championship
Becky Lynch has been a dominant force since returning from maternity leave. Oddsmakers expect that to end at Mania with Bianca Belair winning a title at WrestleMania for a second time and avenging her many losses to Lynch over the last 7 months.
Belair is a massive favorite at -400, or an implied 80% chance of victory. Becky Lynch is given +275 odds, or an implied 26.7% chance to retain her title.

Smackdown Women's Championship
This one is easy. The returning force that is Ronda Rousey is the biggest favorite in a title match. The rowdy one will finally get her first WrestleMania title victory by defeating The Queen, at least that's what oddsmakers believe.
Rousey is given -500 odds, or an implied 83.3% chance of victory. Charlotte Flair is given +333 odds, or an implied 23.1% chance to retain her title.

Raw Tag Team Championship
A title retained? Despite the company expected to shake up most of the major titles, the tag team titles are expected to stay home. RK-Bro are the favorites to hold onto their titles.
Randy Orton and Riddle are given -188 odds, or an implied 65.2% chance of victory. Their biggest competition is expected to be the Street Profits who're given +225 odds, or an implied 30.8% chance of victory. The Alpha Academy is an afterthought with +550 odds, or an implied 15.4% chance to pull off the shock upset.

Smackdown Tag Team Championship
The other title that oddsmakers expect to be retained. Oddsmakers believe the Usos will retain their titles and leave The Bloodline standing tall at Mania.
The Usos are given -250 odds, or an implied 71.4% chance to retain their titles. Nakamura and Boogs are given +175 odds, or an implied 36.4% chance to come out on top.

Women's Tag Team Championship
In the tightest title match on the card, oddsmakers expect Sasha Banks and Naomi to win the tag belts. A move that might put more respect and attention on the titles.
Banks and Naomi are given -150 odds, or an implied 60% chance to win the titles. Their biggest competition is expected to be Rhea Ripley and Liv Morgan who've been given +300 odds, or an implied 25% chance of winning. Carmella and Queen Zelina are given +600, or an implied 14.3% chance to retain their titles. Coming up the rear are Natalya and Shayna Baszler who're given +800 odds, or an implied 11.1% chance to pull off the upset.

Quote from OddsChecker spokesman Kyle Newman, "WrestleMania always offers surprises, shocks, and memorable moments. This year, oddsmakers expect that to come from massive changes at the top of both the Men's and Women's title pictures. It could potentially reshape the landscape of the company. If oddsmakers are right, it could be a new day in the WWE."
