WWE Payback is tonight, as it's the first pay-per-view of Shane McMahon's era as an on-screen authority figure. The early odds have been released and may give an indication on who will end up winning the matches.

Roman Reigns, Charlotte, The Miz and Kalisto are all expected to retain their championships, based on the odds. Reigns is currently the second biggest favorite on the show, behind Dean Ambrose, as he's a -600 favorite over the popular AJ Styles.

The two closest calls on the card involve recent NXT call-ups. Enzo Amore & Big Cass will be taking on the Vaudevillains in the finals of the WWE Tag Team Tournament, and the brash New Yorkers are slight favorites. Also, Baron Corbin is listed just edging Dolph Ziggler.

The way the betting lines work is if you bet on the favorite (Reigns at -600), you'd have to bet $600 to earn $100 on his win. If you take the underdog (Styles at +400) you would earn $400 from a $100 bet if Styles were to win.
