WWE Extreme Rules is tonight, and if the early odds are any indication, it appears as if the end of the show will largely be the same as the status quo.

Roman Reigns and AJ Styles have been battling for the last six weeks over the WWE World Heavyweight Championship, and Reigns is a heavy favorite to retain. Often portrayed as an underdog on WWE television, Reigns looks to be a lock to defeat the former TNA, NWA and IWGP Heavyweight champion.

As of the time of publication, the biggest favorite on the show is Dean Ambrose, who is predicted to defeat Chris Jericho in their 'Asylum Match.' Reigns isn't far behind on his betting lines, however. Rusev is also favored to regain the United States championship from Kalisto.

All of the matches are considered pretty wide odds, and there was no line set for the Karl Anderson & Luke Gallows vs. The Usos match.

The way the betting lines work is if you bet on the favorite (Reigns at -600 for example), 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.

You can see the current betting odds below. We'll update any major changes throughout the afternoon.
