Randy Orton is now the favorite to win this Sunday's Royal Rumble match, according to 5 Dimes. As noted, The Wrestling Observer Newsletter reported this week that unless plans change, Randy Orton is slated to win The Royal Rumble and Bray Wyatt is scheduled to win next month's Elimination Chamber match, setting up an Orton vs. Wyatt WWE Championship match at WrestleMania 33.

The Undertaker is the second favorite at +400, followed by Goldberg and Braun Strowman, who are tied at +550.

A quick note on betting odds, a minus sign indicates the favorite with the following number representing how favored the competitor while the plus sign designated the underdog. In the case of the Rumble match, everyone is an underdog. However, if you were to bet $100 on Orton, you would win $400 if he were to win the Rumble. However, if you were to bet $100 on Heath Slater (+27500), you would win $27,5000 should Slater win the match.

Below are the betting odds for the other title matches with odds on Sunday's show. As of this writing, Charlotte is the only champion favored in their respective match. Please note that the odds often change several times before the show. We will have the final odds on Sunday afternoon when the smart money is in. Thanks as always to our friends at Bet Wrestling.
