BetOnline customers can now place wagers on the SummerSlam 2021 main event.
As of today, the sportsbook lists the current WWE Universal Champion, Roman Reigns, a -500 favourite. His challenger - John Cena - is a +300 underdog.
This is the second SummerSlam market to be released following the publication of odds for the WWE Raw Women's Championship triple threat match.
When it first went live, BetOnline's market listed the WWE Raw Women's Champion, Nikki A.S.H, as a -115 favourite over Rhea Ripley and former champ, Charlotte Flair. Since then, both Nikki A.S.H. and Charlotte Flair's odds have shortened with the titleholder now into -125 and Flair dipping from +175 into +150.
Ripley has moved from +150 second-favourite to +250.
