Updated SummerSlam 2025 Betting Odds: Heavy Favorites and Potential Upsets – For the first time in WWE history, SummerSlam will be a two-night spectacle—and with nine matches already confirmed, oddsmakers at BetOnline.ag have released their updated betting lines for the stacked card. Eight championship matches are currently set, with betting odds suggesting major shifts in WWE’s title landscape are likely.
Top Title Bouts: Rhodes and Punk Strong Favorites
The top two men’s singles championships are expected to change hands. Cody Rhodes is now a commanding favorite (-400) to dethrone John Cena (+250) for the Undisputed WWE Championship, with his odds improving dramatically from their opening line of -250. The implied probability suggests an 80% chance of victory for the American Nightmare, positioning him to finally secure WWE’s top prize.
Similarly, CM Punk is favored (-275) over Gunther (+185) to win the World Heavyweight Championship, following his hard-earned victory over Bron Breakker to secure the title opportunity. Punk’s odds reflect a 73.3% likelihood of capturing the belt, despite the Austrian champion’s dominant reign since WrestleMania.
Women’s Divisions: Naomi and Cargill Heavily Backed
Naomi is the heaviest favorite on the card at -1000 to retain her Women’s World Championship in a triple threat match against Rhea Ripley (+300) and Iyo Sky (+600). Her implied win probability sits at 83.3%, a steep jump from her initial -500 line.
Over on the SmackDown side, Jade Cargill is poised to make a major statement. She enters her WWE Women’s Championship bout as a -700 favorite over Tiffany Stratton (+400), giving her an 87.5% likelihood of capturing her first WWE title after a dominant Owen Hart Cup victory.
In the Women’s Intercontinental Championship picture, Lyra Valkyria (-400) has overtaken Becky Lynch (+250) as the likely winner. Valkyria opened as a modest favorite but has seen significant line movement, suggesting strong confidence in her to dethrone “The Man.”
Midcard Titles: Styles Favored, Sikoa a Narrow Lean
AJ Styles (-450) is a strong favorite to defeat Dominik Mysterio (+275) for the Intercontinental Championship, with oddsmakers giving him an 81.8% chance of securing his first title since returning to RAW. The odds reflect a lack of confidence in Mysterio’s ability to survive against a veteran like Styles.
For the United States Championship, Solo Sikoa is only a slight favorite (-140) to retain against Jacob Fatu (+100). The narrow line suggests the match could go either way, with Sikoa holding just a 58.3% edge. Fatu’s push within The Bloodline drama could lead to a title change if storylines dictate internal upheaval.
Tag Team Action: Flair & Bliss, Orton & Jelly Roll Heavily Backed
In the Women’s Tag Team Championship match, Alexa Bliss & Charlotte Flair (-600) are heavy favorites to unseat Judgment Day (+350), continuing the trend of major title shakeups. With an 85.7% win probability, the newly formed duo appears poised to bring prestige back to the tag titles.
The celebrity tag match also leans strongly toward the babyfaces. Randy Orton & Jelly Roll (-500) are overwhelming favorites against Drew McIntyre & Logan Paul (+300). The 83.3% probability suggests WWE will lean into feel-good moments, especially in front of a massive SummerSlam crowd.
More to Come: LA Knight, Penta, Vaquer Await Final Card Placement
While nine matches are confirmed, WWE is expected to add more to fill out both nights of SummerSlam. LA Knight, Penta El Zero Miedo, and Stephanie Vaquer are all reportedly in line for matches. Another men’s tag title bout could also be added, and a potential reunion of Rusev and Sheamus remains on the table.
As it stands, SummerSlam is shaping up to be a weekend of sweeping change. With nearly every champion listed as an underdog, WWE may be planning to reset several divisions heading into the fall.
