As of this writing, 10 matches are officially announced for SummerSlam, but more matches could be added in the build-up on SmackDown. There are also several matches that could include, returns or interference.
All of WWE's major championships are on the line on Saturday night with the exception of the Intercontinental and Women's Tag Team Championships.
It is expected to be a fantastic night of entertainment, and ahead of the show, here are 9 last-minute predictions.
New Champs in WWE! More RIGHT HERE
#9. Nikki A.S.H. retains the RAW Women's Championship at SummerSlam
Nikki A.S.H. shocked the world a few weeks ago when she successfully cashed in the Money in the Bank contract to become RAW Women's Champion for the first time.
A.S.H. has since been placed into a storyline where she needs to prove herself to both Charlotte and Rhea Ripley and this weekend will be her perfect opportunity.
A.S.H. defends her Championship in a triple threat match against both Ripley and Flair and if she's able to pin Charlotte to retain her Championship then she will finally be able to show that she deserves to be Champion.
#8. Rey Mysterio and Dominik win the SmackDown Tag Team Championships at SummerSlam
The Usos were able to defeat Rey Mysterio and Dominik to take the SmackDown Tag Team Championships as part of the Money in the Bank kickoff show last month.
Over the past few weeks, the two teams have clashed several times and now the father and son duo will have a chance to reclaim their titles this weekend at SummerSlam when they are granted their rematch.
A good storyline arc here would be for The Usos to lose their Championships so that Roman Reigns is left in a position where he is the only member of The Bloodline with a title.
Mysterio and Dominik have looked strong in the ring in recent weeks and a loss at SummerSlam would allow The Usos to return to Reigns' side so that the storyline between the family can once again become the focus.
#7. Seth Rollins defeats Edge at SummerSlam
The match between Seth Rollins and Edge has the potential to steal the show at SummerSlam since this story technically began back in 2014.
Rollins used Edge's injured neck to force John Cena to reinstate The Authority and it appears that The Rated R Superstar hasn't forgotten.
Rollins is at the top of his game whilst Edge is still seething from his WrestleMania loss back in April. That being said, it seems more likely that Rollins will be the one to come out on top.
#6. Damian Priest becomes United States Champion at SummerSlam
Damian Priest has been heavily pushed on Monday Night RAW since his arrival earlier this year and could lift his first main roster Championship this weekend at SummerSlam.
Priest takes on Sheamus for the United States Championship and looks the most likely of the two to walk out of Las Vegas with the title.
Sheamus recently suffered a broken nose and has been struggling on RAW ever since, this weekend could be a walk in the park for Priest who has seemingly had Sheamus' number for a number of weeks.
#5. Lilly debuts and helps Alexa Bliss to defeat Eva Marie at SummerSlam
Eva Marie has had some issues with Alexa Bliss' friend Lilly over the past few weeks and now faces off against Alexa Bliss at SummerSlam.
Lilly is currently unable to wrestle Marie herself, which is why Alexa Bliss is taking on Eva Marie tomorrow night, but these circumstances could change.
Chelsea Green recently talked about returning to WWE to portray Lilly as a real person and it's possible that WWE will pull the trigger on this and allow Lilly to debut as a person to help Alexa Bliss at SummerSlam.
It's unclear who Lilly will be as a person, but the company has several interesting options, including Liv Morgan.
#4. Drew McIntyre defeats Jinder Mahal
Jinder Mahal and Drew McIntyre were once teammates as part of 3MB but times have definitely changed as the two men go head to head this weekend.
Mahal and McIntyre have made their feud personal in recent weeks and at SummerSlam The Modern Day Maharaja will be forced to go it alone as Veer and Shanky are banned from ringside.
McIntyre has the advantage since Mahal has become reliant on his friends since his return. It's likely that McIntyre will be the one who walks out with the bragging rights on Saturday night.
#3. RK-Bro become RAW Tag Team Champions at SummerSlam
After weeks of ups and downs, Riddle and Randy Orton will team together this weekend to challenge for the RAW Tag Team Championships this weekend at SummerSlam.
AJ Styles and Omos have held their titles since WrestleMania and will be formidable opponents, but the newly reformed RK-Bro are more than capable of walking out as Champions.
Riddle and Orton have become one of the most entertaining parts of RAW over the past few weeks and adding the Championships to the mix could lead to some interesting new angles.
#2. Bianca Belair retains the SmackDown Women's Championship
Sasha Banks and Bianca Belair main evented night one of WrestleMania in April and now the rematch will take place on Saturday night at SummerSlam.
The Boss has already proven she can't be trusted after returning to SmackDown a few weeks ago and stabbing Belair in the back following their tag team match.
This weekend The EST of WWE knows that there are no allies and she should be able to easily overcome The Boss much like she did at WrestleMania.
#1. Goldberg's son helps him to become WWE Champion at SummerSlam
Goldberg takes on Bobby Lashley tomorrow night at SummerSlam and could walk out of Las Vegas with the WWE Championship.
Goldberg recently noted that he has two matches left on his current WWE deal and could defend the WWE Championship in his next outing if he's victorious tomorrow night. Lashley has been pushed strong over the past few months, but it would be quite a shock if Goldberg's son helped him overcome Lashley and become WWE Champion.
