This was WWE's first PPV and livestreaming event held in Indianapolis since Clash of Champions in September 2016, which was at the same arena when it was known as Bankers Life Fieldhouse (renamed in 2021).

On June 20, 2023, however, WWE announced the revival of the event, with the seventh Fastlane scheduled for Saturday, October 7, 2023, at the Gainbridge Fieldhouse in Indianapolis, Indiana, and featured wrestlers from the Raw and SmackDown brand divisions.

This was WWE's first pay-per-view (PPV) and livestreaming event held in Indianapolis since Clash of Champions in September 2016, which was at the same arena when it was formerly known as Bankers Life Fieldhouse (renamed in 2021).

[7] Hours before WrestleMania 39 Night 2 began, CNBC reported via multiple sources that a deal between WWE and Endeavor, the parent company of Ultimate Fighting Championship (UFC) via Zuffa, was imminent.

[8] The sale was confirmed the next day on April 3[9] and was finalized on September 12, with WWE merging with the UFC to become divisions of TKO Group Holdings.

[17] On the September 1 episode of SmackDown, John Cena made his return to WWE, which was his first appearance since Money in the Bank in July.

A contract signing for the match was setup to happen later that night; however, Jimmy and Sikoa brutally attacked Styles backstage.

[14] At SummerSlam, Iyo Sky cashed in her Money in the Bank contract and won the WWE Women's Championship right after Asuka had lost the title in the prior match.

[22] On the September 22 episode of SmackDown, Latino World Order (LWO) members United States Champion Rey Mysterio and Santos Escobar defeated Bobby Lashley's accomplices The Street Profits (Angelo Dawkins and Montez Ford).

[20] The following week, after a United States Championship match between Mysterio and Escobar, The Street Profits came out and attacked the two, which pleased Lashley.

Fellow LWO members Joaquin Wilde and Cruz Del Toro came out to even the odds only for The Street Profits to overpower them.

[16] Two weeks later, it was announced that Bálor and Priest would defend the Undisputed WWE Tag Team Championship against Rhodes and Jey at Fastlane.

[1] Next, the LWO (Rey Mysterio and Santos Escobar, accompanied by Zelina Vega) and a mystery partner faced Bobby Lashley and The Street Profits (Angelo Dawkins and Montez Ford) in a six-man tag team match.

[1] After that, Iyo Sky defended the WWE Women's Championship against Asuka and Charlotte Flair in a triple threat match.

[1] The penultimate match saw John Cena and LA Knight facing The Bloodline (Jimmy Uso and Solo Sikoa, accompanied by Paul Heyman).

[1] In the main event, Seth "Freakin" Rollins defended the World Heavyweight Championship against Shinsuke Nakamura in a Last Man Standing match.

[1] On the following Raw, it was announced that new Undisputed WWE Tag Team Champions Cody Rhodes and Jey Uso would defend the titles against The Judgment Day (Finn Bálor and Damian Priest) in a rematch the following week.

[31] John Cena opened the following episode of SmackDown, however, he was quickly interrupted by The Bloodline (Solo Sikoa and Paul Heyman) with a returning Roman Reigns, who had been on vacation since shortly after SummerSlam.
