Will Ospreay captured the AEW World Championship for the first time in his career, defeating Kenny Omega in the main event of AEW All In: London at Wembley Stadium on August 30, 2026. Ospreay fought through a bloody, hard-hitting battle before putting Omega away with the Hidden Blade for the pinfall, becoming the first British-born competitor to win a world title in London.
The show featured several other title changes across its nine championship matches. Mercedes Mone won the AEW Women's World Title by submitting Willow Nightingale, exploiting the hand injury she had inflicted days earlier, while Darby Allin claimed the AEW TNT Championship. Cage and Cope retained their titles, and Andrade El Idolo earned a future world title shot.
The event also marked notable AEW debuts, as former New Day members Kofi Kingston and Austin Creed appeared for the promotion. AEW returned to Wembley Stadium for what it billed as its biggest pay-per-view spectacle of the year.
