Will Ospreay won the AEW World Championship, defeating Kenny Omega in a brutal main event at the promotion's All In event at Wembley Stadium in London. The victory made Ospreay the first Englishman to win a world title on home soil, capping a rivalry with Omega that dates back to their years together in New Japan Pro-Wrestling and marking one of the biggest moments of his career.

The match was punishing on both sides: Omega opened Ospreay up with a TV monitor and put him through a table, while Ospreay repeatedly answered with his Hidden Blade finisher, a Styles Clash and a Tiger Driver, none of which was enough to end it outright. Omega also landed a clean One-Winged Angel and multiple V Triggers, but Ospreay kept kicking out, and the crowd broke into "This is awesome" chants as both men fought on despite heavy blood loss. Ospreay eventually sealed the win with a final Hidden Blade, becoming visibly emotional as he was crowned champion.
