The AEW Women's World Championship match for AEW All In London 2026 is set in stone following the events of the July 29 episode of "AEW Dynamite," where champion Willow Nightingale signed the contract to face Mercedes Mone at the company's biggest show of the year. On the latest edition of "Wrestling Observer Radio," Bryan Alvarez reported that the match between Mone and Nightingale was always the plan, just with the roles reversed. "The original [plan for] Wembley was for Mercedes, as champion, versus Willow. Mone and Nightingale have faced each other three times in the last three years, with Nightingale picking up the win on two occasions while Mone has one win under her belt. However, only two of their three previous bouts have taken place in AEW, making this the rubber match within the confines of the AEW realm.
