All In (professional wrestling)

All In is a professional wrestling pay-per-view (PPV) event, currently produced by the American promotion All Elite Wrestling (AEW). The inaugural event was held independently in September 2018 and inspired the creation of AEW a few months later in January 2019. That inaugural event was promoted by members of The Elite, in association with Ring of Honor (ROH), which retained the rights to the event. The Elite would become executive vice presidents of AEW, and the company established a spiritual successor to All In called All Out. After AEW president Tony Khan purchased ROH in March 2022, he obtained the rights to All In and subsequently revived the event in 2023 as an annual PPV for AEW, held in London, England at Wembley Stadium during the United Kingdom's August Bank Holiday weekend.

The inaugural 2018 event, held at the Sears Centre Arena (renamed Now Arena in 2020) in Hoffman Estates, Illinois, was notable for being the first non-WWE or World Championship Wrestling promoted professional wrestling event in the United States to sell 10,000 tickets since 1993. The 2023 event was claimed by AEW officials to have set an all-time wrestling paid attendance record of 81,035, but this was disputed. It would also be AEW's first PPV held in the United Kingdom and in an association football stadium.
