All In (professional wrestling)

All In is a professional wrestling pay-per-view (PPV) event, 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 revived the event in 2023 as an annual summer PPV for AEW. All In subsequently became the biggest show of the year for AEW and their flagship/marquee event, similar in comparison to WWE's WrestleMania, and is one of AEW's "Big Five" PPV events, along with All Out, Double or Nothing, Full Gear and Revolution.

The inaugural 2018 event, held at the Sears Centre Arena in Hoffman Estates, Illinois, was notable for being the first non-WWE or World Championship Wrestling (WCW) promoted professional wrestling event in the United States to sell 10,000 tickets since 1993. The 2023 event, which was held at Wembley Stadium in London, England, had an attendance of 72,265, the biggest in AEW's history and one of the biggest in professional wrestling. It would also be AEW's first PPV held in the United Kingdom and in an association football stadium. The 2025 event will be AEW's first PPV event held in a baseball stadium and in the U.S. state of Texas. It will also be the first professional wrestling event to be held at Globe Life Field.
