All In (stylized as ALL IN) was an independent professional wrestling pay-per-view (PPV) event promoted by Cody and The Young Bucks (Matt and Nick Jackson) from the Bullet Club. It took place on September 1, 2018 at the Sears Centre in the Chicago suburb of Hoffman Estates, Illinois. The event aired live on traditional PPV outlets, Fite TV, and Honor Club, and was later made available for on demand viewing on the NJPW World streaming service. The event included Zero Hour, an hour long pre-show that aired on WGN America. The event – while independently produced – featured wrestlers from Ring of Honor (ROH), Consejo Mundial de Lucha Libre (CMLL), New Japan Pro-Wrestling (NJPW), Impact Wrestling, Lucha Libre AAA Worldwide (AAA), and the National Wrestling Alliance (NWA).
The event had eleven matches, with two being on the pre-show. The show’s main event was a six-man tag team match which saw The Golden Elite (Kota Ibushi, Matt and Nick Jackson) defeat Rey Mysterio, Rey Fénix, and Bandido. In the penultimate match, Kazuchika Okada defeated Marty Scurll. On the undercard, Cody defeated Nick Aldis to win the NWA Worlds Heavyweight Championship, Jay Lethal successfully defended the ROH World Championship against Flip Gordon, and the IWGP Heavyweight Champion Kenny Omega defeated Penta El Zero.
The event is 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.
