The event, currently titled IEM Rio, would be held Oct. 31 to Nov. 13, and would mark ESL's return to Major organizing after the last two Majors were hosted by StarLadder and PGL. It would also be the fulfillment of a long-gestating plan for the company, which had previously attempted to host an ESL One: Rio Major in May 2020. The COVID-19 pandemic forced that event's postponement and eventual cancellation.
ESL announced the IEM Rio Major was being considered by Valve for 2022 in September 2021. The venue for the event's Champions Stage has yet to be determined. The cancelled 2020 version of the event was set to take place at the Jeunesse Arena, an indoor multi-purpose arena that had previously played host to the 2017 League of Legends Mid-Season Invitational and the 2018 Rainbow Six Siege Season 8 Pro League finals.
Should it come together, the IEM Rio Major would be the second of two CS Majors for 2022. The first, scheduled for May 9-22, has yet have its organizer publicly determined.
