The event marked the first time a double elimination format would be applied to a League of Legends esports event, as the event was split into two stages, that being the play-in stage and the bracket stage.[2][3]
The tournament was hosted in London, England, from 2 to 21 May 2023. All stages of the tournament were played in the Copper Box Arena.[4]
"Rules (Are Meant to Break)" was the tournament's theme song, put together by Che Lingo.[5]
Royal Never Give Up from China were the two-time defending champions, but failed to qualify for the event after losing to Bilibili Gaming in the 2023 LPL Spring Playoffs.[6]
JD Gaming and Bilibili Gaming, both from China, faced off in the finals, with JD Gaming defeating Bilibili Gaming 3–1 and winning their first MSI title.[7][8]
Format
8 of the 13 teams started from the play-in stage. Three final surviving teams from the play-in stage then proceeded to the bracket stage, where they would meet with the other five teams.[9] For the event, the teams were unable to use champions Yuumi and Milio as both were deemed unsuitable by Riot Games for competitive play at the time.[10]
Play-in stage
All teams were drawn into two groups, with all groups having four teams. Excluding the Last Chance Qualifier (LCQ) match that was a best-of five match, all the other matches of the stage had a best-of-three double elimination format.[9]
Bracket stage
The three surviving teams from previous stage joined the other five teams to compete in the bracket stage. All matches of the bracket stage had a best-of-five double elimination format.[9]
Qualified teams
Four of the nine premier League of Legends leagues had two teams representing them, including the LCK, LPL, LEC and LCS,[11] with both LCK teams will start in the bracket stage due to a team from the region winning the 2022 World Championship. Team from LCL (CIS), TCL (Turkey), LCO (Oceania) have been no longer qualified directly for MSI since 2023. The number of teams taking part in this tournament would be increased from eleven to thirteen.
