What is the Mid-Season Invitational (MSI)?
The Mid-Season Invitational (MSI) is an annual international League of Legends tournament that has been held since 2015. Riot Games organises it, and top teams from around the world compete for the title. It is called the Mid-Season Invitational because it is usually held in the middle of the League of Legends season. MSI 2023 took place at the Copper Box Arena in London. The tournament has been hosted in different parts of the world, including Europe, South America and Asia.
MSI 2023 format and teams
MSI 2023 had two stages, the Play-In Stage and the Bracket Stage, and the winner was crowned Mid-Season Invitational champion.
Participating teams
MSI 2023 featured 13 teams from around the globe. There were two teams each from the top four leagues: LCK (Korea), LPL (China), LEC (Europe) and LCS (North America). The other leagues sent one team each: LLA (Latin America), CBLOL (Brazil), PCS (Taiwan, Hong Kong, Macao, Southeast Asia and Oceania), VCS (Vietnam) and LJL (Japan). Those teams started in the Play-In Stage.

Eight teams played the Bracket Stage in a double elimination, best-of-five bracket: the three Play-In winners, plus LEC #1, LCS #1, LPL #1, LCK #1 and LCK #2.
