**Eastern regions, particularly the LCK, maintain overwhelming structural dominance heading into the League of Legends World Championship 2026.** The last four Summoner’s Cups have gone to Korean teams, and LCK squads (Gen.G, Hanwha Life Esports, T1, Dplus KIA) enter with four slots and the strongest recent international pedigree, including MSI success. LPL representatives (Anyone’s Legend, Bilibili Gaming, Top Esports, Invictus Gaming) add further depth, with four teams also qualified. Western squads from the LEC and LCS (G2 Esports, Team Liquid, Cloud9, Karmine Corp) have recorded occasional upsets against top Eastern sides but remain inconsistent in best-of series and have been routinely eliminated early in recent international events. No late roster changes, standout domestic dominance, or format shifts have altered this pattern. The tournament begins with Play-Ins on October 15, and the implied probabilities across prediction markets align with traders pricing a Western winner as a low-single-digit outcome based on historical results and current regional strength gaps.
