2018 League of Legends World Championship

The 2018 League of Legends World Championship was an esports tournament for the multiplayer online battle arena video game League of Legends. It was the eighth iteration of the League of Legends World Championship, an annual international tournament organized by the game's developer, Riot Games. It was held from October 1 to November 3, 2018, in cities across South Korea. Twenty four teams qualified for the tournament based on their placement in regional circuits such as those in China, South Korea, Europe, and North America, with twelve of those teams having to reach the group stage via a play-in round.^[2] The tournament became known for its very surprising results, numerous upsets, and has often been considered the most unpredictable worlds in League of Legends' history.^[3][4][5] The tournament also became the most watched esports event in history, reaching a peak of over 200 million concurrent viewers during the finals. It surpassed the viewership of the 2017 League of Legends World Championship, as well as the peak viewership of numerous worldwide sporting events including the Super Bowl.^[6][7]

The tournament's opening ceremony received significant attention, with over 90 million concurrent viewers tuning in for the performance. A virtual K-pop group named K/DA was unveiled by Riot Games during the ceremony, with Soyeon and Miyeon from (G)I-dle, Madison Beer and Jaira Burns representing the group as its human counterpart and in the live performance of the finals. K/DA topped global music charts after the initial release of their debut song "Pop/Stars", receiving considerable attention online and raking in one of the fastest viewership records for its music video on YouTube. A dance practice video of "Pop/Stars", as popular in the K-pop scene, was also released.^[8][9][10] "RISE" is the tournament's theme song, put together by The Glitch Mob, Mako and The Word Alive. A remix version of "RISE" featuring Bobby from IKON was also released shortly after, with the song being performed on the tournament's finals by all the involved music groups and artists.^[11] The song would be performed again when Korea hosted the tournament for the second time in 2023.

The victory of China's Invictus Gaming over Europe's Fnatic in the tournament's finals marked the first time in League of Legends history that the LPL (China) as a region won the world championship, as well as the first time a non-LCK (Korean) team has won after five consecutive years of prior Korean winners. The final series is also the fastest world championship finals in history at 85 minutes total game time.^[12] Gao “Ning” Zhenning was awarded the MVP of the finals due to his outstanding performance and contributions during the series, marking the first time a jungle position player has won a world championship MVP.^[13][14]

Although the South Korea (LCK) representative, Kingzone DragonX, lost to China's (LPL) representative Royal Never Give Up (LPL) in 2018 Mid-Season Invitational (MSI) Finals, all three teams from South Korea (LCK) started in the Main Group Stage, having won the 2017 Mid-Season Invitational and the previous two World Championships. With the results of 2018 MSI and following their separation from the rest of the Southeast Asian (SEA) region, Vietnam (VCS) had a direct seed into the Main Group Stage for the summer split victor in their region, but unlike the previous year, Vietnam had no additional slots in the Play-In Stage for their summer runner-up team, because of the 24 team limit. The North American (NA LCS) summer split champion team was seeded to Pool 2 due to their performance at the 2018 Mid-Season Invitational.

The group stage was held at the BEXCO Auditorium in Busan from 10 to 17 October, with matches beginning at 17:00 KST (UTC+09:00). Sixteen teams were drawn into four groups of four, with teams from the same region not permitted to be placed in the same group. The stage was played in a double round-robin format, with all matches contested as best-of-one. In cases where teams finished with identical win–loss and head-to-head records, a tiebreaker match was held. The top two teams from each group advanced to the Knockout Stage, while the bottom two were eliminated.

The knock-out stage featured eight teams drawn into a single-elimination bracket. Each first-place team from the group stage was matched against a second-place team from another group, with teams from the same group kept on opposite sides of the bracket to ensure that they could not meet until the final. All matches were played as best-of-five series.
