Which team won the inaugural Overwatch League championship in 2018?

London Spitfire won the inaugural Overwatch League championship in 2018.

The first Grand Finals were played at Barclays Center in New York on 27 and 28 July 2018. London Spitfire defeated Philadelphia Fusion 3–0 in the match series, winning the league’s first championship trophy.

The Spitfire represented London but used a roster largely built from South Korean players, including Profit, Gesture, Birdring and Fury. The league was notable for adopting permanent city-based franchises rather than the temporary team identities common in many earlier esports competitions.

The championship is sometimes confused with the regular-season stage titles awarded during the same season. New York Excelsior won the Stage 3 title, but London Spitfire won the overall inaugural league championship. The Overwatch League later changed its competitive structure and moved away from its original centralized format.
