World ranking of pro League of Legends teams

World ranking

League ratings

A league rating only moves when two regions actually meet, at Worlds, MSI or First Stand.

How it is computed

• Every team starts at 1500. Each game moves both ratings by the standard Elo formula.
• The K factor is 26 domestically and 30 at Worlds, MSI and First Stand: those are the only games that actually compare two regions.
• At each year boundary, ratings regress 10% toward 1500, to account for roster turnover between seasons.
• Blue side wins slightly more often than red, so blue is credited 20 rating points before each game — otherwise that edge would be charged to the team. A 300-point gap means a one-in-ten chance of losing; the chess value of 400 predicts worse here.
• A team that never leaves its region is only calibrated against its neighbours. Its final score therefore blends its own rating with its league's, at 25%. That league rating only moves on inter-region games. Without the blend, international matches are predicted correctly 61.5% of the time; with it, 65.1%.
• Only teams with at least 40 recorded games and recent activity are listed.
• None of these settings were picked by eye. They come from a search run on the 2022–2024 seasons, then checked against 4,334 games from 2025 onwards that the search never saw: the favourite wins 65.0% of them.

Known limits

• A region that rarely plays internationally is poorly calibrated: its teams are rated mostly against each other. Check the "Intl. games" column before comparing across regions.
• A roster change is invisible to the model. Only the yearly regression accounts for it, crudely.
• This is not an official ranking. Riot publishes its own, the Global Power Rankings, which blend a team rating with a league rating the same way — at 20% — for a stated 65% accuracy.
