How thin is the top of the ladder?

Name: How thin is the top of the ladder?
Creator: K Culture Wire

Every ranked ladder has a top tier and a tier under it. The distance between them says how steep the climb is at the very top — and it is not the same distance everywhere. Collected 2026-08-06 at 22:00 KST.

Korea’s top 300 barely beat the 700 below them

Korea — gap between tiers0.45 ptChallenger 53.65% against Grandmaster 53.2%. The narrowest of the six regions.

Vietnam — the widest2.04 pt55.46% against 53.42% — more than four times Korea’s gap between the same two tiers.

All six, narrowest gap first

Region	Gap	Challenger win %	Grandmaster win %	Players (C / GM)	Median LP gap	Games each (C / GM)
Korea	0.45 pt	53.65%	53.2%	300 / 700	509	770 / 684
Europe West	1.00 pt	54.95%	53.95%	300 / 700	618	921 / 803
Japan	1.68 pt	55.5%	53.82%	50 / 100	484	465 / 467
Southeast Asia	1.83 pt	54.43%	52.6%	300 / 700	484	410 / 396
North America	1.94 pt	55.16%	53.22%	302 / 718	485	659 / 624
Vietnam	2.04 pt	55.46%	53.42%	300 / 700	607	601 / 628

A tier’s win rate is set by the opponents it draws, not by the tier itself. A narrow gap means the players just below the top take nearly as many games off the field as the players at the top do — which is what a deep player base looks like from the inside. The same argument, one tier up →

The gap, every day we have measured

Percentage points. 4 days — this is not a trend, it is a check that the ordering holds.

Date	Korea	Europe West	North America	Vietnam	Japan	Southeast Asia
2026-08-02	0.46	1.14	1.71	2.04	1.53	2
2026-08-03	0.58	1.08	1.75	2.15	1.34	1.93
2026-08-04	0.61	0.98	1.8	2.06	1.52	1.92
2026-08-06	0.45	1	1.94	2.04	1.68	1.83

Korea is narrowest on every one of the 4 days, and the ordering of all six does not change. 2026-08-05 is missing — the collection key expired and a ladder cannot be reconstructed afterwards, so that day is simply gone rather than interpolated.

What we wrote from this data

Korea's top League players are not the ones grinding hardest. Europe's are.
Europe West's challengers average 921 ranked games to Korea's 770 and Southeast Asia's 410. In five of six regions you play more to reach the top tier. In Vietnam you play less, on all four days measured.

Korean challengers win less than any other region's. That is what a deep ladder looks like.
Korea's top 300 League of Legends players win 53.65% of their ranked games — the lowest of six regions, on all four days we have measured. A win rate at the top is set by who you have to play, and in Korea that is everybody else.

Where these numbers come from

Riot Games — Riot Games Developer API — /lol/league/v4/challengerleagues and /grandmasterleagues, queue RANKED_SOLO_5x5. Collected once a day at 22:00 KST.
Japan is a sixth the size. Its challenger tier holds 50 players against roughly 300 elsewhere, and grandmaster 100 against 700. A narrower cut of a smaller population behaves differently, and its figure is printed without being leaned on.
Win rate is over the current ranked split, including games against opponents outside either tier. It is not a challenger-versus-grandmaster figure.
Player identifiers (puuid, summonerId) are intentionally not stored. Distributions only.
Four days is a snapshot. Nothing here says a gap is widening or narrowing. What it says is that the six regions sit in the same order every day we looked.
