Day 2 of Stage 1 at IEM Cologne Major 2026 produced two results that read against the May 28 analyst-consensus rankings. Both winning sides sat in the bottom tier of the consensus, both winning matches were on maps the upset side had specifically prepared.
Chinggis Warriors 13-8 SINNERS on Cache
The Chinggis Warriors win is the structural surprise of Stage 1 so far. The Mongolian side sat at 18% mean advancement on the May 28 consensus piece — the lowest of the 16 Stage 1 entries. The Cache pick by SINNERS read as the deciding veto choice in the post-match coverage: SINNERS believed Chinggis Warriors had not prepared the new-geometry Cache, while the Mongolian side had specifically targeted the map during their Mongolian-federation-funded bootcamp.
The match scoreline ran straightforward: 8-4 CT side for Chinggis Warriors, then 5-4 T side to close out 13-8. The standout individual: bLitz with a 1.46 rating, the highest of any Stage 1 Day 2 player. The match also produced the largest Mongolian-language CS broadcast peak on record (67k concurrent, covered in the viewership piece earlier today).
Nemiga 13-9 Imperial on Vertigo
The Nemiga win is the quieter upset of the day. Nemiga sat at 24% mean advancement on the May 28 consensus, against Imperial at 38%. The map pick - Vertigo - was the structural advantage: Nemiga have run more Vertigo competitive matches in 2026 than any other Stage 1 side, and Imperial's pre-Major scrim telemetry showed the team had de-prioritised the map.
The match closed with 1.28 rating from Sjuush and a 1.21 from blackmagic for Nemiga. Imperial's chelo posted 1.07 in defeat, the only Imperial player above 1.0.
What the upsets mean for Day 3
Both Chinggis Warriors and Nemiga now sit in the 1-1 pool with a Day 3 path through to the 2-1 advancement window. If either side wins their Day 3 match, the Stage 2 (Legends) seeding pool gains a first-Major debutant for the first time since IEM Rio 2022. The Day 3 pairings depend on Buchholz tiebreakers but typically place 1-1 underdogs against 1-1 higher-seeds, which would put Chinggis Warriors against either FlyQuest or 3DMAX and Nemiga against either HEROIC or Metizport.
