IEM Cologne 2026 Major Stage 1 Opening Matches Set

The first games for IEM Cologne 2026 Major Stage 1 are set, and BIG vs Liquid is the match most fans will watch first. June 2 brings a packed CS2 schedule, with every team fighting to avoid an early stumble. Check the full opening match list below.

BIG vs Liquid Headlines the First Matchups

BIG vs Liquid is the match that gives the first round its main spark. It is set for June 2 as the other matches of the first day in Cologne, and the opening round will be played as Bo1s, so there is almost no room for a slow start.

Key details before the server goes live:

• Match: BIG vs Liquid
• Format: Best-of-one
• Liquid players: NAF, EliGE, malbsMd, siuhy, ultimate
• BIG players: tabseN, JDC, faveN, blameF, gr1ks

There is no score, K/D ratio, ADR leader, or MVP yet because the match has not been played. Any numbers right now would be a guess. In a Bo1, one bad pistol round or a rough CT half can decide everything, which makes this opener one of the most interesting matches of the day.

Top-20 Teams Enter Against Global Challengers

Stage 1 features 16 teams, with GamerLegion, B8, and BetBoom as the three top-20 squads in the field. GamerLegion open against NRG, B8 face TYLOO, and BetBoom meet Gaimin Gladiators. Those three matches set the early tone for the European seeds, especially with only eight Stage 2 places available.

The full opening round is set as follows:

The wider field brings a real regional mix: Europe, the Americas, Asia, and Oceania are all represented. MIBR drawing THUNDER dOWNUNDER and SINNERS meeting FlyQuest should give the first day a different flavor from the usual Europe-heavy openers. For Pick’Ems players, this is exactly the kind of day where one upset can ruin a clean sheet before dinner.

June 2 Opener and Stage Format Details

Stage 1 runs from June 2 to June 5 in Cologne, Germany. The stage uses a Swiss format, where advancement and elimination matches are best-of-three, while other matches are best-of-one. Stage 2 keeps the same Bo1 and Bo3 split, while Stage 3 moves fully to best-of-three play.

The stakes are simple: eight teams move on to Stage 2, and eight go home. With the Major running through June 21 and 32 teams in total, the first stage is not a warm-up. It is the first cut, and Cologne rarely gives second chances cheaply.
