ESL released Stage 2 viewership numbers for Days 1-2 (June 6-7) of IEM Cologne Major 2026:
Peak and average concurrent
Peak concurrent: 1,840,000 across Twitch and YouTube combined during the Aurora vs paiN opening match on June 6, 14:00-15:30 CEST window. The peak hit during the overtime sequence (15-15 going into OT) when Aurora's back-to-back round wins closed the upset over the 3-0 Stage 1 paiN side.
Stage 2 Days 1-2 average concurrent: 847,000 across the broadcast hours. The average tracks 30% ahead of the 2025 Cologne Stage 2 same-point read (652,000) and 18% ahead of the 2024 Cologne Stage 2 pace.
Second-highest peak: The MongolZ upset
The MongolZ-GamerLegion match on Day 1 peaked at 1,712,000 concurrent — the second-highest broadcast peak of Stage 2 so far. The Mongolian-language regional stream pulled 142,000 peak during the match, doubling the previous Mongolian-CS-broadcast record (the May 28 viewership piece flagged 67k as the previous high on Chinggis Warriors' Stage 1 Cache win).
Regional language streams
Beyond the English main broadcast: Portuguese (Brazilian) stream pulled 218k peak during the Aurora-paiN opener (Brazilian audience watching paiN). Russian stream pulled 167k peak during Spirit-Metizport on Day 1. French stream pulled 142k peak during the Vitality-3DMAX opener. The Russian stream's Stage 2 average concurrent (104k) is 22% ahead of the 2025 Cologne Russian-language pace.
The pace projection
At the +30% Stage 2 pace ahead of 2025 Cologne, the broadcast trajectory puts IEM Cologne Major 2026 on track for the highest aggregate viewership of any CS2 Major to date. The 2024 Cologne previous-high mark sits at 2.61M peak (grand final) — the current Stage 2 trajectory suggests Stage 3 has runway to exceed that, particularly if The MongolZ advance to the Champions bracket and carry the Mongolian-CS-history narrative into the LANXESS arena window.
