IEM Cologne Major 2026 is the fifth Counter-Strike 2 Major Championship, organised by ESL with Valve sponsorship. The tournament runs from June 2 through June 21, 2026, with the playoff stage held at the LANXESS Arena in Cologne, Germany — one of Europe's largest indoor venues and a long-standing home of competitive Counter-Strike. Thirty-two teams compete for a $1,250,000 USD prize pool, distributed across an Opening Stage (32 teams, Swiss system), an Elimination Stage (16 teams, Swiss system), and the Playoffs (8 teams, single-elimination with every match a best-of-three). Stage 3 of the event uses no best-of-one matches, a format refinement introduced for this Major.

As a CS2 Major, Cologne 2026 offers more than the prize money: it determines invitations to the next Major cycle, reshuffles the Valve Regional Standings that decide future seedings, and is the most-watched competitive Counter-Strike event of the year. For Israel fans, watching xertioN at this stage is the highest-profile international platform for Israel's Counter-Strike scene in 2026.
