CS2 Majors maintain a commanding lead in peak concurrent viewership, with the 2026 IEM Cologne event setting an all-time record near 2.75 million, driven by its established European and Russian audiences, expanded formats, and prestige as Valve's flagship tournaments. VALORANT's top events, including recent Masters and 2025 Champions peaks around 1.47 million, trail significantly despite strong co-streaming and Pacific regional support, as shown in Esports Charts data through mid-2026. This consistent gap across S-tier tactical FPS events underpins the 96.9% implied probability traders assign to no crossover. A lower-peaking Singapore Major or unprecedented VALORANT Champions breakout could theoretically shift the comparison, though historical trends and audience concentration make such reversals unlikely.
