Counter-Strike dominated Twitch viewership in 2025, cementing itself as the most-watched esports title of the year with overwhelming numbers. Meanwhile, League of Legends secured the silver medal but shined with the highest concurrent peak in history during Worlds. However, the biggest surprise on the list was the unexpected entry of Rainbow Six Siege into the Top 5, knocking out heavy competitors that many took for granted.
According to the latest data from Esports Charts, the competitive scene remains concentrated on veteran titles that set the pace of the global market. Moreover, the gap between the top tier and the fifth place is still abysmal, with a distance exceeding 150 million hours watched. That’s why Ubisoft’s achievement with Siege takes on an underdog dimension within the platform.
The 5 most-watched esports on Twitch in 2025
- 1. Counter-Strike: 372 million hours watched
- 2. League of Legends: 307 million hours watched
- 3. Dota 2: 213 million hours watched
- 4. Valorant: 185 million hours watched
- 5. Rainbow Six Siege: 34.76 million hours watched
Records and what to expect in 2026
Although CS leads in total broadcast time, LoL Worlds 2025 was the biggest single event of the year, reaching an impressive peak of 166 million concurrent viewers. Riding that success, Ubisoft is already gearing up for the Six Invitational, starting this Monday, February 2, 2026. The company plans to distribute exclusive rewards via Twitch Drops throughout every stage of the tournament to try to hold its spot in the rankings.
As a result, the 2026 scene promises to be even more competitive with the arrival of new competitions like the Esports Nations Cup. The question remains whether Rainbow Six can hold its place at the top or if other titles will strike back by the end of December.
