The most popular esports games, by the numbers
Updated · Published · by KashRock
"Most popular" depends on the metric — peak concurrent viewers for one match, total hours watched across a tournament, or prize money on the table. Here's how the biggest titles compare on each, and what live data is available for each one.
| Rank | Title | Peak concurrent viewers | Other headline number |
|---|---|---|---|
| 1 | League of Legends | ~6.75M (Worlds 2025 final) | 136M+ hours watched (Worlds 2025) |
| 2 | Mobile Legends: Bang Bang | ~5.68M (M7 World Championship final) | — |
| 3 | CS2 | ~2.75M (IEM Cologne 2026 Major) | — |
| 4 | Dota 2 | ~1.79M (The International 2025) | $1.6M base prize pool (The International 2026) |
| 5 | Valorant | ~1.47M (Champions 2025 final) | — |
By peak concurrent viewers
League of Legends still holds the largest audience of any esport: the Worlds 2025 grand final peaked at roughly 6.75 million concurrent viewers. Mobile Legends: Bang Bang's M7 World Championship grand final followed at about 5.68 million, the largest single-match audience of its cycle. CS2's IEM Cologne 2026 Major set a new all-time record for the title at roughly 2.75 million peak, Dota 2's The International 2025 reached about 1.79 million, and Valorant Champions 2025's final drew about 1.47 million — the third-highest peak in VCT history.
Two flagship events are live on the calendar right now: Valorant Champions 2026 runs through October 18, 2026, and League of Legends Worlds 2026 runs October 15 – November 14, 2026. Both will reset this ranking if they beat the peaks above — we update this page as each stage closes.
League of Legends — the largest audience in esports
The Worlds 2025 grand final between T1 and KT Rolster peaked at roughly 6.75 million concurrent viewers — the second-most-watched LoL match on record, just behind Worlds 2024's 6.86 million. The tournament logged over 136 million hours watched across nearly 90 hours of airtime, averaged about 1.53 million concurrent viewers, and set a new YouTube record for LoL esports at 3.77 million peak live viewers. Full breakdown in League of Legends viewership.
Mobile Legends: Bang Bang — the mobile giant
MLBB's M7 World Championship grand final peaked at about 5.68 million concurrent viewers — the largest audience ever for a mobile esport, driven almost entirely by Southeast Asian audiences. Outside LoL, it is the biggest title on earth by peak viewers.
CS2 — the strongest tactical FPS
IEM Cologne 2026 set CS2's all-time record at roughly 2.75 million peak viewers. CS2 also leads on event density — Majors, IEM, BLAST, PGL and ESL circuits run near-continuously, which is why it's the deepest player-props market KashRock covers.
Dota 2 and Valorant — the next tier
Dota 2's The International 2025 peaked at about 1.79 million concurrent viewers. Valorant Champions 2025's final drew roughly 1.47 million — the third-highest peak in VCT history — and Champions 2026 is running now through October 18.
Worlds 2026 — tracking now
Worlds 2026 (October 15 – November 14, 2026) is the most-watched event on the calendar every year it runs. Worlds 2024 holds the LoL record at 6.86 million peak viewers; Worlds 2025 came within reach at 6.75 million. If the 2026 final clears either figure, League of Legends widens its lead at the top of this table again.
The match-level data behind any live tracker — status, scores, player stats — is on the League of Legends API.
By hours watched
League of Legends still leads most years on total hours watched — Worlds 2025 logged over 136 million hours across nearly 90 hours of airtime. A tournament that runs for weeks accumulates more total watch time than a single-day grand final, even one with a higher single-match peak.
By prize pool
The Esports World Cup 2026 carried a $75M total prize pool spread across 24 games — the largest esports event ever staged. Individual tournament totals move year to year; Dota 2's The International 2026 base pool sat at $1.6M before crowdfunded additions.
