What makes an esports tournament “big”?
A tournament can be considered “big” by several measurable factors:
- Prize pool — total money on the line for teams/players. Big prize pools attract top talent and media attention.
- Viewership — peak concurrent viewers, average viewers, and total hours watched. High viewership means mainstream reach.
- Live audience & venue — stadiums and sold-out arenas signal mainstream adoption.
- Sponsorship & broadcast reach — major brands, global rights deals, and multi-platform streaming.
- Longevity & prestige — tournaments with history and legacy earn cultural significance (think “Worlds” or “The International”).
This guide covers tournaments that lead in one or more of these categories.
1. The International (Dota 2) — the poster child for massive prize pools
Why it’s massive: Valve’s annual Dota 2 championship, The International (TI), became known for unprecedented prize pools by using a crowdfunding model. Players buy in-game items and battle passes; a slice of those sales funds the prize pool, which at its peak created astronomical totals and record payouts to champions.
What matters: Traditionally TI offered the single largest pot in esports — topping tens of millions in some years — making it a headline-grabber for mainstream outlets. Even as prize pool trends fluctuate, TI’s reputation as the highest-stakes Dota 2 event remains. The evolution of the TI prize pool and format has been a major talking point in the industry. Wikipedia
Format & experience: The tournament typically features an extended group stage followed by a main event double-elimination bracket. Matches are long, strategic, and perfect for layered storytelling across storylines: underdog runs, dynasty teams, and meta-defining drafts.
Why fans tune in: Deep strategy, high-stakes gameplay, and community ownership (via crowdfunding) create intense fan engagement, both online and in arenas.
2. League of Legends World Championship (Worlds) — the viewership giant
Why it’s massive: Riot Games has built Worlds into a global spectacle with region-based rivalries, theatrical opening shows, and finals held in major stadiums. It’s notable not just for money but for audience — Worlds has posted some of the largest peak concurrent viewer numbers and total hours watched for any esports event. Recent iterations set new records for peak viewership and total watch-time, proving LoL’s global cultural pull. Esports Insider
Format & experience: A long-format season culminating in Worlds — with play-ins, group stages, and knockout rounds — allows narratives to build over weeks, encouraging sustained engagement and huge weekly streaming numbers.
Marketing & production: Riot invests heavily in production value — cinematic trailers, musical collaborations, and multi-language broadcasting — which helps Worlds cross into mainstream entertainment.
Impact: For advertisers and sponsors, Worlds is prime real estate: millions of live viewers and extended watch-time create an attractive environment for brand activation and regional campaigns.
3. CS:GO Majors & Intel Extreme Masters (IEM Katowice) — FPS spectacle
Why it’s massive: First-person shooters (FPS) like Counter-Strike have an enduring esports scene. Valve-sponsored Majors historically represented the highest competitive level in CS:GO, while tournaments like IEM Katowice have become annual must-watch events with big stadium crowds, nine-figure cumulative global audiences, and professional-level production. IEM Katowice alone regularly hosts six- to seven-figure prize pools and massive live attendance. Esports Charts
Format & experience: Fast-paced matches, best-of-three series, and iconic maps make CS spectacles exciting and accessible. FPS events also excel at cultivating live arena atmospheres — cheers, chants, and visible rivalries.
Lifecycle & community: CS events have strong grassroots and historic communities, ensuring consistent viewership and strong sponsor interest.
4. Fortnite World Cup — mainstream headlines & pop culture crossover
Why it’s massive: Fortnite’s 2019 World Cup generated a staggering amount of mainstream interest: a $30 million prize pool, viral winners, and huge participation in qualifiers (millions of players). The scale and the youth of its winners made global headlines and introduced esports to audiences who had never watched competitive gaming before. TechCrunch
Format & experience: Fortnite combines battle-royale unpredictability with tournament structure. Solo and duo events added variety; streaming-friendly highlights helped the tournament’s viral spread.
Aftereffects: While Epic Games didn’t immediately make the World Cup an annual mainstay with the same scale afterward, the 2019 event proved the crossover potential — bringing in mainstream media, celebrity co-streams, and massive social reach.
5. VALORANT Champions & VCT — Riot’s FPS challenger makes big moves
Why it’s massive: VALORANT’s competitive ecosystem, run by Riot, mirrors the centralized approach Riot used for League. The VALORANT Champions event (the yearly culmination of the VCT season) quickly became one of the biggest tournaments in tactical FPS esports because of Riot’s regional circuits, franchising moves, and broadcast investment.
Format & experience: With structured tour stops (Masters events) and a global Champions event, VALORANT offers high production values and narratives around new rosters and meta shifts. Its cross-region storylines and Riot’s broadcast capabilities helped it gain rapid popularity.
Commercial implications: Riot’s footprint ensures strong sponsorship, franchising money, and integration with broader Riot IP capabilities (music, content, and merchandising).
6. Esports World Cup (Riyadh) — new money, new contenders
Why it’s massive: In recent years, state-level investors and sovereign wealth funds have entered esports. A notable example is the Esports World Cup in Riyadh, an event that in 2025 returned with an eye-popping $70 million prize pool—a record-level allocation that signals a new era of mega-funded spectacles in gaming. This kind of financial muscle reshapes opportunities for organizers, teams, and content creators. Reuters
Format & experience: The tournament expanded to multiple titles and included non-traditional esports like chess in showcase events, demonstrating an ambition to become a multi-genre global festival.
Controversy & conversation: Large public investments into esports attract debate about the sustainability of prize-fueled ecosystems, plus geopolitical questions around sportswashing and cultural diplomacy. These are real industry conversations that impact sponsorship, talent movement, and public perception.
7. Overwatch League (OWL) Grand Finals & Call of Duty League (CDL) Championship
Why they’re massive: Franchised city-based models (OWL and CDL) brought structure and traditional sports-style city rivalries to esports. Grand Finals and Championship weekends attract big live audiences and premium sponsors.
Format & experience: Franchising attempts to stabilize team valuation and revenue. High production values, city rivalries, and a regular season that feeds into a high-stakes playoff weekend make these finals attractive to mainstream advertisers and local fan bases.
Why to watch: These leagues incorporate esports best practices—consistent schedules, storytelling, and local fan engagement—making their finals staple events on the calendar.
8. Rocket League Championship Series (RLCS), EVO (Fighting games), and other genre staples
Why they’re massive: Every genre has marquee events:
- RLCS: High-octane car-soccer with dedicated fanbase and consistent online viewership.
- EVO (Evolution Championship Series): The world’s premier fighting game tournament, with decades of grassroots prestige and multi-game lineups.
- PUBG Mobile Global Championship / Free Fire World Series: Mobile esports events with massive regional audiences, especially in Asia and Latin America.
These tournaments may not always top the monetary charts, but they command enormous regional viewership and passionate communities that keep them culturally relevant.
Comparing tournaments: Prize Pools vs. Viewership vs. Cultural Impact
It’s tempting to say “bigger is better,” but the largest prize pool doesn’t always equal the biggest audience or cultural footprint. Here’s how to think about it:
- Prize pool leaders (e.g., The International) drive headlines and team revenue but often cater to deep-core fans. Wikipedia
- Viewership leaders (e.g., Worlds) deliver scale and global brand exposure, which is valuable to sponsors. Esports Insider
- Crossover events (e.g., Fortnite World Cup) bring in mainstream media coverage and new audiences. TechCrunch
- State-backed mega events (e.g., Riyadh’s Esports World Cup) can redefine budgets and the commercial map of esports, for better or worse. Reuters
How organisers build a “big” tournament
Organisers use several levers to scale an event:
- Prize money & crowdfunding — either centralized funding (sponsors, government backers) or community crowdfunding (battle passes).
- Broadcasting deals & platform partnerships — Twitch, YouTube, regional streaming platforms, and TV deals.
- Production value — cinematic intros, on-stage talent, and augmented-reality overlays.
- Live venue & fan experience — in-person activations, meet-and-greets, secondary stage content.
- Storytelling and narratives — underdog stories, dynasty runs, and player rivalries keep viewers returning.
The economics behind the biggest events
- Ticket sales & on-site spending contribute but are usually a fraction of total revenue.
- Sponsorships & brand partnerships (hardware, energy drinks, telecoms, betting companies) are major revenue drivers.
- Media rights & streaming exclusivity become significant as audiences scale.
- Merchandising & in-game monetization (for titles that control in-game economies) add recurring revenue streams.
High-profile events are costly to produce, but they also open doors to long-term commercial deals that sustain the ecosystem.
For teams and players: why these events matter
- Financial windfall — prize money can make or break an org’s year.
- Sponsorship attraction — success on big stages drives sponsor interest.
- Brand-building — winning or performing well at marquee tournaments shapes legacy.
- Talent pipelines — big tournaments expose new stars to global audiences.
However, the reliance on massive one-off prize pools can create uneven financial risk. That’s why sustainable league models and recurring revenue streams are increasingly attractive.
Regional notes: where “big” looks different
- North America & Europe: strong franchise leagues (OWL, CDL), production houses, and sponsor markets.
- China & Korea: massive viewership for MOBAs and FPS titles; highly professionalized esports organizations.
- Southeast Asia & Latin America: mobile esports and regional grassroots scenes can produce massive local viewership despite lower per-viewer monetization.
- Middle East: large-state investments are creating new mega-events and infrastructure, changing the calendar and prize landscape. Reuters
What to expect in the coming years
- Consolidation of franchise leagues — more predictable revenue for teams but higher barriers to entry.
- More state-backed mega-events — large prize pools and cross-genre festivals will appear, but they’ll spark debate about sustainability and political considerations. Reuters
- Hybrid viewing experiences — AR/VR, second-screen interactivity, and in-game integrations during broadcasts.
- Greater mainstream partnerships — sports teams, broadcasters, and big brands will continue expanding involvement.
- Mobile and regional growth — mobile esports will drive new audiences and localized tournaments with huge concurrent numbers in emerging markets.
