IEM Rio 2026 starts today at Farmasi Arena in Rio de Janeiro. Sixteen teams, a $1,000,000 total purse ($300K in player share, $700K in club share), and one question nobody can seriously answer with anything other than “Vitality.”
CS2 is back in Brazil for the first time since 2024, and the field is absurdly stacked. The group stage runs April 13 to 15 in closed studios, with playoffs moving to a sold-out arena from April 17 through 19. Format is ESL’s double-elimination groups into a six-team single-elimination bracket, Grand Final Bo5. Last year of this structure before ESL shifts to eight-team playoffs in 2027.
Vitality Hunt a Second ESL Grand Slam in Rio
The numbers around this Vitality roster have stopped making sense. They arrive on a 22-map win streak, the longest active run in professional Counter-Strike and one that trails only NiP’s legendary 87-0 in the all-time record books. Their last three trophies came at IEM Kraków, PGL Cluj-Napoca, and BLAST Open Rotterdam, where they swept NaVi 3-0 in the final barely two weeks ago. Robin “ropz” Kool claimed MVP in Rotterdam; ZywOo was nearly untouchable in the Kraków Grand Final against FURIA, posting one of the highest individual ratings in a Bo5 this season.
Rio is Vitality’s first of three shots to complete a second consecutive ESL Grand Slam. No team has ever done that. A win here puts them one title away from the $1,000,000 Grand Slam bonus and a place in a conversation reserved for prime Astralis. Their opener against RED Canids should be routine. Everything after that will not be.
Groups and Opening Day Matchups
Both groups look like they were drawn by someone who hates underdogs.
Group A
| Match | Team 1 | Team 2 |
| A1 | Vitality | RED Canids |
| A2 | Gentle Mates | G2 |
| A3 | Spirit | Liquid |
| A4 | 3DMAX | Falcons |
Group B
| Match | Team 1 | Team 2 |
| B1 | B8 | NaVi |
| B2 | Legacy | MOUZ |
| B3 | FURIA | Passion UA |
| B4 | Aurora | HOTU |
Group A is a meat grinder. Three of the world’s current top four are in the same bracket. Spirit vs Liquid has become a recurring fixture this season, and 3DMAX vs Falcons has every ingredient for a chaotic, unpredictable series.
Group B rotates around NaVi, ranked No. 2 globally in HLTV’s April Valve rankings. Their opener against B8 is a rematch from BLAST Open Rotterdam. FURIA face Passion UA with full home-crowd energy behind them, while Legacy and MOUZ collide in a match that could define both teams’ tournament arcs.
Key Absences That Change the Picture
Two pre-tournament disruptions have already reshaped expectations.
G2 are without huNter-. Their IGL suffered a cracked bone and stretched ligaments in his foot, ruling him out entirely. Academy player Vilius “tAk” Keserauskas gets his first Tier 1 LAN, SunPayus takes over calling duties, and NertZ assists. G2 just won Stake Ranked Episode 1 with their newly integrated lineup, but losing their shotcaller in a group with Vitality, Spirit, and Falcons is brutal timing. They open against Gentle Mates, and anything less than a clean win will make this Group A bracket feel even more claustrophobic.
Team Spirit travel without head coach hally, who is stepping away due to health issues. Academy coach S0tF1k, the man who developed donk and zont1x before their promotion to the main roster, will guide the team. Spirit’s 2026 has been shaky at best, with a group-stage exit at Rotterdam still fresh. Without hally’s mid-round adjustments, this Spirit side looks like a team that could beat anyone on raw talent and lose to anyone on structure.
What to Watch
Vitality’s streak. If they go flawless through the entire bracket, they add 11 maps to the current 22. That would put them in range of the longest Big Event map streaks in CS history. Every Vitality server is appointment viewing right now.
FURIA at home. The IEM Rio crowd is one of the most overwhelming forces in esports, and FURIA, RED Canids, and Legacy all play on day one. FURIA swept Vitality 3-0 to win IEM Chengdu 2025 but have looked miles off that level for most of 2026. A hostile Farmasi Arena has a way of rewriting form guides, though. If there is a team that can ride crowd energy into an upset, it is this one.
The Cologne Major shadow. Invites are locked, but teams are still playing for VRS points, momentum, and seeding heading into June. For MOUZ, Falcons, and Spirit, a strong Rio run matters less for the trophy and more for proving they belong in the elite conversation at the Major.
G2 without huNter-. tAk averaged a 1.11 rating across 18 months on G2 Ares. Solid at academy level. Tier 1 LAN is a different species. How fast G2 adapt their system around SunPayus’s calling decides whether they survive Group A or go home before the fans even enter the building.
First maps go live today. The Cologne Major is two months away. For 16 teams in Rio, the clock starts now.
