ESL has confirmed the opening matchups for IEM Rio 2026, and the first round already looks spicy. Big favorites, local pressure, and a fresh rematch should make the start of the event worth watching. Check out the key opening games and see which teams can start Rio with a win.
IEM Rio 2026 starts with 16 teams split into two groups of eight, and every opening series is a best-of-three. Each match will start on April 13th, 2026 at 11:00 (GMT-3) The format is double elimination, so one loss does not end a team’s run, but it does make the path much harder. Three teams from each group move on. Group winners go straight to the semifinals, while second and third place teams head to the quarterfinals.
Group A matches:
Group B matches:
Most anticipated matches with unpredictable results are Natus Vincere versus B8, Team Spirit versus Liquid and Vitality versus RED Canids. Even though NAVI, Vitality and Spirit are favourites in those matchups, you can expect an interesting performance from their opponents.
NAVI against B8 is the obvious head-turner because there is almost no mystery between these teams right now. They met in the BLAST Open Rotterdam opener on March 18, and NAVI took the series 2-1 by winning Mirage 13-9 and Dust2 13-7, even after dropping Ancient 17-19 in overtime. Mihai “iM” Ivan was NAVI’s best performer in that match with a 68-50 K-D, good for a 1.36 K/D ratio, plus a 1.41 rating. That is enough recent evidence to turn this into more than a routine first-round draw.
Spirit against Liquid also comes with receipts. Spirit swept Liquid 2-0 in Rotterdam on March 19, taking Mirage 13-8 and Ancient 13-11. Danil “donk” Kryshkovets was the standout by a wide margin, posting a 55-31 K-D, a 1.77 K/D ratio, 115.2 ADR, and a 1.79 rating. When a star puts up numbers like that, the rematch starts to feel less like a reset and more like unfinished business for the other side.
Vitality versus RED Canids looks lopsided on paper, but it still carries a strong local angle. ESL’s opening announcement noted that the French-led side arrives on a 22-map win streak while chasing the first of three chances this season to complete a second ESL Grand Slam. RED Canids, though, did not back into this spot. The Brazilian side qualified by beating BESTIA 2-1 after losing Nuke 6-13 and then answering on Ancient 13-6 and Inferno 13-7. Kaue “kauez” Kaschuk led that series with a 42-32 K-D, a 1.31 K/D ratio, and a 1.35 rating. In Rio, that kind of underdog form can make even the cleanest draw feel tense.
