This market will resolve to "Yes" if Team Vitality wins the ESL Grand Slam at IEM Rio 2026. Otherwise, this market will resolve to "No". For the purpose of this market, "winning the ESL Grand Slam" requires Team Vitality to: win the IEM Rio 2026 tournament, and have that victory serve as the fourth qualifying win of the ESL Grand Slam Season VI within the ten consecutive eligible event window. If IEM Rio 2026 is cancelled, postponed such that a winner is not declared by May 3, 2026, 11:59 PM ET, or is downgraded prior to the event start, this market resolves "No". If the event is downgraded after it has concluded, it will still qualify for the purpose of this market. The primary resolution source for this market will be official information from ESL (https://esl.com/grandslam/). However, a consensus of credible reporting (e.g., Liquipedia at https://liquipedia.net/counterstrike) may also be used.
