Trader consensus crowns Team Vitality as overwhelming favorite at 61.5% implied probability for the BLAST Open Rotterdam 2026 winner, fueled by their sustained HLTV #1 ranking, ZywOo-led firepower, and recent triumphs like IEM Cologne victory and consistent BLAST playoff runs. Parivision's 9.8% stake reflects their explosive rise with young talent and upsets over tier-1 foes in Shanghai Major qualifiers, while Team Spirit (8.5%) holds strong post-Tianjin Major title via donk's aggression. Natus Vincere (7.2%) gains from b1t's return stabilizing the roster amid w0nderful's emergence, but Furia (5.5%) and Falcons (4.5%) lag on inconsistent LAN form and regional depth issues. Odds capture crowd wisdom on form trajectories ahead of Rotterdam's neutral venue.
