Dota 2: TEAM VISION vs Team Spirit (BO3) - The International Group Stage

Platform comparison

Market context

Team Spirit and TEAM VISION meet in Round 4 of The International Group Stage on 15 August 2026, a best-of-three fixture scheduled for 1:00 AM ET. The match determines positioning within the group phase, with implications for seeding in subsequent bracket play. Settlement occurs at 11:00 AM ET the same day, allowing a ten-hour window for match completion and result confirmation.

Historical precedent suggests Team Spirit enters as favourites despite the 61% implied probability favouring TEAM VISION. Team Spirit has consistently ranked among the top-four Dota 2 rosters at International tournaments over the past three years, whilst TEAM VISION's qualification pathway and recent LAN performance remain less established. Comparable group-stage matchups involving established versus emerging rosters typically see the established side favoured by 65–75% in similar probability markets, suggesting the current odds may reflect either recent roster changes, scrim results, or updated meta assessments that have shifted perception toward TEAM VISION.

Traders should monitor official The International schedule announcements for any postponement notices, which would extend the settlement window to 29 August 2026. Roster confirmations and last-minute stand-in declarations typically emerge 24–48 hours before matches; conditional orders keyed to such announcements allow programmatic position adjustment. Patch notes released within two weeks of the event can significantly alter hero viability and team preparation timelines. Liquidity patterns often spike 12 hours before match start, offering execution opportunities for larger positions.
