Polymarket — resolution criteria

This market refers to the Dota 2 Upper Bracket Final match between Daxak Team and Rostik Team in the BetBoom Streamers Battle Playoffs, initially scheduled for September 27, 2026 at 11:00 AM ET. This market will resolve to "Daxak Team" if Daxak Team win the match against Rostik Team. This market will resolve to "Rostik Team" if Rostik Team win the match against Daxak Team. If the match is canceled (not played at all) or ends in a tie, this market will resolve to 50-50. If the match is postponed, it must be rescheduled to a start time on or before October 11, 2026 at 11:59 PM ET (14 calendar days after the originally scheduled start of September 27, 2026 at 11:00 AM ET). If, by that deadline, the most recently announced rescheduled start time is on or before the deadline, this market resolves based on the result of the match as played. Otherwise, this market resolves 50-50, regardless of whether the match is subsequently played. If the match begins but is not completed, and one team wins due to the opponent's forfeiture, disqualification, or walkover, this market will resolve to the team who wins. If the match ends in a forfeit, disqualification, or walkover (team withdraws before the start and the other wins automatically), this market will resolve to 50-50. The resolution source for this market will be official information from https://www.dotabuff.com. However, if https://www.dotabuff.com has not published final results within 2 hours after the event’s conclusion, a consensus of credible reporting may be used instead including video evidence. In cases where a team’s listed name includes minor discrepancies from the resolution source, this market will resolve based on the underlying real-world match rather than exact name matching. Recognizable abbreviations, alternate or erroneous spellings, sponsor tags, affiliate or academy designations, regional identifiers, and minor formatting differences will be treated as referring to the same team, provided the intended team can be clearly and uniquely identified within the relevant competition. If a listed team name has no reasonable connection to any participating team, or if it matches or could reasonably refer to another team in the same competition such that the intended team cannot be unambiguously determined, this market will resolve 50-50.
