This market refers to the Counter-Strike Grand final match between Spirit and MOUZ in the BLAST Open Porto Playoffs, initially scheduled for September 6, 2026 at 10:00 AM ET. This market will resolve to "Over" if Spirit and MOUZ play 5 or more maps in this series. If fewer than 5 maps are played, this market will resolve to "Under". Maps won by forfeit, disqualification, walkover, or default are counted towards the total, provided that the match is completed. If the match is canceled (not played at all for any reason) 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 September 20, 2026 at 11:59 PM ET (14 calendar days after the originally scheduled start of September 6, 2026 at 10:00 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 match forfeiture, disqualification, or walkover, this market will resolve to 50-50. If the match ends due to the clinching map being forfeited this will count as a completed match. The resolution source for this market will be official information from https://hltv.org. However, if https://hltv.org 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.
