Dota 2: MOUZ vs Yellow Submarine (BO3) - The International Europe Closed Qualifier Playoffs

Platform comparison

Active sub-markets

Market context

MOUZ and Yellow Submarine are playing an upper-bracket best-of-three in the Europe closed qualifier for The International, so the market is about whether MOUZ can convert a scheduled playoff edge into a series win rather than a single-map swing. The crowd-implied 0% YES is a useful signal for a programmatic trader because it usually reflects either stale pricing, thin liquidity, or a market that has not yet caught up with live match status; by the time a match is underway, automation should be checking for score feeds, map progression, and whether the fixture has already advanced or closed[1].

Recent comparable meetings point to MOUZ having the stronger head-to-head profile in this pairing. DLTV records a 2-0 MOUZ win over Yellow Submarine on 5 October 2025, while other match-history pages list prior meetings between the teams across regional and European events[7][2][3]. For conditional-order logic, that history matters less than whether the current series is officially a best-of-three and remains live, because one map can still be enough to flip momentum if the match is delayed, abandoned, or completed after the settlement window.

The main catalysts to watch are official bracket updates, stream status, and any change to the scheduled start time, since resolution depends on the match being played and completed within the allowed window. One live match feed showed a June 22 start at 08:00 GMT, which is consistent with the qualifier timing and also implies that a bot should verify whether the series is already in progress before placing any late-entry order[1]. If the fixture is postponed beyond seven days from the scheduled date, or if it ends without a winner, the market resolves 50-50 rather than to either side.
