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

Platform comparison

Market context

Nigma Galaxy defeated Yellow Submarine 2–1 in the Lower Bracket Semifinal 1 of The International 2026 Europe Closed Qualifier Playoffs on 28 June, securing their path to the next stage[1]. The match, a Best of 3, saw Nigma Galaxy (world ranking 15) overcome Yellow Submarine (world ranking 23) in a contest that concluded at 14:50 ET[1]. This result validates the 100% YES crowd-implied probability that Nigma Galaxy would win, as the team delivered the required outcome without cancellation or tie.

Historically, qualifier matches between teams ranked 15 and 23 in Dota 2 favour the higher-ranked side by roughly 70–75% in decimal odds, though implied probability platforms often compress this to 85–90% due to fee structures and liquidity[4]. On Polymarket, this market resolved at 100% implied probability with no KYC, whereas Kalshi would require identity verification and offer decimal odds around 1.05, reflecting a 5% edge for the house. Betfair and Smarkets, by contrast, list decimal odds of 1.02–1.03, embedding a 2–3% fee that reduces trader payout compared to Polymarket’s zero-fee model.

Traders should monitor the official TI 2026 schedule for Nigma Galaxy’s next Lower Bracket match, which is expected within 48 hours of this result[3]. No new announcements have altered the team’s status, and both squads remain active with no roster changes reported since the match[5]. The settlement window ends 28 June 2026 at 20:50 UTC, confirming the event has already concluded and the market is settled[1].
