Dota 2: Team Yandex vs Aurora (BO1) - BLAST Slam Group Stage

Active sub-markets

Market context

Team Yandex face Aurora in a best-of-one Dota 2 encounter at the BLAST Slam Group Stage on 28 May, with the match scheduled for 8:40AM ET. The 0% implied probability for a Yandex victory suggests the market has either priced them as heavy underdogs or reflects genuine uncertainty about match participation. Given BLAST's track record of honouring scheduled fixtures, the settlement window closing at 19:00 UTC on the same day allows roughly ten hours for the match to conclude before resolution.

Historical precedent matters here. BLAST Slam tournaments have maintained consistent scheduling across Eastern European and international rosters, though Yandex's participation in major events has been sporadic. Aurora's recent form and roster stability within the CIS region would typically command favouritism, yet the absolute zero probability assigned to Yandex suggests either liquidity constraints on the market or strong consensus that the match may not occur as scheduled. Comparable BO1 fixtures in regional qualifiers have occasionally seen probability swings when roster confirmations arrive late.

Traders should monitor BLAST's official announcements regarding final roster confirmations and any schedule adjustments in the 48 hours before the fixture. Yandex's recent competitive activity and whether they field their standard lineup will be critical; visa or travel complications affecting CIS-based teams have occasionally disrupted BLAST events. The settlement mechanism's 50-50 resolution for cancellations or delays beyond seven days creates a meaningful tail risk that current pricing may not fully reflect, particularly given the early morning ET slot which could compress the resolution window.

Methodology

We track Dota 2: Team Yandex vs Aurora (BO1) - BLAST Slam Group Stage on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
