Dota 2: OG vs Tundra Esports (BO1) - BLAST Slam Group Stage

Platform comparison

Active sub-markets

Market context

OG and Tundra Esports are scheduled to face off in a best-of-one Dota 2 match within the BLAST Slam Group Stage on 27 May at 08:40 ET. The conditional tokens on Polymarket currently price this fixture at 100% YES, reflecting the market's assessment that the match will occur and produce a decisive result. On-chain settlement depends on whether a winner emerges before the 7-day grace period expires; if the match is cancelled, delayed beyond that window without completion, or ends in a tie, the contract resolves 50-50 across both conditional token pairs.

OG's recent tournament performances provide the primary historical anchor for reading this probability. The organisation won The International 2018 and 2019, establishing themselves as a stable competitive force, though their results have become inconsistent since 2021. Tundra Esports, by contrast, finished runners-up at The International 2022 and have maintained stronger consistency in regional qualifiers throughout 2024 and early 2025. Direct head-to-head records between these teams show competitive matches without overwhelming dominance by either side, suggesting the underlying event carries genuine uncertainty despite the market's current pricing.

Traders should monitor BLAST's official schedule and social media channels for any postponements or venue changes, particularly given the early morning ET start time which sometimes creates logistical complications for European-based teams. Roster changes or last-minute stand-in announcements could alter competitive balance; both organisations have made mid-season adjustments in previous seasons. The settlement window closes at 19:10 UTC on 27 May, providing a tight 10.5-hour window for match completion and result confirmation on-chain.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

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.
