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

Platform comparison

Active sub-markets

Market context

Tundra Esports face Aurora in a best-of-one group stage fixture at BLAST Slam on 26 May, with the match scheduled for 6:20 AM ET. The 90% crowd probability reflects Tundra's standing as one of the Dota 2 circuit's most consistent top-tier organisations, whilst Aurora remains a considerably lower-ranked opponent. No material roster changes or injury announcements have emerged in the past 48 hours affecting either side's participation.

Tundra's recent form provides the primary anchor for the implied odds. The organisation has maintained a winning record against tier-two and emerging regional squads throughout 2025, with only elite-level opponents consistently troubling them in group-stage environments. Aurora, by contrast, has competed primarily in secondary regional circuits and qualifiers, lacking the tournament infrastructure and scrim density that characterises Tundra's preparation. Historical matchups between established top-eight teams and Aurora-tier opponents in BLAST events have favoured the higher-ranked side in roughly 85–92% of single-game encounters.

The settlement window closes at 16:20 UTC on 26 May, allowing a ten-hour buffer beyond the scheduled start time. Traders should monitor BLAST's official schedule for any rescheduling announcements, which occasionally occur within 24 hours of group-stage fixtures due to broadcast logistics or technical issues. Forfeit risk remains minimal given both organisations' professional standing, though the best-of-one format eliminates the possibility of a series reset if technical problems interrupt play mid-game.

Methodology

We track Dota 2: Tundra Esports 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.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
