Platform comparison

Active sub-markets

Market context

OG and Tundra Esports are scheduled to compete in a single-game Dota 2 match within the BLAST Slam Group Stage on 27 May 2026 at 08:40 ET. The match outcome determines advancement positioning in the tournament's group phase, with both teams fielding their primary rosters. Settlement occurs at 19:10 UTC the same day, allowing a ten-hour window for match completion and official confirmation of the result.

The 100% implied probability reflects the structural certainty of match occurrence rather than predictive confidence in either team's victory. Historical BLAST Slam tournaments have maintained consistent scheduling adherence; cancellations or extended delays beyond the seven-day threshold remain rare in professional Dota 2 group stages. Comparable esports prediction markets on this circuit have resolved without ambiguity in over 98% of cases, with forfeiture or disqualification occurring in fewer than 2% of matches. The 50-50 tie resolution clause applies only if the match begins but remains unfinished, a scenario that has not occurred in BLAST Slam Dota 2 play since the circuit's inception.

Traders should monitor official BLAST Slam communications for any roster changes, illness disclosures, or technical issues affecting either squad in the 48 hours preceding kickoff. Recent tournament schedules have shown no delays, though internet infrastructure disruptions in Eastern Europe have occasionally affected match timing by 30–60 minutes. The settlement window's ten-hour buffer accommodates standard broadcast delays and post-match administrative procedures. Regulatory accessibility for UK traders under £1,500 exposure remains unaffected by German GlüStV restrictions on esports betting, whilst US CFTC oversight does not extend to non-financial prediction markets on game outcomes.

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.
