Active sub-markets

Market context

LGD Gaming face OG in a best-of-one group stage match at the BLAST Slam on 28 May, with the fixture scheduled for 12:10 PM ET. The 0% implied probability suggests either significant uncertainty about match completion or a technical issue with market pricing, as both teams are established Dota 2 competitors with recent tournament activity. OG, the two-time International champions, have maintained competitive rosters through 2024-2025, whilst LGD Gaming remain a consistent top-tier Chinese representative on the international circuit.

Historical precedent for BLAST Slam Dota 2 fixtures shows matches typically proceed as scheduled unless organisational disruptions occur. Cancellations or extended delays beyond the seven-day resolution window remain uncommon for established tournament formats, though technical issues or player unavailability have occasionally affected group stage scheduling. The current 0% probability reading warrants scrutiny—such extreme valuations often reflect either missing information about team participation or a market liquidity issue rather than genuine certainty about match non-completion.

Traders should monitor BLAST's official announcements for any roster changes, visa complications, or schedule adjustments in the 48 hours preceding the fixture. Recent tournament calendars show both organisations competing actively, reducing the likelihood of withdrawal. The settlement window closes at 20:20 UTC on 28 May, providing an eight-hour buffer after the scheduled start time for match completion. Any announcement regarding team substitutions or technical delays would materially shift pricing from its current extreme position.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.
