Market context

Xtreme Gaming, the Chinese organisation, face Team Yandex in a best-of-one Dota 2 match scheduled for 27 May at 7:30AM ET as part of the BLAST Slam Group Stage. The fixture represents a single-elimination format encounter where only one team advances; the 0% implied probability suggests the market has received minimal liquidity or reflects strong consensus around one outcome, though settlement hinges on match completion within the seven-day window from the scheduled date.

Historical precedent in BLAST Slam tournaments shows Chinese regional representatives like Xtreme Gaming typically command stronger odds against European-based squads, though Team Yandex's participation signals competitive qualification. Comparable group-stage encounters in similar Dota 2 circuits have resolved without incident when both teams fielded full rosters, but cancellations or extended delays remain material risks given geopolitical factors affecting Russian team participation in international tournaments. The 50-50 tie-break clause becomes operative if scheduling slippage extends beyond seven days or if the match begins but fails to conclude with a decisive winner.

Traders monitoring this market should track BLAST's official schedule updates and roster confirmations in the 48 hours preceding the fixture. Programmatic approaches would benefit from conditional order logic tied to match-start confirmation—many prediction market APIs allow settlement-contingent triggers that fire only once match commencement is verified through official broadcast channels or tournament administration feeds. Delays in visa processing or last-minute roster changes have historically affected Russian team participation; monitoring team social media and BLAST's public statements through 26 May provides early warning signals before the settlement window closes.

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.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
