Market context

Team Spirit face Xtreme Gaming in a best-of-one group stage match at the BLAST Slam tournament on 28 May, with the fixture scheduled for 8:40 AM ET. The 0% implied probability reflects either a data lag or genuine uncertainty about whether this particular matchup will proceed as scheduled, given that BLAST Slam involves multiple regions and fixture congestion is common in May's esports calendar.

Team Spirit have been the stronger outfit historically, ranking consistently in the top tier of CIS and international Dota 2 competition, whilst Xtreme Gaming represent the Chinese region and have shown variable form across recent qualifiers. In group stage formats, seeding and bracket positioning often determine which teams face one another; if this match is genuinely scheduled, Spirit would be favoured based on recent LAN placements and roster stability. However, group stage volatility—particularly in best-of-one formats—means upsets occur at roughly 25–35% frequency depending on the skill gap, making any extreme probability suspect.

Traders should monitor BLAST's official schedule updates through 27 May, as postponements or bracket reshuffles happen frequently when tournaments run across multiple regions with staggered start times. Confirmation of both teams' participation and final fixture timing should arrive 24–48 hours before the scheduled start. The settlement window closes at 18:30 UTC on 28 May, allowing a 10-hour window for the match to complete; delays beyond 7 days trigger a 50-50 resolution, a safeguard worth tracking if regional internet or visa issues emerge.

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.
