Market context

Team Spirit and Xtreme Gaming are scheduled to meet in a best-of-one Dota 2 fixture at the BLAST Slam Group Stage on 28 May at 08:40 ET. The match carries significant implications for both squads' progression through the tournament's group phase, with seeding and advancement stakes dependent on results across the concurrent fixture slate.

The 0% crowd probability reflects Team Spirit's established standing as a top-tier competitive outfit with consistent Major-level performances, whilst Xtreme Gaming operates at a lower tier of professional Dota 2. Historical matchups between teams of this calibre differential typically favour the higher-ranked side by substantial margins, though single-game elimination formats introduce variance absent from longer series. Recent roster stability at Team Spirit contrasts with Xtreme Gaming's more fluid competitive environment, a structural advantage that compounds the skill gap in knockout scenarios.

Traders should monitor BLAST's official fixture confirmations in the week preceding the match, particularly any schedule adjustments that might affect preparation time or player availability. Team Spirit's recent tournament results and any mid-season coaching adjustments warrant tracking through Liquipedia and esports news outlets covering the CIS region. Xtreme Gaming's roster composition and recent qualifier performances will signal whether the squad has undergone meaningful strengthening. The settlement window closes at 18:30 UTC on 28 May, allowing approximately ten hours post-scheduled start time for completion; delays extending beyond 7 days without resolution trigger a 50-50 split.

Methodology

We track Dota 2: Team Spirit vs Xtreme Gaming (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.
