Market context

Team Spirit face Team Yandex in a best-of-one group stage match at the BLAST Slam tournament, scheduled for 26 May at 06:20 ET. The current crowd-implied probability stands at 100% for Team Spirit, reflecting strong market confidence in their victory. Settlement closes at 16:30 UTC the same day, allowing roughly ten hours for the match to conclude before resolution.

Team Spirit's dominance in recent Dota 2 competition provides substantial historical grounding for the market's positioning. The squad has consistently performed at the highest tier of international play, with multiple Major and Minor victories across 2024 and early 2025. Team Yandex, by contrast, operates at a considerably lower competitive tier within the professional circuit. Previous matchups between teams of this calibre differential typically resolve decisively in favour of the higher-ranked side, though upsets remain statistically possible in single-elimination formats where draft execution and early-game momentum can shift outcomes unpredictably.

The 100% implied probability suggests minimal divergence between sportsbook assessment and prediction-market consensus, though traditional betting operators may offer modest odds reflecting the perceived mismatch. Key variables affecting resolution include roster confirmation (both teams must field their registered lineups), technical stability of the broadcast infrastructure, and scheduling adherence. BLAST Slam's track record with fixture completion has been reliable; however, the seven-day resolution window provides contingency for unforeseen delays. Traders should monitor official BLAST communications for any last-minute roster changes or scheduling adjustments in the 48 hours preceding the match.

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

Best Prediction Markets is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

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.

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
