Market context

BetBoom Team and ex-HEROIC will compete in a best-of-one Dota 2 match during the BLAST Slam Group Stage on 26 May at 05:10 UTC. The current crowd-implied probability of 51% for a BetBoom victory reflects near-parity assessment between the two rosters. The match carries standard settlement conditions: resolution occurs only if a decisive winner emerges within seven days of the scheduled start time, with cancellation or extended delays triggering a 50-50 split.

BetBoom Team has established itself as a consistent mid-tier competitor in European Dota 2, whilst ex-HEROIC represents the reformed lineup following the original HEROIC organisation's dissolution. Historical precedent suggests that matches between teams of comparable ranking typically settle near 50-50 odds in prediction markets, particularly in single-elimination formats where variance increases. The current 51% probability sits marginally above this baseline, suggesting modest confidence in BetBoom's preparation or recent form relative to their opponents.

Traders should monitor roster confirmations and any last-minute substitutions in the days preceding the match, as both organisations have experienced lineup adjustments throughout the season. BLAST Slam's scheduling has generally remained reliable, reducing forfeit risk, though technical delays during group stages have occasionally extended beyond initial windows. Recent tournament results from both teams' prior fixtures will provide the most actionable signal; any significant roster changes or coaching staff announcements would warrant reassessment of the current probability distribution.

Methodology

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to Best Prediction Markets UK, which mirrors the Polymarket order book directly.

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.
