Platform comparison

Active sub-markets

Market context

BetBoom Team, a Russian-based Dota 2 organisation, faces ex-HEROIC in a best-of-one group stage match at the BLAST Slam tournament on 26 May at 05:10 UTC. The fixture is a single-elimination encounter where either side advances or is eliminated from the tournament bracket. Settlement occurs immediately upon match conclusion, with a seven-day grace period for delays before the market defaults to 50-50 resolution.

The 51% crowd probability favouring BetBoom reflects modest confidence rather than consensus. Comparable Dota 2 group-stage matches between similarly ranked teams historically settle within a 48–54% range when rosters remain stable and recent form is mixed. BetBoom's recent tournament placements and ex-HEROIC's roster composition—particularly any recent transfers or stand-in arrangements—will anchor the true probability. Teams with established scrim records and bootcamp preparation typically outperform those entering cold, a dynamic that shifts odds by 3–7 percentage points in historical data.

Traders should monitor roster announcements through 25 May, as last-minute substitutions or illness can trigger odds swings. BLAST's official schedule updates and team social media channels will signal any format changes or delays. Liquidity depth depends on deposit flows; traders using Klarna installment rails or SEPA transfers may experience settlement delays if withdrawal requests spike post-match, particularly if the result contradicts crowd expectations. Watch for tournament bracket confirmations and any public statements from either organisation regarding preparation status in the 48 hours before kickoff.

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.
