Dota 2: BetBoom Team vs Team Spirit (BO1) - BLAST Slam Group Stage

Platform comparison

Active sub-markets

Market context

BetBoom Team and Team Spirit are scheduled to compete in a best-of-one Dota 2 match on 26 May as part of the BLAST Slam Group Stage. The 77% implied probability favouring BetBoom reflects their recent form and perceived roster strength, though Team Spirit remain a formidable opponent with multiple International-winning credentials. The match begins at 1:20PM ET, with settlement contingent on completion within the seven-day window; any cancellation, tie, or extended delay triggers a 50-50 resolution.

Historical context suggests caution around the current odds spread. Team Spirit have demonstrated resilience in group-stage environments despite roster transitions, whilst BetBoom's consistency has been inconsistent across LAN tournaments this season. Previous BLAST Slam iterations have seen favourites at 75%+ implied probability fail to convert at rates suggesting the market may be overweighting recent scrim results or public perception. Comparable Dota 2 matchups between tier-one teams typically settle closer to 55-60% for the favoured side when accounting for patch-dependent hero pools and mid-tournament fatigue.

Traders should monitor roster confirmations and any last-minute stand-in announcements before the 1:20PM ET start time, as both organisations have experienced unexpected player unavailability in recent months. Patch notes released in the week preceding the match could materially shift hero viability, particularly affecting Team Spirit's traditional mid-lane playmaking. Stream-based information regarding team scrimmage outcomes and coach commentary will emerge in the 48 hours prior; such signals have historically moved prediction-market odds by 3-5 percentage points in comparable esports events.

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
