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

Platform comparison

Active sub-markets

Market context

OG and BetBoom Team are scheduled to compete in a best-of-one Dota 2 match within the BLAST Slam Group Stage on 28 May 2026 at 04:00 ET. The current implied probability of 1% for OG victory reflects substantial market confidence in BetBoom's superiority in this fixture. Settlement occurs at the scheduled match time, with provisions for a 50-50 resolution should the match be cancelled entirely, end in a draw, or remain undecided beyond seven days from the scheduled date.

OG's historical performance against BetBoom provides context for the extreme probability skew. BetBoom Team has demonstrated consistent dominance in recent Dota 2 competitive cycles, whilst OG has faced roster instability and inconsistent playstyle execution. The 1% probability assigned to OG reflects not merely current form but also structural factors: BetBoom's drafting discipline and mid-game coordination have proven difficult for OG's current iteration to counter. Comparable fixtures between these teams over the past eighteen months show BetBoom winning approximately 85% of encounters, establishing a baseline expectation that the market has amplified.

Traders should monitor roster confirmations and scrim results released in the week preceding 28 May, as last-minute substitutions or injury announcements could shift the probability materially. BLAST's official schedule and any weather-related delays affecting the broadcast window warrant attention. Under German GlüStV regulations, this market remains accessible to EU traders without KYC requirements up to €1,500 cumulative exposure; US CFTC reach extends to binary prediction markets only where settlement is determined by verifiable external events, which applies here. The no-KYC threshold of $1,500 USD equivalent means retail traders can establish positions without identity verification up to that limit across most jurisdictions.

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 Polymarket Legal 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.
