Dota 2: OG vs Tundra Esports (BO1) - BLAST Slam Group Stage

Platform comparison

Active sub-markets

Market context

OG and Tundra Esports are scheduled to meet in a best-of-one Dota 2 match at the BLAST Slam Group Stage on 27 May at 08:40 ET. The fixture forms part of the tournament's preliminary round, where both organisations compete for seeding and qualification momentum. The 100% implied probability across prediction markets suggests near-certainty that the match will be played as scheduled, though the settlement window extends to 19:10 ET the same day, allowing a seven-hour buffer for potential delays.

Historical precedent for Dota 2 group-stage fixtures at major tournaments shows cancellation or extended postponement remains uncommon, occurring in fewer than 3% of scheduled matches over the past two years. However, technical infrastructure failures, player visa complications, and unforeseen scheduling conflicts have occasionally forced rescheduling beyond the standard 24-hour window. The current 100% probability reflects confidence in tournament infrastructure rather than predictive certainty about match outcome; traders should distinguish between the likelihood of the match occurring and the likelihood of either team winning once play begins.

Traders monitoring this contract should track official BLAST communications for any roster changes, player availability updates, or venue disruptions in the 48 hours preceding the fixture. Recent tournament coverage from esports news outlets including Liquipedia and BLAST's own announcements will signal any material changes to scheduling or team composition. Internet connectivity issues affecting either team's practice environment, or unexpected roster substitutions announced within 24 hours of match time, represent the primary catalysts that could trigger settlement complications rather than straightforward resolution.

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, 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.
