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

Platform comparison

Active sub-markets

Market context

Aurora and OG are scheduled to compete in a best-of-one Dota 2 match during the BLAST Slam Group Stage on 29 May at 6:20 AM ET. The conditional token contract on Polymarket currently prices Aurora's victory at 100%, reflecting either overwhelming confidence in the Ukrainian organisation's form or, more likely, minimal liquidity and trading activity at this early stage of the tournament calendar. The settlement mechanics hinge on match completion: a walkover, disqualification, or forfeiture by either side triggers a 50-50 split, whilst cancellation or delays exceeding seven days from the scheduled date produce identical resolution. USDC collateral on Polygon underpins both sides of the contract, with traders holding Aurora tokens receiving full payout only if the team secures the map win.

OG's historical performance against Aurora offers limited direct precedent, though both organisations have competed across multiple Dota Pro League seasons and international events. OG's roster stability and tournament pedigree—including two International victories—typically command respect in matchup assessments, yet Aurora's recent competitive standing in Eastern European circuits and their performance trajectory through 2024 remain relevant variables. The 100% probability likely reflects sparse order-book depth rather than genuine certainty about the outcome.

Traders should monitor BLAST Slam scheduling announcements for any postponements or venue changes, particularly given the early morning ET slot which occasionally triggers logistical complications. Team roster confirmations and recent scrim results, typically shared through official Dota Pro League channels and team social media, may shift sentiment once trading activity accelerates closer to match day.

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.
