Market context

Aurora and ex-HEROIC are scheduled to compete in a Dota 2 best-of-three match within DreamLeague's Group A stage on 15 May at 06:00 ET. DreamLeague remains one of the premier annual Dota 2 tournaments, organised by Swedish esports company ESL, attracting top-tier competitive rosters. The match outcome determines group advancement and seeding implications for subsequent tournament stages. Settlement occurs at the scheduled match time plus a seven-day grace period; cancellations, ties, or unresolved delays beyond that window trigger 50-50 resolution.

The 0% implied probability reflects either incomplete market liquidity or genuine uncertainty regarding match participation. Historical DreamLeague fixtures show cancellations remain rare, though roster changes and visa complications have occasionally affected Dota 2 tournaments. Ex-HEROIC's roster status warrants scrutiny—the organisation rebranded from HEROIC's Dota 2 division following structural changes in 2023, and squad stability has fluctuated. Aurora's recent competitive standing and any announced roster adjustments should inform baseline expectations.

Traders should monitor official DreamLeague communications and team social media for schedule confirmations, roster locks, and any withdrawal announcements prior to the settlement window. Regulatory accessibility varies by jurisdiction: German traders face GlüStV restrictions on prediction markets unless operators hold specific licensing; US CFTC oversight applies to derivatives-like contracts, though skill-based esports wagering occupies a grey area. Platforms offering no-KYC access up to $1,500 typically operate under jurisdictional arbitrage, meaning this market's accessibility depends on the operator's regulatory posture and your location.

Methodology

We track Dota 2: Aurora vs ex-HEROIC (BO3) - DreamLeague Group A on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

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.
