Dota 2: Aurora vs ex-HEROIC (BO3) - DreamLeague Group A

Platform comparison

Active sub-markets

Market context

Aurora and ex-HEROIC are scheduled to contest a best-of-three Dota 2 match within DreamLeague's Group A stage on 15 May at 06:00 ET. The Polymarket contract currently prices both outcomes at 50-50 parity, reflecting genuine uncertainty about which roster will advance from this fixture. Settlement occurs on-chain via USDC on Polygon, with conditional tokens resolving to either team's victory or a 50-50 split if the match fails to complete within seven days of the scheduled start.

Aurora has competed inconsistently across recent Dota 2 circuits, whilst ex-HEROIC represents a reconstituted lineup following the original HEROIC organisation's departure from the scene. Historical precedent from comparable DreamLeague group-stage encounters suggests that evenly-priced matchups between rosters of similar calibre—neither clearly favoured nor demonstrably weaker—tend to reflect genuine competitive parity rather than mispricing. When both teams carry comparable recent LAN placements and scrim records, the 50-50 split aligns with empirical outcomes.

Traders should monitor DreamLeague's official schedule for any postponements or format changes, particularly given the tournament's history of rescheduling matches due to visa delays or technical issues. Roster confirmations and last-minute stand-in announcements, typically released 24–48 hours before group-stage matches, could shift the probability if either team fields a substitute player. Recent esports news outlets covering DreamLeague have noted the tournament's commitment to maintaining its schedule, though unforeseen circumstances remain a material risk factor for this settlement window's seven-day buffer.

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 PolyGram, 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.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does it cost to trade on PolyGram?

Zero. PolyGram routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
