Dota 2: Aurora vs GamerLegion (BO3) - The International Group Stage

Platform comparison

Market context

Aurora and GamerLegion face off in a best-of-three opening match at The International 2024 group stage, scheduled for 1:00 AM ET on 13 August. The Polymarket contract currently prices Aurora's victory at 97%, reflecting substantial confidence in the CIS-region squad. Settlement occurs at 12:10 UTC on 13 August, allowing roughly eleven hours from match start for resolution—a window that accommodates standard group-stage scheduling but leaves minimal buffer for technical delays or fixture rescheduling.

Historical precedent suggests such extreme probabilities in Dota 2 group-stage matchups typically reflect either a significant skill gap or pre-tournament roster volatility affecting one competitor. GamerLegion, a European-based organisation, has experienced roster instability heading into The International; Aurora, conversely, qualified through a more stable regional pathway. When similar probability disparities appear in esports prediction markets, they often hold through to settlement unless an unexpected withdrawal or last-minute substitution occurs—events that would trigger the 50-50 tie resolution clause rather than a competitive upset.

Traders should monitor official The International schedule announcements for any fixture delays beyond the seven-day threshold, which would force 50-50 resolution regardless of match outcome. Polymarket's conditional token mechanics on Polygon mean positions settle in USDC directly to wallets; the 97% pricing leaves minimal margin for arbitrage unless new information surfaces regarding team availability or match cancellation risk. Watch for official statements from Valve or the event organisers regarding group-stage bracket changes, which occasionally occur during the tournament's opening days.

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.

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 does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

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.
