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

Platform comparison

Market context

Aurora and Team Yandex will face off in a best-of-three Dota 2 match during The International group stage on 14 August 2026 at 04:00 ET. The current crowd-implied probability of 41% for Aurora victory sits notably below the typical 50–50 baseline, suggesting market participants favour Team Yandex as the likely winner. This skew reflects confidence in the underdog narrative rather than overwhelming consensus; the settlement window closes immediately after the scheduled match start, leaving minimal room for rescheduling adjustments within the 14-day postponement window.

Historical precedent from prior International tournaments shows that regional representation and recent LAN performance heavily influence group-stage outcomes. Teams entering from stronger qualifying regions or with recent top-four finishes at Majors tend to command 55–65% implied probability in similar matchups. Aurora's current 41% probability suggests either a perceived experience gap, recent roster instability, or unfavourable head-to-head records against Team Yandex. Cross-platform comparison data from major sportsbooks would clarify whether this represents genuine analytical divergence or standard prediction-market volatility ahead of the event.

Traders should monitor roster confirmations and practice-stage scrim results released in the week preceding 14 August, as last-minute substitutions or injury announcements have shifted International group-stage odds by 8–12 percentage points historically. The 04:00 ET start time may also affect liquidity and line movement in Western-facing markets relative to Asian-based sportsbooks, where Team Yandex likely commands stronger backing. Any official schedule adjustments or venue changes would trigger the postponement clause, extending the settlement window to 28 August.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

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.

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.
