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

Platform comparison

Market context

Aurora and Team Yandex will contest a best-of-three Dota 2 match during The International's group stage on 14 August 2026, with the fixture scheduled for 04:00 ET. The market currently reflects a 28% implied probability for Aurora victory, suggesting Team Yandex are favoured at roughly 72%. This represents a substantial gap between the crowd assessment and typical sportsbook positioning for comparable tier-two regional matchups at The International, where group-stage contests between CIS and Southeast Asian representatives historically trade within a tighter 40–60 range.

Aurora's recent performance trajectory and roster stability merit scrutiny against Team Yandex's pre-tournament preparation. The CIS region has historically underperformed at The International relative to domestic expectations, with Aurora's prior group-stage appearances yielding mixed results against non-top-eight opposition. Team Yandex, conversely, qualified through a more competitive regional qualifier and enter with recent LAN experience. Analyst consensus from esports betting aggregators suggests the 28% probability slightly undervalues Aurora's chances given their demonstrated adaptability in BO3 formats, though no major roster changes or injury announcements have emerged to shift baseline expectations materially.

Traders should monitor fixture scheduling confirmations through The International's official broadcast calendar, as the 04:00 ET start time creates potential for rescheduling complications. Any pre-match coaching staff changes, stand-in player deployments, or technical delays affecting earlier group-stage matches could influence momentum and preparation time. The settlement window closes 14 August at 16:20 ET, allowing a 12-hour buffer for match completion; postponement provisions extend to 28 August, though group-stage matches rarely trigger such extensions.

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.
