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

Platform comparison

Market context

Aurora and GamerLegion are scheduled to compete in a best-of-three Dota 2 match during The International's group stage on 13 August at 1:00 AM ET. The Polymarket contract currently reflects 100% implied probability for a decisive outcome, priced entirely on the YES side, indicating the crowd expects the match to proceed as scheduled and conclude with a winner. On-chain settlement will occur via conditional USDC tokens on Polygon once the match result is confirmed, with the contract resolving to either team name or 50-50 if cancellation, delay beyond seven days, or non-completion occurs.

Historical precedent from International group stages shows fixture cancellations remain rare but material risks. The 2022 International saw minimal disruption to scheduling, though technical issues and player illness have occasionally forced rescheduling within the seven-day window. GamerLegion qualified for The International through regional qualifiers, whilst Aurora's path and seeding position will influence match dynamics. Both teams' recent LAN performances and head-to-head records provide baseline context, though International group stage matches often feature meta shifts and preparation-specific strategies that can surprise established hierarchies.

Traders should monitor official ESL or PGL announcements regarding venue conditions, player roster confirmations, and any schedule adjustments in the 48 hours preceding the fixture. Dota 2 patch notes released before the tournament lock-in date will shape team preparation and could theoretically trigger last-minute roster changes. The settlement window closes 13 August at 12:10 UTC, providing a narrow margin; any technical delays or dispute over match completion status would trigger the 50-50 resolution clause.

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.
