Dota 2: TEAM VISION vs Team Resilience (BO3) - The International Group Stage

Platform comparison

Market context

TEAM VISION face Team Resilience in a best-of-three opening match at The International's group stage on 12 August, with the 87% implied probability reflecting substantial confidence in TEAM VISION's victory. The scheduling places this fixture at 10:00 PM ET, a time slot that typically favours teams with established preparation routines and stable internet infrastructure in their region.

Historical performance data from recent International tournaments shows that opening-round matches often see the higher-seeded or more established roster advance, though upsets occur in roughly 15–20% of cases when probability reaches these levels. Team Resilience would need either a significant tactical innovation or capitalisation on TEAM VISION's preparation gaps to overturn the market consensus. Previous group stages have demonstrated that teams entering as underdogs rarely exceed 20% win probability unless they've recently defeated their opponent or possess a documented counter-strategy to the favourite's core draft patterns.

Traders should monitor for last-minute roster confirmations or stand-in announcements through 11 August, as player availability issues have disrupted International matches in prior years. The settlement window closes 13 August at 08:00 UTC, allowing a full day beyond the scheduled match time for completion. Any delay extending beyond 19 August would trigger the 50-50 resolution clause, though The International's broadcast schedule typically ensures matches conclude within hours of their scheduled start. Watch for official tournament communications regarding venue or technical issues that could affect match integrity.

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

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.
