Dota 2: Iron Wing vs Team Liquid (BO3) - The International Group Stage

Platform comparison

Market context

Iron Wing and Team Liquid are scheduled to compete in a best-of-three Dota 2 match during The International Group Stage on 15 August 2026 at 01:00 ET. The contest forms part of the tournament's fourth round of group-stage play, determining positioning and momentum heading into subsequent stages. Team Liquid enters as the established favourite across most conventional sportsbooks, reflecting their consistent performance at major tournaments and deeper recent roster stability. The current prediction-market probability of 100% YES (implying Iron Wing victory) represents a stark divergence from conventional betting lines, which typically favour Team Liquid at odds between 1.50 and 1.80 across major operators. This inversion suggests either significant market inefficiency or late-breaking information not yet reflected in traditional sportsbook pricing.

Historical precedent indicates that Iron Wing has mounted competitive performances against top-tier opposition at regional qualifiers, though their record against Tier-1 teams at international events remains mixed. Team Liquid's tournament pedigree—including multiple International appearances and consistent top-eight finishes—typically translates to tighter odds compression. The 100% implied probability warrants scrutiny given the absence of recent roster announcements or injury disclosures that would justify such extreme confidence.

Traders should monitor official tournament schedules for any last-minute roster changes, stand-in declarations, or technical delays affecting either team. The settlement window closes 15 August at 12:00 ET, allowing minimal buffer for rescheduling beyond the 29 August deadline. Confirmation of final team lineups typically arrives 24–48 hours before match start.

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.
