Market context
Iron Wing and BoomBoys will contest a lower bracket first-round match at The International 2026, Dota 2's premier annual championship. The best-of-three fixture is scheduled for 20 August 2026 at 10:00 PM ET, with settlement occurring by 21 August at 08:00 UTC. Polymarket currently prices Iron Wing's victory at 47% on USDC/Polygon conditional tokens, implying near-parity between the two squads despite Iron Wing's seeding advantage from the upper bracket.
Historical precedent suggests lower bracket openers at The International favour teams with recent LAN momentum and stable five-player rosters. Iron Wing's path to this stage reflects their upper bracket performance; BoomBoys' presence in the lower bracket indicates earlier elimination, typically correlating with inconsistent regional qualifier results or mid-tournament roster adjustments. Teams entering lower bracket round one from the upper bracket have historically converted such matches at rates between 55–65%, though this varies significantly by regional strength and meta adaptation speed during the tournament's group stage.
Traders should monitor official schedule confirmations from The International organisers, as venue logistics and broadcast windows occasionally necessitate rescheduling within the 14-day postponement window (through 3 September 2026). Roster announcements or last-minute stand-in declarations would materially shift conditional token pricing. Recent patch notes released before the tournament commence will also influence hero pool accessibility for both squads, particularly if either team's signature strategies face nerfs or buffs. The settlement window's 08:00 UTC deadline on 21 August requires match completion by that timestamp; any cancellation or tie triggers 50-50 resolution regardless of underlying circumstances.

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.
