Market context
The International 2026 Group Stage will feature a best-of-three encounter between BoomBoys and Iron Wing on 13 August at 05:00 ET. Both squads qualified through regional qualifiers and will compete in a round-robin format where seeding and momentum carry material weight for knockout advancement. The 56% implied probability for BoomBoys reflects their standing as the marginal favourite, though the market has priced in meaningful uncertainty given the compressed preparation window between qualifier resolution and group play.
Head-to-head records between these rosters remain sparse at the highest tier, making recent LAN performances and online league results the primary reference points. BoomBoys' trajectory through their regional qualifier and any roster changes—particularly mid-lane or support adjustments—will determine their ability to execute against Iron Wing's likely draft tendencies. Iron Wing's qualification path and whether they've fielded the same five-player line-up throughout their preparation phase are critical unknowns; any last-minute substitutions due to visa delays or illness would shift the matchup calculus substantially.
Traders should monitor official The International schedule confirmations through the event's ticketing and broadcast partners, as 05:00 ET start times occasionally shift when regional broadcast windows conflict. Patch notes released between now and 13 August will reshape hero viability; any hero nerfs or buffs affecting either team's signature champions could swing the series. Team announcements regarding stand-in players or coaching staff changes in the final week before group play should be treated as material information, as The International historically sees last-minute roster adjustments that affect preparation depth.

- Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.
- What are live sports odds on Polymarket?
- Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.
- How fast do sports winnings settle?

- What's the difference between match odds and outright odds?
