Dota 2: Iron Wing vs GamerLegion (BO3) - The International Elimination Round

Platform comparison

Market context

Iron Wing and GamerLegion will compete in a best-of-three elimination match at The International 2026, Dota 2's premier annual tournament. The fixture is scheduled for 16 August 2026 at 01:00 ET, with settlement closing at 11:00 ET the same day. The 75% crowd probability favours Iron Wing, reflecting their perceived competitive standing heading into the elimination bracket phase.

Historical precedent suggests that seeding disparities and recent form carry substantial weight in International elimination rounds. Teams entering the lower bracket typically face tighter margins; a 75% implied probability for the favoured side aligns with historical patterns where top-eight qualifiers maintain roughly 70–80% win rates against lower-bracket opponents in best-of-three formats. Comparable matchups from prior Internationals show that roster stability and scrim performance in the weeks preceding the event often correlate more reliably with outcomes than raw ranking alone. Traders should cross-reference both teams' group-stage records and any roster changes announced after qualifier results.

Key variables affecting settlement include fixture postponement (permitted until 30 August 2026 at 23:59 ET), technical delays, or cancellation—each triggering a 50-50 resolution. Programmatic traders should monitor official tournament schedules via ESL or PGL channels for venue updates, and set conditional alerts for roster announcements or injury disclosures within 48 hours of match time. The tight settlement window (same-day closure) requires automated position management; delayed broadcast schedules or overtime matches could compress confirmation timelines significantly.

UK Frequently Asked Questions

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
