Market context
Xtreme Gaming and HULIGANI will face off in Round 3 of The International's group stage on 14 August 2026, with the winner advancing through the tournament's opening phase. The match is scheduled for 4:00 AM ET and will be contested over a best-of-three series format. The 100% crowd-implied probability suggests near-certainty in the market's assessment, though the specific outcome remains unspecified pending match resolution.
The International's group stage has historically produced upsets when regional representatives face established squads, particularly in early rounds where preparation gaps and meta adaptation create volatility. HULIGANI's participation as a qualifier or regional representative typically carries lower win expectations against established organisations like Xtreme Gaming, which has maintained consistent Dota 2 competition presence. However, group-stage matches at The International have occasionally seen unexpected results when teams employ unconventional strategies or when key players underperform. The current probability weighting reflects Xtreme Gaming's perceived competitive advantage, though the margin between the teams will depend on recent scrim results and patch familiarity heading into the tournament.
Traders should monitor official tournament announcements regarding any schedule adjustments, as the settlement window extends to 28 August 2026 to accommodate potential postponements. Roster confirmations and last-minute coaching decisions typically emerge in the 48 hours before matches. Any withdrawal of either team or significant player illness would trigger the 50-50 resolution clause. Patch notes released immediately before the tournament could shift preparation advantages, particularly if either squad has specialised in heroes subsequently rebalanced.

UK Frequently Asked Questions
- Are prediction markets better than sports betting?
- Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.
- Can I bet on individual matches?
- Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.
- 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%.
