Market context
INTZ e-Sports face 7REX in the upper bracket quarterfinals of Brazil's Circuito Desafiante League of Legends playoffs on 18 August 2026. The best-of-three match is scheduled for 4:00 PM ET, with settlement closing roughly 14 hours after the projected finish. The 100% crowd probability reflects INTZ's standing as the stronger regional side, though this represents the market's full confidence rather than certainty—cancellations or unexpected postponements beyond the 14-day rescheduling window remain settlement risks.
INTZ have historically dominated domestic Brazilian competition, winning multiple Circuito Desafiante titles and maintaining consistent playoff appearances. 7REX, by contrast, represents a challenger-tier organisation with limited track record against top-tier opposition in this format. Head-to-head records between these sides in recent splits show INTZ winning decisively, though League meta shifts and roster changes can compress performance gaps. The crowd's unanimous positioning reflects this historical disparity rather than any recent upset signal.
Traders should monitor roster confirmations through 17 August, particularly any last-minute substitutions or injury announcements that could affect either team's preparation. Schedule adherence matters given the tight settlement window—any postponement request must be filed and approved well before the 18 August start time to remain valid under the 14-day rescheduling clause. Brazilian esports broadcasts occasionally experience technical delays; the settlement window's 02:00 UTC close on 19 August provides buffer for extended series, though a sweep would resolve hours earlier.
Methodology
This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Prediction Today, which mirrors the Polymarket order book directly.
Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
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%.
