Market context
Onion Team face BRUTE in a best-of-three League of Legends match within the Hitpoint Masters Regular Season on 19 August 2026. The fixture is scheduled for 10:00 AM ET, with settlement occurring at 20:00 UTC the same day. The current crowd-implied probability of 24% for Onion Team victory reflects substantial backing of BRUTE as favourites, though the BO3 format introduces variance that single-elimination structures would not.
Historical precedent in regional League competitions shows that underdog probabilities below 25% often underweight the inherent volatility of best-of-three series. Teams classified as heavy favourites (76% implied) have failed to convert that expectation into wins at rates exceeding 15–20% across comparable Hitpoint Masters seasons, particularly when facing opponents with recent roster changes or meta-adaptation advantages. The settlement window closes at 20:00 UTC on 19 August, allowing roughly ten hours post-match for result confirmation before USDC settlement triggers on-chain.
Traders should monitor roster announcements and scrim results in the week preceding the match, as mid-season substitutions or injury disclosures can shift win probabilities substantially. Hitpoint Masters scheduling has historically experienced delays; the contract permits rescheduling until 2 September 2026 at 23:59 ET, meaning postponement risk exists if either organisation reports technical or logistical issues. Recent Hitpoint Masters broadcasts have been documented via official league channels and third-party esports databases; confirmation of fixture status should be cross-referenced against these sources before settlement.
Methodology
This page reads LoL: Onion Team vs BRUTE (BO3) - Hitpoint Masters Regular Season on-chain. Polymarket's quote comes directly from the Polygon order book — the only comparable venue with on-chain settlement. Kalshi (USD, off-chain), Betfair (GBP/EUR, off-chain) and Manifold (play-money) are listed alongside for venue context. Every CTA routes to BTC Prediction, which mirrors the Polymarket order book directly.
Resolution & payout
Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.
Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.
UK Frequently Asked Questions
- What are crypto prediction markets?
- Crypto prediction markets are on-chain smart contracts where you buy YES or NO shares on a future crypto event (e.g. "BTC above $100k by year-end"). The market price between 0¢ and 100¢ is the implied probability.
- Why USDC and not ETH or USDT?
- USDC is the Polygon standard — audited reserves (Circle, monthly attestation), deepest order book, low gas costs. ETH volatility would distort probability quotes; USDT has thinner Polygon liquidity than USDC.
- 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%.
