LoL: LOUD vs Leviatan Esports (BO3) - CBLOL Regular Season

Platform comparison

Market context

LOUD and Leviatan Esports are scheduled to contest a best-of-three League of Legends match within Brazil's CBLOL regular season on 16 August at 12:00 PM ET. In prediction markets, a YES share represents a bet that LOUD will win; a NO share bets on Leviatan Esports. The settlement window closes at 22:00 UTC the same day, allowing roughly ten hours after the scheduled start for the match to conclude. Should the fixture be cancelled outright, end in a draw, or remain unresolved beyond seven days, the market splits 50-50 between both outcomes.

LOUD has established itself as a dominant force in CBLOL, consistently ranking among the region's top teams across multiple seasons. Leviatan Esports, by contrast, operates as a mid-tier competitor with less consistent playoff performance. Historical matchups between these sides typically favour LOUD, though upsets remain possible in best-of-three formats where a single strong series can shift momentum. The current 100% implied probability for LOUD reflects this competitive disparity but warrants scrutiny—such extreme confidence often signals either overwhelming favouritism or limited market liquidity rather than certainty.

Traders should monitor roster announcements and injury reports in the days preceding 16 August, as CBLOL teams occasionally field substitute players on short notice. Schedule adherence matters considerably; delays beyond the seven-day threshold would trigger a 50-50 resolution regardless of eventual outcome. Technical issues during broadcast or server problems could similarly affect settlement conditions. Recent CBLOL fixtures have generally proceeded on schedule, though regional infrastructure occasionally introduces unpredictability that the current probability may not fully price in.

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 Market UK, 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

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.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

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%.
