LoL: Deep Cross Gaming vs GAM Esports (BO5) - LCP Group Stage

Platform comparison

Market context

Deep Cross Gaming face GAM Esports in Round 5 of the LCP Group Stage, a best-of-five match scheduled for 13 August at 05:00 ET. The crowd-implied probability sits at 100% for Deep Cross Gaming, suggesting near-certainty in the market's view of the outcome.

The 100% probability reflects either exceptional confidence in Deep Cross Gaming's superiority or a structural gap in how the market is pricing this fixture. LCP Group Stage matches involving established Vietnamese organisations typically show tighter probability distributions; GAM Esports, despite recent roster changes, maintains competitive infrastructure and a track record of producing upsets in regional play. Historical precedent from similar regional tournaments suggests that when one team receives maximum probability, execution failures, draft vulnerabilities, or unexpected player performance often create settlement risk rather than certainty. The absence of any probability mass for GAM Esports is unusual for a best-of-five format, where variance across five games typically permits lower-seeded or underdog teams meaningful paths to victory.

Traders should monitor team rosters and any last-minute substitutions announced before the 13 August fixture. Recent LCP announcements regarding player availability or coaching staff changes can materially shift match dynamics. The settlement window closes at 15:00 UTC on 13 August, leaving a compressed window between the scheduled 05:00 ET start and resolution. Delays beyond seven days without a completed result trigger a 50-50 resolution, creating tail risk if either technical issues or tournament scheduling disruptions occur. Confirmation of both squads' final lineups and any official postponement notices should be cross-referenced against the match schedule.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

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.

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%.
