LoL: KT Rolster Challengers vs Nongshim Esports Academy (BO3) - LCK Challengers League Rounds 3-4 Challenge Group

Platform comparison

Market context

KT Rolster Challengers face Nongshim Esports Academy in a best-of-three fixture within the LCK Challengers League's Challenge Group phase, scheduled for 13 August at 01:00 ET. The 100% implied probability reflects the match's confirmed status on the official LCK Challengers schedule, with no reported cancellations or postponements as of the settlement window opening. Both organisations field academy rosters competing in South Korea's secondary competitive League of Legends circuit, where fixture reliability remains high given the structured league format and broadcast commitments.

Historical precedent across LCK Challengers seasons shows cancellations occur rarely—typically only when organisations face roster crises or league-wide scheduling disruptions. Academy fixtures have maintained near-perfect completion rates over the past two years, with delays beyond the seven-day threshold exceptionally uncommon. The current probability reflects this institutional stability rather than any specific confidence in either team's performance.

Traders should monitor the official LCK Challengers broadcast schedule and social media channels through 12 August for any roster announcements, health issues, or schedule adjustments. Recent LCK Challengers seasons have proceeded without material disruption, though unexpected player unavailability occasionally triggers brief rescheduling. The settlement window closes at 11:00 ET on 13 August, providing a narrow margin after the scheduled 01:00 ET start time for match completion and result confirmation.

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

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Prediction Today. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction.

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.
