LoL: KT Rolster vs Dplus KIA (BO3) - LCK Round 3-4 Legend Group

Platform comparison

Market context

KT Rolster and Dplus KIA are due to meet in a best-of-three after Dplus KIA’s 2-1 win over KT in the same LCK Legend Group fixture on 9 August, a series that swung back after KT took game one. The result fits a pattern seen in their recent head-to-heads: the matchup has been relatively even over the past year, with broader history leaning slightly towards Dplus KIA overall, so a 41% implied chance on KT is consistent with a live market that is treating DK as the marginal favourite rather than a lock.[1][8][10]

For traders, the key catalysts are team-sheet confirmation, any last-minute player health or substitution news, and whether the rematch stays on the expected schedule before the settlement window closes on 12 August. Recent reporting on the finished series highlighted Dplus KIA’s comeback and bot-lane control in the deciding games, which matters because in a short series, draft quality and side selection can quickly outweigh season-long averages.[11] If either organisation makes roster changes, or if the match is rescheduled beyond seven days from the original date, that would materially change how the market should be read under the settlement rules.

UK Frequently Asked Questions

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

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%.
