Market context
Dplus KIA and KT Rolster meet in a best-of-three that the market has priced as close to a coin flip, with the crowd giving Dplus KIA a modest 59% edge. That sits between the teams’ recent split performance and their longer head-to-head record: KT are higher in the 2026 standings at 15-6 to Dplus KIA’s 13-8, but Dplus still lead the all-time series 17-12 and 40-34 on maps. Recent meetings have swung both ways, including KT’s 3-2 reverse sweep over Dplus in the Road to MSI playoffs and a 2-0 KT win in their July league match, which supports a narrow favourite rather than a wide one.[2][4][11][15]
The main trader watchpoint is whether either side carries forward its current form through the final pre-match announcements and any last-minute roster notes. Inven Global reported that KT arrived in strong shape after consecutive wins over T1 and Hanwha Life, while Dplus KIA had also built momentum with wins over Hanwha Life and Gen.G earlier in Round 3.[12] KT’s veteran core of PerfecT, Cuzz, Bdd and Aiming gives them more stability in a short series, whereas Dplus are leaning on a younger lineup built around Siwoo, Lucid, ShowMaker, Smash and Career.[2][13] With patch 26.11 still emphasising teamfights and objective control, confirmed starting line-ups and any substitution news matter more than broader league context.[2]

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.
- What are live sports odds on Polymarket?
- Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.
- 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%.
