Market context
Nongshim RedForce and KT Rolster are due to play a best-of-three in the LCK Rounds 1-2, with the market window having already closed by the time of settlement. The listed crowd price at 0% YES implies almost no on-market support for Nongshim, which is usually what you see when the order book is thin rather than when a team is truly absent from contention. In practice, esports match markets of this type often stay pinned near zero until there is clear confirmation of the line-up, start time and broadcast status, because small deposits and limited on-ramp activity can leave the book shallow and one-sided.
That is why payment flow matters here: the strongest bids tend to appear when users can move funds in quickly and cheaply. For a UK-facing crowd, Klarna and card rails can support instant top-ups, while SEPA and USDC are more relevant to larger or repeat traders who want lower friction on deposits and withdrawals. When funding is easy, depth usually improves around scheduled LCK starts and live-game cut-offs; when it is not, a market can sit distorted even if the underlying match is ordinary. The current 0% pricing therefore says as much about participation and liquidity as it does about the teams themselves.
Traders should watch for any official schedule change, delayed broadcast, or roster note from LCK channels and team social posts, since a delay beyond seven days or a non-played match would push settlement towards 50-50 under the market rules. Recent match listings on RFT.GG and Sofascore indicate the fixture was expected to go ahead on 20 May, but those pages mainly help confirm timing, not competitive state. If the game started and completed normally, the result should resolve on the winner; if not, the fallback rules become more important than pre-match pricing.
Methodology
We track LoL: Nongshim Red Force vs KT Rolster (BO3) - LCK Rounds 1-2 on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.
Resolution & payout
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
FAQ
- 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.
- What does it cost to trade on PolyGram?
- Zero. PolyGram routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.
- Do I need to KYC for this market?
- Not under $1,500 of lifetime trading volume. Above that threshold, PolyGram triggers a quick verification flow that finishes in minutes.
- How reliable are the quoted odds?
- The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
