LoL: KT Rolster vs Dplus KIA (BO1) - KeSPA Cup Group Stage

Platform comparison

Market context

KT Rolster and Dplus KIA meet in the KeSPA Cup Group Stage on 21 July at 04:15 ET, a best-of-one fixture within South Korea's premier domestic League of Legends tournament. The market currently trades at 100% YES on Polymarket's USDC/Polygon infrastructure, indicating traders are pricing near-certainty that the match will be completed with a decisive winner. This extreme pricing reflects the KeSPA Cup's status as a fully sanctioned, professionally managed event with established broadcast schedules and minimal historical cancellation risk. The settlement window closes at 14:55 UTC on match day, providing a narrow window between the scheduled start and resolution deadline.

KeSPA Cup matches have consistently reached completion across recent seasons, with forfeits and disqualifications remaining exceptionally rare at the group stage level. Both organisations maintain active rosters in the LCK and have no recent history of fixture non-compliance. The 100% probability suggests traders view match cancellation, tie outcomes, or seven-day delays as negligible scenarios given the tournament's infrastructure and both teams' operational status.

Traders should monitor official LCK and KeSPA announcements for any roster changes, health-related absences, or scheduling adjustments in the 48 hours preceding the fixture. The narrow settlement window means any technical broadcast issues or unexpected delays approaching 14:55 UTC could create resolution ambiguity. Fixture confirmation typically arrives 24–48 hours before group stage matches; absence of such confirmation would signal elevated cancellation risk and potentially warrant position reassessment.

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

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.
