LoL: Gen.G vs KT Rolster (BO5) - LCK Road to MSI

Platform comparison

Active sub-markets

Market context

Gen.G and KT Rolster will compete in a best-of-five lower bracket semifinal match within the League of Legends Champions Korea (LCK) qualifying tournament for the Mid-Season Invitational. The winner advances to the lower bracket final; the loser is eliminated from MSI qualification. A YES share represents a bet on Gen.G's victory, whilst a NO share represents a bet on KT Rolster. The current 79% implied probability for Gen.G reflects market confidence in their advancement, leaving roughly 21% probability assigned to KT Rolster.

Gen.G's recent domestic form and roster stability have historically positioned them as favourites in high-stakes LCK matchups. KT Rolster, however, has demonstrated resilience in lower bracket runs during previous seasons, occasionally upsetting higher-seeded opponents through disciplined macro play and mid-game coordination. The 79% probability suggests the market views Gen.G as substantially stronger, though not prohibitively so—a gap consistent with seeding disparities rather than a near-certain outcome.

Traders should monitor team announcements regarding player availability or substitutions before the 13 June settlement window closes. Patch notes released in the week preceding the match may favour one team's champion pool or playstyle. The match's scheduled 4:00 AM ET start time means European and Asian traders will have different real-time access to live updates. Any postponement beyond seven days without a completed result triggers a 50-50 resolution, introducing scheduling risk that could shift probability if delays appear likely.

Methodology

We track LoL: Gen.G vs KT Rolster (BO5) - LCK Road to MSI 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.
