LoL: Karmine Corp Blue vs Solary (BO1) - LFL Regular Season

Platform comparison

Market context

Polymarket’s contract is pricing **0% YES** for Karmine Corp Blue to beat Solary, which in practice means the market is assigning no live probability to KCB winning this BO1 on a USDC-settled Polygon conditional token. For a user holding exposure, the key mechanics are simple: the contract resolves to KCB only if they win the match, while cancellation, a tie, or a delay beyond the settlement rules can push it to 50-50 instead.

The historical frame is mixed rather than one-sided. Recent and archived results show Solary has had the edge in several meetings, including a 1-0 win in the Spring 2026 regular season and a 3-0 result in the Spring 2026 final, while broader head-to-head records across trackers are close enough to suggest this matchup has often been competitive rather than settled in advance[4][7][8]. That matters because BO1 League of Legends markets can move sharply on draft quality, side selection, and late roster news, even when one side appears stronger on paper.

For traders, the main catalysts are whether the fixture is played on schedule, whether either roster changes before lock, and whether the league confirms any postponement or admin issues that could affect settlement. At market close, the practical watchlist is the official LFL match state, team social posts about lineup confirmation, and any broadcast or organiser notice that would clarify whether the game started, finished, or fell into a no-contest scenario. Recent match data also shows these teams have already met in LFL play this year, giving the market a live comparable for how quickly form can swing once the draft is revealed[4][6][7].

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
