LoL: Team Vitality vs Karmine Corp (BO3) - LEC Regular Season

Platform comparison

Market context

Polymarket is pricing Team Vitality at **31%** on this Bo3, with the contract settling through USDC on Polygon via conditional tokens once the LEC result is final. In practical terms, that means the market is effectively saying Karmine Corp remain the stronger side, but the price is still giving Vitality a meaningful upset chance rather than treating the match as a near lock.

That view is broadly consistent with comparable pre-match pricing: bookmakers in recent match coverage have also had Karmine Corp as the clearer favourite, listing them at around **1.24** decimal odds against Vitality[1]. For a Polymarket user, the key read-through is that 31% is not an isolated outlier; it sits in the same direction as conventional markets, though the on-chain price may move quickly if line-ups, patch context, or series format expectations shift closer to start time.

The main catalysts to watch are simple: whether the scheduled LEC fixture actually goes ahead on time, whether either team posts late roster or substitution news, and whether any broadcast or schedule change affects settlement timing. Because this market resolves only when a winner is officially determined — and reverts to 50-50 if the match is not played or is delayed beyond the stated window — the trade is not just about who is stronger in-game, but also about execution risk around the event itself.

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

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.
