LoL: Karmine Corp vs Sentinels (BO3) - Esports World Cup Group B

Platform comparison

Market context

Karmine Corp and Sentinels face off today in the League of Legends Lower Bracket final at the Esports World Cup Group B, with the match set to begin at 7:20 AM ET. The crowd-implied probability sits at 100% YES for Karmine Corp, suggesting near-total confidence in a French victory despite Sentinels’ strong international pedigree. This level of certainty is unusual in high-stakes esports finals, where momentum often shifts rapidly between teams.

Historically, 100% crowd probabilities in BO3 esports matches have rarely held when the opposing side is a top-tier Western team like Sentinels. In the 2024 VCT Masters Madrid, Sentinels defeated Karmine Corp 2–0 in a Swiss-stage clash, demonstrating their ability to dominate KC in tactical matchups [2]. That result underscores the risk of treating current pricing as definitive, as past performance shows Sentinels can neutralise KC’s aggression. Traders should note that previous KC losses to SEN occurred in Valorant, not League of Legends, limiting direct comparability but still raising caution about overconfidence.

Key catalysts include the official match start time and any pre-game roster announcements, as unannounced substitutions could alter team dynamics. The Esports World Cup schedule confirms the match is live today with no delays reported, but traders must monitor for in-game technical issues or rule changes that could trigger the 50-50 settlement clause if the match begins but remains incomplete. No recent news sources have flagged roster instability, but the tight 24-hour window before settlement means any late announcement will move prices instantly.

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

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

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Prediction Today trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

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.
