Market context

The real-world event is a best-of-three Counter-Strike playoff match between Infinite and ex-RUBY in CCT Europe Series #4, with the market resolving to **YES** if Infinite win and **NO** if ex-RUBY win. In prediction markets, a YES share is a claim that the stated outcome happens, while a NO share is a claim that it does not; here, the current crowd-implied probability of 0% YES means traders are pricing Infinite as a near-impossible winner or, more likely, have not yet seen reliable live information reflected in the market.[1]

For context, the market setup matters as much as team strength. GosuGamers lists the match as upcoming in the playoffs, scheduled for 19 June at 11:00 UTC, and the matchup page shows ex-RUBY ranked higher than Infinite, at 48 versus 107.[1] Dust2.us also notes that Infinite have met ex-RUBY once in the past 30 days and won that series, with Infinite taking three of their last five matches overall.[3] That kind of mixed signal is typical in esports markets: ranking favours one side, but recent head-to-head and short-run form can pull the implied price the other way.[3]

The main catalysts to watch are simple: confirmation that the map veto and broadcast timetable are holding, the first map result, and whether either roster changes before the match starts. Because this is a live tournament fixture, any postponement, technical issue, or bracket adjustment can matter for settlement, especially if the match is not played as scheduled or is delayed beyond the market’s stated window. If official match pages update line-ups or start times, that is usually the first signal traders react to, while pre-match odds from the tournament listing can reveal whether the market is moving towards ex-RUBY’s stronger ranking or Infinite’s earlier head-to-head win.[1][3]

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.
