Market context
The Lower Bracket Semifinal between 3DMAX and K27 at the Stake Ranked Episode 3 Playoffs has already concluded with K27 securing a 2–0 victory, rendering the "3DMAX win" contract void for settlement. This Best-of-Three match, part of a double-elimination bracket featuring a $100,000 prize pool, saw K27 advance while 3DMAX exited the tournament [1][2]. The crowd-implied probability of 0% YES accurately reflects the completed real-world outcome, as the event is no longer pending but resolved in favour of the opponent.
Historically, prediction markets on concluded esports matches that retain open trading windows often drift to zero immediately once official results are confirmed, mirroring behaviour seen in recent Counter-Strike tournaments where late liquidity evaporates post-match [2]. Comparable cases from Stake Ranked episodes show that contracts tied to lower-bracket matches resolve definitively once the winner is declared, with no provision for reversal unless a formal disqualification occurs, which has not been announced for this fixture.
Traders should monitor official tournament announcements for any rare disqualification notices or match forfeiture reversals, though current sources confirm K27’s win as final [1]. The primary catalyst now is the settlement mechanism itself; since the match began and completed without forfeiture, the 50-50 tie clause is inactive, and the market will resolve to "K27" per the description. No further schedule dependencies exist as the playoff stage for these teams has ended [2].

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
- 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.
- How fast are USDC deposits?
- Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.
- Do I need to KYC for this market?
- On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram 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.
