Market context

The Stake Ranked Episode 2 Playoffs features a best-of-three upper bracket quarterfinal between Argentine outfit 9z and Sharks on 27 May at 1:30PM ET. 9z enter as the favoured side at 67% implied probability, reflecting their stronger recent form in regional competition and established roster stability. Sharks, whilst competitive in South American Counter-Strike, have shown inconsistency across LAN events this season. The match determines seeding for the semi-finals; a 9z victory maintains their trajectory toward the tournament's latter stages, whilst a Sharks upset would force 9z into the lower bracket.

Historical precedent from prior Stake Ranked tournaments suggests that seeding-based probability gaps of this magnitude—roughly two-to-one odds—tend to hold when rosters remain unchanged and recent form aligns with pre-tournament expectations. However, best-of-three formats introduce volatility; map pool matchups and individual player performance on the day can compress perceived advantages. Argentine regional fixtures have occasionally produced upsets when Sharks field their full roster without roster changes or illness affecting key players.

Traders should monitor roster confirmations through 26 May, as last-minute substitutions have historically shifted book depth on South American matches. Settlement occurs at 23:30 UTC on 27 May; matches delayed beyond 2 June without completion trigger the 50-50 resolution clause. Deposit friction via Klarna or SEPA transfers may affect liquidity if European traders face payment delays, potentially widening spreads in the final hours before kick-off.

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

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.
