Market context
Vitality’s meeting with Spirit is a best-of-three quarter-final in the Esports World Cup Counter-Strike playoffs, with the settlement clock closing a few hours after the scheduled start. The market’s 56% implied YES price suggests a modest lean to Vitality, but not a strong one, which fits a knockout match where one map swing can flip the series.
The bracket shape matters here: both sides came through the playoff field after mixed group-stage routes, and Spirit were still one of the more efficient teams once the bracket started, while Vitality had already shown some vulnerability in earlier rounds. Reports before the playoffs placed both teams on the same half as other top contenders, so a semi-final path was never the issue; the question is whether Vitality’s current edge is enough to beat a team of similar tier in a short series, rather than over a larger sample.
Programmatically, the main triggers are simple: confirm the match actually starts on time, then watch for any schedule slip, server delay or official bracket reshuffle before the settlement window ends. The event’s CS2 playoffs run from 19 to 23 August, with all playoff matches excluding the final played as BO3, so any postponement would only matter if it moved outside the market’s rescheduling cutoff. For a rules-based workflow, the practical inputs are the published bracket, live start status and whether the fixture is completed as Vitality or Spirit rather than defaulting to a no-play 50-50 outcome.
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
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.
