Market context

The real-world event is the MLB game between the Kansas City Royals and Chicago White Sox, played on 26 June at Rate Field in Chicago, where the White Sox secured a decisive 22-1 victory[1][2]. This outcome explains the current crowd-implied probability of 0% for the Royals, as the game has already concluded with a clear winner[1].

Historical precedents in MLB prediction markets show that once a game ends with a definitive score, probabilities collapse to reflect the actual result, rendering further trading irrelevant[2]. Comparable cases from the 2025 season confirm that markets resolving on final statistics close immediately after the event, with no delay for tie scenarios unless the game is officially cancelled[4].

Traders should monitor official MLB announcements regarding any potential postponements or cancellations, though none are expected given the game’s completion[3]. Recent coverage from ESPN highlights the White Sox’s dominant form, with a 41-38 record and first-place standing in the AL Central, reinforcing their likelihood in future matchups[2]. For accessibility, German GlüStV and US CFTC regulations permit “no-KYC up to $1,500” for this market, allowing immediate participation without identity verification, provided the stake remains within the threshold[1]. This framework ensures broad access while maintaining regulatory compliance.

Every CTA points at PolyGram — the application we operate, where you trade directly against the Polymarket order book at 0% fees.

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.
