Market context

The underlying real-world event is an MLB game between the Chicago Cubs and New York Mets at Citi Field in Flushing, New York, scheduled for 23 June 2026 at 7:10 PM ET. The Cubs, currently 40–37 and third in the NL Central, face the Mets, who are 34–59, in the opener of a four-game series. If the Cubs win, the market resolves to “Chicago Cubs”; if the Mets win, it resolves to “New York Mets”. Postponements delay resolution until the game is completed, while cancellations or ties result in a 50–50 split.

Historical precedents for similar MLB prediction markets show that 0% crowd-implied probabilities for a team often reflect extreme underperformance or injury crises, yet they can shift rapidly with lineup changes or weather. Comparable cases from the 2024 and 2025 seasons reveal that teams with sub-35 win records occasionally win single games against stronger opponents, especially in doubleheaders or makeup games, as seen in the 24 June 2026 doubleheader between these clubs[3]. This suggests the current 0% probability may be overstated if the Cubs’ recent form or pitching rotation improves.

Traders should monitor official lineup announcements, starting pitcher confirmations, and weather forecasts for Citi Field, as rain delays or cancellations could trigger resolution delays. Recent MLB coverage notes the Mets’ attempt to break a skid in this matchup, with pitching matchups and bullpen depth cited as key dependencies[4]. Regulatory frameworks also matter: German GlüStV implications may restrict access for EU users, while US CFTC reach could affect settlement compliance. The “no-KYC up to $1,500” rule enhances accessibility for small traders, allowing participation without identity verification, but does not override jurisdictional restrictions.

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.
