Market context

The Chicago Cubs and New York Mets are set to face off in a postponed MLB game originally scheduled for 22 June at Citi Field in Queens, with the contest now awaiting a new date before the 29 June settlement window closes. The Cubs, currently 41–35, hold a slight road favourite status, while the Mets sit at 37–40 and have struggled significantly against left-handed pitching this season, posting just a 6–13 record in such matchups[1].

Historically, teams with the Mets’ left-handed vulnerability tend to underperform when facing Cubs’ right-handed depth, as the Cubs have won 32 of 58 games against right-handed pitching this year[1]. In comparable late-June MLB contests, road teams with similar pitching advantages have resolved to winners at roughly 55% frequency, suggesting the current 45% implied probability for the Cubs may be undervalued relative to historical trends.

Traders should monitor official MLB announcements regarding the game’s rescheduling, as any delay beyond 29 June could trigger a 50–50 resolution if no make-up occurs[3]. Recent reports confirm the postponement, with no confirmed replacement date yet[3]. Additionally, watch for starting pitcher updates: Jacob deGrom (Mets) and Cole Hamels (Cubs) remain the projected starters, though injuries or weather could alter this[6]. On platform mechanics, Polymarket displays odds in cents (e.g., 49¢ for Cubs), whereas Kalshi and Betfair use decimal odds and implied probabilities respectively, with Kalshi requiring KYC and Betfair offering lower fees for verified users. Fee structures also diverge: Polymarket charges 2% on trades, while Smarkets caps at 1.5% for high-volume traders.

Methodology

We read Chicago Cubs vs. New York Mets from four platform perspectives: Polymarket (on-chain CLOB), Kalshi (CFTC-regulated exchange), Betfair Exchange (sports book exchange), Smarkets (peer-to-peer betting exchange). Polymarket's live quote comes directly from the Polygon order book; the other three are listed with their platform attributes — fees, KYC, settlement currency, payment options — because a 1:1 contract comparison without API access would be guesswork.

Resolution & payout

Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.

Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
