Market context

The Chicago Cubs and New York Mets face off in a pivotal MLB game on 25 June at 7:10pm ET, with the Cubs holding a slight edge in season form (42–37) compared to the Mets’ struggling record (34–45). Bookmakers set the moneyline at -110 for the Cubs and -106 for the Mets, while the run line projects a combined total of 8.5 runs[1][2]. Despite the market’s current 100% YES crowd-implied probability favouring the Cubs, historical data from numberFire suggests a 57% win probability for Chicago, indicating a divergence between crowd sentiment and algorithmic modelling[1].

Traders should monitor pitcher Matthew Boyd’s recent performance (6.00 ERA) and any late-injury updates, as Boyd’s volatility could shift the outcome significantly[2]. The Mets’ attempt to break their losing slide adds psychological pressure, yet their home record (18–20) remains a concern[2]. For platform comparison, Polymarket’s implied probability model contrasts with Kalshi’s decimal odds, while Betfair’s fee structure (2–5%) differs from Smarkets’ lower 2% charge; these nuances affect how the 100% probability is interpreted across exchanges[1].

Recent coverage from ESPN highlights the Mets’ need to stabilise defensively, with key roster moves like Corey Seager’s activation potentially altering their offensive output[2]. The game’s resolution hinges on official final statistics, and any postponement will extend the settlement window until completion[3]. Investors must weigh the Cubs’ road advantage against the Mets’ home struggles, noting that the over/under odds (-114/-106) suggest a tight contest[1]. Platform-specific KYC requirements and fee tiers further influence how traders position themselves on this market.

Resolution & payout

Settlement is the biggest difference between the four platforms: Polymarket on-chain in USDC (instant), Kalshi USD via CFTC (T+1), Betfair and Smarkets in local currency via bank withdrawal (T+1 to T+3). PolyGram routes every trade directly into Polymarket's on-chain settlement, which is why payouts land fastest.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

Not under $1,500 of lifetime trading volume. Above that threshold, PolyGram triggers a quick verification flow that finishes in minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
