New York Mets vs. Philadelphia Phillies

Platform comparison

Market context

The Mets travel to Citizens Bank Park on 19 July for a regular-season matchup against the Phillies, with first pitch at 1:35 PM ET. Polymarket currently prices a Mets victory at 69% (reflected in USDC-denominated conditional tokens on Polygon), implying roughly 31% probability for a Philadelphia win. The settlement window extends to 26 July, allowing for postponements or rescheduling within that seven-day buffer.

Historical context suggests this probability reflects Philadelphia's marginal home-field advantage offset by New York's recent form. The Phillies have won the National League East in consecutive seasons and maintain a stronger run differential than most division rivals, yet the Mets have shown competitive resilience in head-to-head matchups. Mid-July games carry less predictive weight than September contests, as roster composition and injury status remain fluid; the current 69% lean towards New York likely incorporates recent win-loss records rather than structural team quality alone.

Traders should monitor starting pitcher assignments, which typically become official 24–48 hours before game time. Any late roster moves—particularly injury announcements affecting position players or bullpen depth—can shift conditional token valuations meaningfully. Weather conditions at Citizens Bank Park, including heat and humidity forecasts for that afternoon slot, historically favour teams with deeper benches. The Phillies' recent injury history and the Mets' bullpen availability heading into late July will constitute the primary information catalysts before settlement.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

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.

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?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Polymarket Scam? trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

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.
