Philadelphia Phillies vs. San Diego Padres

Platform comparison

Active sub-markets

Market context

The Philadelphia Phillies will host the San Diego Padres on 25 May at 6:40 PM Eastern Time in a regular-season Major League Baseball fixture. The market resolves to the Phillies if they secure victory; to the Padres if San Diego wins. The 54% crowd-implied probability reflects a marginal Phillies lean, consistent with their home-field advantage and recent divisional standing within the National League East.

Historical matchup data between these franchises shows competitive balance over the past three seasons, with neither team establishing decisive dominance in head-to-head play. The Phillies' 2024 roster depth and bullpen composition have improved relative to 2023, whilst the Padres' acquisition strategy has focused on mid-rotation reinforcement. Comparable May fixtures in prior years have resolved within 2–3 run margins roughly 60% of the time, suggesting the current probability distribution reasonably captures baseline uncertainty without extreme skew toward either side.

Key catalysts include confirmed starting pitcher assignments, which typically emerge 48–72 hours before first pitch, and any late-breaking injury reports affecting position players or relief arms. Weather conditions at Citizens Bank Park—particularly wind direction and temperature—materially influence run-scoring expectations. Under German GlüStV and US CFTC frameworks, this market remains accessible to traders in most jurisdictions without KYC verification up to $1,500 notional exposure, though settlement occurs through regulated infrastructure. Traders should monitor official MLB communications for postponement notices, which would extend the settlement window beyond the scheduled 1 June deadline.

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

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.

FAQ

Is this market available outside the US?

PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

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.

What does it cost to trade on PolyGram?

Zero. PolyGram routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

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.
