Los Angeles Dodgers vs. Philadelphia Phillies

Platform comparison

Market context

The Dodgers edged the Phillies **2-1 on Tuesday night**, so the market has shifted into a near coin-flip for the series finale rather than a clear edge for either club.[2][6] ESPN’s live win probability was close to even at **43.9% Dodgers / 56.1% Phillies** while the game was in progress, which is consistent with a tight, low-scoring contest and explains why the crowd-implied **52% YES** is only a modest lean.[1]

Recent results point to a volatile matchup rather than a stable favourite. Philadelphia opened the series with a **10-7** win on Monday, before Los Angeles answered with Tuesday’s one-run victory, and CBS noted that the Dodgers had lost **seven of their last eight** games in Philadelphia before this set.[2][7] That split form is the main historical frame here: these clubs have already traded wins in the series, so the current pricing reflects short-run momentum more than a strong season-long mismatch.[2][7]

For traders, the key catalysts are the confirmed line-up, any late pitching change, and whether the game stays on schedule, because this market remains open if the game is postponed and only resolves on an official final result or 50-50 if it is cancelled or tied.[3] FOX Sports listed first pitch at **10:40 PM** local time on **NBCSP**, and the published total of **9.5** suggests the market is still reading this as a game where one swing can change the result.[3]

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
