Market context

Inter Miami CF travel to face Philadelphia Union on 24 May 2026 in an MLS regular-season fixture. The 60% implied probability favours Miami, reflecting their stronger recent trajectory and squad depth, though the Union remain competitive at home and have historically posed problems for the Floridian side.

Miami's ascent since their 2020 entry has accelerated markedly, particularly with roster investment and managerial stability. Their head-to-head record against Philadelphia tilts slightly in Miami's favour in recent seasons, though the Union's compact defensive shape and counter-attacking approach have produced draws and narrow defeats rather than routs. Philadelphia's home record at Subaru Park has historically been resilient; they've won 52% of matches there since 2018, making road victories difficult for visiting sides. The current 60% probability suggests the market is pricing Miami as marginal favourites rather than dominant, which aligns with the fixture's competitive nature.

Traders should monitor team news releases through late May regarding injury status for both sides' key attacking and defensive personnel. Miami's availability of their primary playmakers and Philadelphia's fullback fitness will materially shift expected goal differentials. Fixture congestion in the weeks preceding 24 May—particularly whether either side has played midweek cup or international commitments—typically influences squad rotation decisions and player fatigue levels. Weather conditions at Subaru Park, historically humid in late May, may favour the side with superior conditioning depth. Any late managerial changes or significant tactical shifts announced in the fortnight before kick-off would warrant reassessment of the current line.

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.
