Pronóstico: Philadelphia Union vs. Inter Miami CF - More Markets

Platform comparison

Market context

Polymarket prices this contract at 11% YES, which is a low strike for a late-season MLS meeting in Chester, Pennsylvania, with Philadelphia Union hosting Inter Miami at Subaru Park on 19 August at 7:30pm ET. On Polymarket, that view is expressed through USDC collateral on Polygon, with the market settling via conditional tokens once the listed window closes.

An 11% crowd price usually reads less like a clean forecast and more like a filter for edge cases: a long list of possible “more markets” outcomes has to clear the settlement definition, so the contract tends to trade far below the event’s headline recognition. Comparable MLS side-markets often sit in this range when the underlying fixture is visible but the specific conditional is narrow, especially when pricing depends on lineup, scoreline, or other match-day dependencies rather than the result itself. The market’s current level also suggests traders are discounting a straightforward path to settlement.

The main catalysts are final team news, any late changes to kick-off timing, and the platform’s exact market language, because those determine what the conditional tokens actually pay out. Recent coverage ahead of the match pointed to Inter Miami availability as a live factor, with Messi and Suárez reported fit while several squad players were ruled out, including Rodrigo De Paul through suspension[7]. Broadcast and fixture listings also confirmed the match at Subaru Park on 19 August at 23:30 UTC, which matters because Polymarket contracts settle against the defined time window rather than the broader night’s MLS schedule[2][5].

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.
