Pronóstico: San Jose Earthquakes vs. St. Louis City SC

Platform comparison

Market context

On Saturday, 15 August 2026, San Jose Earthquakes will host St. Louis City SC in an MLS regular-season fixture. Polymarket currently prices a San Jose victory at 3% YES, implying roughly 97% probability that the result is either a draw or St. Louis win. The conditional token pair settles at 02:30 UTC on 16 August, shortly after full-time whistle, with USDC collateral locked on Polygon throughout the settlement window.

Historical MLS head-to-head records between these clubs offer limited precedent—St. Louis City entered MLS only in 2023—but San Jose's home record and recent form provide context for reading this price. The Earthquakes have struggled with consistency in recent seasons, whilst St. Louis City has established itself as a competitive mid-table side. A 3% YES probability suggests traders view San Jose as significant underdogs despite home advantage, reflecting either poor recent form, injury concerns, or St. Louis City's relative strength in 2026.

Traders should monitor team news releases and official MLS injury reports through 15 August, particularly regarding key attacking or defensive personnel. Fixture congestion—whether either side played midweek—affects squad rotation decisions. Weather conditions at San Jose's stadium and any late tactical announcements from either manager could shift the conditional token price in the final hours before kickoff. Historical odds from traditional sportsbooks will provide real-time calibration against Polymarket's current 3% valuation.

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.
