San Jose Earthquakes vs. St. Louis City SC - More Markets

Platform comparison

Market context

San Jose Earthquakes will host St. Louis City SC in Major League Soccer on 15 August at 10:30 PM ET, with settlement contingent on additional markets becoming available for the fixture. The 0% implied probability reflects the current absence of such markets rather than any assessment of match outcome; this is a meta-market tracking the platform's own market-creation decisions, not the sporting event itself.

Comparable cases in prediction market infrastructure show that secondary markets—goal-scorer props, corner totals, card counts—typically materialise 48 to 72 hours before kickoff for established MLS fixtures. The San Jose versus St. Louis matchup carries standard liquidity expectations; neither club is newly promoted, and both have played multiple seasons in the league. Historical settlement patterns on kalshifees suggest that when a "more markets" contract exists, resolution hinges on whether the platform's operations team deploys the anticipated auxiliary markets by the window close, not on match circumstances. A trader evaluating this programmatically would treat it as a binary on platform behaviour rather than sport.

Catalysts are administrative rather than athletic. The settlement window closes 16 August at 02:30 UTC, approximately four hours after full-time whistle. Traders should monitor the platform's market feed and any scheduled maintenance windows during the 48-hour pre-match period. MLS fixture confirmations are typically locked 10 days in advance; no recent postponements or venue changes have been reported for this fixture. Conditional order logic could automate hedging if secondary markets do appear, allowing traders to pivot from infrastructure bets to match-specific positions.

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

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
