Market context

Seattle Sounders FC will face San Jose Earthquakes on 13 May at 9:30 PM ET in a regular-season Major League Soccer fixture. Polymarket currently prices this conditional market at 0% YES, indicating either minimal trader interest in the specific outcome being tested or a settlement condition so narrowly defined that the market reflects near-zero probability of occurrence. The settlement window closes at 01:30 UTC on 14 May, giving traders roughly four hours post-match to assess whether the condition has been met. All positions settle in USDC on Polygon, with conditional tokens reflecting the binary outcome once the match concludes and official MLS records are published.

Historically, Sounders–Earthquakes fixtures have produced variable results, though Seattle holds a competitive edge in head-to-head records across recent seasons. The 0% pricing suggests traders are either absent from this particular market segment or the condition itself—likely a specific scoreline, player performance metric, or booking threshold—carries negligible historical frequency. Comparable MLS conditional markets on Polymarket have shown that niche outcome specifications often trade at near-zero levels until late-stage information arrives, then spike sharply if news makes the condition plausible.

Traders should monitor team news releases for injury updates to key players, official lineup confirmations released approximately 90 minutes before kick-off, and any weather alerts affecting Pacific time zones. MLS fixture scheduling occasionally shifts; confirmation that the match proceeds as scheduled on 13 May remains a prerequisite. Real-time match data feeds and official MLS statistics will determine settlement, so access to verified sources becomes critical once play begins.

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

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.
