Description
This event group covers an MLS match between San Jose Earthquakes and Atlanta United FC scheduled for February 28, 2026 at 7:30 PM ET. Markets span spread betting (goal-margin outcomes), both-teams-to-score, and total-goals over/under at multiple thresholds (1.5, 2.5, 3.5, 4.5).
PredictionHero - Resolution Divergence Alerts (RDA)
Unified Resolution Criteria (Consistent across platforms)
Both Polymarket and Kalshi use identical resolution windows (90 minutes plus stoppage time, no extra time), identical official source (mlssoccer.com for Polymarket; MLS official records for Kalshi), and identical postponement/cancellation handling (remain open until completion; 50-50 split if canceled entirely).
Primary resolution logic:
Official MLS Soccer (mlssoccer.com) final score after 90 minutes plus stoppage timeCore resolution logic:
- Spread markets (SJ -1.5, SJ -2.5, ATL -1.5, ATL -2.5) resolve based on final goal differential; the favored team must win by the specified margin or greater to win the market
- Both-Teams-to-Score resolves Yes if each team scores at least one goal; No if either team finishes with zero goals
- Over/Under markets (1.5, 2.5, 3.5, 4.5) resolve Over if combined goals meet or exceed the threshold plus one (e.g., Over 1.5 = 2+ goals); Under if below
- Resolution scope is strictly 90 minutes of regular play plus stoppage time; extra time and penalties are excluded
- Official source is mlssoccer.com final score; if game is started but not completed, resolution follows the official final score published on that platform
Edge cases & Clarifications:
- Game Postponed: Markets remain open until the game is completed; no early resolution occurs
- Game Canceled (No Make-Up): All markets in the group resolve 50-50 (split pool equally between Yes and No outcomes)
- Game Started But Not Completed: Resolution follows the official final score published on mlssoccer.com at the time of official completion
- Extra Time or Penalties: These are explicitly excluded from all market resolutions; only 90 minutes plus stoppage time counts
Timing:
Resolution occurs after the match concludes on February 28, 2026 (or the rescheduled date if postponed), based on the official final score published on mlssoccer.comOur PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.
