CS Herediano will face CS Cartaginés in a Liga Promerica fixture on 9 May 2026 at 22:00 ET. The market resolves on the exact final score after 90 minutes plus stoppage time, with any unmatched outcome settling to "Any Other Score." The current 0% implied probability across Polymarket's order book reflects the typical liquidity pattern for exact-score markets in lower-tier Central American football, where the combinatorial nature of possible results—with dozens of plausible scorelines—naturally fragments trading activity across numerous outcomes rather than concentrating it on a single prediction.
Exact-score markets in Liga Promerica have historically shown sparse liquidity until closer to match day, as traders await team news and lineup confirmations. Herediano and Cartaginés are established Costa Rican clubs with comparable competitive standing, making outcomes between 1–1 and 2–1 results statistically more probable than extreme scorelines. However, without current injury reports or recent form data available, the market's zero probability on any specific outcome is consistent with the early-window uncertainty typical of these fixtures.
Traders should monitor official Liga Promerica announcements regarding squad availability and any fixture rescheduling in the days preceding the match. Weather conditions in Costa Rica during May can occasionally affect playing style and goal frequency. The settlement window closes 2 May 2026 at 02:00 UTC, allowing approximately one week from now for order book depth to develop as match day approaches and team information solidifies.
This market settles from the official outcome published at https://www.unafut.com/. A proposer submits the final result to the UMA optimistic oracle on Polygon; the two-hour dispute window closes and payouts clear in USDC.
