Rules

How this market was settled

This market will resolve to "Yes" if there have been the specified amount or more confirmed domestically acquired cases of cyclosporiasis in humans in the territory of the United States of America since May 1, 2026, according to the CDC surveillance count by July 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". The resolution source for this market will be the CDC Surveillance of Cyclosporiasis page’s “U.S. cases reported to CDC” count (see: https://www.cdc.gov/cyclosporiasis/php/surveillance/index.html) at the resolution time. If the counter becomes unavailable, another credible source will be used. Note: Only cases reported by the CDC as confirmed domestically acquired cases of cyclosporiasis will qualify, regardless of reports from U.S. State agencies or other sources. Travel-associated cases acquired outside the United States will not qualify.
