Resolves based on CDC Cyclosporiasis surveillance page.

Resolution criteria

This market resolves to YES if the Centers for Disease Control and Prevention (CDC) Surveillance of Cyclosporiasis page reports at least one confirmed cyclosporiasis case (domestically acquired) in all 48 contiguous U.S. states (excluding Alaska and Hawaii) during the 2026 surveillance season, on or before August 31, 2026, at 11:59 PM ET.

If even one of the 48 contiguous states has zero confirmed cases on the CDC’s official surveillance map or reporting tables by this deadline, the market will resolve to NO.

Additional Resolution Details:

• Reporting Delays: Because CDC updates can lag behind actual onset dates, the market creator will wait until September 15, 2026, to allow the CDC to post surveillance data covering the period up to August 31, 2026.

• Data Sources: Resolution will be determined using the official state-by-state surveillance map or data tables provided on the CDC's dedicated page. If the CDC website becomes permanently inaccessible or ceases updating this specific surveillance map, equivalent aggregated data from state health departments published by reputable health news outlets (such as CIDRAP or the Marler Blog) will be used to verify case distribution.

Background

As of July 2026, the CDC and state health departments are tracking a significant multistate outbreak of cyclosporiasis, with hundreds of confirmed cases already documented across at least 31 states.
