This market will resolve to "Yes" if there is a case of Screwworm in any livestock animal in a state of the United States other than Texas confirmed between market creation and the specified date at 11:59 PM ET. Otherwise, this market will resolve to "No". Any laboratory-confirmed screwworm infection identified within a U.S. state other than Texas will qualify, regardless of where exposure or symptom onset occurred. The primary resolution source for this market will be official government information (e.g., the CDC or USDA); however, an overwhelming consensus of credible reporting will also suffice.Recent USDA APHIS data show New World screwworm (Cochliomyia hominivorax) detections since the June 3, 2026 index case in a Zavala County, Texas calf remain concentrated in Texas livestock, with dozens of confirmations through August but only one non-Texas case—a dog in New Mexico. No livestock infestations beyond Texas have been verified, reflecting aggressive containment via sterile insect releases, 20 km quarantine zones, movement restrictions, and expanded trapping across border states. The parasite’s northward advance from Central America and Mexico since 2023, combined with summer conditions favoring fly activity, sustains spread risk, while rising sterile fly production capacity supports eradication efforts. Ongoing surveillance updates and any new multi-state livestock confirmations could shift market-implied odds on further geographic expansion.
