How research worksThis market will resolve to "Yes" if, the U.S. Public Health Service officially withdraws or ends its recommendation for adding fluoride to U.S. drinking water, or if the recommended fluoride level is changed to 0.0 mg/L between January 20, and April 29, 2025 11:59 PM ET (see: https://www.cdc.gov/fluoridation/about/community-water-fluoridation-recommendations.html). If responsibility for directives on fluoride is transferred from the U.S. Public Health Service to another federal agency, any qualifying announcement from that new agency will qualify.
