This market will resolve to "Yes" if there have been the specified amount or more confirmed cases of Measles (Rubeola) in humans in the territory of the United States of America in 2026 according to the CDC case counter between January 1, 2026, 12:00 AM ET and December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". The resolution source for this market will be the CDC Measles (Rubeola) counter (see: https://www.cdc.gov/measles/data-research/index.html) at the resolution time. If the counter becomes unavailable, another credible source will be used. Note: Only cases reported by the CDC Measles (Rubeola) counter will qualify, regardless of reports from U.S. State agencies or other sources.**Sustained large outbreaks fueled by low MMR vaccination coverage continue to drive high 2026 U.S. measles totals.** As of September 3, CDC data show 3,134 confirmed cases—already exceeding the full-year 2025 record of 2,289—with 94% occurring in unvaccinated or unknown-status individuals and 95% linked to ongoing outbreaks across 47 jurisdictions. Major clusters persist in Pennsylvania, South Carolina, and Utah, while smaller increases appear in states such as Wisconsin and Ohio. Measles’ high basic reproduction number and airborne transmission sustain chains in under-vaccinated communities. Weekly CDC surveillance reports and state health department updates remain the key near-term data releases that could shift market-implied odds on final annual totals or elimination-status thresholds.
