Description
These markets collectively assess whether measles cases in the U.S. during 2026 will exceed various thresholds (500 to 12,500 confirmed cases). Resolution depends entirely on CDC's official measles case counter, which serves as the authoritative source for all platforms. The markets form a ladder structure, allowing traders to express granular views on outbreak severity.
