One prediction market prices this story:

  • Will there be at least 5000 measles cases in the U.S. in 2026? — resolved “Yes” on 6 Nov 2026. The market resolves to "Yes" if the CDC measles case counter shows 5,000 or more confirmed cases in the United States during 2026. It resolves to "No" if the count stays below that threshold by the end of the year. Readers often mistakenly use state-level reports or news articles instead of the official CDC counter.

Odds are the market's probability that the outcome happens, updated every few minutes. They are information about what traders expect, not a forecast we make and not investment advice.
