Elevated West Nile virus activity in New York City mosquitoes this season, with 1,568 positive pools detected through early September—nearly double last year’s pace and spanning all boroughs since mid-June—has shaped trader sentiment toward the 20–34 neuroinvasive disease cases range at 60.5% implied probability. Official NYC Health Department data show nine confirmed West Nile neuroinvasive disease cases among residents so far in 2026, following the first human case reported in mid-August, amid a national uptick that includes hundreds of cases concentrated in other states. Historical baselines indicate recent five-year averages of 25–31 annual neuroinvasive cases (range 16–36), with peak incidence typically occurring through October; the current mosquito surveillance surge and ongoing transmission window support consensus around moderate totals rather than extremes below 20 or above 49.

This market resolves based on the total number of West Nile neuroinvasive disease cases (encephalitis, meningitis, and acute flaccid paralysis) reported among New York City residents in 2026, as published by the New York City Department of Health and Mental Hygiene on its West Nile Virus Reports page at nyc.gov/site/doh/health/health-topics/west-nile-virus-reports.page.
Cases are counted as whole numbers, so each outcome covers a distinct range with no overlap or gap.
The 2026 count shown on the source as of January 1, 2027 is the starting figure.
If the DOHMH publishes or revises the 2026 count on or after January 1, 2027, this market will resolve based on the count shown on the source at 11:59 PM ET on the 14th day after the first such update, or on March 31, 2027, 11:59 PM ET, whichever comes first. If no such update occurs, this market will resolve on March 31, 2027, 11:59 PM ET, based on the 2026 count shown on the source at that time.
If no 2026 count has been published on the source by March 31, 2027, 11:59 PM ET, this market will resolve based on the sum of 2026 West Nile neuroinvasive disease case counts reported by CDC ArboNET for the five New York City counties (Bronx, Kings, New York, Queens, and Richmond). Revisions published after this market resolves will not be considered. If the DOHMH changes its reporting format or URL structure, the closest equivalent NYC Health Department publication of 2026 West Nile neuroinvasive case data will be used.Elevated West Nile virus activity in New York City mosquitoes this season, with 1,568 positive pools detected through early September—nearly double last year’s pace and spanning all boroughs since mid-June—has shaped trader sentiment toward the 20–34 neuroinvasive disease cases range at 60.5% implied probability.
