Prediction markets give a 14% probability to: will there be at least 10000 measles cases in the u.s. in 2026? — — Public Health – Seattle & King County is warning of potential measles exposure at multiple locations across the region after confirming new cases among residents this year.
Public health officials across multiple U.S. states are tracking significant measles outbreaks in early 2026, with Utah reporting a substantial caseload. The state has recorded 559 measles cases since an outbreak began in June 2025, with 142 of those cases reported in the last three weeks of March alone. Exposure warnings have been issued for numerous high-traffic locations, including a Trader Joe's grocery store, an LDS Church temple open house, and a Walmart, indicating widespread community transmission.

The outbreaks are not confined to Utah, with Florida and the Pacific Northwest also reporting cases. Collier County, Florida, has reported 106 cases in 2026, contributing to a statewide total of 144 for the year. Simultaneously, Oregon has confirmed 13 cases since the start of the year and is on track to surpass its 2024 peak of 31 cases, with wastewater surveillance detecting the virus in counties without yet-reported clinical cases. New exposures were also confirmed in the Seattle metropolitan area in late March. [Oregon Capital Chronicle, Apr 03]
The current multi-state spread, driven by clusters in under-vaccinated communities, presents a sustained public health challenge. Health authorities are emphasizing symptom monitoring and vaccination, as the highly contagious virus can lead to severe complications. The trajectory of these concurrent outbreaks in the first quarter will be a critical indicator for the annual national caseload, which last exceeded 10,000 in 2024. Continued surveillance and containment efforts in major exposure venues will be pivotal in the coming months. [WGCU, Apr 03]

This pattern — new wallets, single market, large conviction — has preceded correct outcomes in 73% of similar cases in our dataset.
Most YES wallets entered between 12c and 22c over the past 3 weeks. They’re sitting on 2–3x unrealized gains and none have started selling — creating a price floor around 20c. Meanwhile, NO wallets entered at 60–70c and 56% are now underwater as price drifted down to 62c.
78% of YES positions are in profit — most YES buyers entered early and are sitting on gains without selling, indicating conviction. Only 44% of NO positions are profitable — the majority bought high and are now underwater. This disparity strongly favors YES.
