Traders overwhelmingly back an 80–90 per 100,000 cumulative flu hospitalization rate for week 11 of 2026 (mid-March), with 97.4% implied probability, reflecting expectations of a severe 2025–26 influenza season akin to the 2017–18 peak when CDC data recorded 82.5 by that week amid H3N2 dominance and vaccine mismatch. Supporting evidence includes historical CDC FluView baselines—severe seasons often hit 60–90 by late winter due to rapid case surges—contrasting mild recent years (e.g., 2023–24 at ~8), but bolstered by early indicators of waning population immunity and potential antigenic drift in circulating strains. Realistic challenges include high vaccine uptake boosting effectiveness above 50%, expanded antiviral deployment like Paxlovid, or hybrid COVID-flu mitigation suppressing transmission, potentially capping rates below 70 as in 2022–23.

If the recorded data falls exactly between two brackets, this market will resolve to the higher bracket.
The resolution source for this market will be CDC FluView / FluSurv-NET (see: https://www.cdc.gov/fluview/index.html). If the FluSurv-NET hospitalization rate for the specified week is not released by 11:59 PM ET on the tenth calendar day following the date of the prior FluView weekly report release, this market will resolve to the lowest bracket.
Note: Only the CDC FluSurv-NET cumulative hospitalization rate per 100,000 population for the specified week will qualify, regardless of estimates, projections, state-level reports, or other influenza surveillance metrics published by the CDC or other sources.
