There is a significant trap in the rules: if the CDC fails to publish the report within the strict timeframe, the market defaults to the lowest bracket (<70) regardless of the actual hospitalization rate. The tie-breaker rule that rounds up boundary values also requires careful attention.

Predicting the cumulative flu hospitalization rate for a specific week is a niche topic. While public health data is standard, the general public rarely considers specific bracket predictions like this; it appeals mainly to hardcore data traders on specific prediction platforms.

April 10, 2026 - April 12, 2026, the price of the 80–85 bracket surged from 47.5c to 81.5c, while the 85-90 option plummeted from 48c to 12.5c, and lower brackets like <70 and 70-75 crashed from over 40c to under 2c. This was driven by the release of the latest CDC flu hospitalization surveillance data, which solidified expectations for the 80-85 range. April 10, 2026 - April 11, 2026, the price of the 80–85 bracket surged from 47.5c to a peak of 85.5c. This was driven by capital rapidly concentrating on this outcome as the CDC's flu hospitalization data became clearer. April 10, 2026 - April 10, 2026, the prices of lower-end brackets such as <70, 70-75, and 75-80 plummeted from over 40c to under 5c. This was primarily due to liquidity adjustments following market initialization and the confirmation that the final data would land in a higher bracket.
