Health-Statistic Revision Lag Trade

Public health statistics are provisional when first released and get revised for months as death certificates, lab confirmations and late reports come in — nearly always upward. A market resolving on the final figure while pricing off the provisional one is systematically mispriced in a known direction. You model the historical revision profile for each series and take the side the revision pattern favors.

What you need to run it

Vintage history of provisional versus final figures for each statistical series
Revision-magnitude model by reporting lag and jurisdiction
Confirmation of whether each market resolves on the provisional or final release

Where this applies

Markets on Polymarket where health-statistic revision lag trade is the natural play:

Will annual overdose deaths exceed 100,000 in the final CDC figure?
Will excess mortality for the year be revised above the initial estimate?
Will the final case count for the outbreak exceed 10,000?
