    Rules

    If the 12-month percentage change in CPI-U, U.S. city average, all items, not seasonally adjusted, in December 2027 is above 4.0%, then the market resolves to Yes.

    More rules

    The initially reported value for December 2027 will be used. This market concerns the 12-month percentage change for December 2027, not the annual-average percentage change for the specified year.
