Resolution rules

Verbatim from the venue. The analyst must quote these, never paraphrase.

If the 12-month percentage change in CPI-U, U.S. city average, all items, not seasonally adjusted, in December 2028 is above 2.5%, then the market resolves to Yes.

The initially reported value for December 2028 will be used. This market concerns the 12-month percentage change for December 2028, not the annual-average percentage change for the specified year.
