Live · $138,633 traded · listed on Kalshi

## About

For all outcomes in this market, Headline refers to the single-decimal month-over-month percent change in CPI-U: All Items, and Core refers to the single-decimal month-over-month percent change in CPI-U: All Items Less Food and Energy.

This is a combination market requiring ALL specified outcomes to occur for the contract to pay out. If ANY single component resolves to No or becomes impossible, the entire contract immediately resolves to No. Each component is resolved according to its corresponding Kalshi ruleset: Headline CPI MoM and Core CPI MoM each use ECONSTAT. For economic data releases, resolution uses the first officially released value (not preliminary or revised estimates unless specified). All conditions must be satisfied within the specified time period.
