Description

These markets assess various potential inflation thresholds for the U.S. economy by examining the year-over-year change in the Consumer Price Index (CPI) for December 2026. Each threshold represents a different level of inflation that could occur, allowing participants to speculate on the likelihood of specific inflation outcomes.

Kalshi

Each market resolves to 'Yes' if the Consumer Price Index (CPI) for the twelve months ending December 2026, as reported by the Bureau of Labor Statistics to one decimal place, exceeds the specified threshold percentage. All markets share a common secondary rule: if a federal government shutdown delays the release of CPI data, the market's expiration date is extended until either the data is released or six months after the shutdown ends, whichever comes first. This ensures fair resolution even under unusual administrative circumstances.
