If the Consumer Price Index (CPI) increases by more than 2.4% in the twelve months ending October 2025 (as represented by the one-decimal place value reported by the Bureau of Labor Statistics), then the market resolves to Yes. Outcome verified from Bureau of Labor Statistics.
In the case of a delay in data caused by a federal government shutdown impacting the reliability of the Source Agency, the market’s latest Expiration Date will be extended to the sooner of the release of the Underlying or six months after the end of the government shutdown. If no data is released for the month of October, the ‘last available’ data that will be used to calculate the Expiration Value will be the data for the last month released prior to October, which is the data for September. This is true even if November data is released prior to the Expiration Date. The calculated value will be converted to a percentage and rounded to the nearest tenth of a percent to determine the final Expiration Value in line with BLS practice.

About
The Consumer Price Index (CPI) measures monthly inflation by tracking changes in the average prices of a diverse basket of goods and services, including housing, food, transportation, and healthcare. It is a crucial indicator of rising or falling prices and offers insights into the cost of living for consumers. Fun fact: In 1926, the U.S. Bureau of Labor Statistics introduced the first official CPI to calculate inflation adjustments for federal workers' salaries.
