Rules
The Bureau of Labor Statistics determines the outcome using the Consumer Price Index Database for All Urban Consumers (Current Series), specifically the Boston, all-items, Not Seasonally Adjusted CPI series. The outcome is Yes if the published value is above the value specified in the market question and No otherwise; resolution occurs when the BLS releases the CPI data at 7:30 AM CT on December 10, 2026, subject to any delay, schedule change, or review under the contract terms, and this contract is not subject to early resolution.
About
The Consumer Price Index (CPI) tracks what consumers pay for a fixed basket of goods and services. The relevant CPI measure is the unadjusted, all-items CPI for Boston published by the U.S. Bureau of Labor Statistics.
