US monthly inflation rate (CPI) in May
Market Rules
This event predicts the United States CPI inflation rate for May 2026 measured as the one-month percent change in CPI-U (Consumer Price Index for All Urban Consumers), seasonally adjusted, from April to May 2026. The Primary Designated Source (PDS) is the U.S. Bureau of Labor Statistics (BLS) Consumer Price Index news release and associated CPI tables for May 2026, including the value reported as “1-month percent change (seasonally adjusted)” for CPI-U.
If the BLS changes its CPI presentation or table structure before publishing the May 2026 data, Futuur will select the most directly comparable CPI-U month-over-month, seasonally adjusted percent-change figure consistent with the intent of the markets. The markets will be resolved using the initially published figure at release time (not later revisions). Resolution will prioritize the substantive economic outcome and market intent over minor technicalities in formatting or presentation, and Futuur may cancel the markets with a public explanation if a fair determination becomes impossible.
