This is a market about the one-month percent change in the seasonally adjusted Consumer Price Index for All Urban Consumers (CPI-U) published by the Bureau of Labor Statistics (BLS). This market will resolve to the one-month percent change in the seasonally adjusted Consumer Price Index for All Urban Consumers (CPI-U) in August 2026 according to the monthly BLS report. The resolution source for this market will be the BLS Consumer Price Index report released for August 2026 (https://www.bls.gov/bls/news-release/cpi.htm), currently scheduled to be released on September 11, 2026, at 8:30 AM ET. Resolution of this market will take place upon release of the aforementioned data. Note: the resolution source for this market will be the official monthly Consumer Price Index for All Urban Consumers (CPI-U) which BLS reports to one decimal point (e.g. 0.4%). Thus, this is the level of precision that will be used when resolving the market. If the BLS does not release the relevant figures on the scheduled date, this market may remain open up until the scheduled release time of the next CPI report (https://www.bls.gov/schedule). If the information is not released by that time, this market will resolve according to the figures of the most recent previous month with available data.Recent July CPI data showed headline inflation moderating to +0.1% month-over-month and core at +0.2%, with the year-over-year rate easing to 3.4%. Trader consensus now centers on a rebound for August, with 0.3% and 0.4% month-over-month outcomes holding the highest implied probabilities at 26.5% and 44.5%. This positioning reflects forecasts anticipating higher gasoline and food prices alongside firmer shelter and services components, even as core goods may ease. Persistent energy volatility from prior oil spikes and ongoing shelter pressures support the elevated odds for a 0.3–0.4% print, while the 21.5% chance on ≥0.5% captures upside risks from tariff effects and AI-related demand. The August CPI release on September 11 will test these market-implied odds against incoming data.
