Description

This event group focuses on predicting the annual inflation rate as measured by the Consumer Price Index (CPI) for the twelve months ending August 2026, according to the Bureau of Labor Statistics.

PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

All markets consistently use the official BLS CPI report for August 2026 as the resolution source, with inflation measured to one decimal place.Primary resolution logic: Bureau of Labor Statistics (BLS) Consumer Price Index report released for August 2026

Core resolution logic:

  • The market resolves based on the percentage change in the CPI over the 12-month period ending August 2026.
  • Inflation is reported to one decimal place by the BLS, and this precision will be used for resolution.
  • Markets with thresholds (e.g., >3.0%, >3.1%, etc.) will resolve to Yes if the reported value meets or exceeds the threshold, and No otherwise.
  • The Polymarket market for 4.0% or more resolves to Yes if the reported value is 4.0% or higher.

Edge cases & clarifications:

  • BLS Report Delay: If the BLS does not release the August 2026 CPI report on the scheduled date, the market will resolve based on the most recent previous month with available data.
  • Exact Threshold Values: For thresholds like 3.0%, the market resolves to Yes if the reported value is 3.0% or higher. For example, a report of exactly 3.0% triggers a Yes outcome for the >3.0% market and a No outcome for the 2.9% or less market.
Timing: Resolution occurs upon the release of the BLS Consumer Price Index report for August 2026, currently scheduled for September 11, 2026, at 8:30 AM ET.Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms. They do not replace or supersede the official rules and description of any prediction market. Users are solely responsible for reviewing and understanding the applicable rules and resolution criteria before placing any trade or bet. If you notice a potential inconsistency, discrepancy, or error in an alert, please report it to our team so we can review and improve the accuracy of our data.

Polymarket

This is a market about inflation over the 12-month period ending August 2026, before seasonal adjustment, as reported by the Bureau of Labor Statistics. This market will resolve to the percentage change in the Consumer Price Index (CPI) over the 12-month period ending in August 2026 according to the monthly Bureau of Labor Statistics (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 BLS CPI news release, which reports inflation over 12-month periods to only one decimal point (e.g., 2.9%). 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.

Kalshi

Resolution is determined by the Consumer Price Index year-over-year percentage increase for the twelve months ending August 2026, as reported by the Bureau of Labor Statistics and represented to one decimal place. Each market resolves to Yes if the CPI increase exceeds its specified threshold. The thresholds range incrementally from above 3.0% to above 5.0%. In the event of a federal government shutdown that delays data release or impacts the reliability of the Bureau of Labor Statistics, the market's expiration date will be extended to the sooner of either the actual release of the CPI data or six months following the end of the government shutdown.
