This market resolves YES if the initial BLS Consumer Price Index release for December 2026 reports that headline CPI-U rose 0.3% or more month-over-month on a seasonally adjusted basis. Use the all-items Consumer Price Index for All Urban Consumers (CPI-U), BLS series CUSR0000SA0, and the seasonally adjusted percent change from November 2026 to December 2026 in the first BLS December 2026 CPI release. Resolve NO if that seasonally adjusted month-over-month change is 0.2% or lower. Do not use core CPI, year-over-year CPI, PCE, PPI, not-seasonally-adjusted monthly change, real earnings, or later annual revisions unless BLS corrects the initial December 2026 release before resolution. If the December 2026 CPI release is delayed, wait for the first BLS release of the December 2026 figure unless there is no BLS December 2026 CPI release by August 19, 2026, in which case resolve N/A.

Update 2026-06-18 (PST) (AI summary of creator comment): The fallback N/A date of August 19, 2026 in the market description is a stale fragment and should be ignored. Instead: if BLS never publishes a December 2026 CPI release, resolve N/A. All other resolution criteria remain unchanged.
1,000BLS has the November 2026 CPI release scheduled for Thursday, Dec. 10, 2026 at 8:30 AM ET. That makes this a real dated threshold, not a fuzzy month-in-name market.
Official sources: BLS CPI release calendar and May 2026 CPI release, which showed CPI-U at +0.5% MoM SA. So the 0.3% bar is anchored to a release that already exists on the public calendar and a recent print above threshold.
Correction to the market description: the fallback sentence saying N/A if there is no December 2026 CPI release by August 19, 2026 is a stale date fragment and should be ignored.
The resolver remains the first official BLS December 2026 CPI release: all-items CPI-U, series CUSR0000SA0, seasonally adjusted month-over-month change from November 2026 to December 2026. YES if that initial BLS figure is 0.3% or higher; NO if it is 0.2% or lower.
Current official BLS CPI schedule page lists CPI releases through November 2026, with November CPI scheduled for Dec. 10, 2026, and it does not yet list a December 2026 CPI release date. When BLS publishes the December 2026 CPI release, use that initial release. If BLS never publishes a December 2026 CPI release, resolve N/A.
