This market asks whether U.S. core CPI for May 2026 will come in at -0.3% month over month or lower. That is a sharp decline for core inflation, so the result would stand out as a notable cooling in prices if the Bureau of Labor Statistics publishes it that way on June 10, 2026.
The event being measured is the BLS monthly Consumer Price Index report for May 2026, specifically the seasonally adjusted CPI for All Urban Consumers excluding food and energy, commonly called core CPI. The market resolves on the one-month percent change reported in the official BLS news release, and it uses the BLS’s one-decimal formatting, so a printed -0.3% or lower is the key threshold. If the scheduled release is delayed, the market can stay open until the next CPI release window, with fallback rules tied to the most recent month with available data.
Core CPI is watched because it strips out food and energy, two categories that can swing around from month to month, leaving a cleaner read on underlying inflation. A monthly drop of -0.3% or less would be unusual enough to raise questions about whether inflation pressures are easing quickly, while a less negative or positive reading would suggest steadier price growth. The disagreement here is about how much downward movement the official BLS report will show for May, not about a long-run inflation trend.
The biggest price mover is the actual BLS release at 8:30 AM ET on June 10, 2026, because the market resolves as soon as that figure is published. In the days before release, traders may react to any public discussion of the CPI calendar, BLS methodology, or expectations for shelter, services, and other core components, since those categories often drive the monthly number. The market’s wide spread and relatively low volume also mean even modest shifts in positioning can move the quoted price before the report arrives.

View marketThe current market price implies roughly a 17% chance for the leading outcome, based on live Polymarket pricing. That number is not a prediction from PredictionNinja and it is not a guarantee; it is the current crowd-priced view of the market and can change quickly when new information appears.
Before resolution, the main thing to verify is the exact core CPI month-over-month figure in the BLS CPI news release for May 2026, not an estimate, a headline summary, or a different inflation series. Readers should check the BLS publication date and time, because the market’s fallback rule depends on the official schedule if the report is delayed. One point of ambiguity to keep in mind is rounding: the market resolves using the one-decimal figure published by BLS, so a reading reported as -0.3% counts, while -0.2% does not.

This market is currently listed with an end date of Jun 10, 2026. Market timelines can change if the underlying event is postponed, rescheduled, or resolved early.
This is a market about the one-month percent change in the seasonally adjusted Consumer Price Index for All Urban Consumers excluding food and energy (Core 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 excluding food and energy (Core CPI-U) in May 2026 according to the monthly BLS report. The resolution source for this market will be the BLS Consumer Price Index report released for May 2026 (https://www.bls.gov/bls/news-release/cpi.htm), currently scheduled to be released on June 10, 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 one month percent change in core inflation (all items less food and energy) to only one decimal point (e.g., 0.3%). 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.
