Resolves YES if the BLS reports a year-over-year headline CPI figure below 3.0% for any single month, in any release published before January 1, 2027. Resolves NO if every release through then reports 3.0% or higher.

US headline CPI year-over-year already fell below 3.0% in 2024. For example, the July 2024 CPI release reported 2.9% year-over-year, and subsequent 2024 readings were also below 3.0%. Since the question only requires any single month reported before 2027-01-01, the condition has already been met.
There are roughly three monthly CPI releases left before 2027-01-01 (covering Aug/Sept/Oct or similar depending on release timing). Headline CPI was already near 3% in mid-2026, and monthly headline inflation is volatile due to energy and base effects. With inflation broadly disinflating from 2022 highs and only a brief dip below 3.0% needed, the chance that at least one remaining reported month prints 2.x% is high. Main risk: sticky services/shelter and renewed energy increases keeping every print at 3.0% or above.
As of my knowledge cutoff, US CPI had already fallen below 3% in some months of 2023-2024. By mid-2024, headline CPI dropped to around 2.5-2.9% range. Given the forecast date is September 2026, there are many months of data already reported. CPI readings below 3% were achieved in late 2024 (e.g., ~2.4-2.9% in mid-2024). With the question covering any release before 2027-01-01, and given CPI was already below 3% in multiple 2024 months, this very likely already resolved YES based on historical data.
Three CPI releases remain before 2027-01-01 (Sep, Oct, Nov 2026 data). Tariff-driven price level shifts from 2025 roll out of the YoY calculation in late 2026, creating favorable base effects that could pull headline inflation back toward or below 3.0%. However, sticky services/shelter inflation and the risk that tariff pass-through proves persistent keep upside risk. Monthly YoY readings carry ~0.1-0.2pp noise, so if the underlying trend sits near 3.0-3.2%, at least one of three readings dipping below 3.0% is roughly a coin flip. I estimate ~53%.
In 2025, between June and December, the CPI grew by only 0.46% TOTAL, and only because oil/gas prices tanked. From now on, CPI YoY has a stairway to heaven. With the uncertainty in Iran, I expect the prices to go crazy
Uniform baseline: always predicts 50%.
