2026 CPI Release Dates: Next Report August 12
The official U.S. inflation calendar, latest published baseline, verified core CPI market inventory, and resolution checklist.
Published July 18, 2026 · Substantially updated August 4, 2026 · Next report: August 12, 2026 · Next planned refresh: August 12, 2026
The answer first
The next U.S. Consumer Price Index report is scheduled for Wednesday, August 12, 2026 at 8:30 a.m. Eastern Time. It covers July 2026. The official remaining 2026 dates are September 11, October 14, November 10, and December 10. Two verified Polymarket event groups are currently open for July core CPI: one for the seasonally adjusted one-month change and one for the not-seasonally-adjusted 12-month change. They are separate questions, and neither is a headline-CPI forecast.
What changed in the August 4 refresh
The date was reverified
The live BLS calendar still lists July CPI for August 12 at 8:30 a.m. ET. The full-year schedule also continues to list September 11, October 14, November 10, and December 10 for the remaining 2026 releases.
The latest official baseline was added
The June release provides four distinct reference values: headline and core, each measured month over month and over 12 months. They are recorded below as context rather than carried forward as a prediction.
Two live event groups were verified
The original page made no active-market claim. This refresh verifies a seven-bucket core CPI month-over-month event and a ten-bucket core CPI year-over-year event, both active and accepting orders across every listed outcome at the check time.
The intent has evidence
At its 15-day review, this canonical had already produced 21 relevant impressions and 14 ranking queries in the latest audited 28-day Search Console window. The existing URL therefore gets a stronger date-first answer and internal links instead of a competing CPI page.
Remaining 2026 CPI release timeline
8:30 a.m. ET. This is the next scheduled release and the resolution catalyst named by the two verified July core CPI event groups.
After BLS publishes the report, this guide will record the official July values, separate the first release from any later correction, and check the market outcomes without inventing settlement evidence.
8:30 a.m. ET, four days before the first day of the September 15–16 FOMC meeting. The CPI release and the Fed decision remain different events with different official sources.
8:30 a.m. ET. This is a new reference month and a separate contract window from the September release.
8:30 a.m. ET, one week after the November 3 U.S. midterm election. Political timing does not alter the CPI series or its source.
8:30 a.m. ET. This is the final CPI publication listed on the BLS calendar for calendar year 2026.
June 2026 baseline before the July CPI report
The latest available official CPI release was published July 14 and covers June. It supplies a starting point for research, not a forecast for the next report. The four figures below use different seasonal and comparison conventions, so they should not be blended into one generic “inflation number.”
Headline CPI, month over month
−0.4%, seasonally adjusted. BLS said the all-items decline was the largest one-month decrease since April 2020, with a 5.7% fall in the energy index the largest contributor.
Headline CPI, 12 months
+3.5%, before seasonal adjustment. This is the all-items change over the 12 months ending June, not the month-over-month change.
Core CPI, month over month
0.0%, seasonally adjusted. “Core” here means all items less food and energy. This is the same series family named by the reviewed July month-over-month market.
Core CPI, 12 months
+2.6%, before seasonal adjustment. This is the same series family and comparison period named by the reviewed July year-over-year market.
Verified July core CPI prediction-market inventory
A Polymarket Gamma check on August 4, 2026 around 14:01–14:03 UTC found two active, open July core CPI event groups. All 17 component markets were active, not closed, and accepting orders. Fast-moving prices are intentionally omitted; the figures below describe event scale and rules at the timestamp.
Core CPI MoM — July 2026
Seven outcomes cover 0.0% or less, exact one-decimal buckets from 0.1% through 0.5%, and 0.6% or more. The event showed about $87,307 cumulative volume, $43,428 liquidity, and $2,213 in 24-hour volume.
Core CPI YoY — July 2026
Ten outcomes cover 2.2% or less, exact one-decimal buckets from 2.3% through 3.0%, and 3.1% or more. The event showed about $53,148 cumulative volume, $32,099 liquidity, and $2,199 in 24-hour volume.
Together, the two distinct event groups represented roughly $140,455 in cumulative volume, $75,527 in liquidity, and $4,413 in 24-hour volume at the snapshot. That combined total is descriptive only: each event has its own book, buckets, and settlement question.
How the two core CPI events differ
One-month change
The month-over-month event uses the seasonally adjusted change in core CPI-U from June to July. It asks how much the index changed over one month after the seasonal adjustment specified in the rules.
Twelve-month change
The year-over-year event uses the change in core CPI-U over the 12 months ending July before seasonal adjustment. It does not ask for the one-month figure annualized.
Same release, different cells
Both events name the August 12 BLS report, but they resolve from different values in that report. A correct answer to one contract does not determine the other.
One-decimal precision
Both reviewed rule sets say BLS reports the relevant core measure to one decimal point and that this is the precision used for resolution. More precise private estimates do not replace the published value.
CPI market resolution: eight distinctions that matter
1. CPI-U is specified
The reviewed events use the Consumer Price Index for All Urban Consumers. CPI-W, chained CPI, PCE inflation, producer prices, and private inflation estimates are different series.
2. Core is not headline
Both reviewed events specify all items less food and energy. The headline all-items number can move differently and cannot substitute for core CPI at settlement.
3. MoM and YoY use different comparisons
The one-month event compares July with June on a seasonally adjusted basis. The 12-month event compares July with July a year earlier before seasonal adjustment.
4. July is the reference month
The data month is July even though the release date is August 12. Record both fields so an August-release question is not confused with August data due in September.
5. Precision is one decimal
The rule text explicitly ties resolution to BLS one-decimal reporting. A model or newswire carrying more decimals is not the named resolution source.
6. Edge buckets are inclusive
The first and last buckets use “or less” and “or more.” Middle buckets are exact one-decimal values. Check the actual group title rather than inferring boundaries from a chart.
7. The official BLS release controls
Both events name the monthly BLS CPI news release and say resolution takes place when the data is released. Commentary, consensus surveys, and market prices are supporting context only.
8. Delay fallback is explicit
If BLS does not release the relevant figure on schedule, the rules allow the market to remain open until the next CPI release time; if the figure is still unavailable, they point to the most recent prior month with available data.
Why attention should rise before August 12
Wave 1 · Date-first search
Readers first need the exact answer: August 12 at 8:30 a.m. ET. The date now appears in the title, description, H1, answer-first introduction, timeline, schema, and FAQ.
Wave 2 · Contract comparison
As the release approaches, the two active event groups create separate questions about core CPI month over month and year over year. This guide explains the split without turning changing prices into a forecast claim.
Wave 3 · Resolution and next cycle
After publication, attention moves to the exact BLS cells, bucket resolution, and the September 11 release. The canonical can refresh for that next monthly wave instead of spawning duplicate URLs.
A repeatable CPI research workflow
Verify the release clock
Start with the live BLS schedule, record the reference month, and account for Eastern Time. Do not rely on a recycled calendar graphic.
Name the exact series
Write down CPI population, headline or core, comparison period, seasonal treatment, precision, and official source before opening an order book.
Read every outcome label
List the low edge, exact middle buckets, and high edge. Confirm inclusive wording and whether the market is one neg-risk group or separate binary books.
Timestamp market evidence
Capture bid, ask, spread, depth, volume, liquidity, and time together. Use the prediction-market odds guide before treating cents as a frictionless probability.
Map nearby catalysts separately
The 2026 jobs report calendar and September FOMC guide are useful context, but neither determines the CPI value or resolves these contracts.
Keep the watchlist educational
The biggest-movers tool can flag repricing after the release. A move is a prompt to recheck facts, rules, and liquidity—not a recommendation.
Frequently asked questions
When is the next U.S. CPI report in 2026?
The BLS is scheduled to publish July 2026 CPI data on Wednesday, August 12, 2026 at 8:30 a.m. Eastern Time.
What are the remaining 2026 CPI release dates?
The remaining scheduled dates are August 12, September 11, October 14, November 10, and December 10, all at 8:30 a.m. Eastern Time.
What was the latest CPI baseline before the August 12 report?
For June 2026, BLS reported headline CPI down 0.4% month over month and up 3.5% over 12 months. Core CPI was unchanged month over month and up 2.6% over 12 months. Those published values are context, not a forecast for July.
Are there active prediction markets for the July 2026 CPI report?
Yes. An August 4 check verified active Polymarket event groups for July core CPI month over month and July core CPI year over year. They contained seven and ten open outcome markets respectively; prices can change and are intentionally omitted here.
Do CPI prediction markets resolve on headline or core CPI?
It depends on the contract. The two July events reviewed here specify core CPI-U, meaning all items less food and energy. A headline CPI value cannot be substituted for that series.
What is the difference between core CPI month over month and year over year?
The reviewed month-over-month event uses the seasonally adjusted change from June to July. The reviewed year-over-year event uses the not-seasonally-adjusted change over the 12 months ending July. Both use one-decimal precision.
When will this 2026 CPI guide be refreshed again?
The next planned refresh is August 12, 2026 after the BLS release and market resolution. An earlier review will follow any official calendar or contract-rule change.
