About This Event
In Nov 2026 If the CPI core month-over-month is exactly X in Nov 2026, then the market resolves to Yes. Early close condition: This market will close and expire early if the event occurs. This market will close and expire early if the event occurs.
Current Market Outlook
The Kalshi market for September 2026 core CPI month-over-month hitting exactly 0.4% is trading at 48%. That is essentially a coin flip. The market sees a 0.4% monthly core CPI print as the single most likely outcome, but it is far from a lock. For context, the core CPI MoM reading has hit exactly 0.4% only about 15% of the time over the past decade. The 48% price suggests traders are betting the Fed's inflation fight will stall in late 2026, not that 0.4% is a historically common number.
Key Factors Driving the Odds
The first factor is the lagged effect of monetary policy. The Fed's rate cuts, which are widely expected to begin in late 2025 or early 2026, typically feed into core inflation with a 12-18 month delay. September 2026 sits right in that window. If the Fed cuts aggressively, core CPI could drift up toward 0.4% from the current 0.2-0.3% range.
The second factor is the housing component. Shelter costs make up about 40% of core CPI, and they have been sticky. Apartment rents are still rising in Sun Belt markets, and new lease data from 2025 suggests a floor under shelter inflation. If shelter stays at 0.3-0.4% monthly, that alone pushes the headline core number higher.
The third factor is base effects. September 2026 compares against September 2025, which will likely show a low monthly reading if the economy slows. A low base makes a 0.4% print easier to achieve statistically.
What Could Change These Odds
The biggest risk to the 48% price is a recession. If the economy tips into contraction by mid-2026, core CPI could fall to 0.1% or even negative territory. That would make 0.4% an impossible target. Watch the ISM manufacturing index and initial jobless claims in Q1 2026 for early warning signs.
The other catalyst is the September 2026 FOMC meeting. If the Fed signals a pause or a rate hike on inflation concerns, the market will reprice upward. That decision comes in mid-September, right when the CPI data is released. The two events are tightly linked.
The 48% price is high for a single-point outcome. It implies the market is pricing in a narrow range of possible outcomes, with 0.4% as the modal expectation. If you think the Fed will get inflation under control, this is a sell. If you think inflation stays sticky, it is a buy. Either way, the risk-reward is tight at current levels.

Overview
The Consumer Price Index (CPI) core month-over-month metric measures the change in prices for a basket of goods and services excluding food and energy, for a single month. The 'core' designation removes volatile food and energy prices to reveal underlying inflation trends. For November 2026, this market asks whether the core CPI month-over-month change will be exactly a specific value. The Bureau of Labor Statistics (BLS) releases this data monthly, typically around the second week of the following month. The November 2026 data will be released in December 2026. This metric is a primary indicator for the Federal Reserve's monetary policy decisions, particularly interest rate adjustments. Investors, economists, and policymakers watch it closely because it signals persistent inflation pressures. The Federal Reserve targets a 2% annual inflation rate for the Personal Consumption Expenditures (PCE) price index, but the CPI core remains a key public and market benchmark. Recent years have seen high inflation, with core CPI peaking at 6.6% year-over-year in September 2022. By 2024 and 2025, inflation has moderated but remains above the Fed's target. The November 2026 reading will occur in a context of ongoing monetary policy tightening or potential easing, depending on economic conditions. Factors influencing this number include housing costs (which have a large weight in CPI), services inflation, wage growth, and global supply chains. Traders and analysts use this data to forecast Fed actions, making it a high-impact economic release. The exact value resolution means the market will pay out only if the reported number matches the specified threshold, which requires precise forecasting.
Historical Context
The CPI core month-over-month metric has been tracked since the 1950s, but its prominence grew after the 1970s inflation crisis. In the 1970s, core CPI month-over-month frequently exceeded 0.5%, contributing to double-digit annual inflation. The Volcker era from 1979-1982 saw interest rates rise to 20% to break inflation, with core CPI eventually falling to around 0.2% monthly by 1983. From the 1990s through 2019, core CPI month-over-month averaged about 0.2% per month, consistent with 2-3% annual inflation. The COVID-19 pandemic disrupted this pattern. In April 2020, core CPI fell 0.4% month-over-month due to lockdowns. Then from 2021 onward, monthly readings surged: 0.9% in April 2021, 0.6% in October 2021, and 0.5% in March 2022. The peak monthly core CPI in this cycle was 0.7% in September 2022. Since then, monthly readings have moderated but remained above pre-pandemic averages. In 2023, core CPI month-over-month averaged around 0.3%. In 2024, it averaged about 0.2-0.3%. The Federal Reserve's rate hikes from March 2022 to July 2023 raised the federal funds rate from near zero to 5.25-5.50%. By 2025, the Fed began cutting rates as inflation eased. The November 2026 reading will be compared to this history, with analysts looking for sustained monthly readings near 0.2% to signal inflation is under control. Any deviation above 0.3% would raise concerns about persistent inflation.
Why It Matters
The core CPI month-over-month number directly influences Federal Reserve interest rate decisions. A higher than expected reading can delay rate cuts or prompt further hikes, affecting borrowing costs for mortgages, car loans, and business investment. For households, this translates into higher monthly payments and reduced purchasing power. For investors, the number drives stock and bond market volatility. A 0.1% difference in monthly core CPI can shift bond yields by 10-20 basis points. The number also affects Social Security cost-of-living adjustments (COLAs), which are tied to CPI data. Millions of retirees depend on these adjustments. Additionally, the CPI data influences wage negotiations, as unions and employers reference inflation when setting pay. The November 2026 reading is particularly important because it falls late in the year, potentially shaping expectations for 2027. If inflation remains sticky, the Fed may keep rates higher for longer, increasing recession risks. Conversely, a low reading could signal that the economy is normalizing, allowing for more accommodative policy. The market's focus on an exact value reflects the precision with which traders and analysts now track inflation. It also highlights the growing use of prediction markets to forecast economic data, which can provide real-time probabilities that differ from traditional surveys.
Current Status
As of mid-2025, the core CPI month-over-month has stabilized around 0.2-0.3% for several months. The Federal Reserve has cut interest rates twice in 2025, bringing the federal funds rate to 4.00-4.25%. The labor market remains tight, with unemployment around 3.8% and wage growth moderating. Housing costs continue to be a key driver, with rent increases slowing but still positive. The November 2026 reading will depend on economic conditions over the next 18 months, including potential shocks from geopolitical events, energy prices, or fiscal policy changes. The exact value that the market is betting on has not been specified here, but typical market thresholds might be 0.2%, 0.3%, or 0.4%. Traders are closely watching services inflation and the lagged effects of monetary policy. The BLS will release the November 2026 CPI data in December 2026, likely around December 10-12.
Frequently Asked Questions
What is the difference between core CPI and headline CPI?
Core CPI excludes food and energy prices, which are volatile. Headline CPI includes all items. The Federal Reserve focuses on core measures to gauge underlying inflation trends.
How does the Bureau of Labor Statistics calculate CPI?
The BLS collects prices for a fixed basket of goods and services from thousands of retail outlets and service providers. It uses a weighted average, with weights updated periodically based on consumer spending surveys.
Why does the Federal Reserve care about the month-over-month change rather than year-over-year?
Month-over-month data provides a more timely signal of inflation trends. Year-over-year numbers can be skewed by base effects from the previous year. The Fed uses monthly readings to detect turning points quickly.
Can the November 2026 CPI data be revised after initial release?
Yes, the BLS often revises CPI data, especially for seasonal factors. Initial releases are considered preliminary. Revisions can occur up to five years later, but the market typically resolves based on the first release.
How do prediction markets for CPI data compare to economist surveys?
Prediction markets aggregate the wisdom of crowds and can update in real-time as new information emerges. Economist surveys, like those from Bloomberg, are snapshots. Studies show prediction markets often have comparable or better accuracy.
