About This Event
In Sep 2026 If the, single-decimal, month-over-month percent change in the Personal Consumption Expenditures Price Index excluding food and energy is above X in September 2026 according to the Bureau of Economic Analysis, then the market resolves to Yes. The market will close at 8:25 AM ET on the expected release of the data. It will expire at the sooner of the first 10:00 AM ET following the release of the data, or one week after the expected release of the data.
What Prediction Markets Are Forecasting
Traders on Kalshi are currently putting an 87% probability on core PCE inflation staying above 0.1% month-over-month in September 2026. That's roughly a 7 in 8 chance. In plain terms, the market thinks it's very unlikely we'll see near-zero inflation that month.
But here's the interesting part: this is a low bar. A 0.1% monthly increase translates to about 1.2% annualized. That's below the Federal Reserve's 2% target. So the market isn't predicting hot inflation. It's predicting that inflation won't completely collapse to zero or turn negative.
Why the Market Sees It This Way
Three forces are shaping this forecast.
First, core PCE rarely prints below 0.1%. Since 2000, monthly core PCE readings have fallen to 0.1% or lower only about 15% of the time, mostly during recessions or their immediate aftermath. The market is essentially betting against a severe economic downturn hitting by late 2026.
Second, the Fed's own projections matter. The Federal Reserve's latest Summary of Economic Projections shows inflation hovering around 2% through 2026. That implies monthly readings averaging roughly 0.17%, comfortably above the 0.1% threshold. The market tends to align with the Fed's forecasts unless there's strong reason to doubt them.
Third, there's a structural floor under inflation. Rent inflation has been slow to cool, and services prices tend to be sticky. Even if goods prices fall, services keep the overall index positive. Getting core PCE to 0.1% or below would require synchronized weakness across most categories, which is historically unusual outside of recessions.
Key Dates and Events to Watch
The September 2026 data releases in late October 2026, but the market will react to signals long before then.
Watch the Fed's March and June 2026 meetings. If the Fed signals rate cuts due to weakening demand, that raises recession odds and pushes the probability up. Conversely, if the Fed stays hawkish, the market will see inflation as more entrenched.
Monthly CPI releases throughout 2026 will move this market. CPI and PCE track each other closely, so traders will update their expectations after every reading.
Also monitor the labor market. If unemployment starts climbing steadily in early 2026, recession probability rises, and suddenly a 0.1% or lower core PCE reading becomes more plausible.
How Reliable Are These Predictions?
Prediction markets have a solid track record on economic data releases, though not perfect. They're better at forecasting near-term events (next few months) than events a year or more out.
The 87% probability reflects both the historical rarity of sub-0.1% readings and the current economic baseline. But a lot can change in 18 months. A tariff shock, an energy crisis, or a policy mistake could shift the trajectory quickly.
One limitation: this market only asks about one specific threshold. It doesn't capture the full distribution of possible outcomes. The market might be 87% confident we stay above 0.1%, but that leaves open whether we land at 0.2% or 0.4%. For the Fed's purposes, that distinction matters a lot more than the binary outcome this market tracks.
Current Market Outlook
Kalshi traders are pricing an 87% probability that core PCE inflation in September 2026 comes in above 0.1% month-over-month. That's a high-confidence bet, though not a lock. The market is essentially saying a sub-0.1% reading, which would be a near-zero or negative inflation print, is unlikely but not impossible.
For context, core PCE has averaged roughly 0.2% to 0.3% monthly over the past decade. A 0.1% threshold is a low bar. The market's 87% pricing implies traders see roughly a 1-in-7 chance of an unusually soft inflation report nearly two years from now.
Key Factors Driving the Odds
The Federal Reserve's own projections anchor this market. The Fed's September 2025 Summary of Economic Projections shows core PCE ending 2026 around 2.2% year-over-year. Getting from current levels to that target requires monthly prints averaging roughly 0.15% to 0.2%, which keeps most months above the 0.1% threshold.
Historical base effects matter too. September 2026 compares against September 2025. If current inflation trends continue moderating, the year-over-year base gets easier, but the month-over-month calculation doesn't care about the prior year. Monthly momentum is what counts.
The labor market's gradual cooling supports continued disinflation, but not collapse. Wage growth has slowed to around 3.5% annually, which historically supports core PCE prints in the 0.2% range, not below 0.1%.
What Could Change These Odds
The biggest risk to the 87% consensus is a demand shock. A recession hitting in mid-2026 would compress margins and push monthly core PCE toward zero or negative territory. The market is implicitly pricing a soft landing as the base case.
Tariff pass-through is the upside risk. If the current tariff regime persists into 2026, import prices could keep core goods inflation elevated, pushing monthly prints toward 0.3% and making the 87% probability look conservative.
Watch the Fed's December 2025 meeting for updated projections. If the Fed revises its 2026 inflation forecast below 2%, traders will likely push this market toward 90% or higher. The market will close at 8:25 AM ET on the release date, which is typically the third or fourth week of October 2026.

Overview
The Personal Consumption Expenditures (PCE) Price Index is a primary measure of inflation used by the Federal Reserve to guide monetary policy. Unlike the Consumer Price Index (CPI), the PCE index accounts for changes in consumer behavior, such as substituting cheaper goods when prices rise, and includes a broader range of expenditures, including those made on behalf of consumers by employers and government programs. The core PCE, which excludes volatile food and energy prices, is the Fed's preferred gauge for underlying inflation trends. The Bureau of Economic Analysis (BEA) releases the PCE data monthly, typically around the end of the following month. The prediction market question focuses on the month-over-month percent change in core PCE for September 2026, which will be released in late October 2026. This specific metric is critical because the Fed has targeted a 2% annual inflation rate, and monthly changes are annualized to assess progress toward that goal. As of early 2025, inflation has cooled from its 2022 peak, but the path back to 2% has been uneven, with core PCE hovering around 2.8% to 3.0%. Market participants, economists, and policymakers will watch this September 2026 figure to gauge whether the Fed can achieve its target without triggering a recession. The outcome will influence interest rate decisions, asset prices, and consumer expectations, making it a key data point for financial markets and the broader economy.
Historical Context
The core PCE Price Index has been the Fed's preferred inflation measure since the 1990s, but it gained prominence in 2012 when the Fed formally adopted a 2% inflation target based on it. In the decade before the pandemic, core PCE consistently ran below 2%, prompting the Fed to experiment with average inflation targeting in 2020. The pandemic then triggered a surge in inflation, with core PCE peaking at 5.4% year-over-year in February 2022. The Fed responded with aggressive rate hikes, raising the federal funds rate from near zero to over 5% between 2022 and 2023. Since then, inflation has gradually declined, but the monthly changes have been volatile. For example, core PCE rose 0.3% in December 2024, an annualized rate of about 3.6%, which was above the Fed's comfort zone. In contrast, some months in 2023 saw near-zero changes. The historical pattern suggests that monthly core PCE readings can vary significantly, influenced by factors like portfolio management fees, used car prices, and housing costs. The September 2026 figure will be compared to these past trends, and market participants will look at the annualized rate to assess whether inflation is converging to 2%.
Why It Matters
The core PCE reading for September 2026 will be a key indicator for the Federal Reserve's interest rate decisions. If the monthly change is above the market's expectation, it could signal that inflation is sticky, prompting the Fed to keep rates higher for longer. Higher rates would raise borrowing costs for consumers and businesses, potentially slowing economic growth and increasing unemployment. Conversely, a low reading could open the door for rate cuts, which would lower borrowing costs and stimulate spending. Beyond the Fed, this data point affects asset prices globally, including stocks, bonds, and currencies. Investors adjust their portfolios based on inflation expectations, and a surprise in core PCE can trigger market volatility. For households, the outcome influences mortgage rates, credit card interest, and the cost of auto loans. Moreover, the political stakes are high: inflation has been a major issue in recent elections, and a high reading in September 2026 could shape the midterm campaign narratives. The prediction market on this topic allows participants to hedge against or speculate on the inflation trajectory, providing a collective forecast that can itself influence expectations.
Current Status
As of early 2025, the U.S. economy is in a delicate phase. Inflation has cooled significantly from its peak, but the last mile back to 2% has been slow. The December 2024 core PCE reading was 0.3% month-over-month, higher than the 0.2% expected, which raised concerns about persistent price pressures. The Fed has held interest rates steady since mid-2024, and market participants are divided on when rate cuts will resume. The Trump administration's policies, including potential tariffs and immigration crackdowns, could add to inflationary pressures. The September 2026 reading will be influenced by these factors, as well as by global oil prices, housing market trends, and consumer spending patterns. The prediction market for this specific month-over-month change is likely to see heightened activity as the data release approaches, with traders adjusting their positions based on incoming economic data and Fed communications.
Frequently Asked Questions
What is the core PCE price index?
The core PCE price index is a measure of inflation that excludes food and energy prices. It is produced by the Bureau of Economic Analysis and is the Federal Reserve's preferred gauge for underlying inflation trends because it is less volatile and reflects actual consumer spending patterns.
How does the Fed use core PCE in its policy decisions?
The Fed targets a 2% annual inflation rate as measured by the core PCE. The FOMC reviews monthly and quarterly PCE data to assess whether inflation is converging to that target. If core PCE is above 2%, the Fed may raise interest rates to cool demand; if it's below, it may cut rates to stimulate spending.
What is a 'good' month-over-month core PCE number?
A month-over-month change of 0.2% or lower is generally considered consistent with the Fed's 2% target when annualized. A 0.3% increase or higher is seen as too high and may prompt the Fed to maintain or tighten monetary policy.
When will the September 2026 core PCE data be released?
The Bureau of Economic Analysis typically releases PCE data for a given month in the last week of the following month. For September 2026, the release is expected in late October 2026, likely on the last business day, but the exact date is announced in advance.
Why are food and energy excluded from the core PCE?
Food and energy prices are highly volatile and can be affected by supply shocks, such as weather or geopolitical events, that do not reflect underlying demand. Excluding them provides a clearer picture of the inflation trend, which helps policymakers make more informed decisions.
