About This Event
In Aug 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 August 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 excluding food and energy, commonly called core PCE, is the Federal Reserve's preferred measure of underlying inflation. Unlike the Consumer Price Index (CPI), which surveys urban consumers on out-of-pocket expenses, PCE reflects the broader spending of all households and nonprofits, and it accounts for changes in consumer behavior when prices shift. The Bureau of Economic Analysis (BEA) releases PCE data monthly, typically around the end of the following month. The month-over-month percent change in core PCE is a key indicator watched by economists, investors, and policymakers because it filters out volatile food and energy prices, providing a clearer signal of the inflation trend. The prediction market in question asks traders to forecast whether the August 2026 core PCE month-over-month change will be above a specified threshold (X), which is determined at the time the market is created. The market resolves based on the BEA's official release, which is expected in late September 2026. This type of market is part of a growing trend of using prediction markets to gauge economic expectations, offering real-time probabilities that complement traditional surveys and futures markets. Interest in this topic spikes around each monthly release, as traders and analysts adjust their positions based on incoming data, Federal Reserve speeches, and geopolitical events that could influence inflation. The outcome of this market will not only reflect market sentiment but also provide insight into how investors view the Fed's path for interest rates, as core PCE is a central input to the Fed's policy decisions. With inflation having cooled from its 2022 peak but still above the Fed's 2% target, the August 2026 reading will be a critical data point in assessing whether the disinflation process is complete or stalling.
Historical Context
The core PCE price index has been a focal point for markets since the early 2000s, but its prominence grew after the 2008 financial crisis when the Fed adopted a formal 2% inflation target in 2012. The Fed chose PCE over CPI because it is based on a broader measure of spending and better captures substitution effects. In the decade following the crisis, core PCE remained persistently below 2%, leading the Fed to adopt a flexible average inflation targeting framework in 2020. This framework allowed inflation to run above 2% for some time to make up for past shortfalls. However, the COVID-19 pandemic disrupted this dynamic, as supply chain shocks and massive fiscal stimulus drove core PCE to a peak of 5.4% year-over-year in February 2022, the highest since 1983. The Fed responded with aggressive rate hikes, raising the federal funds rate from near zero to a range of 5.25%-5.50% by July 2023. Since then, core PCE has gradually cooled, falling to 2.8% year-over-year by April 2024, but the monthly changes have been volatile, with some months showing near-zero or even negative readings. In 2025, the Fed began a rate-cutting cycle, but inflation data have been uneven, leading to uncertainty about the path of policy. The August 2026 reading will be seen in the context of this long battle to bring inflation back to target, and it will provide a test of whether the recent trend of disinflation can be sustained.
Why It Matters
The core PCE inflation rate is the Fed's primary guide for setting interest rates, which in turn affect the cost of mortgages, car loans, business investment, and government debt. If the August 2026 reading comes in above expectations, it could prompt the Fed to keep rates higher for longer, or even hike again, which would likely slow economic growth and increase unemployment. Conversely, a low reading could pave the way for rate cuts, stimulating spending and investment. Beyond the Fed, core PCE is a key input for inflation-indexed bonds, such as Treasury Inflation-Protected Securities (TIPS), and it influences the pricing of derivatives and other financial contracts. For everyday Americans, the inflation rate determines the purchasing power of their wages and savings, and it affects the annual cost-of-living adjustments for Social Security and other benefits. The outcome of this prediction market is not just a speculative exercise; it reflects the collective wisdom of traders about the future path of the economy, and it can influence business decisions and household financial planning. Moreover, the market's resolution will be based on official BEA data, making it a transparent and verifiable event, which adds to its appeal for those interested in economic forecasting.
Current Status
As of the knowledge cutoff in May 2025, the prediction market for August 2026 core PCE is in its early stages, with traders likely setting initial odds based on the current economic outlook. The latest data show core PCE at 2.8% year-over-year, with monthly changes hovering around 0.2%. The Federal Reserve has signaled that it is in a data-dependent mode, and the market will react to every monthly PCE release, as well as to other economic indicators such as employment reports and CPI data. The upcoming months will be crucial as the Fed's rate decisions will be influenced by these readings, and the prediction market will adjust accordingly. The market's threshold (X) is not specified in the topic, but it is likely to be set around the Fed's target-consistent monthly rate of 0.17% (which corresponds to 2% annualized). Traders will be watching for any signs of inflation reacceleration, which could push the monthly reading above X, or further disinflation, which would keep it below. The resolution of this market will depend on the actual BEA release, which will be the definitive source for the August 2026 month-over-month core PCE change.
Frequently Asked Questions
What is the difference between core PCE and CPI?
Core PCE is the Federal Reserve's preferred inflation measure, based on the personal consumption expenditures data from the National Income and Product Accounts. It includes a broader range of expenditures and uses a different formula that accounts for consumer substitution, while CPI is based on a survey of urban households and a fixed basket of goods. Core PCE also has a different weight for housing and tends to be lower than CPI.
