This market tracks whether the core Consumer Price Index (CPI), excluding food and energy, will increase by more than 0.0% in October 2026. Currently, the probability of this outcome—that CPI Core will rise more than 0.0%—is at 85.0% on Kalshi. The resolution source for this market is the Bureau of Labor Statistics’ seasonally adjusted Consumer Price Index for All Urban Consumers: All Items less Food and Energy. Traders should watch the official CPI release scheduled for November 10, 2026, as this data will determine whether the core inflation rate exceeded the 0.0% threshold and resolve the market.
The market resolves to Yes if the seasonally adjusted Consumer Price Index for All Urban Consumers: All Items less Food and Energy for October 2026 increases by the specified threshold or more. The value used is the single-decimal value reported by the BLS. If a federal government shutdown delays data release and impacts reliability, the market's expiration date extends to the sooner of the data release or six months after the shutdown ends.
Currently, prediction market participants are expressing a view on October core CPI that may differ from traditional analyst forecasts. While analysts often publish point estimates or ranges, this market allows traders to put their capital behind specific outcomes. Comparing the implied probability distribution from this market to surveys of economists reveals potential areas of agreement or disagreement regarding the direction and magnitude of the CPI release. It's important to note that prediction markets reflect a collective intelligence, potentially incorporating information not readily available to analysts.
On Kalshi, this market is priced using a continuous double auction, meaning traders are constantly posting bids and asks, establishing the current price.

Higher prices indicate a lower probability of a significant increase, while lower prices suggest a higher probability. The volume traded provides insight into the confidence level behind these price movements, and the 24-hour volume shows recent shifts in market opinion. Traders aim to profit by accurately predicting the eventual CPI core rate.
This market resolves around Nov 10, 2026, with the outcome confirmed once the official October core CPI data is verifiable from credible public reporting. The Bureau of Labor Statistics (BLS) releases this data, and the market will settle based on the reported core CPI value for October. Traders will have until the resolution time to adjust their positions based on any pre-release information or expectations. The final price will reflect the collective prediction of all participants in this market.
Several signals and events could significantly impact this market. Unexpected economic data releases, such as employment figures or other inflation indicators, could shift expectations for the October CPI. Statements from Federal Reserve officials regarding monetary policy also have the potential to move the market. Geopolitical events or supply chain disruptions could also influence inflation expectations and, consequently, the prices in this market. Any news that alters the perceived likelihood of different CPI outcomes will likely lead to increased trading volume and price fluctuations.
