Description

The core inflation rate (excluding food and energy) for urban consumers will be measured in October 2026 by the Bureau of Labor Statistics, with various thresholds tracking whether the month-over-month seasonally adjusted increase exceeds different percentage points ranging from near-zero to one percent.

Kalshi

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.

The dashboard provides a real-time view of how the market is interpreting economic indicators and forecasts.

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. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price reflects the market’s collective assessment of the probability of core CPI rising above different thresholds in October. 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.
