This market tracks whether the Consumer Price Index (CPI) will rise more than 0.0% in October 2026. Currently, the probability of this occurring on Kalshi is 98.0%. The resolution source for this market is based on whether the Consumer Price Index (CPI) increases by more than 0.0% (single-decimal) in October 2026. Traders should closely watch the official CPI release for October 2026, scheduled to be published by November 10, 2026, as this data will determine the market’s outcome.
Resolution is based on the single-decimal Consumer Price Index value published by the source agency for October 2026. The market closes at 8:25 AM ET on the scheduled release date of November 10, 2026. If a federal government shutdown delays the data release and impacts source agency reliability, the expiration date is extended to the sooner of the actual data release or six months after the shutdown ends.
Currently, prediction market participants are indicating a different expectation than many traditional economic analysts. While a range of forecasts exist, many analysts predict a moderate increase in the CPI for October 2026. However, this market reflects a more nuanced view, with traders assigning probabilities to a wider spectrum of potential outcomes. It’s important to remember that prediction markets represent a collective intelligence, incorporating diverse perspectives and real-time reactions to new information, which may diverge from the consensus view of professional forecasters.
On Kalshi, this market is priced using a continuous double auction mechanism, meaning traders can buy and sell contracts representing their beliefs about the future CPI. The price of a contract reflects the probability of that outcome occurring, as determined by supply and demand. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Traders adjust their bids and asks based on new information, economic indicators, and their own analysis, creating a dynamic pricing environment. The higher the demand for a particular outcome, the higher the price of its corresponding contract will rise, and vice versa.
This market resolves around Nov 10, 2026, with the outcome confirmed once the official CPI data for October 2026 is released and verifiable from credible public reporting. The resolution will be based on the percentage change in the Consumer Price Index as reported by the Bureau of Labor Statistics. Traders will then be paid out based on whether their chosen outcome aligned with the actual CPI change. The market’s outcome is not tied to any specific analyst prediction, but rather to the official government data released following the period in question.
Several key economic signals and events could significantly impact this market. Unexpected shifts in employment numbers, changes in energy prices, and geopolitical events could all influence inflation expectations and, consequently, trading activity. Any revisions to previous CPI data or statements from the Federal Reserve regarding monetary policy could also cause substantial movement. Furthermore, major supply chain disruptions or unexpected changes in consumer spending patterns could also shift the probabilities reflected in this market, leading to price fluctuations and altered trading volume.
