The Chicago Fed National Activity Index measures overall economic activity across various sectors in the United States. Each month, the index provides insight into the nation's economic health by aggregating data from different indicators. This set of markets focuses on predicting whether the index value for August 2026 will exceed specific thresholds, reflecting expectations about economic expansion or contraction.
All markets resolve based on the Chicago Fed National Activity Index (CFNAI) headline value for August 2026, as published in the first official release by the Federal Reserve Bank of Chicago. The CFNAI used for settlement is the monthly index, not the three-month moving average or the Diffusion Index. Once the initial August 2026 value is released, any subsequent revisions to the index will not impact market resolution. Each market has a distinct threshold: if the reported CFNAI value exceeds the specified level (-0.40, -0.30, -0.20, -0.10, 0.00, 0.10, or 0.20), the corresponding market resolves to Yes; otherwise, it resolves to No. The thresholds progressively indicate stronger economic performance, allowing participants to assess varying degrees of economic activity.
Currently, prediction market odds reflect a different perspective than many traditional analyst forecasts for the Chicago Fed Index. While many analysts predict a modest increase, this market shows a more cautious outlook, with traders pricing in a higher probability of a flat or negative reading. It’s important to remember that analysts rely on economic models and historical data, while this market represents the collective judgment of individuals willing to put their capital at risk. This difference in perspective can be valuable for a more comprehensive understanding of potential outcomes.
On Kalshi, this market is priced using a continuous double auction, meaning traders can buy and sell contracts at any time, setting the price based on supply and demand. The price represents the probability of the Chicago Fed Index being above or below a certain threshold. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The higher the price, the greater the perceived likelihood of a positive index reading. Traders are constantly adjusting their bids and asks based on new information and their own analysis, creating a dynamic and efficient price discovery process for this market.
This market resolves around Sep 28, 2026, with the outcome confirmed once the official Chicago Fed National Activity Index for August is released and verifiable from credible public reporting. The resolution will be based on the actual value of the index as published by the Federal Reserve Bank of Chicago. Traders will then be paid out based on whether their contracts align with the final index value. The market will close prior to the official release to prevent manipulation and ensure a fair outcome for all participants in this market.
Several key economic indicators released before Sep 28, 2026 could significantly impact this market. These include employment data, inflation reports, and manufacturing indices. Unexpectedly strong or weak readings in these areas could shift trader sentiment and lead to price fluctuations. Additionally, any statements from Federal Reserve officials regarding monetary policy or the economic outlook could also influence trading activity. Geopolitical events or unexpected shocks to the global economy could also play a role in moving this market, as they could affect overall economic confidence and expectations.
