These markets track the not seasonally adjusted Consumer Price Index for All Urban Consumers in July 2026, measuring the overall price level of goods and services across the U.S. economy. Each market resolves based on whether the CPI-U index value exceeds a specific threshold, with thresholds ranging from 333.6 to 335.8 in 0.2-point increments.
Resolution is determined by the not seasonally adjusted Consumer Price Index for All Urban Consumers: U.S. city average, All items (1982–84=100) for July 2026. The underlying data source is the Bureau of Labor Statistics' Consumer Price Index News Release Table 1, specifically the "All items" value under the "Unadjusted indexes" column. Each market outcome corresponds to a specific threshold level: 333.6, 333.8, 334.0, 334.2, 334.4, 334.6, 334.8, 335.0, 335.2, 335.4, 335.6, and 335.8. A market resolves to Yes if the published CPI-U index value exceeds its designated threshold. Resolution uses the first value published by the Bureau of Labor Statistics in the scheduled Consumer Price Index release for July 2026; subsequent revisions do not affect the outcome.
Prediction market odds and professional analyst forecasts often diverge because they reflect different methodologies and incentive structures. Traders in this market are putting real capital at risk, which can sharpen their forecasts but may also introduce short-term noise. Analyst surveys typically aggregate expert opinion and historical models, while market prices incorporate live information and trader conviction. Comparing the two reveals whether the crowd is more or less bullish on inflation than the consensus view, helping you identify potential surprises or areas of broad agreement.
On Kalshi, this market is priced through a continuous order-book mechanism where buyers and sellers post bids and offers on specific inflation outcomes. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Traders profit by correctly predicting the July CPI-U reading, and the market price reflects the collective probability assigned by all active participants. As new economic data, Fed communications, or employment reports surface, traders adjust their positions, moving the odds in real time. This dynamic pricing ensures the market continuously incorporates the latest available information.
This market resolves around Aug 19, 2026, once the July CPI-U data is officially released and verified. The outcome is determined by comparing actual inflation readings against the prediction market's predefined outcome brackets. Resolution happens after credible public reporting confirms the final figure, ensuring all traders have access to the same authoritative information. Until that point, odds will fluctuate as traders react to economic indicators, Fed policy signals, and other inflation-relevant developments.
Several catalysts can shift odds significantly before resolution. Employment reports, retail sales data, and producer price indices all feed into inflation expectations and can trigger sharp repricing. Federal Reserve communications, interest rate decisions, and forward guidance shape how traders view price pressures ahead. Commodity price swings, particularly in energy and food, often drive near-term volatility. Geopolitical events or supply-chain disruptions can also move the needle. Traders typically react most sharply to data releases that directly inform the CPI calculation or signal broader economic momentum.
