Kalshi
This market tracks whether the year-over-year Consumer Price Index will exceed 3.8% at any point during 2026. On Kalshi, the probability that CPI will breach this threshold stands at 99.0%. Resolution is determined by the Consumer Price Index YoY report published by the Bureau of Labor Statistics. Watch for the monthly CPI releases throughout 2026, as any single report showing inflation above 3.8% will trigger a Yes resolution by January 1, 2027.
Prediction market odds on Kalshi currently reflect probability for the top outcome, providing a real-time gauge of trader sentiment on CPI levels. Analyst forecasts and Federal Reserve projections typically rely on econometric models and historical data, while prediction markets aggregate dispersed information from many participants with financial incentives to forecast accurately. Comparing the two reveals whether markets are pricing in more or less inflation concern than professional economists, highlighting divergences in expectations about monetary policy, demand, and supply-side pressures.
On Kalshi, How high will CPI get this year is priced as a binary or range-based contract where traders buy and sell shares corresponding to different CPI outcome brackets. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The current odds reflect probability for the leading outcome. Pricing adjusts in real time as new economic data, Fed communications, and market sentiment shift trader positions. Higher CPI expectations push prices up; lower expectations push them down, creating a continuous market signal of inflation risk through Jan 1, 2027.
The How high will CPI get this year market resolves on Jan 1, 2027. Resolution is determined by the final CPI reading released for the specified period, which establishes whether the actual inflation level falls into the predicted range or outcome category. Official data from the U.S. Bureau of Labor Statistics serves as the authoritative source. Traders holding shares in the correct outcome receive payouts based on the final settlement price.
Key catalysts include monthly CPI releases, which provide real-time inflation data and often trigger sharp repricing. Federal Reserve policy announcements and interest rate decisions signal inflation-fighting intent and influence expectations. Employment reports, wage growth data, and commodity price movements all feed into inflation forecasts. Geopolitical shocks, supply chain disruptions, and energy price swings can rapidly alter CPI trajectories. Consumer spending reports and producer price indices offer leading signals. Each data release through Jan 1, 2027 will refine market odds as traders update their inflation outlook.
