Consumer Price Index (CPI)
The Consumer Price Index measures the average change in prices paid by urban consumers for a basket of goods and services. As the headline U.S. inflation gauge, each CPI print moves rate expectations, bond yields, and equity risk appetite.
Why prediction-market odds belong next to this release
Alongside the official CPI series we overlay the implied probability from Kalshi and Polymarket — the market's own forecast for the upcoming print, pulled live through kitalpha-api. A binary contract trading at 62¢ implies a 62% probability of that outcome.
These macro markets have become a genuine real-time forecast, not just a sideshow. The Federal Reserve's Finance and Economics Discussion Series paper FEDS 2026-010, “Kalshi and the Rise of Macro Markets,” documents how venues like Kalshi increasingly lead the macro narrative — frequently pricing in surprises ahead of, and more sharply than, traditional survey-based consensus.
