Description

This event tracks changes in the cost of airline travel for average U.S. consumers over a specific month. It reflects how economic factors and industry conditions influence travel expenses, providing insight into broader inflation trends within the transportation sector.

Kalshi

The event evaluates whether the Consumer Price Index for All Urban Consumers: Airline Fares in the U.S. City Average for August 2026 exceeds various threshold values ranging from 310 to 336. Each market corresponds to a specific numerical threshold, and the outcome for each market is determined by comparing the published, seasonally adjusted index value to its respective threshold. If the index value for the specified month is above the threshold defined for a given market, that market resolves to Yes; otherwise, it resolves to No. All markets rely on the same official data source, the Federal Reserve Economic Data (FRED) series CUSR0000SETG01, which is released monthly and provides a consistent, standardized measure of airline fare inflation for the designated period.
