Description

This event tracks projected growth in ChatGPT app downloads for a specific month compared to the same month in the previous year. The index value represents the percentage change, with higher numbers indicating greater year-over-year increase. Participants assess whether download growth will meet or exceed various performance thresholds.

Kalshi

All markets resolve based on the Carbon Arc ChatGPT App Downloads index for October 2026, measured as year-over-year change relative to October 2025. An index value of 100 represents equal downloads compared to the prior year, with values above 100 indicating growth and below 100 indicating decline. Each market has a specific threshold: values above 80, 95, 100, 105, 110, 115, or 130 will resolve that market to 'Yes.' Determination occurs at 11:59 p.m. ET on the 7th calendar day following the end of October 2026, using finalized Carbon Arc data. Kalshi explicitly states no affiliation with the underlying company, and all trademarks remain property of their respective owners.

This process provides a clear and reliable determination of the market's result, based on real-world data and independent verification.

Several signals or events could significantly move this market before resolution. Major announcements regarding ChatGPT's features or availability, particularly those impacting app downloads, would be influential.
