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.
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.

Comparing prediction market odds to analyst forecasts reveals how collective intelligence differs from expert opinion. Often, this market demonstrates a unique perspective, potentially incorporating a wider range of factors than traditional analysis. While analysts might focus on specific growth metrics or marketing campaigns, the market aggregates the views of many participants, reflecting a broader assessment of potential outcomes. Discrepancies can highlight overlooked risks or opportunities, offering a valuable counterpoint to conventional wisdom about the ChatGPT app's adoption rate.
On Kalshi, this market is priced through a continuous double auction, where traders buy and sell contracts representing different outcomes for the total number of ChatGPT app downloads in October. The price of each contract reflects the market's assessment of its probability. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. As more traders participate, the prices adjust to reflect the evolving consensus. This dynamic pricing mechanism allows the market to quickly incorporate new information and adjust expectations about the final download numbers. The current prices indicate the collective belief of traders regarding the likelihood of each outcome.
This market resolves around Nov 15, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The final number of ChatGPT app downloads in October will be sourced from publicly available data, ensuring a transparent and objective resolution. The market will then determine which outcome corresponds to the verified download count. 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. Unexpected news related to competitor apps or broader trends in the AI space could also shift sentiment. Furthermore, any reports on user adoption rates or marketing campaign effectiveness could impact trading activity. Positive or negative press coverage, viral social media trends, or even significant changes in app store policies could all contribute to price fluctuations in this market.
