This market will resolve to the number of weekly active users (WAU) of OpenAI's products.

The question will be resolved based on official reports by OpenAI if available, by the end of January 2026. If official reports are unavailable, resolves based on a media reports as available at the end of January 2026. If no such reports are available, the deadline will be extended to February 2026. (If I still can't find decent numbers by the end of February, the question will N/A.)

ChatGPT uses will be assumed to be equal to OpenAI users unless a report/source explicitly notes the difference.
