OpenAI's chief financial officer has reportedly said that 300M people use ChatGPT for health-related purposes and 200M use it for finance, according to a FourWeekMBA report published on 07 November 2026.

The figures point to substantial reported use of ChatGPT in two sensitive fields. details about the underlying measurement, the period covered or whether the figures represent unique people or usage occasions is not yet available.

What the reported figures show

The report identifies health and finance as separate areas of ChatGPT use. It gives a figure of 300M for health and 200M for finance.

The available information does not specify what activities are included in either category. It also does not say whether the figures refer to people using ChatGPT directly, organisations using the service, or a broader estimate of activity.

Those distinctions matter when interpreting the numbers. A usage figure can reflect repeated interactions rather than a count of distinct individuals, but the supplied report does not clarify the methodology.

Why the figures matter

Health and finance involve information that can affect personal decisions. The reported adoption figures therefore raise questions about how users rely on ChatGPT in these areas, although examples, safeguards or policy details is not yet available.

The figures should be treated as attributed claims rather than independently verified user totals. No supporting dataset, methodology or additional statement from OpenAI is included in the available material.

Conclusion

The FourWeekMBA report attributes figures of 300M health users and 200M finance users to OpenAI's CFO. More information is needed to determine how those figures were calculated and what they represent.
