## Summary

OpenEvidence reports that nearly two‑thirds of roughly ~1 M U.S. physicians are using its AI‑powered search engine, which is funded by advertisements. The company’s founder highlighted the adoption rate in a recent interview, but the figure has not been independently verified.

A source close to the business, speaking on condition of anonymity, says the platform is on track to generate between $400 million and $500 million in ad revenue by 2026. The source did not disclose how the estimate was calculated. The ad‑supported model has sparked discussion about how commercial incentives might affect clinical decision‑making and patient care, with some clinicians expressing concern.

OpenEvidence has not provided detailed usage metrics beyond the headline claim, and the revenue projection remains speculative pending market conditions and advertiser interest.

## Key points

- OpenEvidence claims nearly two‑thirds of ~1 M US physicians use its AI search engine.
- The ad‑supported tool is projected by a source to earn $400 M‑$500 M in revenue by 2026.
- Both usage and revenue figures are unverified and based on company and source statements.

## Why it matters

Widespread AI search use in clinical settings could reshape information access, while ad‑funded models raise questions about influence on patient care.
