The Biden administration has forced a Saudi Aramco venture capital firm to sell its shares in a Silicon Valley AI chip startup backed by OpenAI co-founder Sam Altman, an exit that could have broader implications for the Middle Eastern country’s growing investments in US technology.

Prosperity7, a lead investor in a funding round that raised $25 million for Rain AI in 2022, sold its shares in the startup after a review by the Committee on Foreign Investment in the United States, people familiar with the matter said. The agency, the primary US watchdog for deals with national security implications, instructed the Saudi fund to unwind that deal sometime over the past year, the people said, asking to remain unidentified because the information is private.
