Thrive Capital has invested approximately $1 billion in OpenAI at a $285 billion valuation, according to a source familiar with the matter. The investment marks a significant milestone in OpenAI’s ongoing fundraising efforts, which are expected to close in multiple phases. Thrive recently announced the closure of its latest fund, which exceeds $10 billion in commitments. OpenAI CEO Sam Altman, who has a close personal relationship with Thrive’s founder, Josh Kushner, praised the firm in a post on X. “Extremely grateful to work with Josh,” Altman wrote. “No one could ask for a more committed, more thoughtful, or harder-working investor.” Josh Kushner’s ties to U.S. political circles are well known. His father, Charles Kushner, serves as the U.S. ambassador to France, while his brother, Jared Kushner, was a senior adviser to former President Donald Trump and his son-in-law. These connections have drawn attention to the intersection of high-stakes tech investments and political influence. In December, OpenAI acquired an ownership stake in Thrive Holdings, a holding company that acquires and operates businesses it believes can be transformed by artificial intelligence. The financial details of that transaction were not disclosed. OpenAI’s latest funding round is structured to prioritize strategic investors first, including major technology companies like Nvidia, SoftBank, and Amazon, which are expected to contribute roughly 90% of the capital. After these initial commitments, the round will open to a broader group of institutional and private investors. The influx of capital underscores OpenAI’s continued momentum as it advances its AI models and expands its infrastructure. The company remains focused on building safe and scalable artificial general intelligence, with growing support from both the tech industry and high-profile investors.
