Recent Divestitures by the Pentagon’s AI Policy Lead
Emil Michael, the senior Pentagon official responsible for military artificial-intelligence policy, has disclosed the sale of sizable holdings in two private technology firms. Federal financial records indicate that in June he sold shares in Perplexity, an AI-powered search engine, for a value reported between $5 million and $25 million. Earlier this year he realized a gain of up to $24 million from his private investment in Elon Musk’s xAI, a profit range of 400 % to 4,800 % according to the same filings. In April, Michael also sold his stake in Brex LLC, a financial-software company backed by Peter Thiel, for an amount estimated between $5 million and $24 million, representing a gain of at least 473 % from the $750,000 valuation he reported in March 2025.
Financial Context and Prior Ties
Michael’s disclosures reveal a personal loan from Perplexity of $250,000-$500,000 at a 4.57 % interest rate, received a year earlier, and a brief advisory-board role that he left upon entering federal service. Some of his Perplexity stock was vested, some unvested, and his ethics agreement prohibited profit from the unvested portion. The company announced a contract with the General Services Administration in November of the previous year, though no direct Pentagon link appears in the records.
Ethics Concerns and Official Responses
Painter added that while the ownership may not violate law, it raises appearance concerns.
Implications for Defense-Tech Oversight
Michael’s trading activity, which also includes a podcast appearance on the tech show *Sourcery* sponsored by Brex while he remained an investor, highlights potential conflicts between personal financial interests and the stewardship of emerging defense technologies. The disclosures have prompted broader debate over the adequacy of existing ethics safeguards for senior officials overseeing rapidly evolving AI programs.
