Pentagon official overseeing military AI sold millions worth of stock in AI firm 五角大楼负责军事AI官员出售数百万美元AI公司股票

TL;DR

• Emil Michael, the Pentagon official overseeing military AI policy, sold Perplexity holdings worth $5M–$25M in June 2025, shortly after cashing out $24M in xAI stock earlier that year
• Michael previously held a personal loan from Perplexity ($250K–$500K at 4.57% interest), served on its advisory board, and appeared on a Brex-sponsored podcast while still an investor in the company
• His Brex holdings surged from a maximum reported value of $750K in March 2025 to a sale price of at least $5M in April, representing gains of at least 473%
• Ethics experts criticize the timing and scale of these trades, arguing all interests should have been divested before assuming federal service, though the Pentagon maintains full compliance with ethics laws

Why It Matters

This case highlights the growing tension between rapid AI industry growth and government oversight, as officials with direct policy influence over AI companies simultaneously profit from those same firms. It raises serious questions about conflicts of interest in the intersection of defense policy and private AI investment, potentially undermining public trust in military AI governance.

Technical Details

• Michael's Perplexity stake included both vested and unvested shares; his ethics agreement explicitly prohibited profiting from unvested stock, though disclosures do not clarify which portion was sold
• Perplexity, an AI-powered search engine, recently sought a $30B valuation and holds a contract with the US General Services Administration, though no direct Pentagon ties are documented in the records
• xAI investment yielded returns between 400% and 4,800% on a private placement made before Michael's federal appointment, with the sale occurring in January 2025
• Brex, a financial software company backed by Peter Thiel, was acquired by Capitol One in April 2025; Michael's role as a former consultant and ongoing podcast appearance while an investor adds further conflict concerns

Industry Insight

• The Trump administration's defense AI leadership should establish stricter pre-appointment divestiture requirements to avoid even the appearance of conflicts, setting a precedent for future tech-government revolving door cases
• AI companies like Perplexity and xAI should scrutinize the backgrounds of government officials they engage with, as close ties can create regulatory and reputational risk when those officials profit from their positions
• Lawmakers may introduce new ethics legislation targeting AI sector insiders entering government roles, given the concentration of personal wealth gains among officials overseeing AI policy and regulation

摘要

埃米尔·迈克尔（Emil Michael）——负责监督军事AI政策的五角大楼官员——于2025年6月出售了价值500万至2500万美元的Perplexity股票，而在此前几个月，他刚刚套现了2400万美元的xAI股票。

迈克尔此前曾从Perplexity获得个人贷款（25万至50万美元，利率4.57%），担任其顾问委员会成员，并在仍持有该公司股份期间参加了由Brex赞助的播客节目。

他的Brex持股从2025年3月报告的最高价值75万美元飙升至4月至少500万美元的售价，涨幅至少达473%。

伦理专家批评这些交易的时间和规模，认为所有利益关系都应在接受联邦职务前剥离，尽管五角大楼坚称完全遵守伦理法规。

极简总结

• 埃米尔·迈克尔，负责监督军事AI政策的五角大楼官员，于2025年6月出售了价值500万至2500万美元的Perplexity股票，而在此前几个月，他刚刚套现了2400万美元的xAI股票。
• 迈克尔此前曾从Perplexity获得个人贷款（25万至50万美元，利率4.57%），担任其顾问委员会成员，并在仍持有该公司股份期间参加了由Brex赞助的播客节目。
• 他的Brex持股从2025年3月报告的最高价值75万美元飙升至4月至少500万美元的售价，涨幅至少达473%。
• 伦理专家批评这些交易的时间和规模，认为所有利益关系都应在接受联邦职务前剥离，尽管五角大楼坚称完全遵守伦理法规。

为何重要

此案凸显了AI行业快速增长与政府监管之间日益加剧的紧张关系：拥有AI公司直接政策影响力的官员，同时从这些公司获利。这引发了关于国防政策与私人AI投资交叉领域利益冲突的严重质疑，可能损害公众对军事AI治理的信任。

技术细节

• 迈克尔的Perplexity持股包括已归属和未归属的股票；他的伦理协议明确禁止从未归属股票中获利，尽管披露文件未明确说明出售的是哪一部分。
• Perplexity是一家AI驱动搜索引擎，近期寻求300亿美元估值，并持有美国总务管理局的合同，但记录中未显示与五角大楼的直接关联。
• xAI投资在迈克尔联邦任命前进行的私募中产生了400%至4800%的回报，而
