Court documents reveal OpenAI CEO Sam Altman holds over $2 billion in stakes across nine companies that have done business with the AI giant, intensifying allegations of self-dealing from Elon Musk, ten state attorneys general, and a U.S. congressional investigation.
The disclosure came Tuesday during hearings on Musk’s $150 billion lawsuit, which seeks Altman’s removal as officer and board member, citing breach of charitable trust and unjust enrichment. Altman has denied wrongdoing, stating he recused himself from key negotiations involving companies in his portfolio.
Major holdings include: $1.7 billion in fusion power firm Helion Energy, $633 million in fintech Stripe, and $258 million in anti-aging biotech Retro Biosciences. Smaller stakes exist in Cerebras, Lattice, Humane, Software Applications, and Formation Bio. Altman had previously sold his Reddit stake. Helion, yet to generate revenue, is valued at $5.4 billion privately.
Ten Republican state attorneys general have asked the SEC to examine OpenAI documents ahead of a potential IPO. Altman testified his involvement in the Helion deal was properly recused, “with board approval of final terms.”
