- Elon Musk amended his lawsuit against OpenAI and Microsoft, redirecting any potential damages — estimated at more than $150 billion — to OpenAI’s original charitable foundation rather than to himself.
- Musk’s attorney Marc Toberoff confirmed that Musk “is not seeking a single dollar for himself,” reframing the suit as a charitable enforcement action.
- The amended complaint demands the removal of CEO Sam Altman from the foundation’s board and asks the court to require both Altman and President Greg Brockman to surrender their equity and financial benefits to the foundation.
- The trial is scheduled to begin in April 2026 in Oakland, California; OpenAI, valued at $852 billion and planning an IPO, has asked state attorneys general to investigate Musk’s conduct.
What Happened
Elon Musk filed an amended complaint in his ongoing lawsuit against OpenAI and Microsoft, restructuring the relief he is seeking so that any potential damages — estimated by his legal team at more than $150 billion — would go to OpenAI’s original charitable foundation rather than to Musk personally. Marc Toberoff, Musk’s attorney, told the Wall Street Journal that Musk “is not seeking a single dollar for himself.” The development was reported by The Decoder on April 9, 2026.
The amendment marks a tactical shift in how the lawsuit is framed publicly. By directing any damages to the foundation, Musk’s team positions the suit as an effort to restore value to the nonprofit entity rather than as personal financial recovery — a distinction that may affect judicial reception and public perception of the case. The trial is scheduled to begin this month in Oakland, California.
Why It Matters
OpenAI is currently valued at $852 billion and is planning an initial public offering, making the lawsuit’s outcome directly relevant to the company’s corporate restructuring timeline. The suit challenges the legal validity of OpenAI’s transition from a pure nonprofit to a capped-profit commercial entity, a structural change that requires regulatory sign-off from the attorneys general of both California and Delaware.
Musk’s amended filing arrives as OpenAI pursues its own legal escalation. The company has formally asked the attorneys general of Delaware and California to investigate Musk’s conduct in connection with the case, adding a regulatory dimension to the dispute beyond the courtroom proceedings.
Technical Details
The amended complaint seeks two specific forms of injunctive relief beyond monetary damages: removal of CEO Sam Altman from the OpenAI nonprofit foundation’s board, and a court order compelling both Altman and President Greg Brockman to surrender their equity stakes and financial benefits derived from the commercial entity to the foundation. Musk’s legal team contends that these benefits were improperly obtained by exploiting the nonprofit’s tax-exempt status and by defrauding early donors, including Musk himself.
The $150 billion figure represents Musk’s lawyers’ estimate of the value the nonprofit foundation was deprived of through the for-profit conversion. Microsoft, which has made substantial investments in OpenAI across multiple rounds since 2019, remains a named co-defendant. The central legal theory holds that OpenAI’s commercial growth to an $852 billion valuation was built on a nonprofit structure that early donors funded under different terms.
Musk’s claims are complicated by contemporaneous evidence cited in prior reporting: early interview notes indicate that Musk agreed to adding a for-profit unit in 2017 and participated in transition discussions while the nonprofit structure remained formally in place.
Who’s Affected
Altman and Brockman face the most direct consequences under the proposed relief — forfeiture of equity positions and removal from foundation governance — if a court rules in Musk’s favor. OpenAI’s broader investor base, which includes Microsoft as a major stakeholder, holds stakes tied to the planned IPO; unresolved litigation could complicate the regulatory approvals required for OpenAI’s conversion to a fully for-profit public benefit corporation.
OpenAI characterized the suit publicly as “a harassment campaign driven by ego, jealousy and a desire to slow down a competitor,” in a post on X. The company’s request for state-level attorney general investigations against Musk represents an escalation beyond courtroom proceedings, placing Musk’s own conduct under formal regulatory scrutiny.
What’s Next
The trial is scheduled to begin in April 2026 in Oakland, California, with both parties arriving after an extended pretrial period marked by competing legal escalations. OpenAI’s planned IPO and conversion to a public benefit corporation both require regulatory approvals that an active, high-profile trial could delay or complicate. Should a court grant Musk’s requested relief — requiring Altman or Brockman to surrender equity to the charitable foundation — the ruling would have no direct precedent in nonprofit-to-commercial conversion disputes in the technology sector.
