Why Musk’s OpenAI lawsuit now centers on up to $134B

Elon Musk’s legal fight with OpenAI and Microsoft now includes a damages claim ranging from $79 billion to $134 billion. Newly released documents and testimony focus attention on OpenAI’s nonprofit origins, early discussions about a for-profit structure, and competing claims about who supported that shift.

The story is mostly a legal and business dispute, with only a mild Terminator lean because it concerns control of a powerful AI organization and its mission.

Why Musk’s OpenAI lawsuit now centers on up to $134B

The dispute between Elon Musk and OpenAI has moved beyond a fight over business strategy. Thousands of pages of documents and testimony have put OpenAI’s original nonprofit mission, its later structural changes, and Musk’s own role in those discussions under scrutiny.

At the center is a damages claim that could reach $134 billion. Musk’s side argues that his early support was tied to a mission that OpenAI later betrayed. OpenAI argues the record tells a more complicated story, including Musk’s own support for a for-profit component inside the OpenAI ecosystem.

A damages claim tied to OpenAI’s valuation

Musk’s attorney Steven Molo, via Bloomberg, is seeking $79 billion to $134 billion in damages from OpenAI and Microsoft. The claim breaks down into $65.5 billion to $109.4 billion from OpenAI and $13.3 billion to $25 billion from Microsoft.

The argument is built around Musk’s $38 million in seed funding. His side claims he was defrauded and should receive a corresponding share based on OpenAI’s current $500 billion valuation.

The number may not be fixed. The source article states that if the valuation climbs to $750 billion before the April trial, the damages claim is expected to rise too.

That makes the case more than a backward-looking argument over OpenAI’s founding ideals. It also turns OpenAI’s current market value into a central part of the fight.

The nonprofit question now facing the court

The major issue is whether OpenAI used its nonprofit status to gain advantages while its leadership was already planning a commercial pivot. The source frames those possible advantages as reputation, recruiting, and tax benefits.

That question is difficult because the documents show tension rather than a simple timeline. OpenAI launched with a nonprofit mission, but questions about long-term funding and structure appeared early.

The founders, including Musk, discussed in 2017 how a transition could be explained without damaging the nonprofit’s moral standing. Musk wrote: "must tell the story and not lose moral high ground. absolutely vital."

That line matters because it suggests the founders were not only debating structure. They were also debating how the change would be understood by people who believed in the nonprofit mission.

Documents complicate Musk’s position

Musk argues that OpenAI betrayed the nonprofit mission he helped fund. But the source article says early interview notes show he agreed to adding a for-profit unit in 2017 while keeping the nonprofit in place.

According to OpenAI, Musk founded a Public Benefit Corporation within the OpenAI ecosystem in 2017. OpenAI describes that as a for-profit structure similar to what it uses today with OpenAI Group PBC under nonprofit control.

OpenAI also claims Musk’s lawyers "cherry-picked" court filings and left out important context. The company says negotiations did not break down because OpenAI could go commercial. Instead, OpenAI claims they collapsed because Musk demanded complete control and majority ownership.

OpenAI calls the lawsuit "unserious" and describes it as a "harassment campaign." Those claims are part of OpenAI’s effort to present the case as a dispute over control rather than a clean story of a nonprofit mission being abandoned.

Testimony adds another layer

Co-founder Greg Brockman’s testimony also highlights the tension between mission and money. His notes included the question, "Financially, what will take me to a billion dollars?"

When asked about that note, Brockman called financial incentives under a for-profit structure a "secondary consideration." He said the more important issue was whether OpenAI’s nonprofit mission could be fulfilled.

That testimony cuts to the heart of the dispute. The court is being asked to examine whether a for-profit structure was a tool for achieving the mission, or evidence that the mission had already been compromised.

The answer is not obvious from the documents described in the source. The record includes early nonprofit commitments, early discussions about funding limits, and early conversations about adding a commercial structure.

How the timeline shapes the case

The timeline is central to both sides. Musk backed the creation of OpenAI, invested $38 million in seed funding, and later left OpenAI’s board in 2018.

OpenAI claims Musk proposed folding the company into Tesla. It also says that when he left, he told OpenAI to raise "billions" on its own or gave the project "zero percent" chance of success.

Musk founded xAI in 2023 and filed the lawsuit in 2024. The trial is set for late April 2026 in California.

For OpenAI, those facts support the argument that Musk understood the funding problem and the possibility of a for-profit structure. For Musk, the case remains focused on whether OpenAI’s later path violated the nonprofit mission that attracted his early support.

The released evidence does not reduce the dispute to a single question of corporate form. It raises a broader issue: whether OpenAI’s nonprofit identity was a durable commitment, a governance structure that evolved under funding pressure, or a public promise that now sits at the center of one of the most consequential AI lawsuits.
