Musk vs. OpenAI in Court: What the $
5 Min. Read Time
On April 28, 2026, the opening statements in the Musk vs. OpenAI case began at the US District Court in Oakland. At stake are $130 billion in damages, the future of OpenAI’s governance, and a question with direct relevance to the Mittelstand: How reliable is the structure behind the AI provider that companies have tied their workflows to?
The Essentials at a Glance
- $130 billion lawsuit. Musk is suing OpenAI, Sam Altman, Greg Brockman, and Microsoft. Key demand: Reversion to the non-profit structure and dismissal of the board.
- Governance under pressure. OpenAI’s legal form is being contested in court while an IPO is being prepared in parallel. Both have implications for the product and pricing model.
- Multi-provider strategy is a must. Relying exclusively on OpenAI means concentration risk. Contract clauses and exit scenarios deserve attention now.

What’s being debated in Oakland
Judge Yvonne Gonzalez Rogers – known from the Epic Games vs. Apple case – is presiding over the trial at the Northern District of California. The lawsuit has multiple strands. Musk’s lawyer Steven Molo (law firm MoloLamken) accuses OpenAI, Altman, Brockman, and Microsoft of systematically hollowing out the non-profit structure. Microsoft is also a co-defendant, with the allegation being “Aiding and Abetting Breach of Charitable Trust.”
The chronology is straightforward. Musk joined OpenAI as one of the founders in 2015 and invested at least $44 million according to his own statements. In 2018, he left the board after an internal power struggle. In 2019, OpenAI founded a for-profit subsidiary. In 2025, it followed with a restructuring into a Public Benefit Corporation under an OpenAI Foundation. In parallel, OpenAI is preparing an IPO that could take place this year.
The positions in the courtroom are far apart. Molo speaks of targeted enrichment and breach of principles. OpenAI’s lawyer Bill Savitt counters that Musk is suing as a disappointed founder and direct competitor with his AI company xAI. The judge had already reprimanded Musk before the trial because he had publicly attacked Altman and Brockman on his platform X. Both sides have agreed to limit their posts on the ongoing proceedings.

Why medium-sized businesses should take a closer look
For companies that are productively using ChatGPT Enterprise, the OpenAI API, or the Microsoft Copilot Stack, this process is about planning certainty.
Three scenarios are on the table. OpenAI remains in its current structure as a Public Benefit Corporation and goes public. Then shareholder interests will influence product policy and pricing. API prices could rise if the margin needs to be right. Second scenario: The court orders a return to the non-profit structure. Unlikely, but with consequences for existing contracts. Third scenario: A settlement with governance requirements that formally confirms the current structure but creates new transparency obligations.
The dependency goes further than many IT departments have documented. ChatGPT Enterprise accounts, API calls in internal workflows, Copilot functions via Microsoft 365 – the OpenAI stack is more deeply embedded in many companies than the last vendor audit captured. An IPO shifts the incentives: shareholders optimize for returns. A structural change could affect enterprise agreements. And a settlement sends the signal that the governance behind the product was less solid than assumed.
„We’re here because Mr. Musk now competes with OpenAI. Because he’s a competitor, Mr. Musk will do anything he can do to attack OpenAI.“
– Bill Savitt, OpenAI lawyer (Opening Statement, April 28, 2026)
What should be on the agenda now
IT managers and CEOs should review three points.
First: Contract clauses in the event of a structural change. Enterprise contracts with OpenAI typically contain standard SaaS terms. Change-of-control clauses are often missing. As long as the process is ongoing and OpenAI prioritizes customer loyalty, this can be renegotiated.
Second: Evaluate a multi-provider strategy. Anthropic Claude, Google Gemini, Mistral, and open-source models like Llama 3 have reached a level of performance in 2026 that makes switching providers a realistic option. A second provider in the stack reduces legal risk and creates a negotiating position.
Third: Map internal dependencies. How many processes are directly dependent on OpenAI APIs? Which of these are business-critical? The honest answer is more uncomfortable than expected in most companies. That’s exactly why it’s worth doing now, before a verdict or an IPO prospectus forces the question.
The outcome of the process is open. Preparation for it lies with the companies themselves.
Frequently Asked Questions
What exactly is Musk demanding in his lawsuit?
$130 billion in damages in favor of the OpenAI Foundation, the return of OpenAI to a non-profit structure, and the removal of Sam Altman and Greg Brockman from the board. Microsoft is named as an accomplice (“Aiding and Abetting Breach of Charitable Trust”).
Will the lawsuit have a direct impact on existing ChatGPT Enterprise contracts?
Not in the short term. In the long term, it depends on the outcome. A court-ordered structural change could affect contract terms. More relevant to pricing is the parallel IPO preparation, which is running independently of the lawsuit.
How long is the lawsuit likely to take?
A precise prediction is difficult. Comparable lawsuits in the US have dragged on for months or even years. A settlement could significantly shorten the process, but so far, neither side has signaled a willingness to settle.
