Musk files injunction to block OpenAI's for-profit pivot

The legal war between Elon Musk and OpenAI just hit Round 4, and Musk is no longer waiting for a full trial to pull the emergency brake.

On late Friday, Musk’s legal team filed for a preliminary injunction in the U.S. District Court for the Northern District of California. The goal is straightforward: freeze OpenAI’s ongoing transition into a fully for-profit corporation and stop any transfer of material assets, including its intellectual property.

Expanding the battlefield to Microsoft

The injunction motion targets not just OpenAI, CEO Sam Altman, and President Greg Brockman, but also Microsoft, LinkedIn co-founder Reid Hoffman, and former board observer Dee Templeton.

Musk isn’t acting alone this time either. An amended complaint earlier in the month added his own startup xAI and Neuralink executive Shivon Zilis as co-plaintiffs.

The filing levels serious anticompetitive accusations against the AI giant. One major claim is that OpenAI is actively starving rivals of capital by demanding investor exclusivity.

Musk's lawyers noted that following reports in October about OpenAI asking backers to avoid competitors, at least one major funder in OpenAI’s October round subsequently declined to invest in xAI.

The motion also hits on alleged self-dealing and improper data sharing. It points out that OpenAI chose Stripe as its payment processor, a company where Altman holds a material financial interest and has reportedly made billions.

OpenAI fired back quickly. A spokesperson stated that Musk’s fourth legal attempt simply recycles baseless complaints and remains utterly without merit.

A ticking two-year clock

Musk’s attorneys argue that an immediate halt is the only way to prevent irreparable harm before the court can reach the merits of the case.

Their filing warns that OpenAI is currently burning over $5 billion a year and is nowhere near breaking even. If the court eventually rules in Musk’s favor, OpenAI might simply lack the funds to pay damages.

Furthermore, if the company continues to pull in billions under its current trajectory, unwinding those transactions down the road without causing catastrophic investor losses would be virtually impossible.

OpenAI also faces an external deadline. Reports from Bloomberg revealed that investors in its latest mega-round have the right to claw back their money if the company fails to convert to a for-profit entity within two years.

Even though xAI recently closed a $5 billion round and holds around $11 billion in the bank, Musk clearly smells blood in OpenAI’s structural vulnerability.

Why it matters

Musk’s latest maneuver is strategically brutal. For builders and enterprises relying on OpenAI, API services won't shut down tomorrow, but the operational ground beneath ChatGPT is getting shaky.

We think this injunction request strikes directly at OpenAI’s single biggest pressure point: the two-year deadline to restructure or face mass investor refunds. Freezing the transition now, even temporarily, could throw a wrench into OpenAI's $150 billion-plus valuation and shake investor confidence just when compute costs are skyrocketing.

Beyond corporate drama, the case puts Silicon Valley's informal power dynamics under judicial scrutiny. By attacking exclusivity pacts that bar VCs from backing rivals and highlighting intimate ties between Microsoft and OpenAI's leadership, Musk is testing the antitrust limits of modern AI partnerships.

It looks like OpenAI's hybrid nonprofit roots, once hailed as a moral safeguard, have turned into its most dangerous legal liability. If the court grants even a partial pause, it will dramatically reset the competitive timeline for the entire AI race.
