Elon Musk’s lawsuit could be the least of OpenAI’s problems—shedding its nonprofit status will cost a fortune

A good rule of thumb in life is to never get on the bad side of a litigation-happy centibillionaire with a Rolodex of law firms at his beck and call.

But Elon Musk’s second lawsuit against OpenAI, to whom he made charitable donations amounting in total to more than $50 million, may be the least of its immediate concerns. There is one authority that still has greater resources at its fingertips than the man tipped to be the world’s first trillionaire — the government.

And it can make OpenAI’s life hell if it chooses to investigate and prosecute any missteps as the ChatGPT creator attempts to shed its nonprofit shell and emerge as a public benefit corporation capable of one day enriching its shareholders.

In fact, the state is really the only entity capable of pursuing legal measures to ensure nonprofits don’t cheat the system. And in a matter of weeks the levers of government power will be in the hands of close Musk ally, Donald Trump.

“If I was OpenAI and you asked me what should worry me more,” Luís Calderón Gómez, an assistant professor at Yeshiva University’s specializing in tax policy, tells Fortune, “it wouldn’t be Musk’s lawsuit, it would be the conversion.”

In a statement to Fortune, OpenAI chair Bret Taylor pledged the nonprofit board would honor its fiduciary obligation by ensuring the company remains well-positioned to fulfill its stated mission.

“While our work remains ongoing as we continue to consult independent financial and legal advisors,” he said, “Any potential restructuring would ensure the nonprofit continues to exist and thrive, and receives full value for its current stake in the OpenAI for-profit with an enhanced ability to pursue its mission.”

Open-AI's for-profit subsidiary is already valued at $157 billion

The stakes are unusually high for the otherwise sleepy sector of U.S. nonprofits, estimated to account for $3.3 trillion of America’s annual economic output. Despite its significance as the company behind the boom in generative artificial intelligence, an IRS filing this week from OpenAI reveals just how little value is actually assigned to the nonprofit.

Thanks to the goldrush triggered by the commercial launch of ChatGPT nearly two years ago, a recent fundraising round valued OpenAI Global, LLC, the operating company, at a staggering $157 billion. Earlier this year one of Asia’s foremost experts in the field, Kai-fu Lee, even suggested it could make history as the first privately-held company worth $1 trillion.

For all intents and purposes, it operates like a normal company, counting Microsoft alongside Khosla Ventures and LinkedIn co-founder Reid Hoffman as major investors.
