Palantir CEO Alex Karp made waves on Thursday when he said AI companies pushing for regulation are really trying to escape liability, not protect the public.

Karp appeared on CNBC’s Squawk on the Street and went straight for the jugular. “The first line of defense is you’re liable for your own actions,” he said.
PLTR stock was trading up around 0.6% to $175.35 at the time, and has gained roughly 5% this week.
Palantir Technologies Inc., PLTR
Karp’s argument is simple: if AI leaders genuinely believe the technology is dangerous, they should stop building it. Asking for government regulation instead, he says, is a way to avoid being held personally responsible.
“What is the liability risk for destroying 10% of the world?” Karp asked on air.
He went further, suggesting that some frontier AI labs may ultimately need to be nationalized. His reasoning: if those companies continue absorbing business data and intellectual property while avoiding liability, the U.S. government becomes the only entity that can shield them from mass lawsuits.
“These businesses have to be nationalized because if you don’t nationalize it, every single one of my clients is going to sue,” Karp said.
Data and IP Concerns
Karp also raised concerns about what closed AI models do with customer data. He said businesses using closed models and paying for tokens could be unknowingly handing over their intellectual property to model providers.
He argued that discounted token pricing isn’t just a growth strategy. It can also give AI companies access to customer data that helps improve their own models.
Karp linked this to what he called the “sovereignty revolution,” which he said Palantir helped launch alongside Nvidia CEO Jensen Huang. The idea is that companies using open models, combined with their own application layer, can keep greater control over their data and technology.
Where the AI Debate Stands
Karp’s comments land in the middle of a very public divide in the tech world.
On one side, Anthropic CEO Dario Amodei, OpenAI CEO Sam Altman, and SpaceX’s Elon Musk have called for a slower pace of AI development. Karp said he has “a lot of respect” for Amodei, calling him both an ethical entrepreneur and a businessperson.
On the other side, Meta CEO Mark Zuckerberg and Nvidia CEO Jensen Huang have pushed back against curbing development. Zuckerberg posted on X: “Any lab that doesn’t focus on alignment will fall behind.”
Microsoft CEO Satya Nadella has taken a middle position, stressing that humans must stay in control of AI. Microsoft also released a new code of conduct this week for how it trains and operates its AI models.
OpenAI disclosed six new cases of unexpected model behavior in the last six months. A breach involving Hugging Face has added more fuel to the AI safety debate.
Karp’s final word on Thursday: “We need to get serious.”
