Palantir's Alex Karp argues OpenAI and Anthropic are heading for a wall of lawsuits — bad news for AI investors betting the model companies will swallow everyone else's data.

• Karp says investors are piling into the big AI labs on the assumption those labs will capture data from every company they touch.
• He thinks that assumption triggers lawsuits from his own clients, enough to break the business model.
• His conclusion: the model companies will end up nationalized because the legal liability is too big to carry privately.
• The jab at investors is blunt — if you think the companies handing over data are the suckers, you are the sucker.

Outlook: Expect more pressure on who owns the data feeding AI models, and a legal fight that investors in the big labs have not priced in.
