Palantir CEO Alex Karp went on CNBC’s Squawk Box last week to discuss a new partnership with Nvidia to deploy open-weight AI models in sovereign government environments. But viewers got a nearly 20-minute broadside against the entire frontier AI model industry, calling it “effing insane” and accusing companies like OpenAI and Anthropic of overcharging enterprises while harvesting their proprietary data.

Days later, Mistral CEO Arthur Mensch made a strikingly similar case on LinkedIn, warning that closed AI providers are gaining “immense leverage” over enterprise customers as organizations connect proprietary workflows to hosted models. He suggests open-weight models, open data systems, and enterprises building their own training flywheels.

As TNS contributor Amanda Caswell writes, the two executives are approaching this from opposite ends of the market, yet their convergence on the same message within the same week underscores architectural control.
