Big Tech Companies Split Over AI Rules

On July 24, 2026, Nvidia, Microsoft, Meta, Palantir, and 20+ companies signed a letter urging policymakers not to restrict "open-weight" AI — artificial intelligence whose inner workings are shared openly, like a published recipe anyone can read and modify. The group warned limits would "stifle competition or drive innovation overseas." OpenAI and Anthropic, both nearing $1 trillion valuations and preparing IPOs, did not sign, exposing a commercial divide within the AI industry itself.
