How Nvidia and Meta just killed a White House plan to ban Chinese AI models

A quiet but ferocious lobbying war inside Silicon Valley just reshaped U.S. policy toward Chinese AI. The Trump administration, prodded by OpenAI and Anthropic, spent weeks weighing sanctions, trade blacklists, and even a ban on U.S. cloud companies doing business with makers of Chinese open-weight models like Moonshot AI’s Kimi K3. The New York Times reports that White House Chief of Staff Susie Wiles, Treasury Secretary Scott Bessent, and Commerce Secretary Howard Lutnick were all in the room. Bessent floated sanctions on the same day that White House science advisor Michael Kratsios accused Moonshot of distilling Anthropic’s Claude model, calling the alleged theft “unacceptable.”

Then the counter-offensive began. Nvidia, Meta, Microsoft, and Google — companies with massive ecosystems built on open-weight models — saw the push as an existential threat dressed up in national security language. Through private messages, calls, and video conferences, they built a case that open models accelerate innovation and cyber defense, not just Chinese competition. Nvidia CEO Jensen Huang broke his social media silence on July 24 with his first-ever post on X to defend open models, while the company’s security tools alliance ballooned from a handful of members to over 230.

The argument that won the day wasn’t ideological; it was practical and self-interested. Christopher Padilla, a former Commerce Department official, told the NYT the dispute is a “cage fight over the future of the AI industry” — mostly about money and market power, with the security angle tacked on. OpenAI and Anthropic, both planning IPOs, stood to lock in a regulatory moat if the White House cracked down on open-weight rivals. Their opponents saw that as a business power grab and fought back accordingly. The administration backed off. No hard measures are expected before Chinese President Xi Jinping’s visit in September.

For now, the White House is pivoting to making U.S. models more competitive rather than banning Chinese ones. That’s a direct win for the open-weight camp, but the fight isn’t over. The same tensions will resurface the next time a Chinese model matches or beats American benchmarks. Underneath the policy drama is a structural reality that no administration has resolved: closed models concentrate power in a few labs, open models spread it, and the national security implications cut both ways. What’s clear is that the industry’s biggest players can still redirect Washington’s hand when they agree on something — even if they agree on almost nothing else.
