Nvidia is bolstering support for Chinese open AI models as it warns of White House crackdown

Nvidia is bolstering support for Chinese artificial intelligence models in a play to beat domestic chipmakers to optimizing hardware for the systems. The move comes amid growing unease among U.S. lawmakers about the adoption of Chinese AI models by American companies.

The chip giant on Wednesday highlighted a “local AI initiative with optimizations for top open models,” including DeepSeek’s V4 Flash and Alibaba’s Qwen 3.8, alongside systems developed by Google and Nvidia itself.

But an SEC filing linked to the company’s second-quarter earnings also warned of business risks from potential White House restrictions on AI developed in China.

Chinese AI models have made leaps in capability in 2026 and their increasing adoption by developers across the globe — including in the U.S. — has intensified a wave of anxiety from lawmakers in Washington.

Access to open AI models, the most capable of which are Chinese, has become a key flashpoint in the intensifying race for technological supremacy between the U.S. and China. Open AI models can be modified and self-hosted, in contrast to leading closed systems produced by OpenAI and Anthropic.

Both Beijing and Washington have looked to leverage political heft to gain an advantage, with a report emerging on Thursday that U.S. President Donald Trump’s administration is considering new tariffs on U.S. semiconductors.

A White House official told CNBC that “unless officially announced by the Administration, any reporting about tariffs should be regarded as baseless speculation.”

The U.S. is also mulling restrictions that would limit Nvidia’s ability to support “third-party applications and models built on open-source foundation models originating in China,” the company said, reiterating messaging in previous earnings.

It warned that any “regulatory control or other restriction that limits our ability to provide products and services” supporting apps built on models “such as DeepSeek, Qwen or Kimi” could have a material impact on business.

Nvidia shares rose on Thursday after the company reported better-than-expected second-quarter results and issued revenue guidance that topped estimates. The tech giant, which holds a near monopoly over the most advanced AI chips, has seen its stock rise more than 10% so far in 2026.
