Two members of U.S. Congress are calling on President Donald Trump's administration to consider restricting the export of artificial intelligence chips made by Nvidia , alleging Chinese AI firm DeepSeek has relied on them.

DeepSeek’s AI models reportedly rival OpenAI’s for a fraction of the cost and compute.

American AI stocks got sucker punched after China's DeepSeek app reportedly showed advancements against rivals sending investors into sell mode, shaving 3% off the Nasdaq.

In a surprising twist, Deepseek's cost-effective AI solution has rattled the stock market, raising eyebrows and sparking intense scrutiny from U.S. officials.

DeepSeek stunned the tech world with the release of its R1 "reasoning" model, matching or exceeding OpenAI's reasoning model for a fraction of the cost.

NVIDIA, the world's most valuable company until Monday, lost $600 billion of market value in a single day, the biggest in US stock history.

US officials are deep into an investigation to find out if Chinese AI startup DeepSeek found a backdoor route to Nvidia’s high-end chips through Singapore, evading American export bans.

Export controls need to be tightened after revelations the Chinese company used Nvidia technology, the leaders of a congressional committee said.

U.S. President Donald Trump's administration is considering tightening restrictions on artificial intelligence leader Nvidia's sales of its H20 chips designed for the China market, Bloomberg News reported on Wednesday.
