Shares of Nvidia and Advanced Micro Devices both fell more than 2% in early trading after The Wall Street Journal reported the federal government is weighing new restrictions on exports of sophisticated chips used in artificial intelligence computing to China.

The export restrictions under consideration would be imposed by the Commerce Department and would come after the U.S. government already limited the computing power of chips made for Chinese use. Nvidia and AMD had been impacted by the prior limitation.

Other chipmakers also fell on the news. Marvell and Broadcom both dropped less than 1%, while Qualcomm slipped more than 2%.

Nvidia responded to the earlier restrictions by building a lower-spec chip for the Chinese market. But under the new controls being considered, even that chip, the A800, would be export restricted without licensing, the Journal reported.

The restrictions would also apply to companies that offer cloud-based computing solutions, the Journal reported, which have been used by some companies to skirt export controls.

Competition between the U.S. and China over hardware and software technology has amplified in recent years. Cybersecurity threats from Chinese state-backed threats have been identified by top U.S. officials as one of the top national security threats facing the United States. Sensitive technology has allegedly been stolen from American companies to benefit Chinese domestic competitors, whether through outright industrial espionage or through joint-venture projects, which require American companies to partner with Chinese firms to do business within China.

Against this backdrop, tightened chip export controls would likely further inflame trade tensions between the two countries. U.S. officials have tried to mitigate potential impacts, but a tightening of export controls would likely jeopardize those efforts. Gina Raimondo, who as secretary of Commerce would lead the enforcement of any export controls, met with her Chinese counterpart in Beijing earlier this year.

Nvidia declined to comment, as did the Bureau of Industry and Security, which is the Commerce Department’s export control unit. AMD did not immediately respond to a request for comment.

Correction: The federal government is weighing further restrictions on exporting powerful computing chips to China, the kind that power AI models, The Wall Street Journal reported Tuesday. An earlier version misstated the day.

Bitcoin price rises as Israel-Iran ceasefire begins, and Senate unveils major crypto bill

Bitcoin price rises as Israel-Iran ceasefire begins, and Senate unveils major crypto bill

Crypto prices, including bitcoin, rose on Tuesday after President Trump announced a ceasefire between Iran and Israel.

By midday Tuesday, bitcoin had passed the $105,000 level, ether jumped back above the $2,400 mark, and XRP climbed to $2.19. 

The risk-on action in the markets, which also saw stocks rally on the Mideast de-escalation, wasn’t the only source of momentum, as Republican senators unveiled a major bill to set the rules of the road for crypto. Specifically, the legislation would define when crypto is a commodity or a security, allow crypto exchanges to register with the Commodity Futures Trading Commission, and reduce the Securities and Exchange Commission’s regulation of digital assets — a big reversal from the plans of President Biden’s SEC Chair Gary Gensler to closely regulate the crypto industry.

The new framework was introduced by Senate Banking Committee Chairman Tim Scott of South Carolina and Senator Cynthia Lummis of Wyoming, who heads the panel’s Digital Assets Committee. Robinhood CEO Vlad Tenev said on CNBC’s “Squawk Box” that the regulatory development was important for the U.S. to regain the lead in the crypto industry, where he said it has fallen behind other markets, including Europe.

Last week, the senate passed a stablecoin bill, marking the first major legislative win for the crypto industry, which now heads to the House for consideration of its version of the bill. Both bills prohibit yield-bearing consumer stablecoins — but differ on agency regulatory oversight. Visa CEO Ryan McInerney weighed in on the advancement of the Senate version, the Genius Act, telling CNBC’s “Squawk on the Street” that the credit card giant has been embracing stablecoins. 

Meanwhile, investors increased their bets on crypto company Digital Asset, which raised $135 million in funding from several big names in banking and finance, including Goldman Sachs, BNP Paribas and hedge fund billionaire Ken Griffin’s Citadel Securities. The firm, which touts itself as a regulated crypto player, said it will use the funding to advance adoption of its Canton network, which is a blockchain for financial institutions, another sign of how major financial institutions are embedding themselves into the once obscure crypto world.

Nvidia CEO Huang sells  million worth of stock, first sale of 3 million plan

Nvidia CEO Jensen Huang sold 100,000 shares of the chipmaker’s stock on Friday and Monday, according to a filing with the U.S. Securities and Exchange Commission.

The sales are worth nearly $15 million at Tuesday’s opening price.

The transactions are the first sale in Huang’s plan to sell as many as 600,000 shares of Nvidia through the end of 2025. It’s a plan that was announced in March, and it’d be worth $873 million at Tuesday’s opening price.

The Nvidia founder still owns more than 800 million Nvidia shares, according to Monday’s SEC filing. Huang has a net worth of about $126 billion, ranking him 12th on the Bloomberg Billionaires Index.

The 62-year-old chief executive sold about $700 million in Nvidia shares last year under a prearranged plan, too.

Nvidia stock is up more than 800% since December 2022 after OpenAI’s ChatGPT was first released to the public. That launch drew attention to Nvidia’s graphics processing units, or GPUs, which were needed to develop and power the artificial intelligence service.

The company’s chips remain in high demand with the majority of the AI chip market, and Nvidia has introduced two subsequent generations of its AI GPU technology.

Nvidia continues to grow. Its stock is up 9% this year, even as the company faces export control issues that could limit foreign markets for its AI chips.

In May, the company reported first-quarter earnings that showed the chipmaker’s revenue growing 69% on an annual basis to $44 billion during the quarter.
