Shares of Intel slumped Thursday after President Donald Trump said in a social media post that the chipmaker’s CEO needs to resign.

“The CEO of Intel is highly CONFLICTED and must resign, immediately,” Trump posted on Truth Social. “There is no other solution to this problem. Thank you for your attention to this problem!”

Trump made the post after Sen. Tom Cotton sent a letter to Intel Chairman Frank Yeary expressing concern over CEO Lip-Bu Tan’s investments and ties to semiconductor firms that are reportedly linked to the Chinese Communist Party and the People’s Liberation Army, and asked the board whether Tan had divested his interests in these companies to eliminate any conflicts of interest.

Intel did not immediately respond to a request for comment, so it is not immediately clear if Tan has divested his interests in the companies.

“In March 2025, Intel appointed Lip-Bu Tan as its new CEO,” Cotton wrote in the letter. “Mr. Tan reportedly controls dozens of Chinese companies and has a stake in hundreds of Chinese advanced-manufacturing and chip firms. At least eight of these companies reportedly have ties to the Chinese People’s Liberation Army.”

Tan, who took over as CEO in March, previously launched the venture capital firm Walden International in 1987 to focus on funding tech start-ups, including chip makers. China’s state media has described Tan as “actively” devoted to Chinese and Asian markets, having invested not only in the Taiwan Semiconductor Manufacturing Company but also China’s state-owned enterprise SMIC, which seeks to advance China’s chipmaking capabilities.

The demands made by Trump and Cotton come as economic and political rivalries between the U.S. and China increasingly focus on the competition over chips, AI and other digital technologies that experts say will shape future economies and military conflicts.

Cotton, the chairman of the Senate Intelligence Committee, has raised concerns that Chinese spies could be working at tech companies and defense contractors, using their positions to steal secrets or plant digital backdoors that give China access to classified systems and networks.

On Thursday the Arkansas Republican wrote to the Department of Defense urging Defense Secrectary Pete Hegseth to ban all non-U.S. citizens from jobs allowing them to access DoD networks. He has also demanded an investigation into Chinese citizens working for defense contractors.

“The U.S. government recognizes that China’s cyber capabilities pose one of the most aggressive and dangerous threats to the United States, as evidenced by infiltration of our critical infrastructure, telecommunications networks, and supply chains,” Cotton wrote in an earlier letter calling on the Pentagon to conduct the investigation.

National security officials have linked China’s government to hacking campaigns targeting prominent Americans and critical U.S. systems.

“U.S. companies who receive government grants should be responsible stewards of taxpayer dollars and adhere to strict security regulations,” Cotton wrote on the social platform X.

Intel had been a beneficiary of the Biden administration’s CHIPS Act, receiving more than $8 billion in federal funding to build computer chip plants around the country.

Shares of the California company slid 3.5%, while markets, particularly the tech-heavy Nasdaq, gained ground.

Founded in 1968 at the start of the PC revolution, Intel missed the technological shift to mobile computing triggered by Apple’s 2007 release of the iPhone, and it’s lagged more nimble chipmakers. Intel’s troubles have been magnified since the advent of artificial intelligence — a booming field where the chips made by once-smaller rival Nvidia have become tech’s hottest commodity.

Intel is shedding thousands of workers and cutting expenses — including some domestic semiconductor manufacturing capabilities — as Tan tries to revive the fortunes of the struggling chipmaker.

Tesla is awarding CEO Elon Musk 96 million shares of restricted stock valued at approximately $29 billion, just six months after a judge ordered the company to revoke his massive pay package.

The electric vehicle maker said in a regulatory filing on Monday that Musk must first pay Tesla $23.34 per share of restricted stock that vests, which is equal to the exercise price per share of the 2018 pay package that was awarded to the company’s CEO.

In December Delaware Chancellor Kathaleen St. Jude McCormick reaffirmed her earlier ruling that Tesla must revoke Musk’s multibillion-dollar pay package. She found that Musk engineered the landmark pay package in sham negotiations with directors who were not independent.

At the time McCormick also rejected an equally unprecedented and massive fee request by plaintiff attorneys, who argued that they were entitled to legal fees in the form of Tesla stock valued at more than $5 billion. The judge said the attorneys were entitled to a fee award of $345 million.

The rulings came in a lawsuit filed by a Tesla stockholder who challenged Musk’s 2018 compensation package.

That pay package carried a potential maximum value of about $56 billion, but that sum has fluctuated over the years based on Tesla’s stock price.

Musk appealed the order in March. A month later Tesla said in a regulatory filing that it was creating a special committee to look at Musk’s compensation as CEO.

Tesla shares have plunged 25% this year, largely due to blowback over Musk’s affiliation with President Donald Trump. But Tesla also faces intensifying competition from both the big Detroit automakers, and from China.

In its most recent quarter, Tesla reported that quarterly profits plunged from $1.39 billion to $409 million. Revenue also fell and the company fell short of even the lowered expectations on Wall Street.

Under pressure from shareholders last month, Tesla scheduled an annual shareholders meeting for November to comply with Texas state law.

A group of more than 20 Tesla shareholders, which have watched Tesla shares plummet, said in a letter to the company that it needed to at least provide public notice of the annual meeting.

Investors have grown increasingly worried about the trajection of the company after Musk had spent so much time in Washington this year, becoming one of the most prominent officials in the Trump administration in its bid to slash the size of the U.S. government.
