Tesla CEO Elon Musk says China’s new trade restrictions on rare earth magnets have affected the production of the company’s Optimus humanoid robots, which rely on the exports.
Speaking on a Tesla earnings call on Tuesday, Musk said that the company was working through the issue with Beijing and hoped to get approval to access the critical resources.
China, earlier this month, imposed new export controls on seven rare earth elements and magnets used in everything from defense to energy to automotive technologies. The move was in retaliation for U.S. President Donald Trump’s escalating tariffs.
According to Musk, Beijing has asked Tesla to guarantee that the rare earth magnets under expert control will not be used for military purposes.
“China wants some assurances that these aren’t used for military purposes, which obviously they’re not. They’re just going into a humanoid robot,” he said.
The new restrictions, which have raised the risk of global shortages, require exporters of medium and heavy rare earths in question to receive licenses from China’s Ministry of Commerce.
China dominates the market for many of these rare earths, with the U.S. unprepared to fill a potential shortfall, according to the Center for Strategic & International Studies.
Meanwhile, the Trump administration has into potential new tariffs on all U.S. imports of critical minerals in response to China’s export controls.
Future growth at risk?
During the earnings call on Tuesday, Musk emphasized the importance of humanoid robots to the company’s future plans.
“The future of the company is fundamentally based upon large scale autonomous cars and large scale, large volume and vast numbers of autonomous humanoid robots,” he said.
Previously, Musk had announced plans for Optimus to produce about 5,000 units this year as the technology grows as part of Tesla’s future business plans. Moreover, he said that Tesla would deploy the robots in its EV factories.
It’s unclear to what extent export controls might alter these plans. However, Musk reassured investors on Tuesday that the company still plans to produce thousands of robots this year, with thousands also expected to be deployed at Tesla factories.
The emerging technology could help Tesla drive some investor optimism as its EV business struggles, with its stock down about 37% year-to-date.
Steve Westly, founder and managing partner of The Westly Group and former Tesla Board member, told CNBC’s ‘Closing Bell Overtime‘ on Tuesday that the company needs to find a new growth engine soon.
The company is expected to face stiff competition from other humanoid robot players in China, such as Unitree Robotics and AgiBot, both of which reportedly plan to enter mass production this year. The export controls could give the Chinese players another advantage over their U.S. competitors, according to some analysts.
While Musk is upbeat about Tesla’s prospects in the space, going so far as to claim that it is ahead of the competition, he is concerned that the leaderboard will be filled with Chinese companies.

Navan, a developer of corporate travel and expense software, expects its market cap to be as high as $6.5 billion in its IPO, according to an updated regulatory filing on Friday.
The company said it anticipates selling shares at $24 to $26 each. Its valuation in that range would be about $3 billion less than where private investors valued Navan in 2022, when the company announced a $300 million funding round.
CoreWeave, Circle and Figma have led a resurgence in tech IPOs in 2025 after a drought that lasted about three years. Navan filed its original prospectus on Sept. 19, with plans to trade on the Nasdaq under the ticker symbol “NAVN.”
Last week, the U.S. government entered a shutdown that has substantially reduced operations inside of agencies including the SEC. In August, the agency said its electronic filing system, EDGAR, “is operated pursuant to a contract and thus will remain fully functional as long as funding for the contractor remains available through permitted means.”
Cerebras, which makes artificial intelligence chips, withdrew its registration for an IPO days after the shutdown began.
Navan CEO Ariel Cohen and technology chief Ilan Twig started the company under the name TripActions in 2015. It’s based in Palo Alto, California, and had around 3,400 employees at the end of July.
For the July quarter, Navan recorded a $38.6 million net loss on $172 million in revenue, which was up about 29% year over year. Competitors include Expensify, Oracle and SAP. Expensify stock closed at $1.64on Friday, down from its $27 IPO price in 2021.
Navan ranked 39th on CNBC’s 2025 Disruptor 50 list, after also appearing in 2024.

Shares of Amazon, Nvidia and Tesla each dropped around 5% on Friday, as tech’s megacaps lost $770 billion in market cap, following President Donald Trump’s threats for increased tariffs on Chinese goods.
With tech’s trillion-dollar companies occupying an increasingly large slice of the U.S. market, their declines send the Nasdaq down 3.6% and the S&P 500 down 2.7%. For both indexes, it was the worst day since April, when Trump said he would slap “reciprocal” duties on U.S. trading partners.
After market close on Friday, Trump declared in a social media post that the U.S. would impose a 100% tariff on China and on Nov. 1 it would apply export controls “on any and all critical software.”
Amazon, Nvidia and Tesla all slipped about 2% in extended trading following the post.
The president’s latest threats are disrupting, at least briefly, what had been a sustained rally in tech, built on hundreds of billions of dollars in planned spending on artificial intelligence infrastructure.

In late September, Nvidia, which makes graphics processing units for training AI models, became the first company to reach a market cap of $4.5 trillion. Nvidia alone saw its market capitalization decline by nearly $229 billion on Friday.
OpenAI counts on Nvidia’s GPUs from a series of cloud suppliers, including Microsoft. OpenAI is only seeing rising demand.
In September it introduced the Sora 2 video creation app, and this week the company said the ChatGPT assistant now boasts over 800 million weekly users. But Microsoft must buy infrastructure to operate its cloud data centers. Microsoft’s market cap dropped by $85 billion on Friday.
The sell-off wiped out Amazon’s gains for the year. That stock is now down 2% so far in 2025. It competes with Microsoft to rent out GPUs from its cloud data centers, but it doesn’t have major business with OpenAI. The online retailer is now worth $121 billion less than it was on Thursday.
“There continues to be a lot of noise about the impact that tariffs will have on retail prices and consumption,” Amazon CEO Andy Jassy told analysts in July. “Much of it thus far has been wrong and misreported. As we said before, it’s impossible to know what will happen.”
Tesla, which introduced lower-priced vehicles on Tuesday, saw its market capitalization sink by $71 billion.
The automaker reports third-quarter results on Oct. 22, with Microsoft earnings scheduled for the following week. Nvidia reports in November.
Google parent Alphabet and Facebook owner Meta fell 2% and almost 4%, respectively.
Govini, a defense tech software startup taking on the likes of Palantir, has blown past $100 million in annual recurring revenue, the company announced Friday.
“We’re growing faster than 100% in a three-year CAGR, and I expect that next year we’ll continue to do the same,” CEO Tara Murphy Dougherty told CNBC’s Morgan Brennan in an interview. With how “big this market is, we can keep growing for a long, long time, and that’s really exciting.”
CAGR stands for compound annual growth rate, a measurement of the rate of return.
The Arlington, Virginia-based company also announced a $150 million growth investment from Bain Capital. It plans to use the money to expand its team and product offering to satisfy growing security demands.
In recent years, venture capitalists have poured more money into defense tech startups like Govini to satisfy heightened national security concerns and modernize the military as global conflict ensues.
The group, which includes unicorns like Palmer Luckey’s Anduril, Shield AI and artificial intelligence beneficiary Palantir, is taking on legacy giants such as Boeing, Lockheed Martin and Northrop Grumman, that have long leaned on contracts from the Pentagon.

Dougherty, who previously worked at Palantir, said she hopes the company can seize a “vertical slice” of the defense technology space.
The 14-year-old Govini has already secured a string of big wins in recent years, including an over $900-million U.S. government contract and deals with the Department of War.
Govini is known for its flagship AI software Ark, which it says can help modernize the military’s defense tech supply chain by better managing product lifecycles as military needs grow more sophisticated.
“If the United States can get this acquisition system right, it can actually be a decisive advantage for us,” Dougherty said.
Looking ahead, Dougherty told CNBC that she anticipates some setbacks from the government shutdown.
Navy customers could be particularly hard hit, and that could put the U.S. at a major disadvantage.
While the U.S. is maintaining its AI dominance, China is outpacing its shipbuilding capacity and that needs to be taken “very seriously,” she added.
