Taiwan Semiconductor Manufacturing Co. said on Tuesday that it had detected “unauthorized activities” that lead to the discovery of potential trade secret leaks.

The world’s biggest semiconductor manufacturer told CNBC that it has taken “strict” disciplinary action against the personnel involved and that it has also launched legal proceedings.

“TSMC maintains a zero-tolerance policy toward any actions that compromise the protection of trade secrets or harm the company’s interests,” the company said.

“Such violations are dealt with strictly and pursued to the fullest extent of the law. We remain committed to safeguarding our core competitiveness and the shared interests of all our employees.”

Semiconductors have grown in strategic importance in recent years as they have become the key pillar in the boom in artificial intelligence models and applications. Rising geopolitical tensions has put the spotlight on the competitive technological advantages of major firms in the chip supply chain like TSMC and other leaders across the board.

TSMC, headquartered in Taiwan, dominates the market for the manufacturing of the world’s most advanced chips and counts major tech giants including Apple and Nvidia as clients.

As the case is now under judicial review, TSMC is unable to provide further information, the firm said.

TSMC identified the issue early due to its “comprehensive and robust monitoring mechanisms,” the company said, adding that it carried out swift internal investigations.

Nikkei Asia, citing multiple sources familiar with the matter, reported on Tuesday that several former employees of TSMC are suspected of attempting to obtain critical proprietary information on 2-nanometer chip development and production while they were still working at the company.

Production of the 2-nanometer chip is among the leading edge manufacturing processes in the semiconductor industry currently. TSMC said it did not have any additional information to share when asked by CNBC about the Nikkei report.

As the world’s leading chipmaker, TSMC has a treasure trove of intellectual property. By its own account, the company has previously said it has more than 200,000 trade secrets recorded in its internal system.

It is not the first time that TSMC has been the target for potential theft. In 2018, a Taiwanese court indicted a former employee for copying trade secretes related to the 28-nanometer fabrication process, with intent to transfer them to a semiconductor company in mainland China.

In 2023, ASML, which makes machines that are required to manufacture the most advanced chips, said that it discovered that a former employee in China had misappropriated data related to its proprietary technology.

U.S. charges two Chinese nationals for illegally shipping Nvidia AI chips to China

U.S. charges two Chinese nationals for illegally shipping Nvidia AI chips to China

China is one of Nvidia’s largest markets, particularly for data centers, gaming and artificial intelligence applications.

Two Chinese nationals in California have been arrested and charged with the illegal shipment of tens of millions of dollars worth of AI chips, including from Nvidia, the Department of Justice said Tuesday. 

Chuan Geng, 28, and Shiwei Yang, 28, exported the sensitive chips and other technology to China from October 2022 through July 2025 without obtaining the required licenses, the DOJ said.

The illicit shipments included Nvidia’s H100 general processing units, according to a criminal complaint provided to CNBC. The H100 is amongst the U.S. chipmaker’s most cutting-edge chips used in artificial intelligence applications. 

The Department of Commerce has placed such chips under export controls since 2022 as part of broader efforts by the U.S. to restrict China’s access to the most advanced semiconductor technology. 

This case demonstrates that smuggling is a “nonstarter,” Nvidia told CNBC. “We primarily sell our products to well-known partners, including OEMs, who help us ensure that all sales comply with U.S. export control rules.”

“Even relatively small exporters and shipments are subject to thorough review and scrutiny, and any diverted products would have no service, support, or updates,” the chipmaker added.

Geng and Yang’s California-based company, ALX Solutions, had been founded shortly after the U.S. chip controls first came into place. 

According to the DOJ, law enforcement searched ALX Solutions’ office and seized phones belonging to Geng and Yang, which revealed incriminating communications between the defendants, including those about evading U.S. export laws by shipping sensitive chips to China through Malaysia.

The review also showed that in December 2024, ALX Solutions made over 20 shipments from the U.S. to shipping and freight-forwarding companies in Singapore and Malaysia, which the DOJ said are commonly used as transshipment points to conceal illicit shipments to China.

ALX Solutions did not appear to have been paid by entities they purportedly exported goods to, instead receiving numerous payments from companies based in Hong Kong and China.

The U.S. Department of Commerce’s Bureau of Industry and Security and the FBI are continuing to investigate the matter.

The smuggling of advanced microchips has become a growing concern in Washington. According to a report from the Financial Times last month, at least $1 billion worth of Nvidia’s chips entered China after Donald Trump tightened chip export controls earlier this year. 

In response to the report, Nvidia had said that data centers built with smuggled chips were a “losing proposition” and that it does not support unauthorized products.

Opendoor tanks after earnings as CEO thanks new investors for ‘increased visibility’

Opendoor tanks after earnings as CEO thanks new investors for 'increased visibility'

With Opendoor shares up almost fivefold since the beginning of July and trading volumes hitting record levels, CEO Carrie Wheeler thanked investors for their “enthusiasm” on Tuesday’s earnings call.

“I want to acknowledge the great deal of interest in Opendoor lately and that we’re grateful for it,” Wheeler said, even as the stock sank more than 20% after hours. “We appreciate your enthusiasm for what we’re building, and we’re listening intently to your feedback.”

Prior to its recent surge, Opendoor’s stock had been mostly abandoned, falling as low as 51 cents in late June. The situation was so dire that the company was considering a reverse split that could lift the price of each share by as much 50 times as a potential way to keep its Nasdaq listing. Opendoor said last week that it’s back in compliance and canceled the reverse split proposal.

Opendoor’s business is centered around using technology to buy and sell homes, pocketing the gains. The company was founded in 2014 and went public through a special purpose acquisition company (SPAC) during the Covid-era boom of late 2020. But when interest rates began climbing in 2022, higher borrowing costs reduced demand for homes.

Revenue sank by about two-thirds from $15.6 billion in 2022 to $5.2 billion last year.

Much of the stock’s bounce in the past six weeks was spurred by hedge fund manager Eric Jackson, who announced in July that his firm had taken a position in Opendoor. Jackson said he believes Opendoor’s stock could eventually get to $82. It closed on Tuesday at $2.52, before dropping below $2 in extended trading.

Jackson’s bet is that a return to revenue growth and increased market share will lead to profitability, and that investors will start ascribing a reasonable sales multiple to the business.

The turnaround isn’t yet showing much evidence of working. For the second quarter, Opendoor reported a revenue increase of about 4% to $1.57 billion. Its net loss narrowed to $29 million, or 4 cents a share, from $92 million, or 13 cents, a year earlier.

In the current quarter, Opendoor is projecting just $800 million to $875 million in revenue, which would represent a decline of at least 36% from a year earlier. Opendoor said it expects to acquire just 1,200 homes in the the third quarter, down from 1,757 in the second quarter and 3,504 in the third quarter of 2024. It’s also pulling down marketing spending.

“The housing market has further deteriorated over the course of the last quarter,” finance chief Selim Freiha said on Tuesday’s earnings call. “Persistently high mortgage rates continue to suppress buyer demand, leading to lower clearance and record new listings.”

Wheeler highlighted Opendoor’s effort to expand its business beyond so-called iBuying and into more of a referrals business that’s less capital intensive. She called it “the most important strategic shift in our history.”

Investors, who have been bidding up the stock in waves, were less than enthused with what they heard. But at least there are finally people listening.

“This increased visibility is an opportunity to tell our story to a broader audience,” Wheeler said. “We intend to make the most of it.”

Super Micro Computer shares slid 15% in extended trading on Tuesday after the server maker reported disappointing fiscal fourth-quarter results and issued weak quarterly earnings guidance.

Here’s how the company did in comparison with LSEG consensus:

  • Earnings per share: 41 cents adjusted vs. 44 cents expected
  • Revenue: $5.76 billion vs. $5.89 billion expected

Super Micro’s revenue increased 7.5% during the quarter, which ended on June 30, according to a statement.

For the current quarter, Super Micro called for 40 cents to 52 cents in adjusted earnings per share on $6 billion to $7 billion in revenue for the fiscal first quarter. Analysts surveyed by LSEG were looking for 59 cents per share and $6.6 billion in revenue.

For the 2026 fiscal year, Super Micro sees at least $33 billion in revenue, above the LSEG consensus of $29.94 billion.

Super Micro saw surging demand starting in 2023 for its data center servers packed with Nvidia for handling artificial intelligence models and workloads. Growth has since slowed.

The company avoided being delisted from the Nasdaq after falling behind on quarterly financial filings and seeing the departure of its auditor.

As of Tuesday’s close, Super Micro shares were up around 88% so far in 2025, while the S&P 500 index has gained 7%.

Executives will discuss the results on a conference call starting at 5 p.m. ET.
