Fallen Silicon Valley star Elizabeth Holmes takes the stand in her criminal fraud trial
Fallen Silicon Valley star Elizabeth Holmes, accused of bamboozling investors and patients about her startup Theranos and its medical device that she said would reshape health care, took the witness stand late Friday in her trial for criminal fraud.
The surprise decision to have Holmes testify so early in her defense came as a bombshell and carries considerable risk. Federal prosecutors, who rested their months-long case earlier on Friday, have made it clear that they’re eager to grill Holmes under oath.
Prosecutors aren’t likely to get that chance until after the Thanksgiving holiday weekend. Holmes attorney Kevin Downey told U.S. District Judge Edward Davila that he expects to continue steering her through her story when she returns to the stand Monday and again Tuesday in a San Jose, California, courtroom before the trial breaks until Nov. 29.
Prosecutors called 29 witnesses to support their contention that Holmes endangered patients’ lives while also duping investors and customers about Theranos’ technology. Among them was Gen. James Mattis, a former U.S. defense secretary and former Theranos board member, who explained how he was first impressed and ultimately disillusioned by Holmes.
They also presented internal documents and sometimes salacious texts between Holmes and her former lover, Sunny Bulwani, who also served as Theranos’ chief operating officer. In court documents, Holmes’ attorneys have asserted she was manipulated by Balwani through “intimate partner abuse” — an issue that is expected to come up during her ongoing testimony next week.
Until she took the stand Friday, Holmes had sat bolt upright in her chair to the far right of the jury through the trial, impassive even when one-time supporters testified to their misgivings about Theranos.
That combination of compelling testimony and documentary evidence apparently proved effective at convincing Holmes to tell her side of the story to the jury of 10 men and four women (including two alternates) who will ultimately decide her fate. If convicted, Holmes — now 37 and mother to a recently born son — could be sentenced to up to 20 years in prison.
Shortly after 3 p.m., Holmes walked slowly to the stand before a rapt courtroom filled with spectators and jurors, all wearing masks.
Maskless behind a transparent barrier, Holmes recounted her early years as a student at Stanford University and her interest in disease detection. That culminated in her decision to drop out of school in 2003 at the age of 19 to found the startup that eventually became Theranos. Holmes said the name was derived from the words “therapy” and “diagnosis”.
Holmes said she convinced her parents to let her use her college savings to finance her ambitions to shake up the health care industry. “I started working all the time … trying to meet people who could help me could build this,” Holmes said in a husky voice that became one of her trademarks during Theranos’ rise.

Apple to spend $30 billion on Broadcom chips as it boosts US sourcing
Apple , opens new tab plans to spend more than $30 billion under a multi-year chip supply deal with Broadcom, bolstering its U.S. sourcing as President Donald Trump’s administration pushes to expand domestic chip manufacturing.
Broadcom shares rose more than 4%, while Apple shares were down marginally.
Apple said on Wednesday the deal, which was struck earlier this week and runs through 2031, covers FBAR filters – or radio-frequency chips used for wireless connectivity in its devices – that it had been developing with Broadcom since at least 2023.
Broadcom will invest $1.5 billion to expand its Fort Collins, Colorado, factory under the deal, which Apple said would result in the production of at least 15 billion chips and support its work with the Trump administration to source more components domestically.
“The cutting-edge components built in Fort Collins are essential to delivering the incredible performance and connectivity our customers expect, and we’re proud to deepen our investments in U.S.-based suppliers that share our commitment to excellence and innovation,” Apple CEO Tim Cook said in a statement.
“We’re grateful to the president and his administration for supporting important projects like this.”
In August 2025, Apple raised its U.S. investment commitment to $600 billion over four years, adding $100 billion to a previously announced spending plan.

China plans to let top AI firms buy limited Nvidia H200 chips, the Information reports
China is planning to allow the country’s top AI companies to buy a limited number of Nvidia’s, opens new tab H200 chips, the Information reported on Wednesday, citing two people with direct knowledge of the matter.
Chinese officials have told Alibaba, opens new tab, ByteDance and DeepSeek in recent weeks that they may soon receive permission to buy some H200 chips, the report said.
Shares of Nvidia rose 1% after the report.
The chip giant did not immediately respond to a Reuters request for comment, nor did the U.S. commerce department, which oversees exports of advanced AI chips overseas.
China’s commerce ministry also did not immediately respond to a request for comment, while Alibaba, ByteDance and DeepSeek did not respond outside of regular business hours.
The U.S. government has allowed Nvidia to sell its advanced H200 chips to China, and licensed about 10 Chinese firms to buy the chips. However, Chinese officials, keen to nurture domestic suppliers, have withheld approval so far.
Reuters reported in March that Nvidia had won Beijing’s approval to sell the chips to China, citing sources, and around the same time, Nvidia CEO Jensen Huang also told CNBC that the company had clearance from China.
Beijing is still determining the exact number of Nvidia chips to approve, and it could amount to fewer than 200,000 in total, the Information said, adding that was less than half of what the companies requested earlier this year.
Last month, Reuters exclusively reported that Nvidia told Chinese clients its new “Vera” central processors for AI data centres could be available as soon as August and that they can begin placing orders.
Nvidia’s market share in China has effectively fallen to zero, Huang said in October, hurt by U.S. export controls and Beijing’s push for self-reliance in key technologies.
The potential shift in China’s stance underscores the growing computing capacity crunch that the country’s tech companies are facing.

Australia’s under-16 social media ban fails first age check hurdle, study finds
A team of software testers found that Australian social media platforms did not request age proof for any of 50 accounts that declared themselves to be 16, a result that leaves the country’s world-first under-16 ban “ineffective” at the most basic screening stage, according to a study seen by Reuters.
Since December, platforms such as Instagram, Snapchat and YouTube have been required to bar people under 16 and take “reasonable steps” to verify age, with regulators recommending multiple layered checks. But the new research, conducted by those who advised the nationwide curb, shows that the initial vetting step, which estimates a user’s age from general online activity, is failing to flag young people for tougher verification.
The testers, who last year trialled age-assurance software on more than 1,000 Australians, opened 50 new accounts after the law took effect and set the age as 16. None of the platforms asked for additional proof, the researchers told Reuters. The findings highlight a flaw that has been largely overlooked while public debate has focused on photo-based age-estimation tools.
The ban’s rollout has been widely criticised after surveys indicated that most under-16s still access the platforms. The government last month doubled the maximum fine and warned of possible court action against tech giants, accusing them of setting the system up to fail. Platforms have countered that they are simply following the regulator’s guidance, which prioritises low-friction checks and prevents reliance on government ID alone due to privacy concerns.
Some advisers to the original trial said they had repeatedly warned that the testing process ignored real-world circumvention, including minors entering false birthdates. “We did want to talk about circumvention, but we kept on being told that that wasn’t part of the actual trial,” Colm Gannon of the International Centre for Missing & Exploited Children told Reuters. A youth digital rights academic involved in a longer-term study of the ban said more impressive results might emerge once platforms move to age-inference methods later in the year. The regulator maintains that the recommended layered approach, if implemented correctly, ensures no single point of failure.
