Elizabeth Holmes: Age, Husband, Children, Net Worth, Theranos, Prison Sentence and Life Story
Elizabeth Holmes is an American former entrepreneur best known as the founder of Theranos, the blood-testing startup that was once valued at $9 billion before collapsing amid fraud investigations. Here is a look at her age, education, career, husband, children, net worth, criminal conviction and current status.
Elizabeth Anne Holmes was born on February 3, 1984, in Washington, D.C. She founded Theranos in 2003 after dropping out of Stanford University and presented the company as a revolutionary healthcare technology business that could perform a wide range of blood tests using only tiny amounts of blood.
Her rise made her one of the most prominent young entrepreneurs in Silicon Valley. At the height of Theranos, Holmes was described as the world’s youngest self-made female billionaire, with Forbes valuing her wealth at billions of dollars based on the company’s valuation.
That image collapsed after investigations found serious problems with Theranos’s technology and claims. Holmes was eventually convicted of defrauding investors and sentenced to federal prison.

Who Is Elizabeth Holmes?
Elizabeth Holmes is a former American businesswoman who founded Theranos, a health-technology company that promised to transform medical blood testing.
The company’s central pitch was that conventional blood testing could be replaced or supplemented by technology capable of conducting many tests from a very small blood sample, potentially collected through a finger prick.
Holmes founded the company when she was just 19 years old. Theranos attracted major investors and influential board members, and its valuation eventually reached $9 billion.
The company later became one of the most prominent corporate-fraud scandals in Silicon Valley.
Elizabeth Holmes’ Early Life and Family Background
Holmes was born in Washington, D.C., to Christian Rasmus Holmes IV and Noel Anne Daoust.
Her father worked as a vice president at Enron subsidiary Clean Energy Solutions Group and later held executive positions at government agencies including USAID, the Environmental Protection Agency and the U.S. Trade and Development Agency.
Her mother worked as a Congressional committee staffer.
Holmes also has Danish ancestry. One of her paternal great-great-great-grandfathers was Charles Louis Fleischmann, a Jewish-Hungarian immigrant who founded Fleischmann’s Yeast.
According to accounts of her family background, the Holmes family took considerable pride in its connection to the Fleischmann yeast business and its earlier wealth.

Where Did Elizabeth Holmes Go to College?
Holmes attended St. John’s School in Houston, where she developed an interest in computer programming.
She has said that while in high school she started a business selling C++ compilers to Chinese universities.
Her parents arranged Mandarin Chinese tutoring for her, and she also attended Stanford University’s summer Mandarin program.
In 2002, Holmes enrolled at Stanford University, where she studied chemical engineering. She worked as a student researcher and laboratory assistant at Stanford’s School of Engineering and was a member of Kappa Alpha Theta.
After her freshman year, she worked at the Genome Institute of Singapore, where she participated in research involving blood samples and SARS-CoV-1.
She filed her first patent application in 2003 for a wearable drug-delivery patch.
In March 2004, Holmes left Stanford’s School of Engineering and used her tuition money as seed funding for her own healthcare technology company.
How Did Elizabeth Holmes Start Theranos?
Holmes founded a company called Real-Time Cures in Palo Alto, California, in 2003.
Her stated goal was to make healthcare more accessible. She also described her fear of needles as one motivation for developing a system that could use very small quantities of blood.
Holmes pitched the concept of extracting large amounts of medical information from only a few drops of blood.
However, several medical experts, including Stanford professor Phyllis Gardner, told Holmes they did not believe the technology could work as she described it.
Holmes continued pursuing the idea with the support of Stanford engineering professor Channing Robertson, who became the company’s first board member and helped introduce her to venture capitalists.
The company was renamed Theranos, a combination of the words “therapy” and “diagnosis.”
How Much Money Did Elizabeth Holmes Raise?
Holmes raised about $6 million by December 2004.
By the end of 2010, Theranos had raised more than $92 million in venture capital.
The company’s fundraising accelerated as prominent investors and influential figures became associated with it.
By 2014, Theranos had raised more than $400 million, while the company was valued at approximately $9 billion.
Holmes owned a substantial portion of the company and became one of the most celebrated young entrepreneurs in the United States.
Elizabeth Holmes’ Rise to Billionaire Status
In 2014, Forbes ranked Holmes No. 110 on the Forbes 400 list and recognized her as the world’s youngest self-made female billionaire.
In 2015, Forbes reported her net worth at approximately $4.5 billion and described her as the youngest and wealthiest self-made female billionaire in the United States.
The valuation was based largely on the value of her Theranos holdings rather than cash wealth.
At its peak, Theranos employed more than 800 people.
Holmes also appeared on the covers of major publications including Fortune, Forbes, T: The New York Times Style Magazine and Inc.
But within a few years, that billionaire valuation had effectively disappeared.
What Happened to Theranos?
Theranos operated largely in secrecy for years.
In 2013, the company publicly announced a partnership with Walgreens to establish blood-sample collection centers inside its stores.
Holmes subsequently became a major media figure and received widespread praise for supposedly reinventing laboratory medicine.
In 2015, however, investigative reporting began exposing serious questions about whether Theranos’s technology worked as advertised.
A Wall Street Journal investigation by journalist John Carreyrou found that the company’s Edison testing device produced inaccurate results and that Theranos was using commercially available machines from other manufacturers for much of its testing.
Holmes denied the allegations and defended the company.
The revelations triggered regulatory investigations and accelerated Theranos’s collapse.
Why Did Elizabeth Holmes’ Net Worth Fall to Zero?
Holmes’s reported billions were tied primarily to her ownership of Theranos.
When the company’s valuation collapsed, so did the value of her shares.
In 2016, Forbes revised its estimate of Holmes’s net worth to zero after previously valuing her at billions of dollars.
Theranos’s preferred shareholders had priority over Holmes’s common shares, meaning that even an $800 million valuation of the company left her stake essentially worthless.
Holmes was also reported to owe Theranos approximately $25 million connected to the exercise of stock options.
She did not receive company cash from that arrangement and did not sell the shares associated with the debt.
There is no reliable public figure for Holmes’s current personal net worth. Her once-reported $4.5 billion fortune should not be treated as her present wealth.
Elizabeth Holmes and the SEC Case
In March 2018, the U.S. Securities and Exchange Commission charged Holmes, Theranos and former Theranos executive Ramesh “Sunny” Balwani with fraud.
The SEC alleged that the company raised more than $700 million from investors while making false or exaggerated claims about its blood-testing technology.
Among the allegations was a claim that Theranos technology was being used by the U.S. Department of Defense in combat situations.
The company also claimed it had generated approximately $100 million in revenue in 2014, while the company actually generated only about $100,000 that year.
Holmes settled the SEC case.
Under the settlement, she:
- Paid a $500,000 fine
- Returned 18.9 million shares to Theranos
- Gave up voting control of the company
- Accepted a 10-year ban from serving as an officer or director of a public company
What Happened to Elizabeth Holmes in Court?
In June 2018, a federal grand jury indicted Holmes and Balwani on multiple counts of wire fraud and conspiracy to commit wire fraud.
Both pleaded not guilty.
Prosecutors alleged that they participated in two schemes: one involving investors and another involving doctors and patients.
Holmes resigned as Theranos CEO after the indictment but initially remained chairwoman of the board.
Her criminal trial began on August 31, 2021, after delays related to the COVID-19 pandemic and Holmes’s pregnancy.
Holmes testified in her own defense for seven days.
The prosecution presented evidence involving alleged fake demonstrations, falsified validation reports, misleading claims about contracts and overstated Theranos financial information.
Was Elizabeth Holmes Found Guilty?
Yes.
On January 3, 2022, a jury found Holmes guilty on four counts connected to defrauding investors:
- Three counts of wire fraud
- One count of conspiracy to commit wire fraud
She was acquitted on the charges relating to defrauding patients.
The jury did not reach verdicts on three additional investor-related wire-fraud counts. A mistrial was declared on those counts, and prosecutors later agreed to dismiss them.
Elizabeth Holmes’ Prison Sentence
In November 2022, U.S. District Judge Edward Davila sentenced Holmes to 11¼ years in federal prison.
She and Balwani were also ordered to pay $452 million in restitution to victims of the fraud.
Holmes reported to Federal Prison Camp, Bryan, Texas, on May 30, 2023.
The Federal Bureau of Prisons had previously projected a release date in 2032, taking good-conduct credit into account.
In March 2026, Judge Davila reduced Holmes’s sentence by 12 months after considering revised federal sentencing guidelines.
Her appeal had already been rejected by the U.S. Court of Appeals for the Ninth Circuit in February 2025, which upheld her conviction and sentence.
Is Elizabeth Holmes Still in Prison?
As of 2026, Holmes remains associated with her federal prison sentence at Federal Prison Camp, Bryan, Texas.
Her original sentence was reduced by one year in March 2026. The reduction does not erase her conviction or the restitution order.
Elizabeth Holmes’ Husband: Who Is William “Billy” Evans?
After her relationship with Balwani ended, Holmes began dating William “Billy” Evans.
The couple first met in early 2017.
Evans is an heir to Evans Hotels, a family-owned hotel group based in the San Diego area.
Holmes and Evans became engaged in early 2019 and reportedly married in a private ceremony later that year.
How Many Children Does Elizabeth Holmes Have?
Elizabeth Holmes and William “Billy” Evans have two children.
Their children were born in:
- 2021
- 2023
Holmes was pregnant with her first child during the period surrounding her criminal trial.
Elizabeth Holmes and Sunny Balwani
One of the most important relationships in the Theranos story was Holmes’s long-term relationship with Ramesh “Sunny” Balwani, the company’s former president and chief operating officer.
Holmes met Balwani in 2002 during a trip to Beijing connected with Stanford’s Mandarin program.
Holmes was 18 at the time, while Balwani was 19 years older.
Balwani divorced his wife in 2002 and became romantically involved with Holmes in 2003.
The couple later lived together, and although Balwani did not officially join Theranos until 2009, Holmes’s accounts and reporting described him as advising the company from its early years.
Balwani left Theranos in 2016 as investigations intensified.
Holmes said she fired him, while Balwani said he left voluntarily.
Balwani was later separately convicted in connection with the Theranos fraud.
Holmes’ Claims About Her Relationship With Balwani
During her 2021 trial testimony, Holmes said she had been raped while a Stanford student and sought support from Balwani afterward.
She also testified that Balwani was controlling and that he emotionally and sexually abused her during their relationship.
Holmes nevertheless testified that Balwani did not force her to make the false statements to investors, business partners, journalists or company directors that prosecutors described during the case.
Balwani categorically denied Holmes’s abuse allegations in court filings, calling them false and inflammatory.
Elizabeth Holmes’ Role in Theranos’ Collapse
Holmes’s responsibility for Theranos became a central issue in both the company’s collapse and her criminal trial.
Before the company’s failure, she had recruited an unusually powerful network of investors and board members.
The board eventually included prominent figures such as:
- Henry Kissinger, former secretary of state
- William Perry, former secretary of defense
- James Mattis, future secretary of defense
- Gary Roughead, retired U.S. Navy admiral
- Bill Frist, former U.S. senator
- Sam Nunn, former U.S. senator
- Dick Kovacevich, former Wells Fargo CEO
- Riley Bechtel, former Bechtel CEO
Her investors included Rupert Murdoch, the Walton family, the DeVos family, the Cox family and Carlos Slim Helú.
Many of those investors lost tens or hundreds of millions of dollars after Theranos collapsed.
How Did Theranos Finally Shut Down?
Theranos’s workforce shrank rapidly after the investigations.
The company had more than 800 employees at its peak in 2015.
It dismissed:
- 340 employees in October 2016
- 155 more in January 2017
In April 2018, Theranos filed a WARN Act notice announcing plans to permanently lay off another 105 employees, leaving fewer than two dozen workers.
Most remaining employees were laid off in August 2018.
On September 5, 2018, Theranos announced that it had begun the process of formally dissolving, with its remaining cash and assets going to creditors.
Elizabeth Holmes’ Earlier Recognition and Awards
Before the Theranos scandal, Holmes received extensive recognition.
Among her honors and positions were:
- Time magazine’s 100 Most Influential People
- Forbes Under 30 Doers Award
- Forbes’ ranking of the world’s most powerful women
- Glamour Woman of the Year
- Honorary Doctor of Humane Letters from Pepperdine University
- 2015 Horatio Alger Award, making her its youngest recipient
- Fortune Businessperson of the Year
- Fortune 40 Under 40
- Bloomberg’s 50 Most Influential
- Appointment as a member of the Harvard Medical School Board of Fellows
- Appointment by President Barack Obama as a Presidential Ambassador for Global Entrepreneurship
In 2016, Fortune subsequently included Holmes in its list of “The World’s 19 Most Disappointing Leaders.”
Elizabeth Holmes and the Black Turtleneck
Holmes became famous for her distinctive black turtleneck clothing, a style often compared with that of Apple co-founder Steve Jobs.
Holmes has said she wore black turtlenecks from a young age and also said she began wearing them when she founded Theranos.
An employee claimed she was encouraged to copy Jobs’s famous Issey Miyake turtleneck style in 2007.
Her appearance became closely associated with the public image of Theranos and its founder.
Did Elizabeth Holmes Change Her Voice?
Holmes was also known for speaking publicly in a notably deep voice.
Questions later emerged about whether that was her natural voice.
Some former colleagues and Stanford professor Phyllis Gardner questioned whether her voice was naturally that deep, while members of Holmes’s family defended it as authentic.
In a 2023 New York Times interview, Holmes spoke in a higher natural pitch and acknowledged that the low voice had been an affectation.
Elizabeth Holmes’ Work Outside Theranos
Holmes also pursued several promotional and policy initiatives while running Theranos.
In June 2015, she partnered with Mexican businessman Carlos Slim on efforts to improve blood testing in Mexico.
In October 2015, she announced #IronSisters, an initiative intended to support women pursuing careers in science, technology, engineering and mathematics.
She also helped support an Arizona law allowing people to obtain and pay for laboratory tests without insurance or healthcare-provider approval. The law became controversial because of allegations that Holmes had misrepresented the accuracy and effectiveness of Theranos’s technology.
What Is Elizabeth Holmes Doing Now?
Holmes no longer runs Theranos. The company formally dissolved in 2018, and she is serving a federal prison sentence stemming from her conviction for defrauding investors.
Her conviction and sentence were upheld by the Ninth Circuit in 2025, while her sentence was reduced by 12 months in March 2026.
In December 2025, the Los Angeles Times reported that Holmes had begun campaigning for a presidential pardon from President Donald Trump.
Her current public status therefore centers largely on her imprisonment, sentence reduction and continuing legal and political efforts rather than business activity.
Elizabeth Holmes Net Worth: Then vs. Now
Elizabeth Holmes’ financial story is one of the most dramatic parts of the Theranos saga.
| Period | Reported/Estimated Position |
|---|---|
| 2014–2015 | Theranos valued at about $9 billion |
| 2015 | Forbes estimated Holmes’ net worth at about $4.5 billion |
| 2016 | Forbes revised her net worth estimate to zero |
| After Theranos collapse | Her Theranos shares became essentially worthless |
| Current | No reliable public estimate of her net worth |
The key point is that Holmes did not actually possess $4.5 billion in cash. The figure represented the estimated value of her Theranos stake at the company’s peak valuation.
Once Theranos collapsed, that paper wealth disappeared.
The Bottom Line on Elizabeth Holmes
Elizabeth Holmes went from a Stanford dropout who founded a healthcare startup at 19 to one of Silicon Valley’s most celebrated entrepreneurs, with Theranos reaching a reported $9 billion valuation.
Her reputation changed dramatically after investigations challenged the company’s claims about its blood-testing technology. Theranos collapsed, investors lost huge sums, and Holmes was ultimately convicted of defrauding investors.
Today, the Theranos founder’s story is defined less by her former billionaire status than by her criminal conviction, federal prison sentence, restitution order and the collapse of the company that made her famous.
