The company’s downfall began in October 2015 after The Wall Street Journal reported that Theranos’ technology did not work as advertised. Federal prosecutors later alleged that Holmes’ deception put patients at risk, citing inaccurate Theranos test results provided to people being screened for cancer and pregnant women. Holmes was indicted on June 14, 2018.
During a nearly four-month federal trial that began in September 2021, prosecutors argued that Holmes knew Theranos’ technology had significant limitations and could not consistently deliver reliable results. Evidence showed the company frequently relied on standard lab equipment even as Holmes “led investors and the public to believe that Theranos was conducting most or all of its tests using its own analyzer,” according to a press release from the U.S. Attorney’s Office for the Northern District of California. Prosecutors also said Holmes misled investors about the extent of outside support for Theranos, overstated the company’s projected revenue and gave a false impression of its ties to organizations including the U.S. Defense Department and Walgreens.
Jurors ultimately found Holmes guilty of conspiring to defraud investors and three counts of wire fraud tied to investors that amounted to more than $140 million. She was sentenced to 135 months in prison and later, along with former Theranos executive Ramesh “Sunny” Balwani, ordered to pay more than $452 million in restitution. According to NPR, Holmes’ case was unprecedented among major technology startups, making her the sector’s first CEO to be convicted and imprisoned for criminal wrongdoing.
In March 2026, Holmes’ prison term was shortened to 10 years and 3 months after a federal judge found she had not personally caused “substantial financial hardship” to victims. The former Theranos CEO is serving her sentence at a minimum-security federal prison camp in Bryan, Texas. She is expected to be transferred to the Austin Transitional Center, a halfway house near Austin, in August 2027.
