The U.S. Supreme Court has declined to hear an appeal from former Theranos executive Ramesh “Sunny” Balwani, keeping him in federal prison as he serves a 12-year-and-11-month sentence for defrauding investors and patients. The court’s decision in October 2026 brings a close to Balwani’s legal challenges regarding his 2022 convictions on all 12 counts brought against him.
As president and chief operating officer of the failed blood-testing startup, Balwani oversaw daily operations alongside founder Elizabeth Holmes. Prosecutors proved that the pair misrepresented the capabilities of Theranos technology, claiming it could perform comprehensive tests on tiny finger-prick samples, even though the machines could only reliably handle a limited number of tests. Evidence showed Balwani was aware of the inaccuracies in some results but continued to promote the services anyway.
The convictions cover conspiracies and wire fraud aimed at investors and patients. Balwani pleaded not guilty and argued that important context from a 2013 investor call was kept from the jury, but the Supreme Court rejected his challenge.
The Theranos saga promised to revolutionize medical testing and projected billions in future revenue, though prosecutors showed the actual business prospects were far weaker. Holmes, who founded the company in 2003, received a sentence of 11 years and three months, with her convictions focused on investor fraud. Both former executives have been jointly and individually ordered to pay over $452 million in restitution.
