Theranos whistleblower Tyler Shultz warned on October 30, 2026 that the AI boom is a great opportunity to deceive people. TechCrunch reported that he said the cautionary Theranos story takes on new significance as companies that have never turned a profit raise capital at trillion-dollar valuations. The warning comes as AI firms attract heavy investment despite unproven business models. Shultz's account draws on his role in exposing the fraud at Theranos, the blood-testing company whose claims collapsed under scrutiny.
