🩸 Theranos — A $9 Billion Valuation Built on a Machine That Didn't Work

Theranos told investors and the public that its small blood analyzer could perform a broad menu of tests from a fingerstick. Trial evidence showed the device could perform only a few basic tests reliably and that the company relied heavily on conventional machines. Patients faced unreliable results—but Holmes's four convictions were for defrauding investors, not patients.

🔬 AMS Core Frame
Theranos combined two different harms: inaccurate medical testing and false representations used to raise capital. They overlap factually but not automatically in law. The jury convicted Holmes on investor counts, acquitted her on the patient conspiracy and three patient wire-fraud counts, and could not reach verdicts on three other investor counts.

FACT
Theranos claimed to have developed proprietary technology that could run comprehensive blood tests using only a small fingerprick sample, instead of a standard venous blood draw. The claim drove the company to a $9 billion valuation and made Holmes, on paper, the youngest self-made female billionaire in the US as of 2015.
FACT
The SEC later alleged that Theranos's proprietary analyzer could complete only a small number of tests and that the vast majority of patient tests were run on modified or standard commercial analyzers. The company had not merely “failed to finish” every promised capability; investors were shown a materially different picture of what worked at the time.
