About John Arnold

John Arnold shocked the hedge fund world in 2012 when, at just 38 years old, he announced he would no longer manage other people's money.

A hugely successful energy trader, Arnold once worked at Enron, earning the disgraced company a reported $750 million the year it went bankrupt.

From its ashes, Arnold built his own hedge fund, Centaurus Advisors.

In recent years Arnold has invested in solar farms and deepwater oil developments in the Gulf of Mexico.

He and his wife Laura's Arnold Ventures focuses on reforming criminal justice, higher education, health, infrastructure and public finance
