Legendary energy trader John Arnold who compounded triple-digit returns for a decade sits down with CNBC’s Melissa Lee to discuss the AI power crisis, what makes a great trader, and the gambling epidemic hitting young Americans.

Arnold started at Enron (“I earned my MBA there — you learn more on the way down”), built Centaurus into one of the most successful energy hedge funds ever, and now sits on Meta’s board helping navigate the infrastructure challenges of AI.

He breaks down why $650 billion in Big Tech capex is causing “whack-a-mole” supply chain chaos, why hyperscalers are now bringing their own power (BYOP), and where he sees opportunity in energy — from advanced geothermal to next-gen nuclear.

Plus: His research showing 60-80% of high school and college boys gamble daily, why the CFTC’s prediction market ruling is dangerous, and his warning: “Stop making access to vice lower.”
