Ken Griffin steered Citadel from a post‑Enron fallout into a commodities juggernaut that now rivals traditional energy firms.

After Enron’s collapse, Griffin seized distressed assets, turning Citadel into a leading trader of oil, gas and metals. The firm now manages over $40 billion in commodities exposure.

Citadel’s expansion reshapes market liquidity, pushing rivals to adjust hedging strategies. Its sheer volume pressures price discovery across global exchanges.

The firm’s growth signals a shift where hedge funds increasingly dominate physical energy markets, altering competitive dynamics and regulatory scrutiny.
