Is the Reign of Glencore’s Billionaire Copper King Near Its End?

Aristotelis Mistakidis is one of the world’s most powerful commodity traders. For nearly 20 years, the brash, hyperactive Greek known to everyone simply as “Telis” has ruled over the global copper market, buying and selling enough of the red metal to supply every factory in the U.S. twice over.

Today, the man who built Glencore’s reputation in copper is facing tough questions about how he did it. Mistakidis, who until recently ran both copper trading and mining, is under intense pressure after a string of investigations, problems and legal headaches.
