Batista, whose fortune early last year was put at USD 30 billion, is now merely a multi-millionaire, Forbes magazine said, announcing his delisting from the ranks of the world's wealthiest yesterday.
The comedown followed the implosion of Batista's heavily leveraged mining, energy and logistics empire, wiping out more wealth in less than two years than all but a handful of the world's billionaires even have to their credit.
"Batista, who told Forbes in 2010 he would become the world's richest man, is now worth less than USD 900 million," the magazine said.
Meanwhile his power generation company MPX said last week it would change its name to cut the link it has with Batista.
