That gain puts Icahn in elite company. John Paulson's Paulson & Co. made about $15 billion shorting subprime mortgages in 2007; George Soros' Soros Fund Management made an estimated $1 billion shorting the British pound in 1992; David Tepper's Appaloosa Management made about $7.5 billion mostly by going long financial stocks in 2009; and Bill Ackman's Pershing Square Capital made about $3 billion betting on General Growth Properties from 2008 to 2014.

When asked if the Apple trade was one of the greatest of all time, Icahn declined to comment on the profit but told CNBC.com this, "I will certainly say Apple is one of the greatest companies of all time."
