In fact, he presented his short thesis on hardware company Seagate this week at the Sohn Investment Conference.
So it's no surprise that Chanos is short Dell.
Wapner played a clip of Chanos on CNBC saying that he has no idea why companies like Silver Lake are even interested in Dell and gave Icahn the chance to respond.
"I've been on the other side of him [Chanos] many times and I've made fortunes being against him," said Icahn. "I don't mean this in a derrogatory way, but I don't see Chanos on the Forbes 400 list," he said.
Icahn went on to say that Dell was more than just a PC company, and that it's made important acqusitions in the software space that will make it a leader in cloud technology.
Fair enough, but then again, we know that Chanos loves to short companies that have made a lot of acqusitions.
Time will tell who's right.
