CNBC article doesn't say Icahn bought in, sounds like a BS post.
But he does say:

There are too many exotic, leveraged products and one day these securities are going to blow up the market, Carl Icahn says.
The billionaire investor says, "The market itself is way over leveraged," and at some point could "implode."
But for now, he believes, "This thing will probably bounce back."
