The world's richest man sent shockwaves through the platform by suggesting a site called X.com could be on the cards.

It comes as Musk, 51, faces a fiery legal battle against Twitter for dramatically pulling out of a $44billion buyout.

The SpaceX and Tesla founder simply responded, "X.com" when asked by another user whether he would consider launching his own social network if he's not forced to go ahead with the Twitter deal.

At the moment, the website displays nothing but a single 'x'.

The tease came after it was revealed that Musk had sold 7.92million Tesla shares worth $6.9billion in case he's forced to buy Twitter.
