Citing The Sun's website, the web-domain is rumored to be of very high value. Chances are, Musk has its own plans with the X.com domain.
Just to note, this is not the first time Musk has X.com. Previously, the 46-year-old billionaire had owned it in the 1990s.
However, in 1999, Musk sold the web page along with the Paypal money transfer company.
Elon Musk then built Tesla, a luxury electric car company and Space X, a space exploration business.
The Ph.D degree holder from Stanford University has also confirmed the purchase of X.com domain on his official Twitter account.
"Thank you PayPal for making me buy back X.com!" Tweet Musk on Twitter.
He said, there are currently no plans related to the domain. "However, this (domain) has sentimental value for me," he said.
Seeing the various businesses that run it, X.com domain can be used for anything. For example, the Hyperloop fast train design and proposals on electric jets.
Not to mention, Musk is currently reportedly working on the world's largest lithium-ion battery project built in Australia to save renewable energy.
Elon Musk had time to say, the goal of his company is nothing else in accordance with his personal vision, that is changing the world and humanity.
