Revealed! 3 single letter .coms these giants are using!

English has 26 letters, does that mean there are 26 single-letter .com domains? Actually, no. Currently, only three single-letter .com domains have been registered: x.com, z.com, and q.com, all of which are used by giant companies. The rest of the single-letter .com domains are reserved.

It is understood that there have been only three instances of direct open registration for the 26 single-letter domains (in 1993, 1997, and 1999), and each time only one domain was registered.

X.com

- In 1993, a relatively mysterious company, Weinstein & DePaolis, registered X.com.

- In 1999, Elon Musk, founder of Tesla and SpaceX, acquired the domain and created the online financial platform X.com.

- In 2000, X.com and PayPal merged, initially retaining the X.com name until it was renamed PayPal in June 2001.

- In 2002, eBay acquired PayPal for $1.5 billion, and since then, X.com has not been used.

- In 2017, Musk reacquired X.com from PayPal.

- In 2023, Musk redirected X.com as a 301 redirect to the official domain twitter.com, which he had previously acquired.

Z.com

Z.com was registered in 1997. Visiting the domain shows that the platform primarily offers web hosting services, including virtual hosting, WordPress hosting, and domain registration.

Q.com

Q.com was registered in 1999 and currently redirects to the website quantumfiber.com. This platform specializes in intelligent fiber optics, similar to broadband services in China.

Some say that single-letter .com domains are the nobility of all domains, as precious as gold that won't depreciate. Currently, x.com, q.com, and z.com are all used by giant corporations. The other 23 single-letter .com domains are considered even more precious due to their scarcity, and they are not open for registration. It remains to be seen which lucky individuals will own them in the future.
