It looks like the high value 21.com domain name is going to become a casino. I noticed a change (via DomainTools) yesterday when the domain name transferred registrars from eNom to SafeNames. When I visited 21.com, I saw a coming soon landing page announcing plans for the domain name and website:
From what I can see, the domain name appears to have been registered privately at Enom. I am unsure if the domain name was recently acquired or had been held by the same registrant under privacy.
I reached out to the domain registrant to ask for a comment about the domain name. Specifically, I asked if the domain name was recently acquired and if they could share the purchase price to buy 21.com. I heard back from the company and was told they do not provide the information I requested.
In my opinion, 21.com is likely a seven figure domain name. It will make a great brand name for a casino.
