I was carrying out some research on prior published domain name acquisitions and sales and came across this information Global Warming Solutions, Inc. published in their SEC – 10Q report

On October 23, 2019, the Company acquired the domain name, “www.cbd.biz” and other intangible assets from Paul Rosenberg and Overwatch Partners, Inc., for $100,000.

Subsequently in the same statement

On May 8, 2021, the company ceased all operations relating to CBD sales. The website “www.cbd.biz” has since been shut down. All operations pertaining to CBD sales have been divested and discontinued. The domain and all other assets associated with CBD sales was transferred to Green Holistic Solutions, Inc., in exchange for 18 million shares of Green Holistic Solutions, Inc. Green Holistic Solutions, Inc., is controlled by Paul Rosenberg and Michael Hawkins, both of whom are a significant shareholder of the Company.

It is unclear to me that this was purely a domain name sale in 2019, as there was an active website operating on CBD.biz, and thus the “intangible assets” element of the $100,000 USD sale could be a significant portion relating to the acquisition price.

The highest known published sale of a .BIZ domain name is e.biz sold for $66,001 USD at SEDO back in 2009 and it doesn’t resolve. The highest known CBD domain name sale published is CBD.co sold for $50,000 USD in 2018 via Grit Brokerage.
