A good source to investigate domain names and their potential value is Sedo, a full service domain clearinghouse, including a domain auction.
Recently Escom sold Sex.com through Sedo for a record $13 Million. At least we now know what the top end is. Here is the press release:
Online domain specialist Sedo.com today announced the sale of the Sex.com domain name for a record $13 million. The sale was brokered by one of Sedo’s senior domain brokers, Jeffrey Gabriel, who conducted a three-month search for a buyer on behalf of Escom in accordance with an order issued by the United States Bankruptcy Court for the Central District of California.
“We are very pleased with the fact that the bankruptcy process provided a basis for the sale of the domain free and clear of all creditor liens, which has now yielded this record breaking price,” stated Del Anthony, CEO/President of Escom.”
“It is very rare when a domain name of this quality and value becomes available, and we are pleased that Sedo was involved with this historic event. To our knowledge, this sale represents the single largest recorded price paid for a domain name in the history of the Internet,” said Gabriel.
Escom acquired the domain in 2006 for a then record $11.5 million. Sedo’s recent $13 million sale of Sex.com now holds the record as the largest domain sale to date, which further demonstrates the continued demand for premium domains and the increasing value of Sex.com.”
