According to page F-38 of a recently published SEC filing, there was a domain name with a book value of $1.5 million, which is being amortized at $100,000 per year. As of December 31, 2020, it had accumulated $533,000 worth of amortization (5.33 years). While the domain name wasn’t identified on that page of the SEC filing, page 218 does mention Enjoy.com.
Some additional digging via the WHOIS history at DomainTools indicates that the nameservers of Enjoy.com changed from DreamHost to AWS in the period between August 29, 2015 and September 11, 2015. This timing is entirely consistent with the above amortization, since 5.33 years before December 31, 2020 is early September 2015. Furthermore, Archive.org shows a change in the website around that time.
If accepted by DNJournal, this would rank #3 for publicly reported domain name transactions in 2015.
