The NameJet auction for SportsPicks.com just ended, and the final price was $25,660. The auction had a total of 207 bids from 163 bidders. SportsPicks.com was created in April of 1995, and it appears to have recently expired, and as such, it was not a private seller auction.
I was involved in the auction and would have been a buyer in the $10,000 range, but I have concerns with respect to US laws involving gambling. In addition, there are regulations about gambling advertising, so generating revenue may have been difficult on this particular domain name.
Currently, sports betting is legal in just a few areas in the United States (like Las Vegas). New Jersey governor Chris Christie has announced that his state is going to defy federal law and permit sports betting.
According to NameBio, FreePicks.com sold for $91,250 in April of 2006 on SnapNames.
