You don’t often see two-letter dot com’s for sale, but 2 just went on auction today at Sedo.com. Both XU.com and ZR.com currently have bids of $80,000 each and have 6 days and 13 hours left on their respective 7-day auctions. It will be very interesting to see what they finally go for in 7 days.
Although both contain unpopular letters (i.e., X and Z), I would think that XU.com will end up selling for a higher price because it is pronounceable, which is rarely the case with 2-letter domains. The U in XU.com could stand for “unlimited,” while the R in ZR.com could stand for “resources.”
