It is very possible that the owner has a recurring payment in place, or that the owner renews after it expires. Because GoDaddy gives a redemption period like all registrar, many domain name investors will actually allow their domains to go through auction to see what the “market value” is of a domain name and THEN renew it. It sucks if you’re the buyer thinking you won the auction. It happens often, unfortunately.
If the domain name is not with any auction house partner (I think that’s what you’re saying), then you can use a drop catch service anytime: https://www.domainsherpa.com/domain-name-backorder-services/ They do not make your order public information as NameJet and others do by sharing how many bids are placed on a domain name and thereby driving interest.
A domain name that reaches expired status and is not renewed by the owner will be listed at an auction service (see FAQ for exception to this rule). The domain name does not immediately go into auction, but is immediately listed on the partnered auction service with an auction scheduled for the near future. Such a domain name will be exclusive to that specific auction service.
