Does Ticketmaster sell more tickets for say a concert that got sold out the day they came on sale will get to nearer time of concert?

Ticketmaster typically does not resell or create additional available tickets. Some resale marketplaces or brokers who purchase tickets with the initial on-sale may resell tickets at varying prices closer to the event date, based on factors such as supply and demand, the popularity of the event, and any changes in seating configuration
