As of July 2015, The Undertaker of WWE does not have any matches scheduled, but is likely to appear at Wrestlemania 32. This event will take place at AT&T Stadium in Arlington, Texas on April 3, 2016. Tickets are not yet officially on sale.
Mark Calaway, who performs as The Undertaker, is 50 years old and has had a very limited schedule of appearances for several years. He has not appeared on WWE televised programming or at house shows since 2013. His lone regular appearance has been his annual match at Wrestlemania.
While no match has been announced for Wrestlemania 32 at this time, it is a likely possibility for the Undertaker's next match as he has appeared at the event almost every year since 1991. Some possible opponents are Sting, John Cena and Kevin Owens. It is unknown at this time what plans the WWE has for the Undertaker at Wrestlemania 32, however, and there is as of yet no official confirmation that he will be performing.
In recent years, tickets to Wrestlemania have gone on sale in early to mid-November. They are usually sold through Ticketmaster and range in price from about $35 for the most inexpensive seats to about $2,000 for ringside seats.
