Monopolies are illegal because they exploit consumers by fixing prices. Ticketmaster has a large portion of the ticket selling market, but it is not a monopoly. A monopoly has no competitors. Ticketmaster, however, has many competitors, such as Vivid Seats, Prime Sport, Etix, or Ticketfly. Monopolies also exploit consumers and set high prices to increase profits. Ticketmaster sells tickets at reasonable prices. Instead of calling Ticketmaster a monopoly, it can be stated that it is a popular ticket seller.
