Ticketmaster and Eventbrite take 50% as fees of what they charge on a ticket. After an artist pays for their own security, their staff and promoters, venue rental costs, insurance, and a whole host of other expenses, they pocket so little. For musical artists, the record labels take their profits to pay back the so-called loans they give to the artists when the artists first start out.
