Article Summary
Just days before the 2015 Super Bowl was played in Glendale, Arizona, the average
price of a ticket on the secondary resale market was $10,352, more than three times the
average price for the 2014 game. People who were able to purchase tickets at face value
directly from the NFL paid prices ranging from $800 to $1,900 per ticket. The day
before the game, ticket broker StubHub listed its least expensive seat at $8,049, while
the most expensive seat was priced at more than $65,000.
