In the days leading up to Super Bowl week, there has been very little talk about the actual game, with the “Deflategate” controversy dominating most of the headlines. The scandal, however, hasn’t lessened fans’ interest in seeing the New England Patriots vs. Seattle Seahawks in person, considering ticket prices on the secondary market have been increasing.

Less than two days after the 2015 Super Bowl matchup was set, the average seat at the University of Phoenix Stadium in Glendale, Arizona was being priced at $4,174.50, according to TiqIq. As of Friday morning, tickets could be had for an average of $4,833.25.

StubHub, the largest secondary ticket marketplace, has seen a slow increase in ticket prices. Tickets were sold at an average of $2,984 on the day after the NFC and AFC championship games. On Friday, the average price moved to $3,074. The day before the conference title games were played, Super Bowl tickets were being sold for an average of $3,134.

As ticket prices increase, 2015 could see Super Bowl seats being sold for historical amounts of money. No Super Bowl has ever averaged secondary market ticket prices at $5,000, since TiqIq began tracking such information in 2010.

The average ticket selling price at StubHub is almost 21 percent higher than last year’s average price of $2,527. The average 2013 Super Bowl ticket sold for $2,525, though ticket prices usually drop in the last few days leading up to the game. Last year, the average Super Bowl ticket price at TiqIQ was listed at $4,064, but seats went for just an average of $2,567 on the day of the contest.

Not only could tickets be priced higher than ever in 2015, but this year has also seen an increase in the number of tickets sold on the secondary market. Sales at StubHub are up 91 percent from last year’s game between the Seahawks and Denver Broncos at MetLife Stadium. According to StubHub, 20 percent of those sales have come from the state of Washington.

The Patriots and Seahawks have two of the most fervent fan bases in the NFL. The Patriots have sold out every home game, including the playoffs, since Dec. 26, 1993. After their Super Bowl winning season, the Seahawks had a 99 percent season-ticket renewal rate. Seattle also has the highest average secondary-ticket market prices of any team in the league.
