Tickets to the NCAA Final Four have been sold out for months, snapped up by dealers looking to make a resale profit, and fans hoping their team would reach the final weekend of the tournament.
Three-game passes, which combine both Saturday's semifinals and Monday's national championship game, have a face value of $200. But as the tournament went on, thousands of tickets changed hands online, and prices rose and fell like shares on the stock exchange.
Like all markets, this one is driven by supply and demand: Fans of losing teams flood the market to sell their tickets, and fans of winners pick them up.
