The New York and New Jersey attorneys general have subpoenaed FIFA over concerns about misleading ticketing practices that have led to exorbitant prices for matches that will be held at MetLife Stadium in New Jersey.

The announcement from New York attorney general Letitia James and New Jersey attorney general Jennifer Davenport comes as part of a probe into how FIFA has been handling ticket sales for the World Cup. Specifically, the AGs are looking into ticketing practices for the eight matches that will be held at MetLife, including the World Cup final on July 19. They are also looking into FIFA’s use of a dynamic pricing model, under which the cost of tickets change in real time based on demand and availability. The AGs are being supported in their investigation by the New York City Department of Consumer and Worker Protection (DCWP).

“New Yorkers have been waiting years for the World Cup to come to their backyard, and they deserve a fair shot at affordable tickets,” James said in Wednesday’s statement announcing the probe. “No one should be manipulated into paying sky-high prices for seats, and fans should be able to trust that the tickets they purchase will be the ones they receive.”
