Currently, the most expensive sports arena on Earth is MetLife Stadium in New Jersey. Opened in 2010 as the Meadowlands Sports Complex, this feat of architectural and engineering prowess took three years to complete and cost a staggering $1.6 billion, according to Investopedia.

Like all the best things in New Jersey, the MetLife stadium is mostly made up of stuff from New York that spilled over the turnpike. It serves as the base of operations for the NFL’s New York Jets and Giants, with special design elements built in to make transitioning from one team to another a relatively easy job. It features seating for 82,500 attendees, making it the largest arena in terms of seating currently operating in the United States, as well as four locker rooms, 1,350 solar panels, ten high definition 54-foot LED pylons, and, not for nothing, decent chili dogs.

That said, MetLife’s place at the top of the financial pile is not long for this world. In 2020, Allegiant Stadium is set to open outside in Paradise, Nevada and serve as the new home to the Las Vegas Raiders, formerly of Oakland, as well as the University of Nevada, Las Vegas’ football team, the UNLV Rebels. Despite its less spectacular 71,000 seat capacity, the facility has a projected total cost of around $1.9 billion, or roughly, according to the World Population Review for 2020, the GDP of Gambia.
