The overall U.S. sports market was worth over $71.1 billion in 2018. By the end of 2022, it’s expected to reach $80.2 billion, according to a report from PricewaterhouseCoopers. As the sports industry is continuing to grow, expansion teams are being added to the National Hockey League (NHL), National Football League (NFL) teams are moving cities, and a lot of exciting construction projects are in the works for new stadiums.

Gate revenue accounted for $19.3 billion of the sports market in 2018. To keep fans coming and to make the experience as enjoyable as possible, teams have been shelling out billions of dollars to build new stadiums. Here are five of the most expensive sports stadiums in the U.S.

1. Los Angeles Stadium

Team: Los Angeles Rams, Los Angeles Chargers

Cost: $4.9 billion

Opened: 2020

Key features:

• The Super Bowl is set to come to the venue in 2022, it’s lined-up to host the 2028 Olympics, and it’s the most likely candidate to host the 2026 World Cup Final if the United States, Mexico, and Canada’s bid to co-host is approved.

• The most noticeable design feature of the stadium is its expansive, transparent roof that will cover not only the entire playing field and seating bowl but also an adjacent pedestrian plaza and a proposed 6,000-seat theater capable of hosting high-profile events like the Academy Awards.
