It seems like every year a NFL stadium is getting an upgrade or renovation. Millions and in some cases billions of dollars are put into making sure the teams have the best playing field. According to NBC Los Angeles, it seems that the most expensive stadium is right here in California. SoFi Stadium, home of both the LA Chargers and the LA Rams, is reported to have cost $4.9 billion.
The only other stadium that comes close to that is AT&T Stadium in Texas, home of the Dallas Cowboys. Their stadium cost $1.3 billion when it was built back in 2009.
