6. Stadium SoFi
The place is in Glendale, USA.
Completed Cost: $5.5 billion * Year: 2020
The groundbreaking at SoFi Stadium in Inglewood, California, took place in the fall of 2016. It took almost four years to finish due to a number of permit challenges and the intervention of Mother Nature, but the 298-acre entertainment complex was open to the public in 2020.

Despite an estimated construction cost of $5.5 billion, SOFI Stadium is the home of two NFL teams: the Los Angeles Rams and Chargers. Put another way, the stadium should be paid for in a few years based just on the earnings from the NFL season. The stadium then naturally holds concerts and other events.
