SoFi Stadium — Los Angeles, USA

A $5.5 billion palace of innovation featuring a double-sided 4K video board that hangs from the roof like a spaceship over the field. The 70,000-seat stadium is the most expensive ever built, 83% costlier than #4 SoFi Stadium's own record, and its Infinity Screen spans 120 yards, 30% longer than the average NFL field.
