SoFi was the most expensive, by far, modern stadium at $5.5B, followed by MetLife at $2.03B. Spankee Stadium II is the highest baseball park at $1.82B.
How TF does this one manage to be $11-12B?
They tacked on a plan to re-develop the area around the stadium in like a six-block radius or something like that, somewhat similar to what the Rickettses did with Wrigleyville. It's an obvious ploy to make the deal unpalatable to the City and to Alameda County so they have more ammunition to leave and ammunition to use in court if they break their lease at the Coliseum (which runs through 2024 or 2025, as I recall) and get sued.
