With 50 percent of the concrete foundation complete, Athletics President Marc Badain said the team should have a guaranteed maximum price for its under-construction Las Vegas baseball stadium “shortly,” and confirmed owner John Fisher’s recent comments that construction costs have risen above $2 billion

Following a presentation to the Las Vegas Stadium Authority on Thursday, Badain said the public should start seeing some “vertical work” on the stadium by the end of September or the beginning of October.

“Some of that prep work has already been done,” Badain said. “There are only certain things that you can do until the permits are in place.”

He said construction is still on schedule for the opening of the 2028 season.

The 33,000-capacity ballpark was initially billed at $1.5 billion and raised to $1.75 billion last year.
