The budget for Apple's upcoming "spaceship" campus in Cupertino has ballooned by $2 billion to a massive $5 billion, say five Bloomberg sources described as close to the project. Architectural firm Foster + Partners is reportedly looking to slash $1 billion from that budget, but that could still make the new campus more expensive than the new World Trade Center in New York City, which is expected to cost $3.9 billion. The attempt at cost-cutting is said to be behind the delay of the campus' opening until mid-2016.
