“By 2040, the global demand for new infrastructure investment is $68 trillion. To put that price tag in perspective, it's roughly the equivalent of building the entire Interstate Highway System and the Transcontinental Railroad, start to finish, every six weeks—for the next 15 years... Even the world's largest tech companies, despite their billions in free cash flow, aren't equipped for this scale of investment. A single AI data center can cost between $40 billion and $50 billion.”

Deadline is 2040; the $68 trillion is a cumulative global infrastructure investment-demand estimate cited in the letter, to be judged against realized global infrastructure investment through 2040.
