US investment in AI infrastructure is expected to hit $1.4 trillion next year, up from $800 billion in 2026, former White House AI czar David Sacks told the G20. He compared the scale to 19th-century railways and said AI could drive reindustrialisation, jobs and power-grid upgrades.

Chapel Hill: Investment in artificial intelligence infrastructure in the United States is expected to reach USD 1.4 trillion next year, accelerating an expansion compared with the building of railways in the 19th century, a former White House technology official has told G20 representatives.

David Sacks, a former White House AI czar, said that about USD 800 billion was being invested in AI-related capital expenditure in the United States this year.

“And that number is expected to be USD 1.4 trillion next year,” Sacks told a G20 session on emerging technologies.

The estimates were repeatedly being revised upwards as companies expanded data centres and the computing capacity needed to develop and operate artificial intelligence, he said.
