<h1>US bets on $1tn Saudi-backed AI boom as debt mounts, power costs rise and bubble fears grow</h1> The US President is relying on artificial intelligence investment, including a pledged USD 1 trillion from the Saudi crown prince, to drive economic growth and stock market gains.

Major US investment and technology executives highlighted AI and power as dominant growth areas, underscoring strategic economic dependence on cross-border capital and energy resources to support AI expansion.
