Does Mark Cuban think AI spending could cause a US debt bubble?

Yes. Mark Cuban said the US literally could get into a debt bubble because AI hyperscalers are borrowing more than they make while the federal deficit keeps rising. With the 10-year Treasury yield near 5.2% and the country already paying about $1 trillion a year in interest, he said a move to 6%, 8% or 10% would force something to give, and the borrowers would compete for the same money.

Cuban said NVIDIA is effectively subsidizing half the industry because it has the cash to do so.
Cuban said Meta is borrowing more than its cash flow, and that the AI build-out runs through an uncertain private-credit market.
Cuban cited Ray Dalio's view that the US is already late in a debt cycle.
