Why the US midterms sparked an AI stock selloff

Why it matters

The same thing, for different readers.

What it means for you

Opposition to local data centres, over water, power bills and noise, became a vote-winning issue and moved the stock market.

For lawmakers

Democrats now hold both houses of Congress and are expected to challenge the president's technology agenda, which BBC says investors read as a risk of more regulation.

The market reaction shows how much of the AI boom rests on expectations of future earnings rather than present ones.
