Nasdaq plunges 5.52% into correction as AI trade retreats

The political backdrop is the immediate cause. Sen. Bernie Sanders of Vermont, who caucuses with Democrats, has called for a national data center moratorium, writing on X Wednesday evening that "Americans don't want Big Tech oligarchs wrecking the environment, gutting jobs and threatening humanity's future." Investors fear that stance could translate into policy that slows AI capex.

"Investors are stepping away until they get a better sense of the implications of the midterms around the AI capex cycle in particular, which is the biggest economic tailwind we've had going for us for the last, call it, three years," said Tim Holland, chief investment officer at Orion. Keith Lerner of Truist Wealth added that the size of the tech sell-off is now feeding into the broader market, with Caterpillar down 6%, JPMorgan 4% and Boeing and Nike each off 2%.

If you hold US stocks, a 401k-style retirement fund or crypto, this is the kind of day that shows up in your balance: the Nasdaq is now in correction, and AI-linked names that drove portfolios higher for three years are the ones being sold. The move is a rotation, not a crash — defensive areas and small caps also fell — but the market is repricing the political risk around data centers.

For readers in Tunisia, there is no direct local market impact, and no product or service availability is affected by Thursday's session. What matters is the signal: if the data-center buildout slows, the cost and pace of AI services, cloud capacity and chip supply could shift over the coming quarters. Watch whether the Democratic majority turns campaign rhetoric into concrete policy — that is the next catalyst.
