Wall Street Slows Amid AI Migration Fears and Renewed Tariff Angst

Stocks on Wall Street fell on Monday, as fears of artificial intelligence-related disruptions and the collapse of the US Supreme Court’s ruling on Friday sent investors fleeing riskier stocks.
A broad selloff sent all three major US stock indexes down more than 1% at the closing bell, as risk appetite was dampened by a combination of lingering fears about potential disruptions from artificial intelligence technology and Trump’s ambiguous statements on trade policy, which fueled market volatility during the first year of the president’s second term.
Financial stocks fell 3.3%, while software-related firms fell 4.3% amid continued fears of AI disruption.
“The question with AI is twofold: How much will it cost, and who will be disrupted?” said Tom Hainlin, national investment strategist at US Bank Wealth Management in Minneapolis. “You’ve seen the market react to the headlines, ‘sell first, check later.’
He added: “It’s a vision of what could happen as opposed to what happened.”
On Friday, the nation’s highest court ruled 6-3 that Trump had exceeded his presidential authority by imposing corresponding tariffs under the economic emergency law, a decision that drew criticism from the president, who threatened a temporary 15% tax on all sales, even though he has reached trade deals with many of America’s partners.
Gold prices, benefiting from a flight to the safe zone, rose 2.6%.
“The decision of the Supreme Court was unexpected,” said Hainlin. “But layering these uncertainties on top of each other, the tense political situation in the Middle East, tax uncertainty, and AI migration may lead investors to a broader risk reassessment.”
