AI Safety Warnings Trigger Wall Street Selloff

Nvidia shares slipped 3% to reach a three-week low, while Amazon saw its valuation contract by more than 1%.

Investors are now balancing these industry-specific anxieties against the looming threat of Federal Reserve interest rate hikes, creating a volatile environment for the remainder of the week.
