Tesla and Alphabet led a broad selloff as investors questioned heavier AI spending and awaited earnings from Microsoft, Amazon and Meta next week.
The Magnificent Seven erased about $797 billion in market value on Thursday, their biggest one-day drop since April 2025, extending losses to roughly $2 trillion from record highs reached in late May. Tesla sank 15% and Alphabet fell 7.1% as investors focused on higher capital spending plans and uncertainty over returns on AI infrastructure investment ahead of earnings from Microsoft, Amazon and Meta next week.
