Alphabet (GOOGL) Leads Tech Sell-Off on AI Investment Concerns

U.S. tech giants faced selling pressure on Monday, June 22, 2026, amid investor concerns over escalating AI infrastructure spending and uncertain returns. Google parent Alphabet (GOOGL) plummeted 6% intraday, its largest single-day drop since May 2025, wiping over $256 billion in market capitalization. Amazon (AMZN) declined 4.8%, with Meta Platforms (META) and Microsoft (MSFT) each falling nearly 3%. This collective $248 billion market value loss follows reports of key AI talent departures from Google DeepMind, including Nobel laureate John Jumper joining Anthropic and a VP moving to OpenAI, raising concerns about Google's AI competitiveness. Analysts note a market divergence, favoring AI spending beneficiaries. Memory chip giant Micron Technology (MU) surged 5.8% to a record high after partnering with Anthropic, underscoring robust demand for AI infrastructure components, contrasting with cloud providers' capital expenditure burdens.
