US Stock Market Today: S&P 500, Dow, Nasdaq Open Lower; Meta Erases $100 Billion In Value On AI Concerns

US equity indices opened lower on Tuesday as the S&P 500 and Dow slipped, driven by a sharp drop in Meta Platforms. The social‑media firm fell about 5%, erasing roughly $100 billion of market value after analysts raised doubts about the near‑term payoff of its AI spending.
The slide underscores investors’ caution toward tech stocks that are heavily tied to AI expectations. A softer start can dampen risk‑on sentiment, especially as the market also weighs the Fed’s policy outlook and upcoming corporate earnings.
Market participants will watch earnings from other AI‑focused companies and any new guidance from the Federal Reserve. Further updates on Meta’s AI strategy or regulatory developments could influence the broader market in the days ahead.
