U.S. Stocks Mixed as Big Tech Loses $797 Billion in Market Value

Wall Street faced a demanding stretch of corporate results and macroeconomic indicators as investors weighed the path of monetary policy against ballooning infrastructure investments in the tech sector.

Big Tech Capital Spending Sparks Market Jitters and Capital Flight

The enthusiasm surrounding the scale and duration of the artificial intelligence boom has begun to hit selective turbulence. Bloomberg calculations indicate that the seven largest American technology companies lost $797 billion in market capitalization since April. Although the group’s tracking index reached record highs in late May, it subsequently retreated 11 percent, wiping out $2 trillion in market value from that peak.

Corporate announcements from both Alphabet and Tesla confirmed that capital expenditures are set to climb further. Alphabet reported a jump in second-quarter costs that led to negative cash flow for the first time in its history as a publicly traded company. Meanwhile, Elon Musk’s pledge to accelerate capital expenditures to the highest possible level triggered a 15 percent drop in Tesla shares during a single Thursday session, marking its worst trading day since March 2025. Alphabet shares similarly tumbled 7.1 percent in their worst performance since May 2025.

Attention shifted heavily to the Federal Reserve meeting as traders looked for guidance on interest rate trajectories.

Uncertainty also surrounds the communication approach of the central bank under its new leadership. Analysts at BNP Paribas noted that the possibility of an unexpected rate increase cannot be entirely ruled out. FedWatch data from CME showed that traders pinned the probability of a quarter-point bump at 33.7 percent heading into the decision.

Crude Oil Fluctuations and Their Ripple Effects Across Global Markets
