The broader market is facing a harsh reality check as aggressive artificial intelligence capital expenditure plans from hyperscalers like Alphabet and Tesla triggered a brutal tech sell-off, wiping roughly $500 billion off their combined market caps and leaving investors demanding clear timelines for AI monetization.

Markets & Economics#

The S&P 500 and Nasdaq suffered their sharpest one-day drops in a month, tumbling 1.2% and 2.2% respectively, as investors aggressively rotated out of tech megacaps. Reignited inflation fears further rattled markets after Brent crude broke the $100 per barrel mark for the first time since May following Houthi attacks in the Red Sea and an ongoing U.S.-Iran conflict. These inflationary pressures pushed the 10-year Treasury yield up to 4.7%, its highest level since January 2025, stressing credit markets and raising doubts about imminent Fed rate cuts. On the economic data front, CNBC’s Rick Santelli broke down June home sales, which managed to exceed market expectations despite the tightening rate environment.
