Big Tech earnings hit by AI spending concerns; Nasdaq drops 2% as Alphabet, Tesla report cash burn
Wall Street sank after the first major Big Tech earnings reports of the season, with the Nasdaq falling over 2% on July 23 following releases from Alphabet and Tesla. Both companies reported negative free cash flow in Q2 and signaled higher capital expenditure ahead, spooking investors who had been demanding proof that massive AI spending translates to revenue growth. Alphabet's stock fell 7%, dragging the communications services sector down 5.2%, while Tesla tumbled 14.5% on negative free cash flow of $1.1 billion—a stark reversal from the $146 million positive FCF a year prior.
Alphabet raised capex guidance to $195–205 billion for 2026 (previously $180–190B) and warned of even higher spending in 2027. Tesla CEO Elon Musk defended the aggressive buildout, saying "we should be spending on capex as fast as we can without it being too wasteful," but acknowledged the company is burning cash to scale factories and data centers. The broader anxiety reflects investor focus on whether the $725 billion in annual AI infrastructure spending across hyperscalers will yield near-term revenue expansion or compress margins before demand materializes.
The market test continues through late July, with Microsoft and Meta reporting July 29, and Amazon and Apple on July 30. Analysts are watching for evidence that Azure, AWS, and Google Cloud can sustain or accelerate growth above 30–35% to justify the capex. Goldman Sachs data shows global hyperscaler AI spending hit $725 billion in 2026, a 77% year-over-year jump, raising the stakes: if earnings miss, a "margin squeeze" scenario could unfold where depreciation costs rise faster than software monetization.
