Tech giants commit $710B to AI Capex, driving mixed market reactions and record highs for S&P and Nasdaq.

Amazon, Microsoft, Google, and Meta announced a combined $710 billion investment in AI capital expenditures for 2026, signaling strong growth ambitions. Google's CEO Sundar Pichai highlighted being "compute-constrained," which boosted stocks like Apple, Amazon, and Google that are already monetizing CapEx. Meanwhile, Meta and Microsoft saw stock declines due to longer-term monetization timelines. The Fed's recent divided vote and oil price shifts add complexity to market dynamics, with investors watching upcoming earnings and economic data for further signals.
