Big Tech's AI Spending Spree Sparks Investor Cash Burn Concerns

Investors are increasingly scrutinizing Big Tech's free cash flow as companies ramp up AI infrastructure spending amid high borrowing costs, raising concerns about whether massive investments will generate sufficient returns. Microsoft was rewarded for funding its ambitions without constant capital market access, while Alphabet, Amazon, and Meta faced pressure as infrastructure budgets strained their balance sheets. Alphabet reported negative free cash flow of $9.07 billion despite Google Cloud revenue doubling to $30.71 billion, with slowing search and YouTube ad growth triggering a 13% stock drop. Amazon burned $42.4 billion on a trailing twelve-month basis due to $77.26 billion in capital expenditures, while Meta posted negative free cash flow of $2.12 billion and raised its capex guidance. Experts are divided on whether concerns are justified. Morgan Stanley notes companies can create value if investments exceed capital costs, citing Walmart's negative free cash flow from 1973-1986 that yielded 33% annual returns. Others argue established tech firms have strong balance sheets and existing operations as buffers, unlike unprofitable AI startups such as OpenAI and Anthropic.
