Wall Street is growing increasingly concerned about the capital expenditures of hyperscale data center operators. The four major hyperscalers—Amazon.com (AMZN.US), Microsoft (MSFT.US), Alphabet (GOOGL.US), and Meta Platforms, Inc. (META.US)—are projected to have a combined capital expenditure slightly exceeding $200 billion in 2024. At the current trajectory, this figure could approach $700 billion in just two years. The aggregate free cash flow of these four companies declined to $200 billion last year from $237 billion in 2024, primarily consumed by data center construction. Investors are left questioning: what happens to this spending if the economic landscape shifts?
History offers a partial answer from an unexpected source. In 1930, the then-dominant telecommunications giant AT&T Inc (T.US) was in the midst of the largest private infrastructure build-out in its history, with annual construction costs reaching a staggering $585 million—an almost unimaginable sum at the time. Even as the Great Depression, the most severe economic downturn in history, ensued, characterized by collapsing GDP and soaring unemployment, the Bell System never halted its construction. Remarkably, it maintained an uninterrupted dividend payment of $9 per share from 1929 through 1942.
This counter-cyclical behavior did not stem from profit optimism but from a survival instinct rooted in "monopoly logic." As the embodiment of network effects, the Bell System's very rationale for existence and its competitive moat would have crumbled had it stopped expanding. Continued construction became the only option to sustain the system's operation. This structural logic—that stopping was more perilous than continuing—finds a precise echo in today's AI arms race. The actions of tech giants are shifting from aggressive growth to defensive investment.
Amazon.com CEO Andy Jassy's recent characterization of the AI opportunity is, in essence, not a growth report but a statement of competitive risk: in the current technological explosion, the risk of being left behind far outweighs the cost of over-investment. Currently, the capital expenditure of these five giants (including Oracle) has maintained a staggering annual growth rate of 72% since mid-2023. Their total spending now accounts for 2.2% of U.S. GDP. This investment is no longer about optimizing existing businesses but about securing a core, hub-like position in the future digital landscape, akin to the "telecommunications infrastructure" of the past.
However, modern hyperscale computing centers face a more severe financial depreciation challenge compared to the Bell System of yesteryear. AI assets depreciate extremely rapidly, with hardware typically depreciating at an annual rate of 20%. This implies that by 2025, annual depreciation expenses alone could potentially consume all profit growth for these companies. While free cash flow metrics are deteriorating, spending commitments remain unchanged.
Unlike the Bell System, which operated with government franchises and guaranteed rates of return, today's tech giants compete in a fully open, global oligopolistic market involving multiple players. Faced with tariff volatility, interest rate uncertainty, and fragile market sentiment, these companies have expressed firm stances in their guidance, yet their financial buffer has significantly thinned.
As the infrastructure imperative evolves into a survival race, capital expenditure becomes the last item to be cut—not the first. Whether this highly leveraged expansion is a ticket to a new era or a trigger for the next financial crisis has become a focal point for global investors.
