Investing.com -- Citi is projecting a staggering $801 billion in combined 2027 capital expenditure across Alphabet, Meta Platforms, and Amazon, warning that the scale of AI infrastructure spending will push all three hyperscalers into negative free cash flow territory in both 2027 and 2028.

The brokerage firm materially raised capex forecasts across the board ahead of Q2 2026 earnings season — results that Citi also expects to beat consensus on the top and bottom lines.

Citi stated that "we are materially raising CapEx projections, resulting in negative FCF in '27E & '28E for each" of the three companies. The bank raised its 2027 Alphabet capex estimate by approximately 21% to $308 billion, lifted its Meta forecast by roughly 22% to $205 billion, and increased its Amazon projection by about 12% to $288 billion.

Meta's elevated spending is specifically tied to its target of approximately 14 gigawatts of compute capacity, underscoring the raw physical scale of the AI arms race now underway among the world's largest technology platforms.

Negative FCF at companies of this size, generating hundreds of billions in annual revenue, reflects just how capital-intensive the AI infrastructure buildout has become.

Citi frames this not as a sign of distress but as a deliberate strategic bet, noting that "the focus remains on each company's investments in AI compute and infrastructure given continued strong demand trends."

The bank is raising its Google Cloud Platform projections to +68.5% year-over-year growth in Q2 2026 and +93.5% growth to $190 billion in 2027. Notably, Citi is for the first time incorporating Tensor Processing Unit sales into its GCP revenue model, with approximately $62 billion of TPU revenue baked into the 2027 estimate. This shift reflects Citi's view that Google's custom AI chip business has matured into a meaningful, trackable revenue stream rather than an internal cost center.

For Amazon Web Services (AWS), Citi projects growth of +32.5% year-over-year in Q2 2026, +33.5% for full-year 2026, and +40% in 2027. The bank attributes the acceleration to "accelerating AI adoption and more compute capacity support AWS growth," adding that "infrastructure investments remain a key focus" for investors heading into the print.

Beyond the cloud and capex story, Citi also sees near-term upside from improving advertising and e-commerce conditions. The bank wrote that "improving online advertising and eCommerce trends — based on checks (see our Cannes and ad expert call notes) should result in better-than-expected revenue and profitability trends for 2Q and potentially 3Q guidance."

Channel checks from the Cannes advertising festival and a separate ad expert call inform that view, suggesting the macro backdrop for digital ad spending has firmed meaningfully heading into the summer.

The combination of stronger-than-expected near-term results and sharply higher long-term capex creates a nuanced setup for investors. Bulls can point to Citi's conviction that Q2 beats are coming and that AI demand justifies the investment cycle.

Bears will note that negative free cash flow projected across three of the world's most profitable companies simultaneously, beginning in 2027, represents a meaningful shift in the financial profile of the hyperscaler trade.

All three companies are expected to report Q2 2026 results in the coming weeks, and Citi's note suggests the prints themselves may be the easier part of those calls to digest. The harder question, which investors will likely press management on, is how each company is thinking about the return timeline on capital spending that now runs into the hundreds of billions annually.
