Amazon, Google, Meta and Microsoft have now poured more than $1.1 trillion into AI infrastructure since 2023, and the Financial Times calculates that another $745 billion will be added in 2026 alone. The pace is not slowing. RBC Capital analyst Rishi Jaluria told the publication there is “basically no end in sight for the growth in capex,” leaving investors to police a line between funding the next platform shift and starving the franchises that pay for it.

The grid pays, the ratepayer bleeds

The spending has already rewritten the economics of U.S. electricity. Utilities have committed billions to grid upgrades driven by data-center demand, then spread the cost across every customer on the system. The White House extracted a “ratepayer protection pledge” from hyperscalers, utilities and states, but no state has codified it into law. Oregon moved on its own in 2025 with the POWER Act, hiking bills 30 percent for loads above 20 megawatts while shaving 1.3 percent off residential rates, months before President Trump summoned the tech giants and told them to “pay their own way.”

Chipmakers choose the highest bidder

Memory makers are following the money. Micron, Samsung and SK hynix have redirected capacity toward high-bandwidth memory for AI clusters, where hyperscalers pay a premium, and away from commodity DRAM. The result is a consumer-memory shortage that began in 2025, hit PC builders first, and has now migrated into automotive and smartphone supply chains. Even Apple, with its legendary supplier leverage, has been forced to raise prices.

The balance sheet does not tell the whole story

Quarterly filings reveal roughly $1.65 trillion in future purchase obligations, 122 percent of the debt actually recorded on the four companies’ balance sheets. These commitments only crystallize as assets come online, but they represent real claims on future cash flow that standard leverage ratios miss. For now the cash machine hums: the quartet generated nearly $470 billion in revenue last quarter, led by Amazon at $200 billion, Alphabet at roughly $120 billion, Microsoft at $90 billion and Meta at $60 billion. That firepower keeps the buildout funded, but it does not make the obligations optional.
