AI Infrastructure Spending to Eclipse U.S. Defense Budget by 2027

The five largest AI hyperscalers — Alphabet, Amazon, Meta, Microsoft, and Oracle — are projected to spend $1.1 trillion on AI infrastructure in 2027 alone. According to Morgan Stanley, their combined capital expenditures will reach roughly 3.2% of U.S. GDP, surpassing the nation’s defense budget as a share of the economy for the first time. This follows a rapid series of upward revisions, with spending climbing from ~1.5% of GDP in 2025 toward 2.5% in 2026 before crossing the defense threshold.

This is more than a spending milestone. It marks a historic inflection: AI is transitioning from breakthrough technology into foundational infrastructure. And when AI becomes infrastructure, clean, reliable electricity ceases to be a utility and becomes its indispensable supplier. The deeper reliance on always-on baseload power reveals the inadequacy of legacy grids and intermittent renewables, demanding an entirely new class of energy infrastructure.

Cleaner Energy Solutions Was Built for Precisely This Moment

Our Small Modular Reactor (SMR) technology — featuring proven designs from Westinghouse and GE housed inside sleek, resilient ellipsoid domes — delivers up to 300 MW of carbon-zero power per module with a minimal land footprint. Factory fabrication enables rapid deployment. The modular “Dell computer”-style architecture means operators can start with a single dome and scale to 600 MW or 900 MW simply by adding identical units — exactly the way hyperscalers scale GPU clusters.

Each dome incorporates up to 3 feet of reinforced concrete segregation for safety, passive systems, and proven resilience against hurricanes and earthquakes. The result is compact, high-density, always-on clean power ideally suited for direct colocation with AI data centers or for strengthening national and regional grids.

From Puerto Rico to the Mainland: Scalable, Resilient Power

Puerto Rico’s projects near San Germán, Arecibo, and Morovis already demonstrate this model: resilient, scalable SMR facilities that support both grid stability and the island’s 100% clean energy mandate by 2050. The same approach scales across the mainland United States.

With U.S. data center construction spending already surpassing public transit infrastructure and AI-related electricity demand projected to reach 12% of total U.S. consumption by 2028, the bottleneck is no longer compute — it is electrons. The hyperscalers are investing trillions in the digital layer. The physical layer that powers it must now match that ambition.

The Path Forward: Advanced Nuclear for the AI Era

Under the current administration’s focus on advanced nuclear, domestic energy dominance, and streamlined regulation, projects like ours are positioned to move fast. Cleaner Energy Solutions offers the safe, scalable, minimal-footprint infrastructure the AI era requires.

The future of AI will be built on reliable, carbon-zero power. We are building that future — one resilient ellipsoid dome at a time.
