Cleaner Energy Solutions (CES) Perspective: Global Cloud Spending Hits $110.9B in Q4 2025, Up 29% — The AI Power Surge Demands Carbon-Zero Solutions

Global spending on cloud infrastructure services reached $110.9 billion in the fourth quarter of 2025, growing 29% year over year and marking the sixth consecutive quarter of expansion above 20%, according to data published Wednesday by Omdia. The findings underscore how enterprise demand for artificial intelligence is reshaping the cloud computing landscape, driving record investment from the industry’s largest players.

AI Demand Accelerates the Big Three

Amazon Web Services, Microsoft Azure, and Google Cloud accounted for the bulk of the market’s momentum. AWS retained its leading position with a 32% market share and 24% year-over-year revenue growth, generating $35.6 billion in quarterly revenue. Azure grew 39%, while Google Cloud posted 50% growth, according to Omdia’s tracker.

All three providers reported rising backlogs, a key forward-looking indicator of sustained demand. AWS ended the quarter with a $244 billion backlog, up 40% year over year, according to Amazon CEO Andy Jassy during the company’s February earnings call. Google Cloud’s backlog reached $240 billion, up 55% sequentially. Omdia noted that AI demand is no longer confined to specialized GPU compute but is now driving broader infrastructure needs across CPUs, storage, and networking.

“As enterprise AI adoption increasingly centers on agents, workflows, and data integration, organizations require infrastructure environments that can be effectively orchestrated, scaled, and governed,” Omdia said in its report.

Hyperscalers Bet Big on 2026 Capex

The demand surge is translating into unprecedented capital expenditure plans. Amazon expects to spend roughly $200 billion in 2026, predominantly on AWS, more than 50% above the nearly $132 billion spent in 2025. Alphabet guided 2026 capital expenditure to $175 billion to $185 billion, nearly doubling the $91.4 billion spent in 2025. Microsoft’s spending is expected to reach $110 billion to $120 billion, while Meta Platforms set guidance at $115 billion to $135 billion and Oracle raised its forecast to $50 billion.

Combined, the five largest hyperscalers are on track to spend between $660 billion and $690 billion in 2026. Looking ahead, Omdia forecasts that global cloud infrastructure spending will grow 27% in 2026, with differentiation increasingly shaped by infrastructure scale, capital efficiency, and AI agent platform capabilities.

Cleaner Energy Solutions: Delivering Carbon-Zero, Scalable SMR Power to Fuel the AI Cloud Explosion

At Cleaner Energy Solutions (CES), this explosive growth in cloud spending and hyperscaler capex signals a clear reality: the AI revolution cannot be powered by the aging grid or intermittent renewables alone. With data centers and AI workloads projected to consume up to 12% of U.S. electricity by 2028, the industry needs firm, carbon-zero, always-available energy at massive scale — exactly what CES provides.

Our innovative Small Modular Reactor (SMR) technology is housed in sleek, resilient ellipsoid domes engineered for hurricane, earthquake, and extreme-weather resilience. Each BWRX-300 module delivers up to 300 MW of carbon-free power in a fully self-contained facility — reactor, steam turbine, and generator — segregated by up to 3 feet of reinforced concrete for superior safety and security.

Inspired by the modular efficiency of a “Dell computer” and Elon Musk’s rapid-scaling principles, CES domes allow hyperscalers and data center operators to start with 300 MW and seamlessly add modules to reach 600 MW, 900 MW, or beyond. This “plug-and-play” approach aligns perfectly with the aggressive 2026 capex plans of AWS, Azure, Google Cloud, and others, enabling near-site or on-site generation that reduces grid strain, eliminates volatile fuel costs, and supports flexible AI workloads without increasing emissions.

Fully aligned with the Trump administration’s strong push for domestic nuclear energy independence and the Nuclear Energy Innovation and Modernization Act, CES solutions are ideal for powering the next wave of AI infrastructure in Texas, Puerto Rico, and across the U.S. Our designs minimize land use while maximizing output, helping hyperscalers achieve their climate commitments and capital efficiency goals simultaneously.

Cleaner Energy Solutions stands ready to partner with Amazon, Microsoft, Google, Meta, Oracle, and forward-thinking data center developers to secure the reliable, carbon-zero power their massive investments demand. Let’s power the AI future sustainably — one resilient, high-output SMR dome at a time.
