Microsoft, Google, Amazon, and Meta have collectively committed $218 billion in capital expenditure for 2026 — an unprecedented bet on AI infrastructure. With data center construction timelines stretching 3–4 years and power constraints emerging as the binding constraint, the competitive dynamics of the AI era are shifting faster than analysts can model.

• NVIDIA's H200 and Blackwell allocations are sold out through Q4 2026; AMD's MI300X gaining traction as enterprises diversify supply chains.
• Power procurement has become the new moat — Microsoft's 10GW nuclear partnership with Constellation Energy is a 20-year competitive advantage.
• Google's TPU v5 custom silicon now powers 60% of internal inference workloads, reducing external GPU dependency and margin drag.
• OpenAI's revenue run rate hit $2.7B/month in April; enterprise API business growing 18% month-over-month as corporate deployment accelerates.
