Where Is the Money Going?

1. Data Center Construction (Largest Share)

Four giants’ data center construction is reshaping the US power grid:

  • US data center grid transformer crisis continues
  • By 2030, US data center power investment expected to triple
  • Amazon, Microsoft building hyperscale AI data centers across multiple states

2. AI Chip Procurement

NVIDIA GPUAll fourHundreds of thousands
Google TPUGoogle internalSelf-developed
AWS TrainiumAmazon internalReduce NVIDIA dependency
AMD MI SeriesMultipleCost-effective alternative

3. Agent Infrastructure Investment

Q1 2026 earnings show all four giants listing AI Agents as core growth drivers.

AWS 28% Growth: Fastest in 15 Quarters

Drivers:

  1. AI workload migration: More enterprise AI inference/training moving to cloud
  2. Bedrock multi-model strategy: Customers can use Claude, GPT, Llama simultaneously
  3. Agent infrastructure: Bedrock Agents attracting enterprise AI Agent builds

Google Cloud 63% Growth But Supply Constrained

Google Cloud’s 63% growth is impressive but officially supply constrained, meaning:

  • Demand exceeds capacity
  • GPU/TPU resources tight
  • May delay some customers’ AI projects

Meta’s $10B Increase Strategy

Additional $10B mainly used for:

  • Llama model training: Maintain open-source competitiveness
  • AI social features: AI-generated content and interaction
  • Metaverse + AI: AI-driven virtual reality experiences
