Layer 1: Applications — Meta’s 3.58B User Demand Engine

The Key Insight

Meta’s apps aren’t just distribution. They’re AI workload. Every feed refresh, every recommendation, every message creates AI inference load. This captive demand provides something no hyperscaler has: guaranteed utilization at scale.

The Family of Apps

App DAU Key AI Use
Facebook 2.1B Feed recommendations, content moderation
Instagram 2.0B Reels AI, Advantage+ ads
WhatsApp 1.0B Business AI agents
Messenger 1.0B Meta AI assistant
Threads 275M Content recommendations

The Demand Equation

  • Daily Active People: 3.58B
  • Daily AI Workloads: ~100+ billion
  • AI Inference Demand: ~350B+ daily
  • Utilization: GUARANTEED

Why This Matters for Infrastructure

Hyperscalers (Google, AWS, Azure)

  • Must find customers for capacity
  • Utilization varies with demand
  • Compete on price/features
  • Demand is external (not guaranteed)

Meta (Captive Demand)

  • 3.58B users generate demand daily
  • Apps are AI inference machines
  • Every user action = AI workload
  • Demand is internal (guaranteed)

The Financial Proof

Family of Apps Q4 2025: $58.9B revenue, $30.8B operating income — a 52% operating margin that funds the infrastructure build-out.
