Meta: Tripling AI CAPEX for Three Consecutive Quarters - Markets Still Underestimating the Scale

Context

At the beginning of 2026, Meta announced an annual CAPEX of $60-65 billion, doubling year-over-year. The question is no longer whether Meta is investing massively in AI, but whether the market is correctly valuing this level of investment and its translation into return on capital. Seeking Alpha published an analysis arguing that consensus estimates remain too conservative.

Data

Meta 2026 CAPEX guidance: $60-65 billion (vs. $32 billion in 2025, +100% YoY). Meta Q1 2026 revenue growth: +19% YoY to $42.3 billion (official results). Q1 2026 operating margins: 41% (vs. 35% in Q1 2025). Advantage+ (AI advertising platform): contributes to ~25% of Meta’s ad revenue according to sell-side estimates. Llama 4: downloaded over 500 million times since launch (Meta IR). META forward P/E: 23x (vs. 28.5x Nasdaq-100 average).

Analysis

The Meta paradox: the company is doubling its CAPEX while improving its margins. This is made possible by the accelerated monetization of Advantage+, which uses Llama models to optimize real-time ad targeting. In short, AI is already generating cash before the new infrastructure is fully operational. The analyst’s argument is strong: the market values Meta as a "high-cost" player when it should be valuing it as an "AI revenue machine" whose efficiency gains are underestimated in DCF models.

Probability-weighted scenarios

• Bull thesis confirmed (50%): Q2 2026 revenue exceeds expectations (+22%+), margins stable despite CAPEX → upward revision of consensus, META price toward $650+.
• Margin compression (35%): CAPEX exceeds guidance ($70B+), ad revenue disappoints in H2 → margins contract below 38%, downward earnings revision.
• Regulatory shock (15%): EU antitrust investigation or DMA impacts Advantage+ in Europe, weighing on 15-20% of revenue.

Portfolio implications

META is one of the few AI assets with a P/E below the Nasdaq average despite superior growth-an unjustified discount if margins hold. A tactical position ahead of Q2 results (mid-July) makes sense for investors with a 6-12 month horizon.

Risks & blind spots

Meta’s dependence on ad revenue exposes it to macro cycles: in a recession, SME ad budgets are the first to be cut. The EU regulatory risk is underestimated by the U.S. market.

To watch

Meta Q2 2026 results (mid-July); H2 CAPEX guidance; Advantage+ growth; European DMA decisions on Meta’s practices.
