Microsoft and the AI sell-off: opportunity or value trap at the start of H2?

The market is penalizing Microsoft's AI capex spending before monetization is proven—a structural warning for all of Big Tech at the start of H2 2026.

The Fact

Microsoft (MSFT) records its worst month since December 2000, triggered by its massive AI capex spending (Economic Times, 06/30). MSFT underperformed the Nasdaq-100 in June amid a challenging Q2 close: high valuations on mega-cap tech, May core PCE at +4% (BEA), and the expected FOMC Warsh on July 29-30. Source articles (Economic Times, 06/30) confirm that the market is now pricing in the tension between U.S. macro resilience and the rising cost of financing tech equity positions—particularly through higher equity financing costs.

Our Take

The sell-off illustrates the 2026 structural tension: markets are penalizing hyperscalers' massive AI capex before Azure/Copilot monetization is proven. The mid-July arrival of DeepSeek V4 (a competitive open-weight model with low marginal cost) increases pressure on Azure OpenAI pricing. In a high-rate environment (Fed at 5.25-5.50%, potential H2 Warsh hike), the valuation premium for mega-cap tech is under growing pressure. The RSP/SPY divergence (equal-weighted S&P vs. giant caps) confirms rotation away from mega-caps. MSFT remains a high-quality AI proxy in the long term, but the optimal entry point depends on Q2 results in mid-July.
