Hyperscaler Credit Scrutiny Emerges as the New AI Risk Vector

Microsoft shares declined after Morgan Stanley raised questions about hyperscaler creditworthiness, a notable rotation in the AI debate from capital-expenditure returns toward the funding structures financing them. Depreciation schedules, lease obligations and vendor-financing arrangements are increasingly the analytical battleground as data-center commitments extend multi-year. Parallel to the credit question is an accounting one: Amazon's stake in Anthropic has grown large enough to move consolidated earnings, and Alphabet's SpaceX position operates similarly, meaning private-company revaluations are now a recurring, non-operating driver of megacap EPS. That dynamic imports illiquid private marks into the earnings power of the most heavily owned public equities. Berkshire Hathaway's Alphabet position — the standout portfolio decision of the Greg Abel era — underscores how even value-oriented capital has been drawn into the complex. Separately, Apple faces its own margin arithmetic as memory-pricing headwinds prompted a rating downgrade, a reminder that AI-driven component inflation cuts both ways across the technology stack.
