Microsoft Q4 Earnings: Anthropic Investment Yields $3.2B in One Quarter, OpenAI Remains Volatile

量子位 · wechat · 2026-07-30

Microsoft's latest earnings report reveals a $3.2 billion profit from its investment in Anthropic last quarter, contributing nearly 7% of the diluted EPS. This massive return is driven by Anthropic's soaring valuation, validating Microsoft's compute-for-capital strategy.

In contrast, Microsoft's returns from OpenAI have been highly volatile. Due to capital restructuring and accounting method changes, OpenAI's investment swung between massive losses and gains across recent quarters, contributing only $480 million in Q4. By backing multiple top AI labs, Microsoft hedges its bets while ensuring continuous revenue for its Azure cloud business.
