Microsoft Has Invested Over $100 Billion in OpenAI, Nadella Says No One Wanted to Bet Then

为 OpenAI 累计投入超 1000 亿美元，纳德拉称微软当年投资时"没人愿意下注"

Microsoft has invested more than $100 billion in OpenAI, including a $13 billion original investment and Azure infrastructure costs, while the partnership has generated about $30 billion in revenue; the renewed non-exclusive agreement caps OpenAI’s revenue share at $38 billion cumulatively through 2030.

Why it matters: HKR-H/K/R all pass: this is not a product launch, but the Microsoft-OpenAI economics include three concrete figures on spend, revenue, and revenue-share caps, placing it in the 78–84 quality band.
