AI 算力成为新瓶颈，Alphabet 的 800 亿融资和巴菲特入场，说明基础设施投资逻辑变了——做 AI 基础设施或关注资本流向的投资者值得关注。
Alphabet 宣布将通过多种方式筹集 800 亿美元，用于 AI 基础设施投资，其中巴菲特旗下伯克希尔哈撒韦投资 100 亿美元。这表明 AI 发展的瓶颈已从需求、模型或产品转向算力供应。Alphabet 的筹资方式包括承销股票、强制可转换优先股、伯克希尔私募以及 400 亿美元的 ATM 计划。伯克希尔的参与为此次筹资提供了耐心资本的背书，凸显了 AI 基础设施投资正从软件式回报转向类似铁路、电网等重资产模式。

Alphabet to raise $80B from share sales to fund AI spending splurge, Berkshire to invest $10B
Very bullish news, as it shows again the limiting factor is no longer demand, models, or products, but compute supply.
For years, the cleanest story was excess cash, buybacks, and software-like returns; now the story is closer to railroads, power grids, and fabs, where whoever can finance the bottleneck may own the toll road.
Berkshire’s $10B placement gives the raise a stamp of patient capital.
Alphabet is not simply selling $80B of common stock straight into the market tomorrow for AI capex. It is using a mix of underwritten stock, mandatory convertible preferred, Berkshire private placement, and a $40B ATM program, with about $30B of that ATM tied to employee equity tax mechanics.
