Alphabet Raises $80 Billion for AI Infrastructure, Berkshire Hathaway Invests $10 Billion

Alphabet announced a $80 billion equity financing plan to fund massive artificial intelligence infrastructure expansion, the company's largest capital raise on record. The financing comprises a $30 billion underwritten public offering, a $40 billion at-the-market program beginning in Q3 2026, and a $10 billion private placement exclusively underwritten by Berkshire Hathaway, which will increase its holdings of Alphabet's A and C class shares, bringing total investment above $26 billion and making Google Alphabet's largest position in Berkshire's stock portfolio.

Alphabet's 2026 capital expenditure guidance stands at $180 billion to $190 billion annually, with roughly 75% directed toward AI infrastructure including chips, servers, and data centers. The company cited demand for AI solutions exceeding current supply capacity, signaling the financing addresses acute market demand rather than precautionary capital needs.
