CNBC reported on June 1, 2026 that Alphabet plans to sell $80 billion in stock—including a $10 billion investment by Berkshire Hathaway—to fund AI compute infrastructure as demand for its AI products exceeds available supply.

Equity program

  • Alphabet said proceeds will fund world-class AI compute infrastructure to meet unprecedented customer demand.
  • Berkshire Hathaway agreed to a $10 billion private placement: $5 billion of Class A shares at $351.81 and $5 billion of Class C shares at $348.20, per CNBC.
  • $30 billion in underwritten offerings, including $15 billion in depositary shares representing mandatory convertible preferred stock.
  • $40 billion at-the-market program for Class A and Class C shares, expected to begin in the third quarter.
  • Goldman Sachs, JPMorgan Chase, and Morgan Stanley are joint book-running managers; Goldman is placement agent for the Berkshire private placement.

Capex and capacity context

  • Alphabet revised 2026 capex guidance to $180 billion–$190 billion, up from $175 billion–$185 billion in April, CNBC said.
  • CEO Sundar Pichai told CNBC that compute capacity—power, land, and supply-chain ramp—keeps executives up at night.
  • CNBC cited expectations that Alphabet, Microsoft, Meta, and Amazon will spend more than $700 billion combined on capex in 2026, with Wall Street estimates that total AI capex could exceed $1 trillion in 2027.

Debt market backdrop (CNBC)

  • Alphabet held a global bond issuance in excess of $30 billion in February and raised roughly $11 billion in sterling and Swiss francs in Europe, following a $25 billion bond sale in November, per CNBC.

Market reaction

  • Alphabet shares more than doubled over the past year, CNBC reported, but slipped in extended trading on Monday after the announcement.
  • Prior to Monday, Berkshire's Alphabet stake was worth about $20 billion, one of Berkshire's top positions; Berkshire began building the position in the third quarter of 2025.
