Alphabet announced plans to raise $80 billion to expand its artificial intelligence infrastructure.

Berkshire Hathaway committed $10 billion to the initiative through a private placement. The capital will scale compute capacity to meet unprecedented demand from enterprise and consumer users. Current demand for Google’s AI services exceeds its existing supply.

The fundraising includes $30 billion in public offerings. Alphabet will also raise $40 billion through an at-the-market program.

Berkshire Hathaway will split its investment evenly between Alphabet’s Class A and Class C shares. This move increases Berkshire’s stake and signals an endorsement of Alphabet’s long-term strategy.
