Alphabet Inc. is raising $80 billion through a stock sale to fund its artificial intelligence infrastructure. Berkshire Hathaway has already agreed to invest $10 billion as part of the plan.

The company says the funds will support data center expansion and AI compute capacity to meet surging demand from enterprises and consumers.

Alphabet is racing to keep pace with rivals Amazon, Microsoft, and Meta. The four hyperscalers are expected to spend over $700 billion on AI infrastructure this year, with forecasts topping $1 trillion by 2027.

CEO Sundar Pichai cited "compute capacity" as his biggest concern, highlighting challenges in power, land, and supply chains.

The offering includes $30 billion in underwritten stock, $10 billion from Berkshire, and $40 billion through an at-the-market program. Goldman Sachs, JPMorgan, and Morgan Stanley are managing the sale.

Alphabet’s stock has more than doubled over the past year but is up just 18% year-to-date.
