Berkshire adds $10 billion investment in Alphabet, backing the largest equity offering in U.S. corporate history

Berkshire Hathaway will invest $10 billion in Alphabet’s $80 billion capital raise to support AI infrastructure expansion.

The deal is split evenly between Alphabet Class A common shares and Class C capital shares, priced below the stock’s closing level.

This is the largest single equity capital raise in U.S. corporate history, drawing major market attention.

The move adds confidence to Alphabet’s AI buildout and could lift Berkshire’s stake higher among its top holdings.
