Alphabet has announced the largest equity raise in history tied to artificial intelligence infrastructure. The Google parent company is targeting $80 billion in total equity capital, anchored by a $10 billion private placement from Berkshire Hathaway.
The fundraising is structured in three tranches. There is $30 billion in underwritten offerings, the $10 billion Berkshire private placement, and up to $40 billion in at-the-market offerings expected to begin in the third quarter of 2026.
Berkshire Hathaway’s commitment is split evenly across two share classes. The conglomerate is purchasing $5 billion in Class A common stock at $351.81 per share, and $5 billion in Class C capital stock at $348.20 per share. This brings Berkshire’s total Alphabet holdings to approximately $32 billion. Notably, this marks one of Berkshire’s largest single equity bets since Warren Buffett’s retirement, signaling a deliberate endorsement of Alphabet’s AI strategy.
Alphabet is raising equity, rather than debt, to fund surging customer demand for cloud and AI services. This approach dilutes existing shareholders, a trade-off the company is accepting because it expects the return on invested capital to more than compensate.
The at-the-market offerings set to begin in Q3 2026 are the key element to watch. Unlike the fixed-sized underwritten offering and private placement, this $40 billion tranche gives Alphabet flexibility to sell shares opportunistically when the stock price is favorable.
