Alphabet filed an $80 billion equity raise Monday to fund AI infrastructure, splitting the deal three ways: $30 billion in underwritten public offerings, a $40 billion at-the-market program, and a $10 billion private placement to Berkshire Hathaway.

Berkshire Hathaway’s $10 billion anchor is the deal’s credibility signal. At that scale, Buffett’s firm is making a concentrated directional bet on Google Cloud’s AI infrastructure position, not a passive equity hedge.

One caveat on the structure: the $40 billion ATM tranche doesn’t fund data centers. Alphabet said those proceeds go primarily toward tax obligations on employee equity awards. The real infrastructure fuel is the $30 billion underwritten piece and the Berkshire placement.

What the money buys: Alphabet guided full-year 2026 capex at $180-190 billion, with Q1 alone hitting $35.7 billion. The company expects 2027 spending to climb higher still. Google Cloud was up 63%, almost entirely on enterprise AI demand, and it’s the asset this infrastructure bet is built around.

The equity raise is the tell. Alphabet generated $109.9 billion in quarterly revenue and still needs to sell stock. The Financial Times estimated Big Tech’s combined free cash flow will fall to $4 billion in Q3, from a $45 billion-per-quarter average since the pandemic. When that math runs out, you sell equity.
