Alphabet completes $84.75 billion equity raise, the largest in US corporate history, to fund AI infrastructure

· by Pondero Newsdesk

The short version

Alphabet closed a $84.75 billion equity capital raise in early June 2026, upsized from an initial $80 billion, with Berkshire Hathaway anchoring $10 billion of the deal. The capital funds AI compute buildout as Alphabet projects $180-190 billion in 2026 capital expenditures.

Alphabet completes $84.75 billion equity raise, the largest in US corporate history, to fund AI infrastructure

Alphabet closed what the SEC filing calls the largest equity capital raise in US public-company history on June 4-5, 2026. The final figure settled at $84.75 billion after the initial $80 billion announcement drew enough institutional demand to be upsized within 24 hours.

What happened

The raise has three parts. A $30 billion underwritten public offering priced Class A shares at $355.20 each and Class C shares at $351.80 each, alongside 167.5 million depositary shares representing two new series of 6.25% mandatory convertible preferred stock at $50 per depositary share. Berkshire Hathaway committed $10 billion in a concurrent private placement, split between Class A and Class C shares at a slight discount to the public offering price. A separate $40 billion at-the-market share program rounds out the total; sales under that program are not expected to begin until the third quarter of 2026, per Alphabet's Form FWP filed with the SEC.

The offering of common stock was expected to close June 4, 2026, and the depositary shares on June 5, 2026, per the same SEC filing. Goldman Sachs, J.P. Morgan, and Morgan Stanley served as lead book-running managers.

The previous record stood at $70 billion, set by Brazil's Petrobras in 2010 and held for 16 years, per TechCrunch's June 3 report.

Why it matters

Alphabet earmarked the proceeds for AI compute infrastructure: data centers, custom silicon (TPUs and Axion CPUs), cooling systems, and network capacity for training and serving AI models, per Alphabet's June 2026 investor presentation. The company's 2026 capex guidance sits at $180-190 billion, up from its earlier $175-185 billion estimate, with CFO Anat Ashkenazi signaling further increases in 2027 from that base. The $84.75 billion equity raise covers roughly half the 2026 capex plan in a single transaction.

Berkshire Hathaway's participation is the detail worth tracking for AI tool operators and enterprise buyers. The firm built its reputation on avoiding businesses that require open-ended capital intensity. Its $10 billion commitment signals a view that AI infrastructure returns are durable enough to justify that scale of capital, not just a short-cycle bet. Alphabet's Q1 2026 revenue was $110 billion, up 22% year-over-year, per TechCrunch's reporting on the raise, which is the financial base against which the preferred dividends will be paid.

For the first time in more than two decades, Alphabet chose to raise equity rather than rely on its own cash generation or debt. The mandatory convertible preferred shares carry a 6.25% annual dividend and convert to common stock no later than May 15, 2029, per the SEC filing. Choosing convertibles over straight debt suggests Alphabet preferred managed dilution over fixed interest obligations at this scale.

What to watch next

The $40 billion ATM program launches in Q3 2026, subject to market conditions. How quickly Alphabet draws on it will indicate how urgent the capital need is versus how much the company is managing dilution against the stock price.

Alphabet's late-July earnings call will be the first public checkpoint on how the capital is flowing into physical infrastructure. Any gap between the "unprecedented customer demand" framing from the June investor presentation and the Q2 capital expenditure figures will tell operators whether the buildout is tracking to plan.
