Alphabet priced an $84.75 billion equity capital raise on June 29, the largest in US corporate history. The company upsized the offering from $80 billion and stated it will deploy the proceeds toward AI infrastructure and global compute capacity expansion.
Three-Part Structure
The raise is structured in three tranches, according to Insider Monkey. The first is a $30 billion underwritten public offering split between common stock and mandatory convertible preferred shares. Alphabet priced 25.5 million Class A shares at $355.20 each and 25.5 million Class C shares at $351.80 each, alongside 167.5 million Series A and Series B depositary shares at $50 each.
The second tranche is a $10 billion private placement anchored by Warren Buffett’s Berkshire Hathaway. The third is a $40 billion at-the-market (ATM) program set to begin in Q3 2026.
Alphabet upsized the Class A/C stock portion to $18 billion from $15 billion and increased the depositary share portion to $16.75 billion from $15 billion. The company expects net proceeds from these two buckets to be approximately $17.8 billion and $16.6 billion, respectively.
The Capital Market Shift
The raise signals a structural shift in how Big Tech finances its AI buildout. Rather than relying solely on internal cash generation, Alphabet is turning to external equity markets at scale. The Berkshire Hathaway anchor investment lends credibility to the thesis that AI infrastructure spending will generate returns.
JPMorgan’s midyear outlook, released June 24, projects global AI-related capital expenditures will reach $5.5 trillion through 2030, with hyperscaler capital expenditures reaching $650 billion in 2026 and exceeding $1.1 trillion in 2027. The bank projects AI-related debt financing alone will reach $4.1 trillion as loan-to-cost ratios rise.
Where This Sits in the AI Spending Cycle
Alphabet joins a crowded capital-raising field. SambaNova is in talks to raise $800 million to $1 billion at a $10 billion valuation. OpenAI closed a $122 billion round earlier this year. Anthropic, valued at $965 billion, is preparing for an IPO.
The Bank for International Settlements warned in its 2026 annual report that the AI investment boom could trigger credit market disruption comparable to the 2008 financial crisis, citing circular financing and poorly disclosed asset pledging. High-grade US tech bond credit spreads widened to 0.79% in June 2026 as bond investors signaled skepticism about the sustainability of the current spending trajectory.
Alphabet’s decision to raise equity rather than issue more debt may reflect awareness of that skepticism. Equity dilutes existing shareholders but avoids adding to the debt pile that the BIS flagged as systemic risk. Whether $84.75 billion in fresh equity translates into proportional AI revenue growth remains the question every investor in this cycle is pricing.
