Alphabet said Monday it will raise $80 billion through a stock sale to fund its AI compute buildout, anchored by a $10 billion investment from Berkshire Hathaway. The Google parent is pairing that private placement with $30 billion in underwritten offerings and a $40 billion at-the-market program for Class A and Class C shares scheduled to begin in the third quarter. The package is one of the largest equity raises ever announced by a megacap technology company, and it lands less than two months after Google lifted its 2026 capex guidance to as much as $190 billion.
The company framed the raise as supply-driven. Alphabet said the proceeds will fund investments in its world-class AI compute infrastructure to meet what it called unprecedented customer demand for Gemini and related services.
“The company is experiencing strong demand for its AI solutions and services from enterprises and consumers, at levels that are exceeding the company's available supply”— Alphabet, Company statement
The $30 billion underwritten tranche includes $15 billion in depositary shares representing mandatory convertible preferred stock. Goldman Sachs, JPMorgan Chase and Morgan Stanley are joint book-running managers on the underwritten offerings, with Goldman acting as placement agent for the Berkshire private placement. Alphabet said the structure lets it scale spending while retaining a healthy balance sheet.
Key facts
- 01Alphabet will sell $80 billion in stock to fund AI infrastructure, with $10 billion coming from Berkshire Hathaway.
- 02Google raised 2026 capex guidance in April to $180-$190 billion, up from $175-$185 billion.
- 03The package includes $30 billion in underwritten offerings, $15 billion in mandatory convertible preferred, and a $40 billion at-the-market program starting in Q3.
- 04Alphabet, Microsoft, Meta and Amazon are on pace for more than $700 billion in combined 2026 capex, with Wall Street modeling above $1 trillion in 2027.
- 05Goldman Sachs, JPMorgan Chase and Morgan Stanley are joint book-running managers for the underwritten offerings.
Google revised its 2026 capex range to $180 billion to $190 billion in April, up from a prior estimate of $175 billion to $185 billion. At Google I/O on May 19, CEO Sundar Pichai said compute capacity is what keeps Google executives up at night.
Pichai framed the constraint as physical rather than financial.
“Be it power, land, supply chain constraints, how do you ramp up to meet this extraordinary demand for this moment?”— Sundar Pichai, Google CEO
The broader hyperscaler bill is steeper still. Alphabet, Microsoft, Meta and Amazon are tracking toward more than $700 billion in combined capex this year, with Wall Street analysts modeling total AI capex above $1 trillion in 2027. Alphabet has also leaned heavily on debt markets, raising more than $30 billion in a global bond issuance in February and roughly $11 billion in sterling and Swiss francs in Europe, on top of a $25 billion bond sale in November.
Berkshire Hathaway's involvement is the headline-grabbing detail. The investment firm has been building a position in Alphabet since the third quarter of last year, disclosing a $4.3 billion bet in November that has since grown to roughly $20 billion, making Alphabet one of its top holdings behind Apple. The additional $10 billion at the announced terms deepens what is already one of Berkshire's largest technology positions in years.
Alphabet stock has more than doubled in the past year, outperforming every megacap peer as investors rewarded the rollout of Gemini upgrades and Google's AI search monetization. Shares slipped in extended trading on Monday after the offering was announced, a typical reaction to large secondary issuance that dilutes existing holders.
The financing also clarifies how the hyperscalers intend to bridge the gap between operating cash flow and the scale of their AI commitments. Operating cash flow alone is not covering 2026 capex at any of the top four; debt issuance and now equity issuance are filling the difference. For a company that has historically funded everything from cash, an $80 billion equity raise is a notable shift in capital structure.
The open question is whether revenue tied to AI compute scales fast enough to justify the spend before investors lose patience. Alphabet has not broken out Gemini-specific revenue, and the company's framing of demand exceeding supply is a claim without a public number attached. If returns on the buildout lag the depreciation schedule on $190 billion of capex, the math gets uncomfortable quickly.
For the AI market, the read-through is that the largest buyers of GPUs, power, and land are not slowing down — they are reaching for new pools of capital to accelerate. That is bullish for Nvidia, for the data-center supply chain, and for any vendor that sells into hyperscaler capex. It is also a signal that the era of AI infrastructure funded entirely from free cash flow is over, and that equity markets are now part of the funding stack. Whoever ends up owning Gemini's future revenue is paying for the compute up front.
