Alphabet Plans $80 Billion Equity Raise With $10 Billion Berkshire Hathaway Anchor for AI Compute Expansion

Alphabet announced on Monday that it plans to raise $80 billion in equity capital to fund AI compute infrastructure, making it the largest equity raise by a technology company in history. Warren Buffett’s Berkshire Hathaway will anchor the deal with a $10 billion private placement, according to CNBC.

The $80 billion breaks down into three tranches: $30 billion in underwritten offerings (including $15 billion in depositary shares representing mandatory convertible preferred stock), $10 billion from Berkshire Hathaway’s private placement, and $40 billion from an at-the-market offering program for Class A and Class C shares expected to begin in Q3 2026, according to CNBC’s reporting. Goldman Sachs, JPMorgan Chase, and Morgan Stanley are acting as joint book-running managers.

Why Alphabet Needs $80 Billion

“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 said in its statement, as cited by CNBC.

The capital raise comes after Alphabet revised its 2026 capital expenditure forecast in April to between $180 billion and $190 billion, up from a previous estimate of $175 billion to $185 billion, according to CNBC. When asked what keeps Google executives up at night during the April earnings call, CEO Sundar Pichai answered: “Compute capacity.”

“Be it power, land, supply chain constraints, how do you ramp up to meet this extraordinary demand for this moment?” Pichai said, according to CNBC.

The Debt Stack Behind the Equity

This is not Alphabet’s first trip to the capital markets in 2026. The company held a global bond issuance exceeding $30 billion in February, followed by roughly $11 billion in sterling and Swiss franc bonds in Europe, per CNBC. Those followed a $25 billion bond sale in November 2025.

The combined debt and equity capital raised across the past eight months exceeds $120 billion, all directed at the same constraint: physical compute capacity for AI workloads.

Berkshire’s Growing Position

Berkshire Hathaway has been building a position in Alphabet since Q3 2025. Prior to Monday’s announcement, the investment company’s stake in the Google parent was worth approximately $20 billion, one of its top holdings, according to CNBC. Berkshire first revealed a $4.3 billion bet on Alphabet in November 2025.

The $10 billion private placement signals Berkshire’s conviction that AI infrastructure represents a long-duration capital opportunity. At a time when public markets are questioning whether AI capex will generate returns, the most prominent value investor in history is doubling down.

The Capex Arms Race in Numbers

Alphabet, Microsoft, Meta, and Amazon are expected to pour more than $700 billion combined into capital expenditures this year, according to CNBC. Wall Street analysts estimate total AI capex could climb above $1 trillion in 2027.

Alphabet’s stock has more than doubled in the past year, outperforming all of the company’s megacap peers, as investors have endorsed the company’s AI spending and the revenue growth driven by Gemini upgrades, per CNBC. The stock slipped in extended trading on Monday, reflecting dilution concerns from the equity issuance, as noted by BeInCrypto.

The raise also underscores a structural reality for the AI industry: the companies best positioned to deploy AI agents at scale are still constrained by the physical infrastructure needed to run them. Power, land, chips, and data center capacity remain the binding constraints, even for the world’s most valuable companies.
