Berkshire Hathaway Builds $20B+ Alphabet Stake Under New CEO Abel

What happened

In Q1 2026, Berkshire Hathaway more than tripled its Alphabet stake to approximately 58 million shares worth about $16.6 billion. In June, Abel executed a $10 billion private placement, purchasing 28.6 million new shares directly from Alphabet at a discount to market prices, split evenly between Class A and Class C stock. This brought the total Alphabet position above $40 billion, surpassing Berkshire's long-held Coca-Cola stake. The buying spree occurred as Abel overhauled Berkshire's equity portfolio in his first quarter as CEO, purchasing $15.9 billion in stocks while selling $24.1 billion, reducing total holdings from 42 to 29 positions. Beyond Alphabet, Abel initiated or significantly expanded positions in Delta Air Lines ($2.6 billion), The New York Times ($1.3 billion), Lennar ($877 million), and Macy's ($55 million).

Why it matters

The Alphabet investment represents Abel's most assertive technology bet since Apple and signals a willingness to deploy capital aggressively in sectors Warren Buffett largely avoided. Alphabet's business model aligns with Berkshire's traditional preference for durable competitive advantages: Google Search and YouTube generate consistent profits, while Google Cloud posted 63% revenue growth in Q1 to $20 billion, with operating income roughly tripling to $6.6 billion. The cloud backlog nearly doubled to over $460 billion, representing years of contracted AI infrastructure demand already locked in. The private placement structure provided Berkshire a discount while giving Alphabet capital to fund its planned $180 billion+ in AI infrastructure spending. The Delta investment reverses Buffett's pandemic-era airline exit, suggesting Abel sees sustained profitability in the sector. The portfolio concentration-top 10 holdings now represent roughly 91% of total value-indicates Abel will focus capital on high-conviction ideas rather than broad diversification.

Bigger picture

Abel's moves reflect broader industry shifts toward AI infrastructure investment and cloud computing demand. Alphabet is spending aggressively to build data center capacity as customers reserve computing power for AI workloads, with the $460 billion backlog indicating multi-year committed demand. The $80 billion equity raise Alphabet conducted, in which Berkshire participated, underscores the capital intensity required to compete in AI infrastructure. Abel's operational background-he previously ran Berkshire's energy subsidiary-may influence how he evaluates technology investments compared to Buffett's traditional approach. The portfolio overhaul, with 16 positions eliminated in one quarter, suggests Abel is willing to move quickly and concentrate capital rather than maintain legacy holdings. Berkshire held over $397 billion in cash and Treasury bills at quarter-end, giving Abel substantial dry powder for additional investments.

What to watch

Monitor whether Abel continues building the Alphabet position or begins deploying Berkshire's massive cash stockpile into other technology investments. Alphabet's capital expenditure execution and AI infrastructure utilization rates will determine whether the $180 billion+ spending plan translates to returns. Regulatory scrutiny of Alphabet's search and advertising business remains ongoing and could impact the investment thesis. Track whether Abel's other new positions in Delta, The New York Times, Lennar, and Macy's receive additional capital or represent opportunistic value plays. Berkshire's 13F filings reflect holdings as of quarter-end, so current positions may differ materially. The shift from 42 to 29 holdings suggests further portfolio concentration could continue, making each quarterly filing more significant for understanding Abel's strategy.
