Berkshire’s Greg Abel Commits $10 Billion to Alphabet’s AI Build-Out

Greg Abel, who took over as Berkshire Hathaway’s chief executive in January 2026, has committed $10 billion of the conglomerate’s cash to Alphabet through a private placement, deepening a position that has already paid off handsomely since Warren Buffett’s team first opened it. The deal was announced after the bell on Monday, June 1, as part of Alphabet’s plan to raise roughly $80 billion in equity to fund the AI infrastructure build-out. Alphabet’s shares closed at $366.46 on July 6, 2026, up from a 52-week low of $172.77, and the position Berkshire began building in the third quarter of 2025 has roughly doubled on price alone.

The investment cements a sharp break from Buffett’s six-decade reluctance to back technology companies. Abel has now turned Alphabet into one of Berkshire’s largest equity holdings in less than a year, and the Q1 2026 13F filing, his first as CEO, was the one that telegraphed the conviction. The private placement is the next, much larger move on the same wager.

What Berkshire Just Bought

Alphabet’s June 1 announcement of an $80 billion equity capital raise to expand AI infrastructure and compute was packaged as several offerings, and the Berkshire tranche was the largest disclosed piece. The private placement splits evenly between Alphabet’s two share classes: $5 billion of Class A stock (GOOGL) at $351.81 per share and $5 billion of Class C stock (GOOG) at $348.20 per share.

Those prices were struck at a discount to where the shares traded at announcement. Berkshire’s GOOGL purchase price was 5.5% below the stock’s market value, and the GOOG purchase was a 6.5% bargain. A “stealthy weekend call” from Goldman Sachs, the firm putting the package together, produced a “rapid signoff” from Abel, according to Bloomberg, in a structure that offered Alphabet a deep-pocketed anchor investor rather than a wholesale secondary offering.

Even after the $10 billion lands, Berkshire would still own less than 1% of Alphabet’s outstanding shares. The move does, however, lift Alphabet’s weighting inside Berkshire’s equity portfolio to 9.5%, up from 5.3% at the end of the first quarter, with the Berkshire stock portfolio valued at $341.5 billion including the new stake, per the $10 billion Berkshire committed to Alphabet’s capital raise at Morningstar. The new Class A shares alone would lift that tranche by 400%, with the Class C tranche up 26%.

From Quiet Stake to Top-Five Holding

The June 1 placement is the second big Berkshire vote of confidence in Alphabet in three weeks. In late May, Abel closed a $6.8 billion all-cash deal for homebuilder Taylor Morrison, his first major acquisition as CEO. Together, the two transactions put roughly $16.8 billion of Berkshire’s cash to work, against a cash pile that stood at $397.4 billion at the end of March.

Buffett’s team began the Alphabet position in the third quarter of 2025, when Berkshire bought close to 18 million shares. The position grew through the fourth quarter and then tripled in the first quarter of 2026. The Q1 2026 13F filing, Abel’s first, showed 54,249,798 GOOGL shares worth $15.60 billion, a 204% increase that lifted Alphabet to the fifth-largest position in Berkshire’s equity portfolio at quarter-end and 5.93% of the portfolio, per the Q1 2026 13F tracker at giantsight.com and a separate write-up of the Q1 13F disclosure that tripled Berkshire’s Alphabet stake at CNBC.

Once the new shares settle, Alphabet is expected to rank third or fourth in Berkshire’s equity lineup, on par with the long-held Coca-Cola stake, currently worth almost $32 billion. The speed of the move, from zero at the start of 2025 to a top-five holding inside fifteen months, is itself a signal. Buffett used to talk about waiting for “the fat pitch.” Abel has swung at the first one to cross the plate.

The $80 Billion AI Build-Out

Alphabet said the $80 billion raise will fund what it calls “world-class AI compute infrastructure to meet its unprecedented customer demand,” the language the company used in its June 1 announcement. The pitch is built on the same numbers Alphabet printed in its first-quarter earnings, released April 29. Total revenue rose 22% to $109.9 billion. Google Cloud, the unit most exposed to enterprise AI demand, grew 63% to just over $20 billion for the first time, and the company’s Cloud backlog nearly doubled quarter on quarter to over $460 billion.

For Berkshire, the investment is a bet on Alphabet’s ability to convert that backlog into revenue at scale. The $80 billion raise is unusual for a company of Alphabet’s profitability. It is, in effect, the market’s answer to a question Berkshire has been asking for a year: is Alphabet going to spend its way into the next decade of AI compute, or is it going to be outbuilt by Microsoft, Amazon, and the well-funded independents? Alphabet has decided to spend.

Sundar Pichai, Alphabet’s chief executive, told investors on the Q1 call that the company’s custom TPUs, Axion CPUs, and the latest NVIDIA GPUs “continue to form the industry’s widest variety of compute options,” per Pichai’s Q1 2026 remarks on cloud and AI momentum on Alphabet’s investor blog. Alphabet also introduced its eighth-generation TPUs at Cloud Next, with Pichai saying the new training chip offers three times the processing power of the prior Ironwood generation.

Cloud, Search, and Waymo: The Three Engines Powering the Compounding

Alphabet’s bull case rests on three business lines, each at a different point on the growth curve. Cloud is the youngest and fastest. Search is the oldest and most profitable. Waymo is the smallest and most unpredictable.

Cloud did $20.03 billion in revenue in the first quarter, ahead of the $18.4 billion consensus estimate, with the $460 billion backlog signalling that demand is running ahead of supply. Pichai said on the call that revenue from products built on Alphabet’s generative AI models grew nearly 800% year over year inside Cloud, and that the number of Gemini Enterprise paid monthly active users grew 40% quarter over quarter. Berkshire is not buying an aging search monopoly, in other words. It is buying a Cloud franchise whose growth rate has reaccelerated for three straight quarters.

Search is still the cash machine. Revenue from Search & Other Advertising grew 19% in the first quarter, with Pichai saying queries are “at an all-time high” and that AI Overviews and AI Mode are driving overall Search growth. Alphabet’s share of the global search market remains around 90%, according to a recent CNBC report, even after a federal court ruled that Google holds an illegal search monopoly and barred the company from exclusive distribution deals.

Waymo, Alphabet’s autonomous-vehicle unit, hit 500,000 fully autonomous rides per week in the first quarter, doubling in less than a year, and now operates in 11 major US cities after launching in Nashville in the spring. YouTube, the third leg, continues to compound quietly: more than 200 million hours of YouTube content are watched daily in US living rooms, and the number of paid subscriptions across Alphabet’s consumer services has reached 350 million.

• $20.03 billion in Q1 2026 Google Cloud revenue (up 63% year over year)
• $460 billion Cloud backlog (nearly doubled quarter on quarter)
• 19% growth in Q1 Search & Other Advertising revenue
• 500,000 fully autonomous Waymo rides per week
• $366.46 Alphabet closing share price on July 6, 2026

The Buffett Contradiction

For six decades, Buffett treated technology stocks as a class he did not understand well enough to value. The framing carried through to the Apple position, which Buffett defended for years by calling it a consumer-products company rather than a technology one. Alphabet has always been harder to recategorize. Its businesses are pure technology, and Berkshire’s move into the name is the first time in the conglomerate’s history that a CEO has committed a meaningful share of the equity book to a Big Tech platform without a Buffett-style consumer-products wrapper.

Buffett himself acknowledged the gap in a 2017 CNBC interview, saying GEICO had been an early heavy user of Google’s search ads and that he “should have had some insight” into the company’s profit potential. The AI build-out now underway at Alphabet is, in a sense, the asset Buffett told himself he couldn’t underwrite. Abel has decided he can.

Greg did this faster than I could have done it, smoother than I could have done it, and I never talked to the CEO. He has launched.

That is Buffett, on CNBC’s Squawk Box on June 1, the morning of the Alphabet deal, praising Abel for the Taylor Morrison acquisition. Buffett’s son Howard remains Berkshire’s non-executive chairman, and Buffett remains the largest shareholder. Abel has been running Berkshire’s non-insurance businesses since 2018, joined the board that year, and took over as CEO at the start of 2026 after Buffett stepped down at the end of 2025, per Greg Abel’s path from MidAmerican Energy to Berkshire CEO at Investopedia. The Alphabet bet is the first deal of the Abel era that carries no Buffett fingerprints on the investment thesis itself.

What Could Break the Thesis

The bull case is well-rehearsed. The bear case lives in four places.

• Antitrust. A federal judge ruled in 2025 that Google holds an illegal monopoly in online search, and Alphabet is now barred from exclusive distribution deals. A pending DOJ appeal is looking at structural remedies that could include a forced divestiture of parts of the search business.
• AI competition. Microsoft, Amazon, Meta, and a fleet of well-funded model labs are all building AI infrastructure at the same time. Alphabet’s first-mover advantage in TPUs is real but not durable.
• Capital intensity. Alphabet has guided to roughly $175 billion in AI-related capital expenditure this year, which is why the $80 billion equity raise exists at all. A misread on AI demand would leave the balance sheet overbuilt.
• Valuation. Alphabet trades at a 27.2 trailing P/E with a market cap above $4.3 trillion, levels that price in years of compounding. A slower-than-expected ramp in Cloud or Waymo would compress the multiple quickly.

None of those risks is new, and none of them has stopped the stock from roughly doubling since Berkshire began building the position. The thesis Abel is funding is straightforward: Alphabet is the only US company with a top-tier AI model, a hyperscale cloud, the dominant search engine, and a real autonomous-vehicle business, and it sells at a multiple below most of the AI pure-plays it competes with. That is the bet. The rest is execution.
