Warren Buffett retired as Berkshire Hathaway's CEO on Dec. 31, and Greg Abel has wasted no time making his presence felt.
Abel completely exited 16 of Berkshire's positions in the first quarter, including Amazon -- and profit-taking likely doesn't tell the full story.
Meanwhile, Abel made a pivotal artificial intelligence (AI) stock a top-five holding.
The trillion-dollar company that Warren Buffett helped build, Berkshire Hathaway (NYSE: BRKA)(NYSE: BRKB), entered uncharted territory in 2026. With the Oracle of Omaha retiring from the CEO role on Dec. 31, Berkshire has a new boss for the first time in well over half a century.
Buffett's successor, Greg Abel, hasn't wasted any time making his presence felt. During the first quarter, Abel exited 16 positions, including e-commerce kingpin, Amazon (NASDAQ: AMZN). At the same time, he more than tripled his company's stake in Google parent Alphabet (NASDAQ: GOOGL)(NASDAQ: GOOG), which has surged more than 15,500% since its initial public offering.

One of the more eye-popping first-quarter moves, as shown in Berkshire Hathaway's Form 13F, was Abel green-lighting the sale of all 2,276,000 shares of Amazon.
The argument can be made that this move was telegraphed. Buffett, in his final quarter as CEO, dumped 77% of Berkshire's stake in Amazon. Sales of that size almost always mean a holding is being given the heave-ho.
The most logical reason for Abel to send Amazon packing is to lock in sizable profits. Berkshire first acquired shares of Amazon in the first quarter of 2019. On a split-adjusted basis, Amazon stock rallied from roughly $80 to north of $200 over the last seven years.
But profit-taking probably isn't the full story.
Although Amazon's cloud infrastructure services platform, Amazon Web Services (AWS), is growing like a weed, and its online marketplace is as dominant as ever, Berkshire's new boss is a stickler for value. Amid a historically expensive stock market, Amazon's price-to-earnings (P/E) ratio of 32 stands out for all the wrong reasons.
Abel's willingness to sell a third of Berkshire's positions in the first quarter indicates his focus on value and his desire to concentrate his company's assets in his best ideas.
At the other end of the spectrum, Warren Buffett's successor made Alphabet a top-five holding. Berkshire's 13F shows 36,403,656 Class A shares (GOOGL) were bought, and a new position was opened by purchasing 3,585,215 Class C shares (GOOG).
Abel, like the Oracle of Omaha, has always favored businesses with sustainable moats. Alphabet has a virtual monopoly on internet search through Google. According to GlobalStats, Google has accounted for 89% to 93% of global internet search traffic over the trailing decade.

Alphabet's cloud infrastructure services platform, Google Cloud, is growing even faster than AWS. Integrating generative AI and large language model capabilities into Google Cloud lifted sales by 63% in the first quarter compared to the previous year. Alphabet is transforming into a cash cow and a pivotal AI player before our eyes.
But most of all, Alphabet has traditionally offered investors an intriguing value proposition. While Amazon remains historically inexpensive relative to its future cash flow, it's not a bargain based on the time-tested P/E ratio. Though Alphabet isn't exactly a screaming bargain as of this writing in late May, its shares were trading at just 17 times forward-year earnings a year ago.

Four leading AI models discuss this article
"Abel is trading Buffett's diversified value discipline for concentrated mega-cap tech exposure at precisely the moment the article admits valuations are historically expensive."
The article frames Abel's moves as a clean philosophical pivot—dumping expensive AMZN, tripling down on GOOGL's 'virtual monopoly.' But this narrative glosses over timing risk and concentration danger. Yes, GOOGL trades at 17x forward earnings versus AMZN's 32x, but that valuation gap exists for reasons: AWS margins are structurally superior, AMZN's reinvestment optionality is higher, and GOOGL faces real regulatory headwinds the article doesn't mention. More concerning: tripling a position in any single stock—even a quality one—during a period of 'historically expensive' valuations (per the article itself) is aggressive. If rates spike or AI hype deflates, concentrated mega-cap tech exposure becomes a liability, not a feature.
Abel's move could simply reflect that Berkshire's AMZN position had become too large relative to new opportunities, and GOOGL's AI integration into Cloud (63% YoY growth) genuinely justifies re-rating—meaning the valuation gap is closing, not widening.
"Alphabet's regulatory risk to its core monopoly is materially underweighted relative to the AI growth narrative."
The article frames Abel's complete Amazon exit and tripling of Alphabet as decisive value hunting, highlighting the search monopoly and Google Cloud's 63% AI-driven growth. Yet 13F data only shows end-of-quarter holdings, not timing or intent, and Berkshire's prior 77% Amazon trim began under Buffett. Alphabet trades at 17x forward earnings but faces unresolved DOJ antitrust remedies that could erode its 90%+ search share within 2-3 years. The piece also omits that Amazon's AWS still leads cloud margins while Alphabet's valuation has already rerated higher on AI enthusiasm.
Antitrust remedies historically take years to implement and rarely destroy cash-flow dominance, as seen with prior Microsoft cases, so Alphabet's moat could remain intact long enough to justify the stake increase.
"Abel’s rotation into Alphabet reflects a defensive preference for lower-multiple tech rather than a fundamental shift in Berkshire’s long-term investment strategy."
The market is over-interpreting Greg Abel's portfolio churn as a fundamental shift in Berkshire's philosophy. While the move from Amazon to Alphabet is framed as a pivot toward 'value,' it’s more likely a tactical reallocation of capital toward a lower-multiple AI play. Amazon’s 32x P/E is a premium for its logistics moat and AWS dominance, whereas Google’s 17x forward P/E (as cited) implies the market is pricing in significant regulatory risk or search-share erosion from generative AI. Abel isn't necessarily abandoning growth; he is hunting for a margin of safety in a tech sector that has become increasingly speculative. This isn't a 'new era' for Berkshire; it's classic capital allocation under pressure.
The move could signal that Abel views Google’s search monopoly as structurally impaired by AI-driven search alternatives, making the 'value' entry point a classic value trap.
"Abel’s reshuffle signals Berkshire tilting toward Alphabet as an AI-moat bet, but one quarter isn’t durable conviction and upside hinges on Alphabet sustaining AI monetization amid regulatory and ad-market risks."
Today's takeaway: Abel’s Q1 2026 moves show Berkshire shedding a large Amazon exposure and materially boosting Alphabet, a clear tilt toward AI-enabled moats. Selling all 2,276,000 AMZN shares while tripling Alphabet (36,403,656 Class A; 3,585,215 Class C) signals a value/momentum shift: Amazon’s high multiple and consumer exposure vs Alphabet’s ad/Cloud AI upside. Alphabet’s cloud growth 63% YoY and Google's dominant ad position support the bull case; but Berkshire’s 13F is a snapshot, not a thesis. The biggest risks are regulatory headwinds for Alphabet and potential AI-ad monetization softness, plus AWS remains a durable earnings driver for Amazon. This looks like a quarter-level reweighting, not a durable conviction.
The move could be window-dressing or tax harvesting; a single quarter's data point is not proof of a long-term pivot, and Amazon’s cash flows could still be central to Berkshire’s risk-adjusted return.
"Search antitrust risk is priced into Alphabet's 17x multiple, but Cloud's growth optionality may not be."
ChatGPT flags the 13F as a snapshot, but nobody's quantified what 'tripling' actually means for Berkshire's portfolio weight. If Alphabet went from 1.5% to 4.5% of holdings, that's material conviction; if 0.8% to 2.4%, it's noise. Claude and Grok both cite regulatory risk to Alphabet's search moat, but neither addresses whether a DOJ breakup of search actually impairs Google Cloud's 63% growth trajectory—those are separable businesses. That's the real bull case Abel may be seeing.
"Regulatory remedies on search could impair Cloud's data moat and delay margin expansion needed to justify the stake increase."
Claude separates search remedies from Cloud's 63% trajectory, but that ignores potential spillover: DOJ-mandated data sharing or default changes could directly constrain the ad and AI datasets that power Google Cloud's growth. If remedies erode data advantages, Cloud margins may stay compressed longer than the 17x multiple implies, turning Abel's reallocation into a value trap rather than a clean AI bet.
"Regulatory data-sharing mandates would fundamentally break the AI-driven growth trajectory of Google Cloud, rendering the current valuation a value trap."
Grok, your focus on data-sharing mandates is the critical missing link. If the DOJ forces Google to unbundle search data, the 'Cloud' growth isn't just a separate business; it loses the proprietary AI training flywheel that justifies the premium. Abel is betting on a moat that regulators are actively trying to drain. If the data advantage is legally compromised, the 17x multiple isn't a bargain—it's a reflection of a structural impairment to the core AI product.
"Data-sharing remedies are unlikely to kill Alphabet's AI moat; monetization will endure via Cloud APIs and Workspace, and the bull case rests on product-led AI demand rather than data exclusivity."
Grok, your data-sharing fear is real but not a universal moat-killer. Remedies are unlikely to erase Alphabet’s Cloud value chain; even with data constraints, Google can monetize AI through Cloud APIs, Vertex-like tools, and Workspace integrations, sustaining revenue growth. The bigger risk remains monetization cadence and enterprise adoption, not only remedies or 63% YoY growth. If data access is mandated, margins may compress, but the bull case rests on product-led AI demand, not data exclusivity alone.
