Following Warren Buffett's retirement as CEO on Dec. 31, Abel completely revamped Berkshire's $330 billion investment portfolio.
Berkshire's longtime No. 1 holding is relying on artificial intelligence (AI) integration to boost demand for its products.
Meanwhile, Abel piled into a virtual monopoly in the first quarter, whose high-margin sales are surging, courtesy of AI.
This isn't your grandparents' Berkshire Hathaway (NYSE: BRKA)(NYSE: BRKB) anymore! Following the retirement of billionaire Warren Buffett as CEO on Dec. 31, Berkshire has a new boss overseeing the company's day-to-day operations and $330 billion investment portfolio: Greg Abel.
The Oracle of Omaha's successor wasted no time overhauling Berkshire's portfolio during the first quarter. Notably, he completely exited a third (16) of the positions Buffett had overseen, and has concentrated over 28% of Berkshire Hathaway's portfolio into two artificial intelligence (AI) titans: Apple (NASDAQ: AAPL) and Google parent Alphabet (NASDAQ: GOOGL)(NASDAQ: GOOG).

Although Apple has been Berkshire's No. 1 investment holding by market value for years, Buffett spent his final two years in charge as a persistent seller of Apple shares. Despite Buffett shedding 75% of his company's Apple stake, it still accounts for close to 22% of invested assets.
The Oracle of Omaha always appreciated Apple for its consumer ties and its market-leading share repurchase program. While Buffett never had a firm understanding of Apple from a technological standpoint, he was well aware of the company's pricing power and consumers' loyalty to the brand.
Since initiating a buyback program in 2013, Apple has spent north of $853 billion to lower its outstanding share count by more than 44%. This has had an undeniably positive impact on its earnings per share.
Abel believes Apple can be a multidecade compounder in Berkshire's portfolio, with AI expected to play a key role. Apple's integration of AI solutions (Apple Intelligence) into its physical devices, coupled with ongoing updates to its voice assistant Siri, should bolster demand for iPhone, Mac, and iPad.
Perhaps the most eyebrow-raising move of Greg Abel's early tenure is his perceived conviction in Google parent Alphabet. During the March-ended quarter, Abel scooped up 36,403,656 additional Alphabet Class A shares (GOOGL) and opened a new position with 3,585,215 Alphabet Class C shares (GOOG). Collectively, this now ranks as a top-five position for Berkshire Hathaway, valued at $22 billion on May 29.
Alphabet certainly offers the sustainable moat that Berkshire's current and now-former boss appreciates. According to GlobalStats, Google has accounted for between 89% and 93% of monthly global internet search traffic over the trailing decade. With Alphabet also the parent of streaming platform YouTube, the second-most-visited site on the planet behind Google, it's easy to see why it has such incredible ad pricing power.
But Alphabet's long-term growth story centers on AI. Since integrating generative AI solutions and large language model capabilities into Google Cloud, sales growth for this considerably higher-margin segment has reaccelerated. During the first quarter, Google Cloud's sales jumped by 63% compared with the previous year.
Whereas Nvidia has been the face of the infrastructure side of the AI revolution, Alphabet has positioned itself as one of the premier companies in AI applications.
With 28% of Berkshire Hathaway's portfolio exposed to two AI titans, Abel has made it clear that tech stocks are firmly on the menu in the post-Buffett era.

Four leading AI models discuss this article
"Abel is concentrating Berkshire into the exact mega-cap tech positions that Buffett was exiting, at valuations that require near-perfect execution and no regulatory headwinds to justify holding 28% of a $330B portfolio in two stocks."
The article frames Abel's concentration into Apple (21.6%) and Alphabet (6.7%) as forward-thinking AI conviction, but this represents a dramatic shift toward mega-cap tech concentration—28% into two stocks. The real risk isn't whether AI matters; it's that Berkshire is now structurally vulnerable to a tech correction at precisely the moment when valuations are stretched. Apple trades at ~30x forward earnings; Alphabet at ~25x. Buffett's 75% Apple exit suggests he saw valuation risk the article doesn't acknowledge. Abel's Q1 buying into Alphabet after a 70%+ rally from 2023 lows looks like buying strength, not value.
If AI adoption accelerates faster than consensus expects and these companies maintain pricing power through regulatory scrutiny, a 5-10 year hold could compound at 15%+ annually—exactly the multidecade thesis Abel articulated. The article's silence on valuation risk could simply reflect that growth justifies current multiples.
"Abel's portfolio changes increase single-stock concentration risk without fundamentally transforming Berkshire into an AI growth vehicle."
Abel's first-quarter overhaul concentrates 28% of Berkshire's $330B equity book into Apple ($71.1B) and Alphabet ($22B), exiting 16 legacy positions. While Apple Intelligence and Google Cloud's 63% YoY growth are cited as catalysts, the moves largely extend Buffett-era Apple holdings and add Alphabet exposure to an already dominant search franchise. Concentration risk rises sharply versus diversified prior management, and both names trade at premiums reflecting AI narratives rather than traditional value metrics. Regulatory overhang on Alphabet and Apple's hardware-cycle dependence remain unaddressed.
The article underplays how Alphabet's cloud re-acceleration and Apple's installed base could deliver durable earnings growth that outweighs antitrust or cycle risks, validating the concentration.
"Abel’s portfolio concentration reflects a traditional search for high-moat, cash-generative monopolies rather than an aggressive, speculative pivot into AI growth."
The narrative that Greg Abel is 'pivoting' Berkshire toward tech-heavy AI growth is likely a misinterpretation of portfolio rebalancing. While the $22 billion stake in Alphabet is a notable departure from Buffett’s historical tech-aversion, it aligns with a 'wide-moat' value strategy rather than an AI speculative play. Google Cloud’s 63% growth is impressive, but the article conflates this with the core search business, which faces existential threats from LLM-driven search disintermediation. By concentrating 28% of the portfolio in AAPL and GOOGL, Abel is effectively betting on the long-term durability of these companies' cash flows, not necessarily an AI-driven earnings explosion. This is less a 'new era' and more a shift toward high-quality, cash-generative monopolies.
If the AI transition renders traditional search and hardware-centric revenue models obsolete, Berkshire’s massive concentration in these two legacy giants could lead to the most significant value destruction in the firm's history.
"Abel’s 28% concentration in two AI-driven megacaps risks Berkshire’s diversification, leaves the portfolio vulnerable to AI-cycle shifts, and faces valuation and regulatory headwinds that could impair durable returns."
The article paints Greg Abel as pivoting Berkshire Hathaway toward a bold AI-centric bet, with roughly 28% of invested assets in Apple and Alphabet. That signals a stark shift from Buffett’s diversified, insurance-flloat-centric approach to a concentrated, growth-oriented tech stance. Yet the gloss hides meaningful risks: AI is a hype cycle whose earnings durability is unproven; regulatory and antitrust risks loom over both Apple and Alphabet; tech-dominant portfolios can amplifiy drawdowns in cyclic tech selloffs; Berkshire’s other engines (float, energy, insurance) may suffer if rates or volumes disappoint; and valuations in these two behemoths are stretched versus historical earnings power.
Bull case: Apple and Alphabet are entrenched moats with durable cash flows and strategic AI leverage; Berkshire’s capital strength and buyback-friendly stance could amplify rewards. A 28% concentration might reflect conviction rather than risk, not unlike Buffett’s characteristic bets on big winners.
"Calling Alphabet a 'cash-generative monopoly' sidesteps whether that cash generation survives AI-driven search disruption—which is the actual thesis Abel is betting on, not proven."
Gemini's 'wide-moat value' framing masks the core tension: if search faces 'existential threats from LLM-driven disintermediation,' then Google isn't a durable moat—it's a legacy business in transition. Abel's $22B bet assumes the moat survives the disruption. That's not value investing; it's a binary bet on Google's ability to monetize AI search before disruption erodes margins. The article never addresses whether Abel is buying Google's past or its future.
"Berkshire's insurance float could face simultaneous pressure during a tech correction, amplifying risks from the concentrated holdings."
Claude highlights the binary bet on Alphabet surviving disruption, yet the panel overlooks how a concentrated tech portfolio interacts with Berkshire's insurance float. Should AI hype fade and trigger a market correction, simultaneous pressure on float from higher interest rates or lower premiums could constrain Berkshire's ability to support the equity book through buybacks, creating a double vulnerability not addressed in prior comments.
"Berkshire's massive cash pile negates the liquidity risk of a tech-concentrated portfolio during a market downturn."
Grok, you're missing the liquidity buffer. Berkshire holds $189B in cash and equivalents. Even if a tech correction hits, they aren't forced to liquidate these positions; they have the dry powder to double down. The risk isn't a 'double vulnerability'—it's the opportunity cost of holding cash while waiting for a dip that may never come. Abel isn't just betting on tech; he's betting that Berkshire's balance sheet allows him to outlast any regulatory or cyclical volatility.
"Dry powder alone cannot shield Berkshire from the risks of a concentrated AAPL/GOOGL bet that could compress Berkshire's float-driven gains and liquidity during a regime shift of valuations and AI-driven hype."
Gemini's cash buffer argument glosses over allocation frictions. Dry powder helps, but Berkshire's core equity engine is float and buybacks funded by underwriting results, not idle cash forever. Concentrating 28% in AAPL/GOOGL risks earnings volatility if AI hype cools, and may squeeze Berkshire's ability to deploy capital without scoping the risk to the insurance cycle. The risk isn't just a tech correction but a regime shift in valuation and liquidity effects on the float.
