Berkshire Hathaway's new CEO isn't making a quiet entrance when it comes to portfolio moves.
Berkshire's Q1 13F filing revealed many large shifts in its portfolio, with a new leader at the helm.
Alphabet and New York Times were winners, while Amazon and two payment giants lost their seats at the table.
It only takes one look at Berkshire Hathaway’s (NYSE: BRK.B) latest 13F filing to know that someone new is in charge. Warren Buffett retired as CEO at the end of 2025, and Greg Abel succeeded him. Saying that Abel turned over Berkshire’s portfolio in Q1 2026 may be an understatement.
In reality, “consolidated” may be a better fit. In Q1, Berkshire completely sold out of over 15 positions and added just a few new ones. Overall, the number of total holdings fell from 42 to 29, creating a significantly more focused portfolio. These are the biggest moves from Berkshire Hathaway's Q1 2026 13F filing.
Behemoths Go to Zero: Berkshire Exits Several Mega-Caps
Notably, the world’s two largest players in the payments industry lost their spot in Berkshire’s portfolio. Visa (NYSE: V) and Mastercard (NYSE: MA), each of which Berkshire previously had +$2 billion positions in, saw their shares held fall to zero. This comes at a time when fears around how agentic AI commerce could affect traditional payment platforms have hurt both stocks.
Still, it is difficult to say that Berkshire decided to sell Visa and Mastercard based on this, given Berkshire’s very low exposure to the AI investment theme. Further pushing back on this idea is the fact that the position in American Express (NYSE: AXP) remains unchanged.
UnitedHealth Group (NYSE: UNH), the world’s largest health insurance company, also went to zero. This is somewhat odd, as Berkshire made headlines by investing in the company just three quarters ago. It is completely possible that Berkshire exited this position at a loss, with UNH shares down 11% from the end of Q2 2025 to the end of Q1 2026. Given the quick sale, it is interesting to consider whether Abel disagreed with the initial investment.
The other most notable sale was clear: Amazon.com (NASDAQ: AMZN). This seems to be an extension of what happened in the previous quarter, as Berkshire likely sees another Magnificent Seven firm as better positioned in the AI race. In Q4 2025, Berkshire drastically decreased its Amazon position by 77%, while holding its large position in Alphabet (NASDAQ: GOOGL). This quarter, Berkshire’s Amazon position went away, and Alphabet got much, much bigger.
Other notable exits included Domino’s Pizza (NASDAQ: DPZ), Pool (NASDAQ: POOL), and Charter Communications (NASDAQ: CHTR). Additionally, Berkshire dropped its stake in Mexican beer maker Constellation Brands (NYSE: STZ) by 95%.
Berkshire Doubles Down on Alphabet, New York Times
The shift in Berkshire's Alphabet position is the biggest story from a buying standpoint. Notably, Berkshire increased its position in Alphabet’s Class A shares (ticker symbol GOOGL) by 204%. Along with appreciation, this moved the value of the position up from around $5.6 billion at the end of Q4 to $15.6 billion at the end of Q1. Berkshire also didn’t stop there, buying $1.03 billion worth of Alphabet’s Class C shares (ticker symbol GOOG).
Over the recent past, it seems to have clearly come to the belief that Alphabet is the most well-positioned public AI hyperscaler. In the past six months, Alphabet has been beating the brakes off of the rest of the other top hyperscalers when it comes to returns.
The stock is up over 40%, with Amazon’s less than 15% return a distant second. Overall, Berkshire’s position in Alphabet was approximately $16.6 billion at the end of Q1, its seventh-largest holding.
However, Alphabet wasn’t the only huge buy. Berkshire also massively upped its stake in the New York Times (NYSE: NYT). Its shares held increased by 199%, and the value of the position rose from $351 million to $1.27 billion. It’s uncertain if a Q1 event significantly increased Berkshire’s conviction in NYT, or if it just needed to redeploy capital from sold positions. Either way, Berkshire got rewarded for this move after NYT’s latest earnings report. The company posted results that were genuinely strong, leading shares to soar over 8% in response.
Delta and Macy’s Enter the Fold
In terms of new holdings, Berkshire initiated positions in Delta Air Lines (NYSE: DAL) and Macy's (NYSE: M). Its DAL position is moderately large, worth $2.65 billion. Meanwhile, Macy’s is its third smallest holding at $55 million.
Notably, Delta shares fell as much as 16% in Q1. This came weeks after the beginning of the conflict in Iran. Jet fuel prices more than doubled, putting significant pressure on Delta shares. It is likely that Berkshire saw this as an opportunity to take advantage of that shock.
Meanwhile, Macy’s fell as much as 23% in Q1. Compared to its all-time high market cap near $24.5 billion in 2015, the retailer has lost around 80% of its value.
However, the company’s last earnings report was solid, beating on sales, adjusted earnings per share, and issuing better-than-expected 2026 sales guidance.
Abel’s Tenure Kicks off With Fireworks
Overall, Q1 2026 was Berkshire’s most notable 13F filing in quite some time, and Greg Abel made his presence felt. It will be interesting to see if Q1 marks the reset of Berkshire’s portfolio, and future changes will go back to being relatively minimal. On the other hand, it could be that Abel is just getting started, and other large changes will follow.
Four leading AI models discuss this article
"Abel's quick portfolio overhaul risks higher volatility by abandoning Berkshire's diversification and long-hold discipline."
Berkshire's Q1 2026 13F under new CEO Greg Abel shows aggressive consolidation, cutting holdings from 42 to 29 by exiting Visa, Mastercard, Amazon, UnitedHealth, and others while more than tripling Alphabet to $16.6 billion and nearly quadrupling NYT. New stakes in Delta after its Iran-related fuel spike and tiny Macy's position suggest opportunistic value hunting. The rapid UNH exit just quarters after entry raises questions about conviction and timing. Relative to Berkshire's historic patience, this concentration could amplify equity volatility even if Alphabet's AI edge holds.
The sales may reflect routine liquidity needs or decisions finalized under Buffett rather than Abel's strategy, while Alphabet's gains simply extend prior overweighting without proving a new AI thesis.
"Abel's Q1 portfolio overhaul appears tactically sound but lacks the conviction-signaling clarity of Buffett's moves, making it impossible to distinguish between intelligent rebalancing and reactive chase-the-winners behavior."
Abel's Q1 moves read as portfolio reset, not conviction shift. Selling Visa/Mastercard at $2B+ each while keeping AmEx unchanged suggests tactical rebalancing, not AI-driven thesis. The 42→29 holdings compression is striking, but consolidation alone isn't bullish—it's defensive. Alphabet's 204% increase looks like chase-the-winner behavior post-40% rally, not prescient AI positioning. Delta at $2.65B during Iran-shock fuel spike and Macy's at $55M feel opportunistic bottom-fishing, not structural bets. NYT's 199% increase on $351M base is noise redeployment. Red flag: UNH exit at 11% loss three quarters after entry suggests either Buffett's conviction was weak or Abel disagreed sharply—neither inspiring.
Abel could be signaling genuine AI-era portfolio philosophy: hyperscaler concentration (Alphabet) over payment rails and healthcare middlemen. The 42→29 compression might reflect disciplined capital allocation, not panic. Alphabet's outperformance validates the trade, not invalidates it.
"Abel is transitioning Berkshire toward a tactical, high-conviction trading model that risks eroding the company's long-term competitive advantage of patience."
Greg Abel’s aggressive portfolio consolidation suggests a pivot from Buffett’s 'buy and hold' philosophy toward a more tactical, high-conviction approach. Exiting high-multiple payment processors like Visa and Mastercard while doubling down on Alphabet (GOOGL/GOOG) signals a bet on AI-driven search dominance over transaction-fee dependency. However, the entry into Delta (DAL) and Macy’s (M) is puzzling; these look like classic 'value traps' rather than strategic growth plays. If Abel is attempting to time macro-volatility—such as the oil-driven drop in airline stocks—he is abandoning the Berkshire mandate of buying durable competitive advantages in favor of cyclical trading, which introduces significant execution risk for a $1 trillion-plus entity.
Abel may simply be pruning the portfolio of assets that no longer fit the new, smaller capital allocation threshold, and the airline/retail buys could be opportunistic hedges against a consumer spending rebound that the broader market is currently mispricing.
"The Q1 2026 moves look like a tactical reshuffle—front-loading Alphabet and NYT while exiting cyclicals—rather than a durable shift in Berkshire's core, underscoring the danger of reading a single 13F as a new strategy."
Headline suggests a bold Abel-led pivot, but a Berkshire 13F is a quarter-end snapshot, not a thesis. The real Berkshire picture includes privately held businesses and a substantial cash cushion; the article omits Apple, Berkshire's core engine, and the rest of the non-public portfolio. The Alphabet and NYT purchases could be opportunistic reallocations or balance-sheet re-optimizations rather than a new AI-led growth regime. Exits from Visa, MA, UNH, and AMZN might reflect tax timing, liquidity needs, or tactical trimming, not a wholesale verdict on those franchises. In short: a tactical reset with potential upside risk if AI bets pay off, but little evidence of a durable strategic shift.
Apple remains Berkshire's silent anchor (not shown in this article); 13F misses private holdings and cash, so reading Abel's moves as a new AI pivot may be overstated. The moves could be routine rebalancing rather than conviction in Alphabet/NYT, and could reverse if macro or regulatory risk spikes.
"Abel's consolidation plus Alphabet overweight creates concentrated regulatory risk that the old diversified book had avoided."
Gemini flags Delta and Macy's as value traps but misses how these micro-positions could function as dry powder rather than core bets, freeing capital for the Alphabet concentration. The sharper risk is that pruning Visa and Mastercard while loading GOOGL hands regulators a clearer target for antitrust remedies, something Buffett's diversified approach historically diluted. If AI search dominance stalls, the compressed 29-stock book leaves fewer cushions than the old 42-name spread.
"Concentration risk from Alphabet matters less than the missing Apple context that makes this entire 13F analysis premature."
Grok's antitrust angle is sharp but overstates the regulatory exposure. Buffett's 42-stock portfolio didn't shield Berkshire from scrutiny—diversification is defensive camouflage, not legal protection. The real risk: if Alphabet faces forced divestitures (Search, YouTube), a $16.6B concentration becomes a liability. But ChatGPT's omission of Apple is the bigger tell—we're analyzing 13F noise while ignoring Berkshire's actual core engine. Without Apple's weighting and cash position, this 'pivot' narrative is built on incomplete data.
"Abel's pivot toward concentrated tech exposure risks eroding the valuation premium historically granted to Berkshire's defensive, diversified moat."
Claude is right about the 'noise' of 13Fs, but everyone is missing the signaling risk. By exiting UNH and AMZN while concentrating in GOOGL, Abel is signaling a departure from the 'moat' philosophy toward 'tech-beta' exposure. If Berkshire’s identity shifts from a defensive conglomerate to a high-conviction tech fund, the valuation multiple will inevitably contract. Investors pay a premium for Berkshire’s stability, not for Abel to compete with ARK or other concentrated growth managers.
"Alphabet concentration in Berkshire's 13F creates outsized risk if Alphabet's fundamentals or regulation turn adverse, making the pivot risky despite any 13F timing."
Grok exaggerates antitrust risk as Berkshire's near-term liability; the 13F snapshot is too coarse to declare a new AI thesis. The bigger risk is concentration: a 16.6B Alphabet stake in a 29-stock book doubles Berkshire's idiosyncratic risk to a single name. If Alphabet faces a regulatory drag or ad-market reversal, Berkshire’s beta risk climbs sharply, far more than any short-term 13F timing benefit.
The panel discusses Berkshire Hathaway's Q1 2026 13F under new CEO Greg Abel, with a consensus that the moves represent a portfolio reset rather than a shift in conviction. While some see opportunistic value hunting and a bet on AI-driven search dominance, others flag potential value traps and increased risk from concentration in Alphabet.
Potential upside if AI bets in Alphabet and NYT pay off.
Increased idiosyncratic risk due to high concentration in Alphabet, which could face regulatory drag or ad-market reversal.
