Berkshire Hathaway discloses a $2.65 billion Delta Air Lines stake—and a wider Q1 portfolio reset

Berkshire Hathaway disclosed a $2.65 billion fresh position in Delta Air Lines on May 15, 2026, alongside a grab-bag of other first-quarter trades that together read like a deliberate hand on the tiller of the conglomerate's giant public-equity book (reported). The headline stake—about 6.1% of Delta, or roughly 39.8 million shares—arrives six years after Berkshire famously liquidated large airline bets at the start of the COVID-19 shock, when Warren Buffett told shareholders the "world had changed" for carriers (reported).

Markets treated the disclosure as more than trivia: Delta shares were quoted up about 3.3% after hours in early coverage tied to the filing, a reaction that often reflects investors pricing a quality stamp from an owner known for patience—and for walking away when economics sour (reported). Berkshire also reported a small Macy's position on the order of three million shares worth about $55 million, with that stock likewise moving sharply after hours (reported).

What the filing actually measures—and what it omits

The snapshot covers U.S.-listed equities held as of March 31 and therefore captures most, but not all, of a $288 billion equity stack described in contemporaneous reporting (reported). It does not automatically reveal which tickets were initiated by Greg Abel, who succeeded Buffett as chief executive, versus Ted Weschler, the other named portfolio manager—though commentary tied to prior disclosures has framed Abel as overseeing the vast majority of listed equities after Todd Combs left for JPMorgan Chase in December 2025 (reported).

Readers should treat the table as a photograph, not a forecast: prices move, hedges may exist off-sheet, and subsidiaries can hold positions that do not surface in the headline 13F window. Still, for Delta, the photograph is dramatic because it reverses a 2020 exit that had become a symbol of Berkshire's willingness to eat crow when facts change.

The Delta round-trip in one paragraph of industrial logic

Airlines are cyclical, capital-intensive, and exposed to fuel, labor, and geopolitics—all of which featured in filing-week commentary noting higher energy costs tied to Middle East disruptions (reported). Berkshire once held about 11% of Delta before the pandemic purge alongside stakes in American, Southwest, and United (reported). Returning now suggests the parent company sees a different balance of free cash flow, network quality, and balance-sheet resilience than it did when travel collapsed.

Whether that judgment ages well depends on recession timing, corporate travel budgets, and capacity discipline across the U.S. oligopoly structure that survived consolidation. Delta is frequently described by analysts as among the better-run large carriers—a qualitative claim the filing cannot prove, but one that helps explain why Berkshire might anchor on a single name rather than replicating the old four-carrier basket.

The rest of the book: exits, trims, and a bigger bet on Alphabet

Beyond Delta and Macy's, the same disclosure narrative summarized large rotations: Berkshire exited multibillion-dollar stakes in Visa and Mastercard, sold UnitedHealth and Amazon, and also stepped away from names including Domino's, Aon, and Pool—each a different micro-story about underwriting standards, fee economics, or consumer durability (reported). Chevron remained a top-five holding even after a roughly 35% share sale, a trim that arrived in a quarter when oil equities rallied sharply (reported).

On the buy side, reporting on the filing highlighted a more than tripling of Alphabet exposure to about $16.6 billion, making the Google parent one of Berkshire's largest common-stock lines, and a more than doubling of the New York Times stake to about 9.4% of that company (reported). Across the quarter, disclosures attributed to the filing summarized roughly $15.94 billion of purchases against about $24.09 billion of sales—evidence of active recycling rather than passive drift (reported).

Why this matters outside the Omaha fan club

Berkshire cash flows feed insurance, rails, utilities, and an eclectic operating portfolio; its listed equities book is therefore both a macro sentiment gauge and a liquidity buffer. When the parent sells tens of billions while buying tens of billions, asset managers and risk committees re-read sector skews—especially when the trades coincide with a leadership transition quarter for the parent itself.

For competitors, Delta's cost of equity can move when a famously long-horizon holder appears on the cap table; for regulators, the snapshot is another data point in ongoing debates about concentration and payments economics, even though Berkshire is not a bank holding company in the narrow sense. For ordinary readers, the lesson is simpler: the 2020 airline mea culpa was never a religious vow—it was a price-and-risk judgment that, on updated numbers, may now read differently.

NewsTenet will update this file if Berkshire files amended figures, if Delta issues material guidance that reframes cash generation, or if executives clarify attribution of trades across portfolio managers—until then, treat share counts and market values as March 31 artifacts, not live marks.
