What Is Warren Buffett Buying? A Deep Dive Into Berkshire's 2025 Portfolio Moves

Warren Buffett’s investment strategy in 2025 reveals a fascinating picture when you look past the headlines about stock sales. While Berkshire Hathaway became a net seller in the first half of the year, that story only captures part of the narrative—and arguably the less interesting part. The conglomerate actually engaged in substantial buying activity, which tells us much more about where Buffett sees opportunity in today’s market.

The reason Berkshire showed up as a net seller was primarily due to two major strategic exits: significant reductions in positions in Apple and Bank of America, designed to trim what had become outsized holdings. But strip away these two large dispositions, and you’ll find Warren Buffett and his investment team were remarkably active on the acquisition front, particularly during the second quarter.

Unveiling New Stakes: Fresh Stocks Entering Berkshire’s Portfolio

The second quarter of 2025 marked an acceleration in Berkshire’s buying appetite, with the company establishing six entirely new positions during the first half of the year. The shift was dramatic compared to the more cautious Q1 period.

Among the fresh acquisitions, UnitedHealth Group received the most significant capital allocation from Buffett’s team, with Berkshire accumulating 5,039,564 shares valued at approximately $1.57 billion as of mid-year. This healthcare play signaled confidence in the sector’s structural growth prospects. Simultaneously, industrial and housing-related stocks caught Buffett’s attention: Nucor (a steel producer) received 6.6 million shares worth $857 million, while homebuilders Lennar and D.R. Horton entered the portfolio with positions valued at $780 million and $191 million respectively.

The portfolio also expanded into advertising infrastructure through Lamar Advertising ($142 million) and security solutions via Allegion ($112 million). These diverse sector additions across healthcare, industrials, building materials, advertising, and security hardware suggest Buffett’s team was hunting for value across multiple market segments rather than concentrating bets in a single narrative.

Adding Fuel to Existing Holdings: Where Berkshire Doubled Down

While establishing new positions grabbed headlines, the real conviction plays often appear in how Buffett manages existing stakes. Here’s where the 2025 activity becomes particularly revealing about his market view.

Energy dominated the additions strategy. Chevron saw the most aggressive accumulation: Berkshire added 763,017 shares in Q1 and another 3,454,258 in Q2, bringing the total position to $17.5 billion. This wasn’t tentative buying—this was Warren Buffett methodically building exposure to crude oil supply dynamics amid evolving global energy landscapes.

Consumer discretionary names also attracted incremental deployment. Constellation Brands received substantial additions (6.4 million shares in Q1 plus 1.4 million in Q2), reflecting Buffett’s enduring preference for branded consumer products. Domino’s Pizza and Pool Corporation both saw tactical increases, suggesting the team believes these resilient consumer-focused businesses remain attractively priced.

Media holdings weren’t ignored either. Berkshire significantly augmented its SiriusXM position in Q1 with 2.3 million shares, signaling potential conviction in satellite radio’s moat. Other notable additions included boosting stakes in Heico and modest increases in Pool Corp throughout the first half.

What These Moves Reveal About Buffett’s Investment Thesis

It’s worth acknowledging the limitations of this analysis. We can’t always determine whether Buffett himself directed each transaction or if investment managers Ted Weschler or Todd Combs initiated the smaller acquisitions. We also lack precise timing information—did Berkshire accumulate these stakes during the April market dip, or during June’s rally to fresh records? Context matters enormously when evaluating whether a position acquired weeks apart actually reflects the same investment conviction.

That said, the collective pattern of buying activity illuminates Buffett’s current thinking about value. The concentration in energy names, the strategic adds to consumer franchise holdings, the healthcare bet through UnitedHealth—these choices point toward an investor seeking tangible assets and established business models rather than chasing growth narratives.

The 2025 portfolio activity offers a roadmap for investors interested in understanding where legendary capital deployment is hunting for opportunity. While blindly following any investor’s trades—even Buffett’s—carries obvious risks, using his documented buying behavior as a springboard for deeper research into these specific companies and sectors represents a time-tested investment approach.
