The quarter reads like a high-conviction Buffett snapshot just as Greg Abel steps into the CEO role. Berkshire’s Q4 2025 filing still looks like a Buffett portfolio Berkshire Hathaway finished 2025Q4 with $274.16B in reported 13F assets, 110 disclosed holdings, and an 85.75 WhaleScore — the highest score in the current filer universe. That combination matters because Berkshire is not winning on breadth. It is winning on concentration, durability, and a portfolio structure that still revolves around a handful of giant equity convictions tied to Warren Buffett’s capital-allocation framework. The timing matters too. Berkshire’s board said in May 2025 that Greg Abel would become President and CEO on January 1, 2026, and Buffett wrote in his November 2025 Thanksgiving message that Abel would become “the boss at yearend.” So this quarter-end snapshot reads like a bridge between Buffett’s long-running public-equity playbook and Berkshire’s next operating chapter. The headline signal: scale rose, holdings count fell Berkshire’s 13F value rose from $267.33B in 2025Q3 to $274.16B in 2025Q4, while the number of reported positions fell from 115 to 110. That is a classic Berkshire tell: more dollars concentrated into fewer disclosed lines. The result is a portfolio that looks more selective, not more diversified.

On the company’s 2025 annual report page and in the 2025 shareholder letter, management emphasized that equity investments remain concentrated in a small number of businesses Berkshire expects to compound over decades. The Q4 2025 13F looks exactly like that. Apple and American Express still anchor the book The top of Berkshire’s disclosed equity book remains dominated by a small set of names retail investors instantly recognize: Apple, American Express, Bank of America, Coca-Cola, and Chevron. After that come high-quality cash generators such as Moody’s, Occidental Petroleum, Kraft Heinz, and Alphabet.

Berkshire’s biggest weights are still businesses with established brands, repeat-purchase behavior, or durable financial economics. That also fits the company’s long-stated preference for understandable businesses and disciplined capital allocation, a theme Buffett repeated for years and that the company reiterated again around the December 2025 leadership appointments. Why the WhaleScore matters more here than for most mega-filers A high WhaleScore can mean very different things across the filer universe. For an ETF-heavy custodian, it can reflect sheer size without much thesis density. For Berkshire, the score carries more analytical weight because the 13F is comparatively compact. The filing on Stock Titan and the underlying SEC Form 13F show just 110 entries and 14 included managers. Berkshire’s scale is enormous, but its disclosed equity book is still unusually legible for a filer this large. That is why the 85.75 WhaleScore stands out. Berkshire is not spreading $274.16B across thousands of token positions. It is expressing conviction through a manageable list of holdings, with the top of the book doing most of the work. For readers tracking smart-money signals, that is exactly the kind of portfolio where concentration is the message. Context outside the 13F: the filing is only part of Berkshire’s capital story Investors should also avoid reading Berkshire’s 13F as the whole enterprise. The company’s 2025 annual report, 2025 10-K, and 2025 shareholder letter make clear that Berkshire remains a sprawling operating company with insurance float, wholly owned subsidiaries, and major non-13F assets. The reported public-equity portfolio is crucial, but it is only one layer of the broader capital-allocation machine. That distinction matters especially in a handoff year. Abel inherits not only a stock portfolio but an allocation system: large operating cash generation, decentralized business ownership, and a willingness to hold concentrated equity stakes for long periods. The Q4 2025 13F is useful precisely because it shows that the public-equity sleeve still follows that playbook. What retail investors should take away The portfolio is getting tighter, not broader. Berkshire added value in Q4 while trimming the number of holdings. The biggest positions still define the thesis. Apple, American Express, Bank of America, Coca-Cola, and Chevron remain the center of gravity. The WhaleScore is earned through conviction. Berkshire’s top ranking is more meaningful because the disclosed portfolio is concentrated and interpretable. The leadership transition does not yet look like a style break. Public disclosures around Greg Abel’s promotion point to continuity rather than a reset.

Because Berkshire combines enormous scale with a relatively compact, high-conviction 13F portfolio. A top WhaleScore means more when the public-equity book is concentrated and the largest holdings clearly drive the thesis. ### What were Berkshire Hathaway’s largest disclosed holdings in 2025Q4? The five largest disclosed positions were Apple, American Express, Bank of America, Coca-Cola, and Chevron. Together they occupied most of the top tier of Berkshire’s reported public-equity portfolio. ### Did Berkshire Hathaway’s 13F get bigger or smaller in Q4 2025? The reported 13F AUM increased to $274.16B from $267.33B in 2025Q3, while the number of disclosed holdings fell to 110 from 115. That combination suggests greater concentration rather than broader diversification. ### Why does the Buffett-to-Abel transition matter for this filing? Berkshire announced in May 2025 that Greg Abel would become President and CEO on January 1, 2026, and Buffett reiterated the transition in November 2025. That makes the Q4 2025 13F a useful bridge between Buffett’s long-running portfolio style and Berkshire’s next management chapter. ### Does Berkshire’s 13F show the whole company? No. The 13F captures Berkshire’s reportable public-equity holdings, but not the full operating-company ecosystem, all cash resources, insurance float, or wholly owned subsidiaries discussed in Berkshire’s annual report and 10-K. --- Source: 13F Insight — https://13finsight.com/research/berkshire-hathaway-q4-2025-highest-whalescore-buffett-handoff Author: Marcus Chen — https://13finsight.com/authors/marcus-chen Last updated: 2026-04-14T20:13:30.463Z
