Berkshire Hathaway Reports $299.3 Billion Portfolio in Q3 2026, Apple Remains Largest Position
Under Warren Buffett's leadership, Berkshire Hathaway reported a portfolio of $299.3 billion as of September 30, 2026, with 22% invested in Apple. The top 10 holdings account for nearly 99% of the total value, with American Express and Alphabet in second and third places.
Berkshire Hathaway, led by legendary investor Warren Buffett, reported a marketable portfolio of $299.3 billion for Q3 2026, according to the 13F-HR filing published on August 14, 2026, on the SEC website.
Warren Buffett employs an investment strategy focused on intrinsic value, business quality, and long-term holding. His approach emphasizes companies with sustainable competitive advantages, strong cash flow histories, and management capable of generating returns exceeding the cost of capital. Historically, the fund has outperformed benchmark indices over decades, confirming the validity of its model centered on patience and discipline.
The sectors most represented in the portfolio reflect this orientation: consumer technology, financial services, consumer staples, energy, and insurance. This sector diversification helps mitigate risks while capitalizing on businesses with strong cash-flow generation capabilities.
Major New Positions and Strengths
The Q3 2026 13F filing indicates no notable new positions or significant increases compared to previous filings. The portfolio consists of 26 holdings, with the top 10 aggregating $272.6 billion (approximately 91% of the total). Apple Inc. remains the largest holding at $65.95 billion (22.0% of the portfolio), followed by American Express Co. at $51.28 billion (17.1%), and Alphabet Inc. at $37.76 billion (12.6%). The other top-10 holdingsâCoca-Cola, Bank of America, Chevron, Occidental Petroleum, Chubb Limited, Moody's Corp., and Kraft Heinzâeach represent between 2.6% and 10.9% of the portfolio.
These investments span industries where Buffett has traditionally found value opportunities: technology giants Apple and Alphabet benefit from recurring cash flows through their digital ecosystems, while financial institutions like American Express and Bank of America leverage high-margin payment networks and banking services. Consumer staples such as Coca-Cola and Kraft Heinz are recognized for their pricing power and resilience during economic slowdowns. Finally, energy sector positions (Chevron, Occidental) and insurance (Chubb) offer exposure to stable revenues and long-term premiums.
Reductions and Exits â What Buffett/Management is Exiting
According to the August 14, 2026, 13F-HR filing, no position reductions or full exits are explicitly noted. The document only lists holdings as of the quarter's end, without mentioning recent divestitures. Thus, the reported portfolio represents all positions maintained by Berkshire Hathaway at the end of Q3 2026.
Limitations of the 13F: What This Filing DOESN'T Say
The 13F form, mandatory for managers with over $100 billion in assets under management, has several limitations. Information is published 45 days after the quarter's end, meaning post-closure moves aren't reflected. The filing only covers long equity positions in listed U.S. companies; short sales, options, unlisted securities, and non-U.S. assets are excluded. Consequently, the overview provided by the 13F doesn't capture the full range of coverage strategies or alternative investments the fund may employ.
