Warren Buffett, widely known as the Oracle of Omaha, is regarded as one of the greatest investors of all time. As chairman and CEO of Berkshire Hathaway, Buffett transformed a struggling textile business into one of the most powerful conglomerates in the world, with interests spanning insurance, railroads, utilities, manufacturing, consumer brands, and — most notably — publicly traded equities.
Buffett’s investing philosophy is built on patience, discipline, and conviction. Rather than chasing short-term market trends, he focuses on owning exceptional businesses with strong competitive advantages, durable earnings, and trustworthy management teams. Berkshire Hathaway’s equity portfolio remains one of the most closely watched in global markets, offering investors valuable insight into long-term capital allocation at the highest level.
Understanding 13F Filings and Data Sources
All portfolio data in this article is sourced directly from Berkshire Hathaway’s Q3 2025 13F filing, as compiled by WhaleWisdom, reflecting holdings as of September 30, 2025.
A 13F filing is a quarterly report that institutional investment managers with more than $100 million in U.S. equity assets must submit to the U.S. Securities and Exchange Commission (SEC). These filings disclose all U.S.-listed equity positions held at quarter-end, providing transparency into how major investors allocate capital.
It’s important to understand the limitations of 13F data:
-
It excludes international stocks, bonds, cash, and derivatives
-
It reflects a historical snapshot, not real-time trading
-
Filings are released weeks after quarter-end
Despite these constraints, 13Fs remain one of the most reliable tools for tracking the long-term strategies of elite investors like Warren Buffett.
Q3 2025 Portfolio Update (As of September 30, 2025)
What Changed This Quarter? (TL;DR)

Alphabet (GOOGL) was the largest addition, increasing by +1.62% of the portfolio.
-
Apple (AAPL) remained Berkshire’s largest holding at 22.69%, reinforcing its role as the portfolio’s core anchor.
