Warren Buffett Remains Berkshire's Largest Individual Shareholder, With Forbes Pegging His Personal Fortune at About $149 Billion as of Mid-November. Here's Why Record Buybacks Are Quietly Growing His Stake Further.
Warren Buffett's net worth stands at $149 billion, representing nearly 12% of Berkshire Hathaway's $1.3 trillion market capitalization. CEO Greg Abel oversaw record $9.6 billion in share buybacks during Q3 2026, more than double Q2's total, which increases Buffett's ownership stake. However, Berkshire's massive $352 billion cash pile remains a drag on intrinsic value growth, as the company awaits high-return investment opportunities.
