Over six decades, Warren Buffett’s Berkshire Hathaway (BRK.A) has compounded at roughly 20% a year, trouncing the S&P 500 and reaching a market cap of three-quarters of a trillion as of July 2025. "Baby Berkshires:" Markel and Fairfax Lead the PackRichmond-based Markel Group (MKL) is perhaps the closest analog. Its $25 billion market cap, eclectic Markel Ventures portfolio, and annual “Markel Omaha Brunch” underscore the cultural homage. With a $4 billion market cap, the company offers plenty of runway, but financing costs for property deals make float harder to replicate, and real estate is cyclical. Among the imitators, even the best-positioned "Baby Berkshires" are operating with one-tenth—or less—of Berkshire’s float and have far shallower benches of operating companies.
