Warren Buffett and Berkshire Hathaway (NYSE: BRK.A) (NYSE: BRK.B) have been practically synonymous for decades. I doubt that will change with the legendary investor stepping down as Berkshire's CEO at the end of this year.

The good news for Buffett fans is that he isn't leaving completely. Berkshire's board of directors wants him to remain chairman after he turns the CEO position over to Greg Abel. Buffett will also still own a big chunk of the company. But who owns the most Berkshire Hathaway shares besides Buffett?

Following the money

As of March 5, 2025, Buffett owned 206,359 Berkshire Hathaway Class A shares -- 37.9% of the total outstanding shares. No one else comes close to that level. This gives Buffett 30.4% voting power over the company's Class A and Class B shares.

FMR, LLC comes in a distant second to Buffett. The parent company of Fidelity Investments owns 33,517 of Berkshire's Class A shares, representing 6.17% of the total outstanding shares. Investment firm First Manhattan is another holder of Berkshire Hathaway Class A shares, with 2.73% of outstanding shares.

Because of the exorbitant price tag of Berkshire's Class A shares (close to $779,000 at the time of this writing), they aren't as widely held as the conglomerate's lower-cost Class B shares. Buffett owns only 951 Class B shares. The largest holder is Vanguard Group, which owns more than 148 million Berkshire Class B shares, representing 11% of the total outstanding shares.

Other fund managers also hold major stakes in Berkshire Hathaway Class B shares. BlackRock owns nearly 111.6 million Class B shares, roughly 8.3% of the total outstanding shares. State Street Corporation ranks high on the list as well, with nearly 71.7 million Class B shares making up 5.35% of the total.
