Warren Buffett and the quiet bet inside Omaha: buying back Berkshire, one share at a time

On a workday morning in Omaha, Warren Buffett still shows up “five days a week, ” even after stepping down as CEO of Berkshire Hathaway at the end of 2025. The door he walks through may be the same, but the message coming out of Berkshire in early March 2026 is different: the most visible purchase tied to his name right now is Berkshire Hathaway shares—through a renewed company buyback.

What is the only stock Warren Buffett is clearly buying right now?

Berkshire Hathaway itself. The company submitted a regulatory filing to the U. S. Securities and Exchange Commission on March 4, 2026, disclosing it had begun repurchasing shares. Berkshire’s new CEO, Greg Abel, confirmed the stock buybacks in a television interview the same day. Another filing dated March 5, 2026, announced that about $225 million was spent buying Class A shares under Greg Abel.

The move lands with particular weight because it comes after a long stretch of restraint. Warren Buffett was described as a net seller of stocks for 13 consecutive quarters before he stepped down as CEO. And while Abel has not detailed what Buffett is working on day to day, the buyback provides a clear, documentable signal: when Berkshire turns its capital inward, it is making a statement about its own valuation and priorities.

How did Greg Abel and Warren Buffett decide to resume Berkshire buybacks?

Greg Abel said Warren Buffett was “100% on board” with resuming repurchases after what was described as a long hiatus. Abel said he “consulted with Warren relative to the value and the timing” of the buybacks. That consultation is not just personal preference; it is embedded in Berkshire’s governance. Berkshire’s stock repurchase program—adopted by the board of directors last year—stipulates that the CEO must consult with the Chairman of the Board, a role held by Buffett.

In other words, the decision carries both a procedural and a philosophical signature. Berkshire will only repurchase its shares when Abel and Buffett both believe the share price is below the stock’s intrinsic value from a conservative viewpoint. That standard matters because it frames repurchases not as a mechanical way to use cash, but as an investment choice that must compete with every other possible deployment of Berkshire’s capital.

It also helps explain why the buyback caught attention. Berkshire’s share price was described as higher than it was during much of the period when Buffett did not repurchase shares. The change, as described in the context around the decision, was not simply the number on the ticker—it was the environment around it, with oil prices soaring, the economy weakening, and inflation potentially resurging. In that mix, Abel and Buffett “obviously see Berkshire Hathaway as the best buying opportunity around. ”

Why do buybacks matter to shareholders—and what changes after the CEO transition?

The buyback is one of the first major capital-allocation signals of Abel’s tenure as CEO, but it is also explicitly presented as a continuation of an approach built over years. A corporate change in July 2018 gave Warren Buffett more freedom to authorize repurchases. Before mid-July 2018, Buffett and his then right-hand man Charlie Munger could only approve buybacks if Berkshire’s shares fell to or below 120% of book value; that threshold was never met, and no buybacks were completed under that older rule set.

After July 17, 2018, the board amended the rules. The updated framework allowed repurchases to continue without a ceiling or end date as long as Berkshire maintained at least $30 billion in combined cash, cash equivalents, and marketable securities, and as long as Buffett believed the shares were intrinsically cheap. Under that regime, Berkshire repurchased shares for 24 consecutive quarters from July 2018 through June 2024, before a 21-month pause ended with the March 2026 restart.

For investors, the human angle is not just that a famous financier still keeps a five-day routine. It is that the company’s internal discipline—board rules, consultation requirements, and the conservative intrinsic-value test—creates a paper trail of intent that outlasts any one title. The “mystery stock” that Buffett and Abel favored above all else was identified plainly: shares of Berkshire Hathaway. From 2018 onward, the capital devoted to that preference reached $78 billion in less than eight years, exceeding the amount described as spent buying Apple, Chevron, Bank of America, and Occidental Petroleum combined.

That scale turns the buyback into more than a market footnote. It is a statement about what Berkshire’s leadership sees when it looks at its own balance sheet, subsidiaries, and long-term prospects—and what it believes is mispriced by the market at a given moment.

What resources does Berkshire have to keep buying—and what does that signal?

The ability to repurchase shares depends on cash, and Berkshire has plenty. Berkshire’s cash, cash equivalents, and short-term investments totaled $373 billion at the end of 2025, with much of it in U. S. Treasuries. The company described that sum as exceeding the market capitalization of 477 companies in the S& P 500.

But the buyback story is also about what Berkshire would rather own. In his first letter to Berkshire Hathaway shareholders, Greg Abel wrote: “We will always aim for ownership of productive businesses over U. S. Treasuries. ” He also wrote that Berkshire’s top capital allocation priority is to “invest in businesses that we thoroughly understand, with durable advantages and long-term economic prospects. ” The renewed repurchase program connects that philosophy to a concrete action: when leadership believes Berkshire itself meets those standards at an attractive price, it can choose to buy more of it.

For a company that has been active in markets and publicly associated with long-term investing, the March 2026 repurchase restart reads like a measured response to uncertainty—oil prices soaring, a weakening economy, and the risk of resurgent inflation—rather than an attempt to chase momentum. It is also a reminder that even after a CEO handoff, the consultative structure keeps Warren Buffett directly involved in decisions that have lasting consequences for shareholders.
