Abel spent 5.5 times last year's first-half equity budget before Buffett gave up the chair
Berkshire put $39.4bn into equities in the first half of 2026 against $7.1bn a year earlier. On September 18 the chairmanship passed to Howard Buffett, whose remit his father defined as guarding the culture.

What happened
- Warren Buffett, 96, stepped down as Berkshire Hathaway chairman on September 18, effective immediately, after more than six decades in the role, and stays on the board as chairman emeritus.
- His son Howard G. Buffett, a Berkshire director for 33 years, took the chairmanship, completing a transition that began when Greg Abel became chief executive on January 1.
- Berkshire spent $39.4bn on equity purchases in the first half of 2026, more than five times the $7.1bn it deployed in the same period a year earlier.
Compiled by The InvestorSomething wrong?How this is made
Why it matters
- constraint Cultural stewardship produces no quarterly number, so between now and the first deal that goes wrong, shareholders have nothing from Howard Buffett's side of the structure to check Abel's spending against.
- exposure With $37.8bn sitting in Alphabet at midyear, the first mark-to-market verdict on Berkshire's new management comes from another company's AI capital spending.
- precedent A family chairman named culture custodian alongside a serving lead independent director gives other founder-controlled boards a template to cite when they split the top job in two.
- decision Berkshire's board now has to work out in practice whether the culture role can block a capital allocation or only comment on it after the money has gone out.
A $10bn commitment to support Alphabet's AI investments is about a quarter of the $39.4bn Berkshire put into equity purchases in the first half of 2026, and Fortune called AI a new area for the conglomerate [14][19][13]. The holding was worth $37.8bn at midyear, third-largest in the book, after Abel added 48.1 million shares [14]. The other two items Fortune names look like older Berkshire: $6.8bn for the homebuilder Taylor Morrison, which the publication described as a typical value bet in the Buffett mold, and $4.5bn of buybacks after more than a year of none [15][16]. Those three come to $21.3bn [21].
The year-on-year change in equity buying is $32.3bn, against $7.1bn absorbed in the same half of 2025, or 5.5 times the pace [13][18].
Buffett drew the division of labour himself. "Greg runs the company; Howard will guard its culture and values," he wrote, calling culture and values "worth more than anything on our balance sheet" [8][9]. Abel said Buffett's impact on Berkshire was "without parallel in the history of American business" and that the culture he built "will remain at the heart of Berkshire, and Howard will be their guardian" [10][11]. Susan Decker continues as lead independent director [12]. Fortune did not report what formal powers the chairmanship carries.
The handover came eight and a half months after Abel became CEO on January 1 [22][4]. Berkshire called it part of a "long-standing succession plan", though Fortune reported that the chairmanship decision surprised some investors [6][5]. Buffett, who is 96, stays on the board as chairman emeritus [1][3].
There are readings that cut the other way. If the first half was a one-time redeployment of cash, second-half purchases will land nearer the 2025 number and the only thing that changed in 2026 is a title. Howard Buffett's 33 years as a director may count for more than any charter would grant, in which case a family chairman is harder for a CEO to overrule than a lead independent director is [2][12]. And Buffett is still in the room as chairman emeritus, so neither role gets tested while he is there [3]. In my view the market will price Abel on the $39.4bn, and on the Alphabet position in particular, because the Alphabet position gets marked every quarter [13][14]. Fortune's Sheryl Estrada wrote that the real test "will be whether he can preserve Berkshire's discipline while making capital-allocation decisions that Buffett himself might not have made" [17]. What would count against that read: second-half equity purchases close to the $7.1bn run rate, which would make the first half a cash-clearing exercise and leave the governance split as the live question [13].
What to watch
- Second-half 2026 equity purchases: anything near the $7.1bn prior-year pace reframes the $39.4bn as a one-off.
- Whether Berkshire spells out the chairman's formal authority, and how it sits beside Susan Decker's lead independent director role.
- Whether the $10bn Alphabet commitment is fully executed and how the $37.8bn holding is marked at year end.
