Abel's Two-Pronged Play: Berkshire Bets on AI's Power Hunger While Deepening Its Tokyo Roots

CEO Greg Abel links Berkshire's $17B Alphabet stake to AI power demand, boosts buybacks, and reaffirms decades-long Japan holdings.

Greg Abel is sketching out a more integrated investment thesis than Berkshire Hathaway shareholders have seen in years, one that ties the conglomerate's surging stake in Alphabet directly to the electricity needs of the artificial-intelligence boom — and positions its Japanese trading houses as a decades-long pillar rather than a tactical wager.

Speaking to Reuters and CNBC on Wednesday, the Berkshire chief executive said the company sees substantial opportunities through its Berkshire Hathaway Energy subsidiary to supply power for the build-out of AI data centers. He explicitly linked that view to the conglomerate's sharply increased position in Alphabet, the Google parent that Berkshire expanded by roughly 83 percent during the second quarter of 2026, adding shares worth about $17 billion in the process.

That buying spree had already elevated Alphabet to Berkshire's third-largest equity holding, according to the latest portfolio filing. But Abel's comments supply something investors had been waiting weeks for: a strategic rationale. Rather than a straightforward valuation play, the Alphabet stake now reads as a bet on both sides of the data-center equation — demand through the tech giant, supply through Berkshire's own power-generation assets.

A capital machine shifting from hoard to deploy

The Alphabet position is hardly an isolated move. Abel's Berkshire has been noticeably more aggressive with its balance sheet across the board. During the second quarter of 2026, he said the company bought roughly $20 billion more in stock than it sold — the first time in more than three years that net purchases turned positive.

That deployment has drawn down the conglomerate's once-record cash pile from $397.4 billion at the end of the first quarter to $365.5 billion by June 30. The direction of travel is clear: capital is being put to work rather than parked.

The same offensive posture shows up in the housing sector. Berkshire increased its stake in homebuilder Lennar by 30 percent in late August, bringing the position to nearly $1.2 billion. As of June 30, the company held 13.4 million Lennar shares — 13.1 million of them Class A — representing a 6.2 percent ownership stake. The addition came despite headwinds in the construction industry, signaling confidence in the sector's fundamentals.

That bet was complemented by the July completion of Berkshire's $72.50-per-share cash acquisition of Taylor Morrison, a deal carrying an equity value of roughly $6.8 billion and an enterprise value of about $8.5 billion. Chief executive Sheryl Palmer remains in place and will oversee the integration into Berkshire's Clayton Properties Group housing unit, which encompasses 15 regional builders.

Tokyo stays central

None of this new activity has dimmed Abel's enthusiasm for Japan. He told Bloomberg a day before his Alphabet comments that Berkshire intends to hold its positions in the five largest Japanese trading houses — Mitsubishi, Itochu, Mitsui, Sumitomo and Marubeni — for decades. The remarks helped lift shares of those companies on the Tokyo exchange and underscored that the Japan exposure is structural rather than opportunistic.

Abel also pushed back against concerns that rising Japanese borrowing costs might undermine the strategy. Speaking to CNBC, he characterized the yen-denominated debt financing as still appropriate, dismissing the notion that higher credit costs in Japan pose a fundamental problem for the trading houses in Berkshire's portfolio.

The company is also exploring deeper ties with its Japanese partners, with Abel indicating Berkshire wants to pursue more joint investments and acquisitions with the five firms on a global scale.

Operating results tell a mixed story

The second-quarter numbers behind all this activity show why Abel might feel emboldened to press forward on multiple fronts — and why some caution remains warranted. Total operating earnings rose 16 percent to $12.98 billion, but the composition was uneven.

Manufacturing, services and retail led the way with a 24 percent gain to $4.47 billion. Berkshire Hathaway Energy improved 27 percent to $891 million, and the BNSF railroad advanced 6 percent to $1.56 billion. The insurance side, however, lagged: underwriting income fell 13 percent to $1.73 billion, while investment income from insurance assets slipped 9 percent to $3.06 billion.

That divergence — strong industrial results offset by a softer insurance book — tempers the headline growth figure and helps explain why the stock itself has been subdued. The shares closed Thursday at €655,500, sitting 4.4 percent below their 52-week high of €686,000 reached in August. A relative strength index of 51.4 points to a market that is neither overbought nor oversold, reflecting an investor base that appears to be waiting for more clarity even as Abel presses ahead with his repositioning.

The broader picture taking shape is of a conglomerate returning capital to shareholders — buybacks were accelerated last week, nudging the stock up 0.5 percent — while simultaneously leaning into growth themes from AI infrastructure to Japanese trading to American homebuilding. Abel may be extending Warren Buffett's playbook, but he is clearly writing some new chapters of his own.
