Report says Greg Abel has 34.7% of Berkshire’s portfolio tied to two AI stocks

Berkshire Hathaway’s next-generation leadership is again drawing scrutiny as a market-news post published Aug. 18, 2026 by Yahoo Finance’s distribution platform (The Motley Fool) argued that an executive commonly associated with Buffett’s succession has shaped a large portion of Berkshire’s stock exposure toward artificial intelligence-related equities.

The post centers on an allocation figure it describes as “34.7% of Berkshire Hathaway’s portfolio” being invested in two AI stocks. It frames the point as evidence that Berkshire’s long-standing, valuation-driven approach is still compatible with exposure to fast-growing technology themes, but through a concentrated lens rather than a broad basket.

Berkshire Hathaway is a conglomerate with a large equity portfolio, and the debate around its stock selection often focuses on what portion of that portfolio sits in any single thematic area. A claim that nearly a third of the portfolio is tied to only two AI-related companies, if accurate, would represent a substantial concentration relative to the diversification typically expected from a “conglomerate-style” equity strategy.

The post also highlights Greg Abel as the executive in focus, positioning him as Warren Buffett’s successor. However, the article’s specific mechanics, such as what decisions are directly attributed to Abel versus what is simply reflected in the current portfolio, are not provided in the information available here.

Berkshire itself did not disclose, in the material behind this report, any additional breakdown explaining how much of its current AI exposure should be attributed to particular executives, nor did it provide new details about whether the two AI positions were built incrementally over time or added in a single period.

In the absence of Berkshire Hathaway’s own filing-based commentary or a direct quote from the company in the material reviewed here, the 34.7% figure and the “two AI stocks” framing should be treated as a calculation reported by the market-news outlet rather than as a confirmed statement by Berkshire. Readers looking for verification would typically look to Berkshire’s most recent quarterly portfolio disclosure to identify the two companies and compute their share of the equity portfolio.

What to watch next is whether Berkshire’s next portfolio update changes the concentration in AI-related holdings, and whether Berkshire provides additional commentary around its investment process in a way that clarifies how leadership succession considerations intersect with sector selection.
