For a long time, Berkshire Hathaway was Warren Buffett's investment vehicle.
The company is built atop an insurance foundation, which could be important with Greg Abel as CEO.
Berkshire Hathaway (NYSE: BRKA)(NYSE: BRKB) is a Wall Street icon because of Warren Buffett's long and successful history of buying stocks. His success earned him the nickname "the Oracle of Omaha," and Berkshire Hathaway was basically a way to invest alongside the famous investor. The company's story changed in 2026, when Greg Abel took over as CEO, and Buffett initiating Berkshire Hathaway's recent purchase of Alphabet (NASDAQ: GOOG) shares hints at a new model for the company.
Warren Buffett stepped down as CEO of Berkshire Hathaway at the end of 2025, handing the reins to hand-picked successor Greg Abel. But Buffett didn't really retire; he shifted to the position of president of the board. So he is still Abel's boss and available to help out as needed. Given that Buffett initiated the company's large recent purchase of Alphabet stock, it looks like he's still calling the shots when it comes to investing.

But the Oracle of Omaha isn't making all of the decisions, noting that Greg Abel was the one who made the call on Berkshire's acquisition of Taylor Morrison Home. The difference is that Taylor Morrison Home was a strategic move that Abel hopes will allow Berkshire Hathaway to integrate its homebuilding-related businesses into one operation. That's more of an operational decision, while the purchase of Alphabet shares was an investment decision.
What's notable about these two decisions is that Abel is focused on running the business, while someone else is focused on investing. Someone else happens to be Wall Street icon Warren Buffett, but it could actually be anyone. Or, eventually, an entire team of people. That is how most insurance companies operate. Management focuses on running the business, and a specialized investment team runs the investment portfolio. At its core, Berkshire Hathaway is an insurance company.
In fact, that was Buffett's real genius. He realized he could use the float (the premiums the company holds onto while waiting to pay out claims) to invest more aggressively in stocks than most insurers do. Along the way, he created a massive conglomerate. Abel seems to be focusing on running the conglomerate while letting someone else handle the investing side.
Since Buffett was a hands-off manager as CEO, focusing most of his effort on investing, there could be a significant opportunity for Abel to improve the company's operating businesses. In other words, the split taking shape between what Abel and Buffett are doing could be an important indication of Berkshire Hathaway's future direction. And it would leave the company operating more like a traditional insurance company, which probably wouldn't be a bad outcome.
