Apple Remains Berkshire Hathaway's Crown Jewel as Buffett Hands Over the Reins

When Warren Buffett stepped down as CEO of Berkshire Hathaway at the end of 2025, he left behind a portfolio that tells a compelling story about conviction and legacy. More than anything else, the composition of that portfolio reveals not just what the Oracle of Omaha valued, but what he believes will continue to drive returns for the company under Greg Abel’s leadership. At the center of that strategy sits Apple—a position so substantial it redefines our understanding of Buffett’s approach to technology investments.

The Scale of Berkshire’s Apple Bet

The numbers speak for themselves. Based on Q4 2025 share counts and current valuations, Apple represents Berkshire Hathaway’s single largest equity holding, valued at over $60 billion. That’s nearly one-fifth of the conglomerate’s entire equity portfolio, which exceeds $300 billion in total value.

To put this concentration in perspective, only two other positions in Berkshire’s holdings exceed the $50 billion threshold. American Express, the integrated payments company, ranks second with approximately $52 billion in value, representing about 17% of the portfolio. Coca-Cola follows as the third-largest position at roughly 10% of holdings. Bank of America and Chevron round out the major positions, each accounting for approximately 9% and 7% respectively.

What makes this particularly striking is not just the size of the Apple position, but what it represents. For an investor famously skeptical of technology stocks throughout most of his career, leaving Berkshire Hathaway with a near-20% position in a consumer tech company signals profound confidence about the company’s trajectory.

Why Apple Stands Apart

The journey to this position began modestly in 2016, when Berkshire first established a stake in the iPhone maker. The position grew steadily through 2017, and by early that year, Buffett disclosed his reasoning. When he more than doubled the position, he explained to CNBC that he appreciated Apple’s characteristics: a “quite sticky product, and an enormously useful product to the people that use it.”

This wasn’t casual commentary. In his final annual letter to shareholders, Buffett specifically highlighted Apple alongside just three other companies—American Express, Coca-Cola, and Moody’s—as “household” names worthy of extended holding periods. The distinction matters. In Buffett’s framework, being a household name correlates with resilience, brand loyalty, and pricing power.

The depth of conviction becomes clear when examining Berkshire’s trading activity. During the third quarter of 2025, the company trimmed its Apple position by approximately 15%. Yet in the final quarter, sales slowed dramatically to just 4% of the holding. This deceleration suggests a strategic decision: to enter the next phase with Apple as a cornerstone position rather than continue harvesting gains.

The Succession Question and Strategic Continuity

Here’s what matters most for Berkshire shareholders moving forward: Greg Abel is unlikely to dismantle what Buffett has built, at least not immediately. Taking over the helm of a company with Buffett’s track record demands respect for the existing framework. From 1965 until 2025, Berkshire’s stock compounded at approximately 20% annually—a cumulative return exceeding 5,000,000%.

Rather than wholesale portfolio reconstruction, a more probable scenario has Abel focusing intensely on operational excellence in his first years. Major portfolio shifts would likely occur only if compelling, low-risk opportunities emerge. Why tamper with a system that has delivered such extraordinary returns? For Apple specifically, Abel inherits not just a position, but a template for identifying enduring competitive advantages.

The risk for any successor is attempting to improve upon excellence. The safer, more rational approach is stewardship—preserving what works while making incremental refinements.

Apple’s Operational Momentum

Of course, conviction based on historical positioning alone wouldn’t sustain a near-20% portfolio weight. The business fundamentals must support the thesis. In Apple’s most recent quarter—the critical holiday period—revenue climbed 16% compared to the prior year, while earnings per share surged 19%. This represents the kind of synchronized growth that suggests neither revenue expansion nor margin expansion is cannibalizing the other.

Beyond quarterly metrics, Apple’s installed base provides structural support for future monetization. The company maintains more than 2.5 billion active devices worldwide. This ecosystem isn’t just a customer base—it’s a recurring revenue platform. Through services, AppleCare, subscriptions, and ecosystem lock-in, Apple continues building higher-margin revenue streams that bolster profitability even as hardware growth moderates.

What This Means for Investors

Berkshire Hathaway’s 13-F filing provides more than a snapshot of a legendary investor’s final portfolio allocation. It’s a roadmap for thinking about durability, competitive positioning, and the difference between temporary market dominance and genuine staying power. Apple’s prominence suggests that the company has transcended the category of “good tech stock” to become something closer to a consumer staple with premium margins and brand resonance.

Whether that thesis will remain valid under Abel’s stewardship depends on execution. But the fact that Buffett chose to leave Apple as his flagship position—rather than reduce it to nominal levels or eliminate it entirely—suggests he believed the company had decades of value creation ahead. For a succession plan, that’s about as clear an endorsement as one could hope for.
