Berkshire Hathaway's $45 B, 22.1% Stake Makes American Express Its Third‑Largest Holding

Why It Matters

Berkshire Hathaway’s $45 billion, 22.1% stake in American Express sends a clear signal to the market about the enduring appeal of premium‑card business models. For large‑cap investors, the move validates a shift toward integrated payment platforms that capture fee income across issuance, acquisition and processing, a model that can generate higher margins than traditional banking. The positioning also reshapes portfolio construction for institutional managers. With Amex now a top‑three Berkshire holding, fund managers may re‑weight their own large‑cap allocations, especially those tracking Buffett’s equity exposure. The stake could compress Amex’s discount to its estimated intrinsic value, prompting a re‑evaluation of other large‑cap financials that lack a closed‑loop advantage.

Key Takeaways

• Berkshire Hathaway owns 151.6 million American Express shares, a 22.1% stake worth ~$45 billion.
• The stake is Berkshire’s third‑largest holding, behind Apple (18.5%) and ahead of all other positions.
• American Express market cap stands at $203 billion; its dividend rose to $3.28 per share in 2026, yielding ~1.1%.
• Card‑fee revenue has grown at a 17% CAGR since 2018; delinquency rate averaged 1.37% over eight quarters.
• Premium‑card demand boosted Platinum Card mix and drove a 30% YoY rise in travel bookings via the Amex app.

Pulse Analysis

Buffett’s sizable allocation to American Express underscores a strategic bet on a business that marries high‑margin fee income with a defensible, affluent customer base. Unlike pure‑issuer banks, Amex captures the full transaction value chain, allowing it to monetize each swipe more effectively. This structural advantage, combined with a historically low delinquency rate, positions Amex to weather credit‑cycle headwinds better than many peers.

Historically, Berkshire’s large‑cap bets have acted as market catalysts—think Apple and Coca‑Cola—where the conglomerate’s long‑term horizon reassures investors about sustainability. The $45 billion stake could compress Amex’s valuation multiple, especially as the stock trades at a 23% discount to its 52‑week high. If Amex sustains its fee‑revenue growth and expands internationally, the upside could be material, prompting a re‑rating by growth‑oriented funds that previously shunned the stock for its slower earnings trajectory.

However, the investment is not without risk. Amex’s reliance on premium spend makes it vulnerable to macro‑economic slowdowns that curb discretionary travel and dining. Moreover, competition from fintech platforms that offer lower‑cost alternatives could erode its fee moat over time. Investors will watch the upcoming earnings release for signs that the Platinum Card momentum and international enrollment gains are translating into durable revenue streams. In the broader large‑cap arena, Berkshire’s move may accelerate a reallocation toward financials that blend traditional banking with technology‑enabled payment services, reshaping the sector’s growth narrative for years to come.
