American Express is a premium payments franchise — a ~$300 stock that has defied skeptics for decades by maintaining pricing power, a wealthy customer base, and a closed-loop network that gives it unique competitive advantages. While Visa and Mastercard dominate transaction volume, AmEx dominates the high-spending, high-margin segment.
And no one knows this better than Warren Buffett. Berkshire Hathaway holds a staggering $45.5 billion in American Express — 151.6 million shares — making it Buffett's second-largest public equity position after Apple. Unlike Bank of America, which Buffett is trimming, he's holding AmEx with diamond hands.
With 8 out of 18 funds buying, American Express has one of the strongest institutional buy signals in the financial sector.

Buffett's $45.5 Billion Conviction
Before we discuss the broader institutional picture, we need to spotlight the elephant in the room: Berkshire Hathaway holds 151.6 million shares of American Express worth approximately $45.5 billion.
This is Buffett's second-largest position after Apple, and he's holding — not selling. Compare this to Bank of America, where Buffett is actively trimming. The contrast is telling. Buffett clearly views American Express as a superior business to hold long-term, likely because of:
- Brand premium: AmEx can charge merchants higher fees because its cardholders spend 3-5x more than average
- Closed-loop network: Unlike Visa/Mastercard, AmEx is both the network and the issuer, capturing economics from both sides
- Affluent customer base: AmEx cardholders are more affluent, more loyal, and less likely to default
- Subscription-like revenue: Annual card fees from Platinum, Gold, and Business cards create recurring revenue
When the greatest investor in history holds $45.5 billion in a single stock and refuses to sell, it's the ultimate endorsement.
Who's Buying American Express in 2026?
Based on the most recent 13F filings (Q4 2025):
1. Vanguard Group — $13.8 Billion (Increased)
Vanguard grew its AmEx position to $13.8 billion, reflecting the stock's increasing weight in financial and consumer indices.
2. T. Rowe Price — $2.4 Billion (Increased)
T. Rowe Price added to its already substantial $2.4 billion AmEx position. The active manager clearly sees continued upside in the premium payments story.
3. Fidelity Investments — $2.5 Billion (Increased)
Fidelity increased its holdings to $2.5 billion, with both active and index strategies contributing to the growth.
4. Baker Bros Advisors — $742.8 Million (Increased)
Baker Bros significantly expanded its AmEx position to $742.8 million — one of its largest non-healthcare holdings. This cross-sector conviction signals that Baker Bros sees American Express as a premium franchise trading below fair value.
5. Appaloosa Management (David Tepper) — $98.5 Million (Increased)
Tepper added to his AmEx position at $98.5 million, continuing his pattern of accumulating high-quality financial stocks.

7-8. Additional institutional buyers are contributing to the 8-fund buying count, reflecting broad-based institutional demand.
Who's Selling American Express?
1. Millennium Management (Israel Englander) — $61.8 Million (Decreased)
Millennium trimmed its AmEx position to $61.8 million. Given Millennium's high-turnover, multi-strategy approach, this likely reflects tactical adjustment rather than fundamental bearishness.
2. D.E. Shaw & Co. — $13.7 Million (Decreased)
D.E. Shaw reduced its small AmEx position to $13.7 million, potentially redirecting capital toward stocks with stronger quantitative signals.
3. Bridgewater Associates — $9.6 Million (Decreased)
Bridgewater trimmed its modest $9.6 million stake, consistent with broader portfolio adjustments.
4. Third Point (Dan Loeb) — $3.7 Million (Decreased)
Dan Loeb's Third Point reduced its small AmEx position to $3.7 million.
5. Balyasny Asset Management — SOLD Entire Position
Balyasny completely exited American Express. This continues Balyasny's pattern of exiting financial sector positions this quarter — the firm also sold its Wells Fargo and Charles Schwab stakes.
Why the Smart Money Loves American Express
The 8-to-5 buying ratio is solidly bullish, especially considering the quality of the buyers:
1. The Buffett Anchor Berkshire's $45.5 billion position is more than a data point — it's a structural anchor. Buffett has held AmEx for decades, through recessions, financial crises, and competitive threats. His continued holding while selling Bank of America speaks volumes about his relative conviction.
2. Premium Positioning in a Digital World American Express has successfully navigated the digital payments revolution by doubling down on premium. While neobanks and fintechs compete for mass-market consumers, AmEx's wealthy cardholders are the most coveted customers in financial services. They spend more, default less, and willingly pay annual fees.
3. Millennial and Gen-Z Adoption AmEx has successfully attracted younger affluent consumers with products like the Platinum Card and Gold Card, which emphasize experiences (airport lounges, dining credits, streaming credits) over traditional rewards. New card member acquisition has been strong.
4. Fee Revenue Growth Annual card fees — particularly from the $695 Platinum Card — create subscription-like revenue that is less cyclical than transaction-based income. As AmEx adds features to premium cards, fee revenue continues to grow.
5. International Expansion AmEx's international business is growing faster than domestic, driven by expanding merchant acceptance networks and affluent consumer adoption in Europe and Asia.
What This Means for Individual Investors
American Express presents one of the strongest institutional conviction profiles in the financial sector:
Buffett's hold is the headline. When the world's greatest investor maintains a $45.5 billion position while actively selling other bank stocks, it signals extraordinary confidence in AmEx's long-term value.
Eight funds buying creates strong demand. The combination of large institutional buyers (Vanguard, T. Rowe, Fidelity) and active hedge funds (Baker Bros, Appaloosa, Citadel) creates both structural and opportunistic demand.
The sellers are small and tactical. Unlike Bank of America where the selling is heavy and fundamental, AmEx's sellers are mostly trimming small positions. The total selling volume is a fraction of the buying.
Valuation is the primary risk. At ~$300, American Express trades at premium multiples reflecting its premium business model. If consumer spending weakens or credit quality deteriorates, the stock could face pressure.
13F data is backward-looking. These filings reflect positions from approximately 45 days ago.
