Who Is Buying American Express? Hedge Fund Activity in 2026

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.

Quick Answer

Across 18 tracked funds, 8 are buying AXP versus 5 selling, and the anchor is Berkshire Hathaway's 151.6 million shares (~$45.5B) — Buffett's second-largest position, held not trimmed. Buyers include Vanguard ($13.8B), T. Rowe Price ($2.4B), Fidelity ($2.5B), Baker Bros ($742.8M), Appaloosa, and Citadel, all increasing. On the sell side, Millennium, D.E. Shaw, Bridgewater, and Third Point made small trims while Balyasny exited entirely. 13F filings are public and lagged ~45 days — a signal of institutional positioning, not investment advice.

American Express at a Glance

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.

6. Citadel Advisors (Ken Griffin) — $97.7 Million (Increased)

Ken Griffin's Citadel grew its AmEx stake to $97.7 million, adding exposure to the premium payments franchise.

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.

FAQ

How concentrated is institutional ownership in American Express (AXP)?

American Express is dominated by long-term institutional holders, anchored by Berkshire Hathaway's 151.6 million share position ($45.5B). Large passive providers like Vanguard, plus active managers such as T. Rowe Price and Fidelity, round out the top of the holder list.

Which hedge funds were the biggest AXP buyers in the latest 13F snapshot?

Q4 2025 filings show 8 of 18 tracked funds buying AXP, including Vanguard, T. Rowe Price, Fidelity, Baker Bros, Appaloosa (David Tepper), and Citadel. Millennium, D.E. Shaw, Bridgewater, and Third Point trimmed, while Balyasny exited the position entirely.

How current is the disclosed AXP institutional data?

US 13F filings are published up to 45 days after each calendar quarter ends, so any reported AXP position is typically 1.5 to 4.5 months old. Mid-quarter activity only becomes visible after the next filing window closes.

Does American Express fit a dividend or a growth profile?

American Express pays a regular dividend but yields modestly given its share price, so the institutional thesis usually combines income with capital appreciation. Funds emphasize the closed-loop network, premium cardholder spend, and recurring annual fees as drivers of long-term total return.

How can I track AXP institutional flows without overreacting to stale data?

You can monitor 13F filings on EDGAR or via consolidated views like Freenance's Smart Money. Treat hedge fund moves as one input — they are delayed, do not capture derivatives or short exposure, and should be combined with your own research and risk tolerance. This is not investment advice.
