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 the funds we read directly from SEC filings, the largest American Express position in the Q2 2026 13Fs (period ending 30 June 2026) is Berkshire Hathaway at $51.28B (151,610,700 shares). Measured against the size of each filer's book rather than in dollars, the most concentrated holder is Berkshire Hathaway, where American Express is 17.1% of everything they report. Every figure here is aggregated by CUSIP from the filer's own information table with put/call rows excluded — a 13F lists options beside shares, and adding them together is what produces the inflated stakes quoted elsewhere. Filings lag roughly 45 days: this is positioning as of 30 June 2026, not today, and not investment advice.

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 holds American Express, and how much it matters to them
Read from each filer's Q2 2026 information table (period ending 30 June 2026).
| Fund | Position | Shares | Share of the fund's 13F book |
|---|---|---|---|
| Berkshire Hathaway | $51.28B | 151,610,700 | 17.1% of $299.25B |
| Citadel Advisors | $106M | 312,334 | 0.1% of $171.84B |
| Millennium Management | $27M | 81,107 | 0.0% of $142.92B |
| Renaissance Technologies | $12M | 34,580 | 0.0% of $72.62B |
| Bridgewater Associates | $10M | 29,582 | 0.0% of $24.38B |
The last column is the one worth reading. A multi-strategy fund reporting a $100B+ book can hold a large dollar amount of American Express that means almost nothing to it, while a concentrated fund holding less in dollars may have several percent of its entire book in the name. Rankings by dollar value hide exactly that difference.
Who added and who cut
Comparing each filer's Q1 2026 table with its Q2 2026 one, by share count — the change is what shows conviction, not the size of the position.
| Fund | Q1 2026 shares | Q2 2026 shares | Change |
|---|---|---|---|
| Renaissance Technologies | 550,880 | 34,580 | -94% |
| Millennium Management | 343,161 | 81,107 | -76% |
| Bridgewater Associates | 21,777 | 29,582 | +36% |
| Citadel Advisors | 403,396 | 312,334 | -23% |
| Berkshire Hathaway | 151,610,700 | 151,610,700 | +0% |
A fund absent from this table reported no American Express position in either quarter.

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.
