American Express (AXP), The Longest-Held Position of Warren Buffett; See Why

American Express Company (NYSE:AXP) is one of the best Warren Buffett stocks.

During the initial wave of consumer credit in the 1960s, American Express Company (NYSE:AXP) drew Buffett’s attention, prompting his acquisition of a 5% stake in the company. The company remains one of Berkshire Hathaway’s longest-held positions, appreciating significantly over the years. As of Q4 2025, the stake had grown to more than $56 billion, a massive increase from the Q4 2010 stake, valued at over $6.51 billion.

Meanwhile, American Express Company (NYSE:AXP) enjoys the confidence of hedge funds, with 83 out of 1,041 hedge funds remaining bullish on the stock. The combined hedge fund stake in the company totals $61.45 billion as of Q4 2025.

As of the same period, billionaire sentiment remains strong as well, with 22 out of 107 billionaires remaining bullish on American Express Company (NYSE:AXP), which translates into a $60.47 billion stake.

The bullish case for American Express is built on resilient spending from affluent customers, strong demand for premium cards, and a business model that continues to translate customer engagement into earnings growth and shareholder returns. While the stock is down 10% year-to-date, it climbed over 12% over the past month, as of April 20, 2026.

Meanwhile, discussing American Express Company (NYSE:AXP) in its Q4 2025 investor letter, GAMCO Investors, a diversified asset management firm, grouped AXP with other financial holdings that are benefitting from a steeper yield curve, a recovery in deal-making activity, a strong equity market, and solid spending by wealthier customers.

Additionally, Bretton Fund, a mutual fund, expressed a similar view more directly in its Q4 investor letter, noting that cardholders continued to spend and make timely payments, while the Platinum Card remained in high demand despite increasing competition. The firm also highlighted that EPS grew 15% and the stock delivered a 26% return during the quarter.

Jim Cramer commented at the start of April:

“I think that American Express was one of the worst performers. I think American Express down 17% seems pretty interesting to me. I’m willing to take a, I hate to say this, but a flyer, on some of these travel names, betting that they were too linked with gasoline. With gasoline, now breaching four dollars, but it can start coming down if the President says tonight, that the war’s going to end soon.”

Management’s fourth-quarter 2025 commentary earlier in 2026 supplemented this outlook.

The company reported record full-year 2025 revenue of $72 billion and EPS of $15.38, with card-fee growth in the double digits for the 30th consecutive quarter and strong credit quality. Millennials and Gen Z accounted for the largest share of U.S. consumer spending, while demand for premium products remained strong. The company also guided 2026 revenue growth of 9% to 10%, EPS in the range of $17.30 to $17.90, and a planned 16% increase in its dividend.

American Express Company (NYSE:AXP) operates as a global payments and premium lifestyle brand powered by technology. Its card-issuing, merchant-acquiring, and network businesses serve a wide range of customers, including consumers, small businesses, mid-sized firms, and large corporations worldwide.

The $250 Trillion AI Hype is Real. A few years from now, you’ll probably wish you’d bought this stock.

When Jeff Bezos said that one breakthrough technology would shape Amazon’s destiny, even Wall Street’s biggest analysts were caught off guard.

Fast forward a year and Amazon’s new CEO Andy Jassy described generative AI as a “once-in-a-lifetime” technology that is already being used across Amazon to reinvent customer experiences.

At the 8th Future Investment Initiative conference, Elon Musk predicted that by 2040 there would be at least 10 billion humanoid robots, with each priced between $20,000 and $25,000.

Do the math. According to Musk, this technology could be worth $250 trillion by 2040.

Put another way, that’s roughly equal to:

  • 175 Teslas
  • 107 Amazons
  • 140 Metas
  • 84 Googles
  • 65 Microsofts
  • And 55 Nvidias

And here’s the wild part — this $250 trillion wave isn’t tied to one company, but to an entire ecosystem of AI innovators set to reshape the global economy.

It’s a leap so massive, it could reshape how businesses, governments, and consumers operate worldwide.

Even if that $250 trillion figure sounds ambitious, major firms like PwC and McKinsey still see AI unlocking multi-trillion-dollar potential.

How could anything be worth that much?

The answer lies in a breakthrough so powerful it’s redefining how humanity works, learns, and creates.

And this breakthrough has already set off a frenzy among hedge funds and Wall Street’s top investors.

What most investors don’t realize is that one under-owned company holds the key to this $250 trillion revolution.

In fact, Verge argues this company’s supercheap AI technology should concern rivals.

Before I reveal the details, let’s talk about how some of the richest people on the planet are positioning themselves.

  • Bill Gates sees artificial intelligence as the “biggest technological advance in my lifetime,” more transformative than the internet or personal computer, capable of improving healthcare, education, and addressing climate change.
  • Larry Ellison — through Oracle, is spending billions on Nvidia chips and partnering with Cohere to embed generative AI across Oracle’s cloud and apps.
  • Warren Buffett — not known for tech hype — says this breakthrough could have a ‘hugely beneficial social impact.

When billionaires from Silicon Valley to Wall Street line up behind the same idea — you know it’s worth paying attention to.

Even as we admire what Tesla, Nvidia, Alphabet, and Microsoft have built, we believe an even greater opportunity lies elsewhere…

But the real story isn’t Nvidia — it’s a much smaller company quietly improving the critical technology that makes this entire revolution possible.

And judging by what I’m hearing from both Silicon Valley insiders and Wall Street veterans…
