Moody’s (MCO) Is One of Warren Buffett’s Longest-Held Holdings; See Why

Moody’s Corporation (NYSE:MCO) is among the best Warren Buffett stocks.

Buffett added Moody’s Corporation (NYSE:MCO) to his portfolio back in 2000, when the financial services company spun off from Dun & Bradstreet. As of Q4 2010, Warren Buffett held 28.42 million shares worth $754.14 million. Although reduced, the company’s stake in Moody’s remains significant. As of Q4 2025, Berkshire holds 24.67 million shares, which translates into a $12.60 billion stake.

Moody’s Corporation (NYSE:MCO) is widely held by hedge funds as well, with 91 out of 1,041 hedge funds remaining bullish on the stock. The combined hedge fund stake in the stock totals $25.54 billion as of Q4 2025.

The bullish case for Moody’s Corporation (NYSE:MCO) rests on regulatory privilege, embedded demand, and capital-light growth. As of April 20, 2026, over 80% of covering analysts keep bullish ratings on the stock, with the $535 consensus price target implying over 17% upside potential.

In its Q4 2025 investor letter, Ironvine Capital Partners, an independently owned, public equity management firm, argued that Moody’s and S&P function almost as near monopolies within global debt markets, as U.S. and European authorities depend on their ratings when buying bonds and measuring risk. As a result, issuers that choose not to obtain these ratings often face higher borrowing costs.

This dynamic puts Moody’s Corporation (NYSE:MCO) in a strong position to benefit from GDP-linked debt growth, which requires minimal capital. This leaves the company with room for share buybacks and dividend payments.

Meanwhile, Qualivian Investment Partners, an investment partnership focused on long-only public equities, discussed in its Q4 2025 investor letter how the moat is translating into performance, with the third quarter of 2025 featuring adjusted EPS of $3.92, record revenue of $2.01 billion (+11%), and an adjusted operating margin of 53% (+500 basis points). The quarterly performance was driven by strong, higher-margin MIS issuance activity.

Additionally, a bullish thesis on Daniel’s Deep Dive noted that the company’s oligopolistic position, alongside S&P and Fitch, is reinforced by SEC approval barriers, institutional dependence on external ratings, proprietary verified data, and high switching costs, arguing that the risk of AI-driven disruption may be overstated. Daniel’s Deep Dive is a Substack newsletter focused on fundamental stock analysis.

Management’s Q4 2025 call further reinforced this, reporting record full-year 2025 revenue exceeding $7.7 billion, an adjusted margin of 51.1%, and adjusted EPS of $14.94. The company rated a record $6.6 trillion debt, delivered 60% growth in private-credit revenue, and achieved 97% recurring analytics revenue in the fourth quarter, along with 97% retention among GenAI customers.

At the same time, Moody’s Corporation (NYSE:MCO)’s management also outlined plans to return at least 90% of 2026 free cash flow to shareholders, reflecting their confidence in the company’s growth outlook.

Moody’s Corporation (NYSE:MCO) is a global provider of credit ratings, research, and risk analysis, helping investors and businesses make informed financial decisions.

While we acknowledge the risk and potential of MCO as an investment, our conviction lies in the belief that some AI stocks hold greater promise for delivering higher returns and doing so within a shorter time frame.

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…

This prediction might not be bold at all:
