In this article, we will list the 5 Best Stocks to Buy According to Ken Griffin. Please visit 10 Best Stocks to Buy According to Ken Griffin, if you would like to see the extended list and the methodology behind it.

5. Apple (NASDAQ:AAPL)

Ken Griffin’s Stake Value: $1,500,827,597

Apple is gaining favor on Wall Street after previously being dismissed as an AI laggard. The biggest vote of confidence recently came from Warren Buffett, who openly said in a CNBC interview that he sold Apple shares “too soon.” Apple remains Berkshire Hathaway’s largest holding.

“Well, I sold it too soon,” Buffett recently said. “But I bought it even sooner. So, it worked.”

Two factors had been weighing on Apple’s stock: first, declining iPhone sales, which remain its bread and butter; and second, the lack of a clear AI strategy.

Wall Street was extremely skeptical of Apple’s (NASDAQ:AAPL) AI strategy until concerns over increasing data center spending and ROI started popping holes in the AI hype, making the Cupertino giant’s approach look increasingly prudent. Apple (NASDAQ:AAPL) spent just about $12.7 billion in CapEx last year, while major tech companies like Microsoft, Google, Meta and Amazon are expected to spend about $600 billion combined on AI infrastructure in 2026.

What about the concerns about declining iPhone sales? Earlier this year, Apple (NASDAQ:AAPL) issued a higher-than-expected revenue growth guidance for the March quarter driven by a rebound in iPhone demand. But let’s face it: Analysts are now coming to terms with the reality that iPhone sales are unlikely to keep delivering strong growth as users may not upgrade as frequently.

Apple (NASDAQ:AAPL) anticipated this shift and began diversifying into services and other higher-margin business segments. As of the fiscal Q1, Apple’s Services revenue reached an all-time record of $30 billion, accounting for about 21% of total revenue. Services gross margins are about 76%,  nearly double the 40.7% margin seen on physical products. With an installed base of 2.5 billion devices, Apple (NASDAQ:AAPL) is positioned well to keep making money despite a potential plateau in iPhone sales.

Apple ranks fifth in our list of the best stocks to buy according to billionaire Ken Griffin.

RiverPark Large Growth Fund stated the following regarding Apple Inc. (NASDAQ:AAPL) in its fourth quarter 2025 investor letter:

“Apple Inc. (NASDAQ:AAPL): AAPL shares rose in 4Q25 following better-than-feared iPhone 17 sell-through trends and stronger Services momentum. The company reported that early adoption of its on-device AI features exceeded internal expectations, particularly in North America and Europe, where attach rates for Pro models remained elevated. Wearables also returned to growth, helped by new health features and improved battery life. While macro softness in China remained a headwind, investors responded positively to evidence of content and advertising revenue re-acceleration within the Services segment, which delivered double-digit growth.

We continue to view Apple as one of the world’s most resilient and profitable businesses, supported by a massive installed base, ecosystem lock-in, and growing high-margin revenue streams. As Apple Intelligence features proliferate across devices, we expect multi-year upgrades, improved monetization, and expanded recurring revenue. With strong cash generation, ongoing share repurchases, and disciplined capital allocation, Apple remains a compelling long term investment.”

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:

Wall Street calls this $3 stock a “Melting Ice Cube.” They said the same thing about BTI before it returned 90%.

My name is Inan Dogan. I’m the co-founder and Research Director of Insider Monkey. I have an important message for you today.

Since March 2017, my stock picks have returned 16.5% annually. Today, I’ve found an opportunity even bigger than my British American Tobacco call.

Two years ago, Wall Street wrote off British American Tobacco (BTI) as a “melting ice cube.” The stock had crashed 40% from its peak, and consensus said the business was dying.

We looked under the cover and realized they were wrong.

We alerted our subscribers, and BTI returned 90% in just 16 months.

Now if you had invested just $10,000 in BTI in June 2024, you’d be sitting on $19,000 in October 2025.

Today, we have identified a nearly identical pattern in a digital-first giant trading at $3.

While the market panics over a surface-level revenue decline, our PhD-led research shows management has actually surgically cut $100 million in waste to focus on high-margin growth.

This pattern is a hallmark of our 16.5% annual return track record. The current opportunity offers a 400% upside potential—dwarfing even our 90% BTI return.
