The company complements its systems with instruments, services, and training that support consistent use and outcomes over time. We believe Intuitive Surgical benefits from a strong business model, deep clinical expertise, and a large installed base that encourages ongoing adoption. Shares detracted during the quarter as procedure growth trends moderated and investors grew cautious about spending by hospitals amid a more uncertain macro backdrop.

While these factors weighed on sentiment, we continue to believe in Intuitive Surgical’s strong market position and ability to benefit from the ongoing shift toward minimally invasive care.”

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:

A few years from now, you’ll wish you’d owned this stock.

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.

Get the ticker for our new “Underdog” pick and the full BTI case study for just 99 cents.
