Welcome to the AI Economy
When you hear “AI,” what do you picture? Chips? Chatbots? Big tech? That was part of the first chapter. But the next chapter of AI could look very different in our daily lives — from autonomous vehicles, to how doctors screen for disease and maybe even data centers space. Welcome to the AI economy. AI is moving beyond the technology sector and deeper into the real economy. And we think that changes where investors should be looking.
Chapter 1: From building AI to using it
For the last few years, much of the AI story has been about building the technology. Now, we're starting to see another question matter: Who can actually put AI to work?
Enterprise AI is gaining traction and not only where you might expect. Legal and medical administration, industries that have historically been slower to adopt new technology, are among the larger enterprise use cases outside of coding. That matters because the next phase of AI may not reward every company equally. Simply spending on AI is one thing. Turning it into better business outcomes is another.
Chapter 2: AI has a physical problem
But there's another side to this story. AI may feel digital. Building it is extremely physical. Start with chips. AI demand can accelerate quickly. Semiconductor supply cannot.
Adding new memory chip capacity can take three to four years or more. And the broader buildout requires more than semiconductors. Data centers, power systems, energy storage, and the industrial infrastructure around them draw on a wide range of critical materials.
Across six materials tracked in the update — copper, lithium, nickel, cobalt, graphite, and manganese—the leading refining country accounted for an average of approximately 72% of global refined production in 2025.
So the challenge is not simply mining more material. It is also building and diversifying the refining capacity needed to turn those materials into usable inputs. And then there's electricity. A historic amount of electricity, as demand for AI has resulted in the largest expected step-up in U.S. electricity demand growth in a century. AI may live in the cloud. But the cloud still plugs into the grid. And it’s creating demand for the physical infrastructure underneath them.
Chapter 3: When constraints create new frontiers
And when existing infrastructure hits constraints, something interesting can happen. We start looking for new solutions. Sometimes in unexpected places. Like space.
Launch costs are roughly 95% lower than they were 65 years ago, helping make more experimentation economically possible. One highly experimental idea? Orbital computing.
In theory, orbital computing could benefit from more consistent solar generation than here on Earth, and a data center in orbit may not need the same land or gride connection as one on Earth.
Are we about to put all our data centers in space? No. But the fact that we're even exploring ideas like this tells you how far the AI economy could reach.
Chapter 4: AI leaves the data center
And AI isn't only changing infrastructure. It's increasingly entering everyday life. One of the clearest examples is robotics. Robotaxis are already operating commercially in more than 30 cities. More than 50 companies are developing humanoid robots. And the estimated cost of building one has fallen more than 30-fold in a decade. The shift — from AI that can generate an answer to AI that can sense, decide and act—could open a much broader set of applications. Healthcare is another.
By 2030, one in six people globally is expected to be 60 or older. That means potentially more patients and more healthcare demand without necessarily having more medical resources. In one randomized mammography-screening study, AI support increased cancer detection by as much as 50% for certain age groups. It's an example of where AI could potentially help scarce clinical resources go further.
Key takeaways
Put it all together and AI no longer looks like one isolated technology trend. It looks like a connected economy. An economy builds on chips, materials, power, and infrastructure – and expressed through increasingly real-world applications — like robotics, healthcare and potentially new frontiers such as space. But the evidence, economics, and timing are not the same across every part of that economy. For investors, the next phase of AI may be less about asking: “Who is building AI?” And more about asking: “Where is AI beginning to change the economics?” Because that’s where the next chapter gets interesting.

Investing involves risk, including possible loss of principal.
Al technology relies on large data sets, which can lead to inaccuracies. Companies in Al face competition, rapid obsolescence, and depend on demand from various industries. Regulatory scrutiny could limit AI development, with data collection facing closer examination and potential fines. Country-specific regulations could also impact Al and big data companies.
