How to Invest in AI

  • Artificial Intelligence (AI) is driving headlines, but it’s difficult to define AI or capture its full potential in a single investment exposure.
  • More than a chatbot, AI is supported and used by advanced technologies like semiconductors, cloud computing, and autonomous vehicles.
  • As AI evolves and its reach expands, investors may want to take a broader view and pursue more diverse AI exposures.

The other day I asked Alexa, “What’s AI?” The response:

“I found this on Wikipedia: AI is intelligence — perceiving, synthesizing, and inferring information — demonstrated by machines, as opposed to intelligence displayed by humans or by other animals. Intelligence encompasses the ability to learn and to reason, to generalize, and to infer meaning.”

Of course, Alexa also could have just as easily said, “I am.” But defining AI as a consumer-facing device used to play music and report the weather would be far too limiting, given how entrenched and intertwined AI is with so many parts of our economy.

AI Is a Force for Transformation, Not a Sector

It’s helpful for investors to think of AI not as a sector or industry, but rather a key catalyst of transformational changes impacting our society.

Alongside hyper-connectivity, supercomputing, and biological innovation, AI is a technological pillar that allows economies to create more value with less inputs to propel economic growth. In fact, International Data Corporation predicts that business spending to adopt AI, to use AI in existing business operations, and to deliver better products/services will have a cumulative global economic impact of $19.9 trillion through 2030 – driving 3.5% of global GDP in 2030.1

From LLMs to the AI Stack

AI is more than large language models (LLMs) like ChatGPT — it’s a transformational technology supported and used by other advanced technologies, from semiconductors and cloud computing to medical devices and autonomous vehicles. As a productivity tool that fuels innovation, AI requires advanced inputs. And AI’s entire ecosystem can be broken down into mutually reinforcing functions and technologies as part of a broader AI stack — or an AI value chain with building blocks stacked atop one another.

What’s referred to as the “AI stack” encompasses all the technologies and functions that enable AI layers. The different layers of the AI stack — infrastructure, model, and application — include specialized software, hardware, and services that make the AI engine run.

How to Invest in AI: Diversify Across the AI Stack

Viewed broadly, AI is a change agent. And so, the question investors should be asking is, “Which companies are likely to benefit from this change agent?”

To pursue the full value of AI, you may want to take a more inclusive view of its potential impacts across various sectors, industries, and companies. Rather than seek out pure AI investment exposures, it may be more beneficial to own the AI ecosystem — both the building blocks underpinning AI’s development, like computer hardware, and the companies rapidly adopting AI to drive the broader technological innovations like autonomous vehicles (Figure 3).

AI Example

Virtual Reality

AI can be used to provide motion tracking data, allowing the virtual reality or augmented reality experience to seamlessly blend with the user’s perspective.

Wearables

Machine learning algorithms and datasets can be extended to understand how you are walking, sitting, moving, or interacting with others, providing clues about your mood, physical reaction, energy level, and even context that could have consumer, military, and medical uses.

Robotics and Autonomous Vehicles

Self-driving cars use AI to make real-time decisions based on the data they gather from their sensors.

Smart Buildings, Factories, Grids, Borders

AI-powered smart devices can interact and communicate with each other, allowing them to learn human habits.

Digital Communities, Platforms and Gaming Apps

AI tools help enhance features of social media platforms and lead social media activities at scale across several use cases, including text and visual content creation, social media monitoring, ad management, influencer research, and brand awareness campaigns.

Enterprise Collaboration

Owners and operators of the storage for the large data sets needed to run and store the information to support AI solutions.

Data Storage and Compute Components

Computer hardware includes semiconductors that generate the massive computing power AI needs to train models and the storage systems needed to retain data.

Cloud Services

Cloud service providers offer data storage and computing performance at a massive scale.

AI and Data Processing Software

Companies that create AI-based software for consumers and businesses can help them interpret and collect data.

Researchers and Labs

Research focused on developing AI large language models supports the building of end-user applications.

Data Centers

AI requires large data centers and hardware to run models and calculations.

Applications

Companies that build applications use AI. 

Digital Assets

AI could be used to analyze digital asset transactions taking place on blockchain platforms, algorithmic trading, and contract verification.

Pinpointing pure AI investment exposures, as desirable as that may sound, is challenging and, even if pure exposures do exist, they may not fully capture AI’s potential. Consider casting a wider net by focusing on the entire AI stack.

Avoiding AI FOMO When the Headlines Hit

AI is an exciting headline trend for many investors. While the buzz is real and hard to ignore, the truth is that AI’s full economic impact remains a futuristic forecast for now.

As AI continues to evolve, economists and consultants will continue to debate the magnitude of its growth and macroeconomic impacts. But the possibilities for how AI may fuel those gains are increasing, as the AI stack expands to include more enablers and potential beneficiaries.

By investing in the full AI stack, you may be able to better capture the full potential of AI as a transformational driver of growth across a broad range of sectors and industries.
