You can invest in artificial intelligence through individual public companies or AI-themed exchange-traded funds (ETFs). Those routes offer very different kinds of exposure: a company may build AI models, supply chips or data-center infrastructure, or adopt AI in its own business, while an ETF follows an index or an adviser’s selection strategy. Neither an AI label nor an investor’s enthusiasm establishes that an investment will perform well.
Parag Agrawal is identified as the founder and CEO of AI startup Parallel and the former CEO of Twitter, but the available source does not establish that he is a billionaire or that he has recommended buying AI securities. Treat the title’s billionaire framing as unverified, not as a reason to invest.
How can you invest in AI?
Public-market investors can seek AI exposure by buying individual stocks or by investing in an AI-themed fund. The right comparison is not simply “AI stock versus AI ETF”: it is what each investment actually owns, how it defines AI exposure, and how much risk and concentration it adds to a broader portfolio.
Individual public companies
Companies across the AI supply chain may develop models or software, make semiconductors, provide cloud computing, networking, memory, data-center capacity, power or cooling, or use AI in other industries. A company’s connection to AI does not show how much of its revenue comes from AI, how profitable that business is, or whether its stock is attractively valued. Consider the company’s overall business and financial disclosures rather than treating an AI association as a stand-alone investment case.

AI-themed ETFs
An ETF can hold a basket of companies selected for a stated AI-related objective. Some funds track an index; others are actively managed, with an adviser choosing companies it believes may benefit from AI transformation or are connected to a particular AI ecosystem. The First Trust Bloomberg Artificial Intelligence ETF prospectus, for example, says the fund seeks results that generally correspond to the Bloomberg Artificial Intelligence Index before fees and expenses (SEC-filed prospectus). That objective describes an intended strategy, not a guarantee of results.
Actively managed strategies may reach across semiconductors, cloud services, memory, networking, data-center infrastructure, power and cooling, software, deployment platforms, and cybersecurity. These are possible areas of exposure, not proof that any particular holding will benefit. Read the fund’s current documents to see how its actual portfolio implements its stated approach.
How to compare AI funds
Fund names and thematic labels are not enough to establish what a fund owns or how it behaves. Before choosing between funds, compare the current prospectus, summary prospectus, holdings, and fee schedule.
| What to compare | Questions to ask |
|---|---|
| Objective and selection method | Does the fund track an index with published rules, or does an adviser select holdings? How are companies added, removed, and weighted? |
| Definition of AI exposure | Does the fund focus on direct AI products, infrastructure suppliers, adoption by other businesses, or a broader ecosystem? An AI screen does not necessarily indicate how much AI revenue a company earns. |
| Holdings and concentration | What are the largest positions? How concentrated is the fund by company, sector, or geography? Do its holdings overlap substantially with funds you already own? |
| Costs and trading | What is the current expense ratio? Check the prospectus for turnover and consider that buying and selling ETF shares may also involve trading costs. |
| Risk disclosures | What does the fund say about technology competition, valuation swings, concentration, execution, or the risk that its chosen theme or ecosystem underperforms? |
| Fit with your plan | Does the investment’s volatility and time horizon fit your broader financial plan, circumstances, and risk tolerance? |
Fund holdings, fees, and strategies can change, so check the latest disclosures rather than relying on an old comparison or a fund’s name. A BlackRock outlook cautions that its AI screen does not represent a view of companies’ current or future AI revenue, exposure, or prospects (BlackRock AI investing outlook). A thematic classification is a way of sorting companies, not evidence of expected returns.
What risks come with AI investing?
- Competition and changing technology: Companies can lose an advantage as models, hardware, business practices, or customer preferences change.
- Valuation risk: Share prices can fall if expectations embedded in valuations are not met, even when a company remains active in AI.
- Concentration: A fund focused on a narrow theme or ecosystem may depend heavily on a small set of companies or technologies. A Harbor prospectus describes the risk that competitors or other platforms could win adoption instead (SEC-filed Harbor prospectus).
- Selection risk: An index’s rules or an active adviser’s choices can leave a fund with companies that do not benefit as expected—or exclude companies that do.
- Capital and execution demands: Building and operating AI infrastructure can require substantial investment, while companies still face the challenge of turning adoption into durable business results.
These risks apply in different ways to individual stocks and funds. An ETF can spread exposure among holdings, but it cannot remove the risks of its underlying companies or of a concentrated theme. SEC registration or filing is not SEC approval of a fund as an investment or validation of its prospectus.

A July 2026 Kleiner Perkins podcast description identifies Agrawal as founder and CEO of Parallel and former CEO of Twitter, and describes an episode about AI-agent web infrastructure (Kleiner Perkins podcast). That supports describing him as an AI startup founder and former Twitter CEO. It does not establish billionaire status or a public recommendation from him to buy AI stocks or ETFs. A person’s role in the industry, even if accurately described, is not evidence that a security is suitable or likely to rise.
