The Investment Case for Quantum Computing

A recent thematic investment note from MarketScreeners has highlighted quantum computing as a compelling long-term investment opportunity, pointing to projections that the global market could surge from around $500 million in 2021 to $65 billion by 2030. The note, which compiles a list of publicly traded companies active in the field—from startups to multinationals—points to a compound annual growth rate (CAGR) exceeding 50%.

Quantum computers differ fundamentally from conventional machines by using qubits that can represent both 0 and 1 simultaneously, delivering an exponential leap in processing power. Calculations that would take today’s supercomputers millennia could, in theory, be solved in minutes. The note suggests that sectors including cryptography, pharmaceutical research, artificial intelligence, finance and logistics stand to be reshaped as the technology matures.

With governments and large enterprises pouring massive sums into research and development, the authors frame quantum computing as a disruptive theme investors should consider, arguing that the expected exponential growth merits a portfolio allocation.

Contextualizing the Growth Projections

Assessing the $65 Billion Target

The jump from $500 million to $65 billion in nine years is dramatic. It assumes that quantum computers will move from limited, experimental systems to practical, commercially viable machines across multiple industries. While major players such as IBM, Google and a host of startups are advancing the technology, the timeline for error-corrected, general-purpose quantum computers remains uncertain. Many estimates from research firms are based on extrapolations of early venture funding and government contracts, not proven revenue streams, making the forecast as much about investor expectations as technical milestones.

The Promotional Angle

The note originates from MarketScreeners, a platform providing thematic stock recommendations whose business model involves highlighting emerging themes to attract investors. The list of quantum computing companies is likely curated to showcase stocks that may benefit from increased attention, and it can present an optimistic view that does not fully account for execution risk, timeline delays, or the fact that many pure-play quantum firms are pre-revenue. Additionally, large multinationals included in the list may have only a fraction of their business tied to quantum computing, diluting the potential upside.

What This Means for Individual Investors

For individual investors intrigued by the quantum computing opportunity, the note’s projections should be weighed carefully:

  • Given the market is still nascent—$500 million globally—and the $65 billion projection depends on breakthroughs, consider limiting any allocation to a small, speculative portion of a well-diversified portfolio rather than treating it as a core holding.
  • Since the thematic list includes everything from early-stage start-ups to large caps, purchasing a broad exchange-traded fund (ETF) focused on quantum computing or advanced computing themes can reduce single-stock risk and capture the theme more broadly.
  • Look beyond the hype: many quantum companies have no significant revenue yet. Favour those that also have robust existing business lines (for instance, large IT firms) that can fund R&D without relying solely on equity markets, as timelines to profitability remain uncertain.

As with all thematic investing, the key is to understand what you own and why—not to buy into a story alone.
