Quantum computing is attracting capital at a pace that would have seemed improbable only a few years ago. The appeal is easy to understand. If the technology can move beyond today’s experimental systems, it could help solve certain problems that are difficult or impractical for conventional computers. The harder question is when and whether that promise will translate into durable commercial returns.
The investment case is being built before the technology is fully proven. That makes quantum computing less a conventional growth story than a wager on a future market. We believe that its future is one in which today’s funding, research and corporate experimentation might establish the foundations for tomorrow’s breakthroughs.
A surge in funding and attention
Investor interest has become harder to dismiss. According to Nasdaq, quantum technology startups attracted $12.6 billion in venture and private funding in 2025, with roughly 90% directed toward quantum computing. Notably, more than six times the 2024 level. The sector is also drawing substantial corporate and government backing. Recent examples include IBM’s announced $10 billion R&D investment over five years and $2 billion in US government commitments to quantum companies over three years.
Public markets are helping make quantum a more visible investment theme. More specialist companies have indeed entered the market, while established technology businesses are investing in research, hardware and related capabilities. In fact, Nasdaq’s 2026 analysis has identified 247 companies with quantum-related patents among a broader group of firms working across AI and other technology themes. Demonstrating evidence of an expanding ecosystem, even if not all of those companies are pure-play quantum businesses.
This distinction matters. The opportunity is not limited to companies that build quantum processors. It may also involve companies that provide components, software, cloud access, specialist services and cybersecurity tools, as well as larger technology firms developing quantum capabilities alongside established businesses.
Why the technology matters
Conventional computers process information using bits, represented as either zero or one. Quantum computers use quantum bits, or qubits, which can exhibit behaviours that allow them to represent and process information differently. This does not make them faster at every task. Rather, quantum machines may eventually offer an advantage for particular classes of problems.
Potential applications include modelling molecules and materials, supporting drug discovery, and tackling selected optimisation problems. In finance, researchers and businesses are exploring uses such as portfolio optimisation; in industry, quantum tools could help with complex supply-chain problems. These remain areas of potential, not a guarantee of practical advantage or commercial success.
The distinction is important for investors as quantum computing is not simply a more powerful laptop or data centre. Its value, if realised, is likely to come from solving specific problems that conventional systems struggle with and not replacing classical computing across the board.
Spending before the payoff
Some companies are investing now not because quantum computers are ready to transform their operations, but because building expertise takes time. Businesses can experiment with cloud-based systems, identify relevant problems, recruit specialist talent and prepare data and infrastructure before the technology matures.
That preparation has a defensive dimension, too. Quantum computing could eventually threaten some of today’s encryption methods, so organisations are beginning to assess how they would protect sensitive data. The timing and scale of that threat remain uncertain, but cybersecurity planning can begin well before large-scale, fault-tolerant quantum computers are commercially available.
Even if the largest anticipated gains from quantum computing remain years away. We believe that the preparation phase may itself create business opportunities for cloud providers, software companies and cybersecurity firms. McKinsey reported in April 2026 that more than 300 global companies were adopting quantum technology, an indication that corporate engagement is broadening beyond academic research.
The risks behind the excitement
The technology still faces significant engineering challenges. Quantum systems are vulnerable to errors and environmental noise, and building reliable, scalable machines remains difficult. Commercial uses may also prove narrower than early forecasts suggest. A breakthrough in laboratory performance, on its own, does not establish that a system can solve a valuable business problem at a competitive cost.
For investors, this creates a wide gap between technological promise and investable outcomes. Funding announcements can signal confidence in a field without proving that a particular company will achieve commercial scale. Specialist companies may face high research costs, long development timelines and uncertain revenue. Meanwhile, established technology companies may have greater resources, but quantum computing is only one part of their broader investment portfolios.
The sector’s rapid rise in funding and public-market visibility can also encourage expectations to run ahead of evidence. Investors therefore need to distinguish between a large potential market and the portion that a company can realistically capture. This includes technical progress and repeatable customer demand as well.
A long-term bet, not a near-term verdict
Quantum computing may become an important technology, but its investment story is still taking shape. The recent influx of capital reflects strategic positioning as much as near-term earnings prospects, with investors, companies and governments trying to secure expertise and options in a field that could become significant.
That makes selectivity essential. Rather than treating “quantum” as a single investment category, investors can examine where a company sits in the ecosystem, how much of its value depends on quantum computing, what evidence supports its technical claims, and how it can fund development while commercial demand remains uncertain.
The central question is not simply whether quantum computing will matter. It is which problems it will solve, who will pay for those solutions, and which companies will capture the value. For now, investor interest is a bet on the answers and not proof that they are already known.
