Best Quantum Computing Stocks For 2025
You might think of quantum computing as having three basic classes of public investments at this point: the individual specialist companies like IonQ, D-Wave, and Rigetti; the diversified large-cap and big-tech options like Nvidia, Google, Microsoft, Amazon, and IBM; and ETFs like QNTM and QTUM for those who want to broadly invest in the technology itself.
If your goal is to maximize upside and you’re prepared to stomach plenty of volatility, IonQ, D-Wave, and Rigetti are strong candidates.
IonQ excels with stable, high‑fidelity trapped‑ion qubits offering full connectivity, long coherence, and robust error rates, as well as deep IP and strategic acquisitions.
D‑Wave pioneers large‑scale quantum annealing, with thousands of qubits optimized for real‑world optimization tasks, commercial uses, and proven performance improvements with Advantage2.
Rigetti offers a full‑stack superconducting gate‑model platform with in‑house fabrication (Fab‑1). It also provides a developer‑friendly cloud API (Forest/Quil), which enables rapid prototyping and algorithm tuning.
Amazon, IBM, and Microsoft are the most prudent quantum computing exposures for more strategic investors, as they offer diversified technology platforms while developing quantum services. These companies are more stable investments while still maintaining some level of quantum upside potential.
Google (Alphabet) is also compelling because of its substantial research capabilities and integration potential across its technology ecosystem. Where Google can excel especially is in how its quantum initiatives can benefit from synergistic relationships with its AI and cloud computing divisions.
Google in many ways is like a closed-end venture fund, with the various moonshot innovations it backs internally (e.g., AI, quantum computing, autonomous vehicles, augmented reality, life sciences).
If you’d prefer a broader diversified approach, the Defiance QTUM ETF blends specialized quantum innovation with stability from larger tech firms to help better balance risk and reward.
Ultimately, quantum computing is an exciting field that can eventually help solve complex problems faster. But it’s very much an early-stage field with a longer time horizon to it, and these investments can be highly volatile.
