Top Quantum Computing Stocks to Watch in 2025

Why Quantum Computing Stocks Could Be the Next Big Investment Opportunity

Quantum computing is one of the most disruptive technologies of the 21st century. Unlike classical computers, which use binary bits (0s and 1s), quantum computers use qubits that can exist in multiple states at once. This gives them the potential to solve problems millions of times faster than today’s most powerful supercomputers.

The quantum computing market is projected to grow at a CAGR of over 30% and could exceed $125 billion by 2030. Industries such as finance, cybersecurity, healthcare, AI, and logistics are already exploring how quantum computing could give them an unbeatable competitive edge. Tech giants and startups alike are racing to develop quantum technologies that could revolutionise everything from drug discovery to encryption.

For investors, quantum computing stocks offer explosive long-term potential. While some companies are established tech giants integrating quantum computing into their ecosystems, others are pure-play startups that could deliver 10x returns if they succeed. Here are the best quantum computing stocks to buy in 2025 that could skyrocket in value.

IBM (NYSE: IBM) – The Most Established Quantum Computing Leader

IBM has been leading the quantum computing revolution for decades. Its IBM Quantum division has developed some of the world’s most advanced quantum systems, including IBM Quantum System One, which is already being used for research and enterprise applications. IBM also runs the IBM Q Network, partnering with companies like ExxonMobil, Daimler, and JP Morgan to explore real-world quantum applications.

IBM is aggressively expanding its Quantum Cloud Services (QCaaS), making quantum computing accessible to businesses. The company has already built quantum data centres in North America, Europe, and Asia and plans to release a 1000+ qubit quantum computer by 2026.

IBM’s quantum computing division is expected to grow at a CAGR of 15%-20%. The company’s overall revenue continues to rise, and its 2.55% dividend yield makes it an attractive choice for both growth and income investors. Most bullish analysts predict IBM’s stock could reach $320 per share in 2025, from its $260 that holds currently.

Should you buy IBM? IBM is one of the safest ways to invest in quantum computing, offering both growth and dividends.

Alphabet (NASDAQ: GOOGL) – Google’s Quantum Computing Powerhouse

Alphabet’s Google Quantum AI division is at the cutting edge of quantum computing research. Google made headlines in 2019 when it achieved “quantum supremacy”, proving that its quantum processor, Sycamore, could solve problems no classical computer could handle. Just recently Google launched as well Willow

Google’s quantum research focuses on developing practical quantum applications in AI, cybersecurity, and pharmaceuticals. Its next-generation Bristlecone quantum processor aims to enhance quantum error correction, a major hurdle in scaling quantum systems.

Google’s parent company, Alphabet, has a strong financial foundation, with AI, cloud computing, and advertising revenues driving growth. The bullish analysts predict Alphabet’s stock could rise to $235 per share in 2025 as it continues to dominate the AI and quantum computing industries. Currently is at $181 per share.

Should you buy Alphabet? Google’s quantum computing ambitions make it a high-quality long-term investment, especially for those looking for exposure to AI and cloud computing as well.

Microsoft (NASDAQ: MSFT) – A Quantum Computing and Cloud Giant

Microsoft is a leader in topological quantum computing, a cutting-edge approach designed to improve qubit stability and scalability. The company’s Azure Quantum platform offers quantum computing as a service, making it accessible to enterprises and researchers.

Microsoft’s partnerships with NASA, Quantum Circuits Inc., and leading universities position it as a key player in the industry. Its cloud-first strategy ensures that quantum computing will integrate seamlessly with its existing AI and enterprise software ecosystem.

Microsoft is expected to maintain a 15%+ CAGR, driven by AI, quantum computing, and cloud expansion. Analysts predict MSFT stock could reach $400-$450 in 2025.

Should you buy Microsoft? Microsoft’s low-risk exposure to quantum computing, combined with its strong presence in AI and cloud computing, makes it a solid long-term buy.

NVIDIA (NASDAQ: NVDA) – The AI-Quantum Hybrid Stock

NVIDIA is not building its own quantum computers but is playing a critical role in quantum simulation and AI integration. Its cuQuantum software enables GPUs to simulate quantum circuits, which is essential for testing quantum algorithms before hardware is ready.

NVIDIA’s partnerships with Google, IBM, and quantum startups make it a key player in the space. The company is also working on AI-driven quantum algorithms that could transform fields like cryptography and medical research.

NVIDIA is expected to grow at a CAGR of 20%+, driven by AI and data centre demand, it is a monster stock in terms of potential, although it has been suffering recently with DeepSeek release. Bullish analysts predict NVDA stock could hit $220 per share in 2025 well above its current $134.

Should you buy NVIDIA? If you want a hybrid AI-quantum investment, NVIDIA is a top choice with massive growth potential.

IonQ (NYSE: IONQ) – The Pure-Play Quantum Computing Stock

IonQ is one of the few publicly traded pure-play quantum computing companies. It focuses on trapped-ion quantum technology, which has shown superior qubit stability compared to traditional superconducting qubits.

IonQ’s quantum computers are already available on Microsoft Azure, Google Cloud, and Amazon Braket, giving it broad market exposure. The company is aggressively expanding, with plans to develop a #AQ 64 quantum processor by 2028, which could surpass current systems in computational power.

IonQ is a high-growth stock, with revenues projected to grow 40%+ annually. Analysts forecast its stock could rise to $54 per share in 2025 and currently is at $31.

Should you buy IonQ? If you’re looking for pure exposure to quantum computing, IonQ is a high-risk, high-reward investment. You will have more information on a full stock review on IonQ that we did recently.

Other Quantum Computing Stocks to Watch

Rigetti Computing (NASDAQ: RGTI) – We were doing already a review on Rigetti Computing potential looking at recent deals and developments and a bit of outlook. This is another pure-play quantum stock focused on superconducting qubits and hybrid quantum-classical systems.

D-Wave Quantum (NYSE: QBTS) – Specialises in quantum annealing, which is already being used by companies like Volkswagen and Lockheed Martin for real-world applications. If you want to know more, we also reviewed D-Wave Quantum recent deals, developments and potential stock price.

Honeywell Quantum Solutions (private) – Developing trapped-ion quantum computers with a strong focus on industrial applications.

Should You Invest in Quantum Computing Stocks?

Quantum computing is still in its early stages, but the potential is massive. Companies like IBM, Google, and Microsoft are leading the industry, while pure-play stocks like IonQ and Rigetti offer higher-risk, higher-reward opportunities.

Investing in quantum stocks now could be like investing in the early days of AI or semiconductors. As the technology advances and becomes commercially viable, early investors could see exponential returns.

If you’re looking for long-term growth stocks, quantum computing is a sector that cannot be ignored, however, at the end of the day, is your decision and you should do your own research before doing any investments. Will you take the leap into the future of computing?
