Quantum computing stocks have been on the rise over the last couple of years due to advancements and innovations made by large companies and researchers.
This growth is fueled by funding and participation from governments — especially the US, China and the EU — as well as massive investments from tech giants like IBM, Google and Microsoft and pure-play companies such as IonQ, Rigetti and D-Wave. That support became concrete in May 2026, when the US Department of Commerce announced letters of intent to award more than $2 billion in CHIPS and Science Act incentives to nine quantum companies in exchange for minority equity stakes.(1)

Best quantum computing stocks to buy
As scientists and companies race to find the next huge innovation, some investors are grappling with understanding the potential impact of this technology and whether they should invest.
If you’re an investor with a sharp eye on the quantum surge, this best quantum computing stocks list is for you. Unlike the performance table above, these picks are selected by Finder’s investments experts from US-listed quantum computing stocks with market caps above $1 billion, ranked on financial substance, commercial traction and verified technical milestones — diversified tech giants first by market cap, then pure-play quantum companies.
While this tech giant requires no introduction, Microsoft (MSFT) is not a pure-play quantum company. Instead, it develops quantum computing technologies through its Azure Quantum platform — a cloud service launched in 2019 that gives researchers and developers access to quantum hardware — along with tools like the Quantum Development Kit (QDK).
Microsoft’s biggest quantum milestone came in February 2025, when it unveiled Majorana 1, which the company calls the world’s first quantum processing unit (QPU) built on a topological core. Microsoft says the architecture offers a path to fitting a million qubits on a single chip, though some scientists have questioned how far along the underlying technology actually is.(2)
From a financial aspect, Microsoft is looking strong. In fiscal year 2025, Microsoft reported revenue of $281.7 billion, up 15% from $245.1 billion in fiscal 2024.(3) Microsoft’s stock closed at $395.63 on July 15, 2026.(4)
Alphabet (GOOGL)
Alphabet (GOOGL), the parent company of Google, runs one of the world’s most advanced quantum research programs through its Google Quantum AI division, which operates its own dedicated chip fabrication facility in Santa Barbara, California.
In December 2024, Google unveiled Willow, a 105-qubit superconducting chip that cleared two long-sought milestones: error rates that fall as more qubits are added — a fundamental requirement for fault-tolerant computing — and a benchmark computation completed in under five minutes that Google says would take today’s fastest classical supercomputers longer than the age of the universe.(5) The findings were published in the journal Nature. Google makes its quantum hardware accessible to developers through Google Cloud.
Alphabet’s overall business is enormous. Full-year 2025 revenue reached $402.8 billion, up 15% from $350 billion in 2024, with Google Cloud growing 48% to $63.4 billion for the year.(6) Alphabet’s stock closed at $370.92 on July 15, 2026.(7)
IBM (IBM)
Another global tech giant founded in 1911, International Business Machines (IBM) specializes in computing, artificial intelligence (AI) and quantum technologies, primarily generating revenue through enterprise software, cloud services and hardware. IBM is not a pure-play quantum company, but it is a leader in developing quantum hardware, software and cloud services through IBM Quantum, and it says it will deliver the world’s first large-scale, fault-tolerant quantum computer — IBM Quantum Starling — by 2029, one of the most aggressive roadmaps in the industry.(8)
IBM’s finances have been solid, with full-year 2025 revenue of $67.5 billion, up from $62.8 billion in 2024.(9) But investors should know the stock hit severe turbulence in July 2026, when IBM shares fell 25% on July 14 — the worst single-day drop in the company’s history — and closed at $217.07 on July 15.,(11) The plunge came after IBM warned that preliminary second-quarter revenue and profit would miss expectations as large deals failed to close, with full results due July 22, 2026.(12)
IonQ (IONQ)
The first pure-play quantum computing stock in this list focuses on developing and commercializing quantum computing technologies. IonQ launched in 2015, and it is most notable for specializing in trapped-ion quantum processors, which customers access through major cloud platforms and IonQ’s own cloud service.
IonQ’s growth has been dramatic. The company reported $130 million in revenue for 2025, up 202% from $43.1 million in 2024, making it the first public quantum company to top $100 million in annual revenue under generally accepted accounting principles (GAAP).(13) For 2026, IonQ is guiding for revenue between $225 million and $245 million.(13) The company has also been on an acquisition spree, completing purchases of Oxford Ionics and Vector Atomic in 2025 to strengthen its hardware stack.(14)IonQ (IONQ) stock remains volatile, closing at $37.51 on July 15, 2026, after falling roughly 38% in a month during a broader pullback in speculative tech.(15)
D-Wave Quantum (QBTS)
D-Wave Quantum (QBTS) is the only quantum computing company to offer both annealing and gate-model quantum systems — making it the most commercially mature pure play on this list. Founded in 1999 and headquartered in Palo Alto, California, D-Wave has paying customers across finance, logistics and life sciences, and its systems are accessible via the cloud and on-premises deployments.
D-Wave posted full-year 2025 revenue of $24.6 million, up 179% from $8.8 million in 2024, and ended the year with $884.5 million in cash and investments.(16) The company also received a letter of intent from the US Department of Commerce under the May 2026 CHIPS Act quantum initiative, and secured a deal for 50% capacity of one of its Advantage2 annealing systems for a quantum research facility in Lombardy, Italy.(1),(16) The stock closed at $18.27 on July 15, 2026.(17)
Rigetti Computing (RGTI)
Rigetti Computing may be lesser known outside quantum computing circles, but it remains one of the most watched pure plays in the sector. Founded in 2013, it focuses exclusively on quantum computing technologies, built around its superconducting quantum processors.
Financially, Rigetti is the riskiest name on this list. Revenue fell from $12 million in 2023 to $10.8 million in 2024, and it slid further to $7.1 million in 2025, with a net loss of $216.2 million for the year.(18),(19) The company is well capitalized, though, ending 2025 with $589.8 million in cash and investments, and it has notched technical and commercial wins — including a 99.9% two-qubit gate fidelity milestone and an $8.4 million order from India’s Centre for Development of Advanced Computing (C-DAC) for a 108-qubit system expected to ship in late 2026.(17) The stock closed at $15.25 on July 15, 2026.(20)
Quantum Computing (QUBT)
Quantum Computing (QUBT), or QCi, is the most speculative pick on this list — a pure-play company focused on quantum optics and integrated photonics. Its products are built around thin-film lithium niobate (TFLN) photonic chips, and in 2025 the company opened its Fab 1 chip manufacturing facility in Tempe, Arizona, and raised over $1.5 billion to fund its growth strategy.(21)
QCi’s revenue base is still tiny relative to its valuation. First-quarter 2026 revenue totaled roughly $3.7 million, up from $39,000 a year earlier, with most of that increase coming from its acquisitions of LSI and NuCrypt in early 2026.(22) The stock has been extraordinarily volatile since its massive 2024 run-up and closed at $8.04 on July 15, 2026.(23)

What are quantum computing stocks?
Quantum computing stocks are regular stocks of companies that are developing or investing in quantum computing. They can either be pure-play quantum computing companies or larger corporations, such as IBM and Microsoft, that participate in the quantum computing industry via supporting technologies.
Quantum computing is an advancement in computing that harnesses the behavior of quantum physics through machines that use qubits. While regular computers hold information in two positions — 1 and 0 — qubits can hold a superposition of all possible states, making them far more powerful than regular bits for certain problems.
Why do people want to invest in quantum computing stocks?
The appeal of quantum computing stocks is twofold, at least. Firstly, quantum computing could impact numerous industries in the world — and in a strong way. The innovations alone could become a huge leap in human history and technology, not to mention its applications.
The second reason is the potential long-term payout if the technology matures, supported by heavy government and corporate backing — though that outcome is far from guaranteed.
