Not IonQ. Not Rigetti Computing. This Quantum Computing Stock Is the One I'd Buy and Hold Through 2030.

While IonQ and Rigetti Computing are popular pure-play quantum computing stocks, both face significant challenges including operating losses, uncertain commercialization timelines, and shareholder dilution risks. Alphabet emerges as a superior quantum computing investment, leveraging its profitable core businesses to fund quantum research, including recent breakthroughs with its Willow quantum processor that achieved a 40x error reduction. Unlike smaller competitors, Alphabet can afford sustained experimentation while maintaining profitability and reasonable valuation.

IonQ, Rigetti Computing, D-Wave Quantum, and Quantum Computing Inc. Are Shaking Wall Street to Its Core With This $1 Billion Warning

Despite impressive stock gains over two years, insiders at four major quantum computing companies have sold $1.02 billion in net shares since October 2021 while purchasing less than $4.3 million collectively. The lack of insider buying, combined with valuations exceeding 30x sales and historical precedent of tech bubbles, suggests investor caution may be warranted as quantum computing optimization could take years.

Quantum Computing Is Still Years Away. These 6 Stocks Show Who Is Closest to Real Revenue.

Quantum computing companies remain years away from profitability, with most relying on stock sales rather than customer revenue. IBM has the financial capacity to wait until 2028-2029, IonQ shows real revenue growth but heavy cash burn and dilution, while D-Wave and Rigetti have promising bookings but minimal revenue. Alphabet and Nvidia are positioned as bystanders rather than quantum revenue stories.

Should You Buy These 4 Quantum Computing Stocks Before 2027?

The article examines four quantum computing stocks—IonQ, Rigetti Computing, D-Wave Quantum, and IBM—ahead of the potential $100 billion market by 2035. While all four companies have sufficient cash reserves to continue operations, the pure-play quantum stocks (IonQ, Rigetti, D-Wave) remain unprofitable with extremely high price-to-sales ratios and uncertain paths to commercialization. IBM, as a diversified tech company with quantum computing initiatives, offers a lower-risk alternative but has underperformed the market recently.

D-Wave Quantum vs. Rigetti Computing: Which Cutting Edge Quantum Stock Is a Better Buy in 2026?

D-Wave Quantum and Rigetti Computing are both early-stage quantum computing companies with significant cash burn and unproven commercial roadmaps. D-Wave shows stronger revenue growth at 180% YoY ($24.6M) with increasing commercial adoption, while Rigetti has lower revenue ($7.1M, down 34% YoY) but received a potential $100M government contract. The author recommends Rigetti for long-term investors seeking a potential home run due to its technological prowess and deeper government support, despite both companies trading at high valuations with negative earnings.

IonQ, Rigetti Computing, D-Wave Quantum, and Quantum Computing Inc. Are Sending Shockwaves Through Wall Street With This $895 Million Warning

Despite quantum computing stocks soaring up to 1,820% over two years, insiders at IonQ, Rigetti Computing, D-Wave Quantum, and Quantum Computing Inc. have collectively sold $895.1 million more shares than they've purchased while barely buying any stock. The companies trade at extreme valuations (P/S ratios of 55.7 to 494.1), suggesting a potential bubble similar to past technology cycles.

Rigetti Turned $10,000 Into Over $81,000 in 3 Years -- and It's Still 73% Off Its High. Here's Why I Still Wouldn't Touch It.

Rigetti Computing stock has delivered exceptional returns over three years despite being down 73% from its peak, driven by quantum computing sector optimism. However, the analyst warns against investing due to the company's extreme volatility, unprofitable operations ($28.1M operating loss on $5.1M revenue), significant cash burn ($32M in H1), and sky-high valuation of 375x sales, making it unsuitable for investors seeking portfolio stability.

IonQ vs. Rigetti Computing: Which Pure-Play Quantum Stock Actually Has the Technology Edge?

IonQ and Rigetti Computing are pursuing different quantum computing technologies with distinct trade-offs. IonQ uses trapped-ion technology with superior accuracy (99.3-99.5% fidelity) and all-to-all qubit connectivity, while Rigetti uses superconducting qubits with faster operations (60 nanoseconds vs. 950 microseconds) but lower accuracy (99.1% fidelity). IonQ currently holds the technology edge with demonstrated error-correction progress and DARPA Stage B advancement, but its lead is not secure as both companies face challenges scaling their systems while maintaining performance.

What It Would Take for IonQ Stock to Reach $100

IonQ is expanding beyond quantum computing into a broader technology platform and raised its 2026 revenue outlook by 60%, with most growth coming from non-quantum segments. However, reaching a $100 share price will require the company to demonstrate recurring demand, improve economics, and successfully scale its full-stack strategy into commercial viability.

Why CoreWeave Stock Soared 12% Today

CoreWeave shares gained 12% today despite no company-specific news, benefiting from a broader rally in the AI infrastructure sector. The gains were driven by Nebius's partnership announcement with Palantir, Department of Commerce investments in quantum computing companies, and Intel's processor price increase announcement. CoreWeave remains a volatile, high-risk stock with rapid revenue growth but massive losses due to heavy capital expenditures and debt servicing.

Why D-Wave Quantum Stock Popped Today

D-Wave Quantum received up to $100 million in funding from the U.S. Department of Commerce under the CHIPS and Science Act, causing its stock to rise 10.86%. However, the government also awarded similar $100 million grants to rival quantum companies Quantinuum and Rigetti Computing. GlobalFoundries received the largest award at $375 million, suggesting it may be the government's preferred champion rather than D-Wave.

Why Rigetti Computing Popped Today

Rigetti Computing's stock surged up to 12.2% after securing $100 million in CHIPS Act funding from the Department of Commerce to advance superconducting quantum computing research. The government will receive a minority, non-controlling equity stake in the company. While the funding is a positive development for the quantum computing sector, Rigetti remains speculative as it generates minimal revenue ($5.1 million in Q2) and quantum computing is still an emerging technology.
