Better Quantum Computing Stock: IonQ vs. D-Wave

The article compares two quantum computing stocks, IonQ and D-Wave Quantum. IonQ demonstrates industry-leading precision with 99.99% 2-qubit gate fidelities and has a partnership with Nvidia, but faces massive operating losses and an extremely high P/S ratio of 65. D-Wave has achieved real-world applications through its quantum annealing technology and Leap cloud service, but revenue declined 67% year-over-year with a P/S ratio of 475. The author recommends IonQ as the relatively safer choice despite both stocks carrying significant risks and being overvalued.

D-Wave Quantum vs. QuantumScape: Which Moonshot Tech Stock Is a Better Buy in 2026?

The article compares two early-stage quantum technology companies: D-Wave Quantum, which has commercial customers and $24.6M in revenue but is burning cash rapidly with a -1,444% net margin, and QuantumScape, a pre-revenue solid-state battery developer with a stronger cash cushion and clearer path to commercialization. The author recommends QuantumScape as the better speculative bet due to its financial runway, despite both being high-risk moonshot investments years from profitability.

Why D-Wave Quantum Stock Popped Today

D-Wave Quantum stock jumped 9.2% after announcing it will host the Qubits Asia 2026 Quantum Computing User Conference in Seoul on October 28, 2026.

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.

Why I Wouldn't Touch IonQ, Even With Quantum Computing Stocks Soaring

Despite IonQ's impressive 287% year-over-year revenue growth and record quarterly results, analyst Matt DiLallo advises against investing in the quantum computing stock due to its massive losses (operating costs 5x revenue), rich valuation (55x forward sales), and high volatility. He suggests considering quantum computing ETFs instead as a safer way to gain sector exposure.

Is D-Wave Quantum a Buy?

D-Wave Quantum is a rare pure-play quantum computing company with paying customers running production workloads, including AT&T's network optimization task. However, the company faces significant challenges: it's burning cash rapidly (-$119M free cash flow over last four quarters), has doubled its share count in two years through dilution, and carries a lofty 500x price-to-sales valuation that leaves no room for error. While D-Wave is the most defensible pure-play quantum stock, investors seeking quantum exposure should consider tech giants like IBM or Alphabet instead.
