IQM’s Nasdaq Debut Could Change the Quantum Race for D-Wave

IQM Quantum Computers, Europe's first publicly traded quantum computing company, has listed on Nasdaq, intensifying competition in the quantum computing sector. While IQM poses competitive threats to D-Wave through its strong engineering reputation and European market presence, the broader competition may ultimately benefit the industry by driving innovation and helping investors differentiate between quantum firms. D-Wave faces pressure to distinguish itself despite strong commercial momentum with record Q1 bookings of $33.4 million.

This Quantum Computing Stock Is Poised for a Sharp Selloff in the Second Half of 2026

Rigetti Computing faces significant downside risk despite quantum computing hype. The company's $5.6B market cap is disconnected from its $7M shrinking revenue, resulting in an extremely stretched valuation. Ongoing share dilution through its ATM program and government funding equity stakes, combined with falling sales, could trigger a sharp pullback if investor enthusiasm cools.

Quantum Stocks Face a 2028 Cash Test. Here's What Investors Should Know.

Quantum computing stocks including IonQ, IBM, D-Wave, Rigetti, and Quantum Computing Inc. are competing in the quantum computing race, but success may depend less on technology and more on cash runway and dilution risk. The critical test for these companies will be reaching 2028 with sufficient financial resources.

The Quantum Bubble Is Real Enough to Take Seriously

The quantum computing industry faces potential valuation concerns despite real technological progress. Pure-play quantum companies like D-Wave and Rigetti show impressive stock gains but trade at extremely high price-to-sales multiples (700x+ for D-Wave) with minimal revenues. While some companies like IonQ demonstrate strong commercial traction and substantial cash reserves, the sector faces profitability challenges, high R&D costs, and increasing competition from tech giants like Intel and IBM entering the quantum space.

Quantum Computing Stocks IonQ, Rigetti Computing, and D-Wave Quantum Sent Shockwaves Through Wall Street With This $857 Million Warning

Insiders at quantum computing companies IonQ, Rigetti Computing, and D-Wave Quantum have collectively sold nearly $857 million in stock over the past two years, while insider buying has been virtually nonexistent. This insider selling activity raises concerns about valuations and the early-stage adoption challenges of quantum computing technology, despite the sector's significant growth potential.

Why Rigetti Computing Stock Just Crashed

Rigetti Computing stock fell 9.2% on June 24, 2026, despite earlier gains from Trump Administration quantum computing executive orders. While the orders promoting quantum development by 2028-2031 initially sparked bullish trading, the sell-off appears driven by profit-taking from day traders. Analysts warn Rigetti may not achieve profitability until 2031 or later, making it a volatile and risky investment despite government support.

D-Wave’s New Simulator: How Does It Change the Quantum Computing Landscape?

D-Wave announced a new gate-model quantum computing simulator that could help the company expand beyond its traditional government and academic customer base. While the simulator initially boosted QBTS shares by 8%, the company faces challenges with declining Q1 revenue ($2.9M) despite strong bookings. The simulator's primary near-term value is demonstrating D-Wave's commitment to dual-platform quantum computing, though analysts remain broadly bullish with a consensus price target of $36.80, representing 46% upside potential.

After Receiving $100 Million From the Trump Administration, Is Rigetti Computing Stock a Screaming Buy?

Rigetti Computing received $100 million in CHIPS Act funding from the Department of Commerce as part of a $2 billion quantum computing investment across nine companies. While the government support provides strategic credibility and non-dilutive capital for R&D milestones, the company's extremely high valuation (P/S ratio of ~700) relative to its modest $10 million in trailing sales and ongoing operating losses make it a risky investment despite the funding boost.

Better Quantum Computing Stock to Buy: IonQ vs. Rigetti

IonQ emerges as the superior quantum computing pure-play stock compared to Rigetti Computing, leveraging its trapped-ion technology that achieves 99.99% 2-qubit gate fidelity and generating significantly higher revenue ($65M in Q1 vs. Rigetti's $4.4M). While both companies pursue different quantum computing approaches, IonQ's superior accuracy, greater computational capacity, and stronger market traction position it as the better investment, though diversification through quantum computing ETFs is recommended given sector risks.

Is Rigetti Computing Stock a Buy Right Now?

Rigetti Computing's stock has fallen from an October 2025 all-time high of $58 to around $21, raising questions about its investment potential. The quantum computing company received up to $100 million in U.S. government funding and tripled Q1 2026 revenue to $4.4 million, but remains unprofitable with significant operating losses. With $400+ million in cash, Rigetti has runway to develop commercially viable quantum applications, though success depends on long-term market adoption and faces intense competition from pure-play quantum companies and tech giants like Google and IBM.

3 Quantum Computing Stocks Down Sharply -- but 1 Offers Exceptional Value

Quantum computing stocks have experienced a valuation reset after a strong rally in April-May. While Rigetti Computing and IonQ show impressive technology and growth, their valuations appear stretched. D-Wave Quantum stands out as offering better value with strong booking momentum, major enterprise contracts, and a more reasonable valuation that may underestimate its commercial potential.

IonQ, Rigetti, and D-Wave Are Surging Again. Is Quantum Computing Finally Real?

Quantum computing stocks IonQ, Rigetti, and D-Wave have surged 50%+ since late March following a $2 billion federal investment announcement. However, the author cautions that useful quantum computing remains a decade or more away, and these stocks trade at extreme valuations with no profits, making them highly vulnerable to market sentiment shifts.

Google Rejects Quantum Funding Over Government Equity Strings

Google declined a $2 billion federal quantum computing grant due to conditions requiring government equity stakes, which would have slowed research timelines. The rejection divides the quantum sector into two camps: funded companies (IBM, GlobalFoundries, Rigetti, D-Wave, Infleqtion) gaining government validation and infrastructure, versus unfunded tech giants (Google, Microsoft, IONQ) retaining autonomy. IBM targets its first scalable quantum system by 2029, while Google's Willow chip demonstrates quantum advantage through independent development.

After Receiving $100 Million in Government Funding, Are Rigetti Computing and D-Wave Quantum the Best Quantum Computing Stocks?

The U.S. government invested up to $100 million each in quantum computing companies Rigetti Computing and D-Wave Quantum as part of a diversified bet on different quantum technologies. However, the analyst cautions that this government investment should not be viewed as validation of these specific stocks. Rigetti faces accuracy challenges with its superconducting approach, while D-Wave leads in annealing technology but has yet to prove its dual-rail qubit architecture claims. The analyst prefers trapped-ion technology companies like IonQ and Quantinuum due to their superior accuracy metrics.
