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.

Google Reveals Why It Turned Down Trump Administration's Quantum Funding Deal: 'In This One Specific Case…'

Google's Chief Operating Officer of Quantum AI disclosed that the company declined funding from the Trump administration's quantum computing initiative because the attached conditions would have slowed its progress. Despite this, Google continues collaborating with the U.S. government on quantum research and emphasized the need for increased basic research funding and global talent recruitment to compete with China in quantum computing 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.

The Case for Intel Over Pure-Play Quantum Firms

Intel is positioned to outcompete pure-play quantum computing firms like Rigetti and D-Wave due to its existing manufacturing infrastructure, CHIPS Act grants, and strategic partnerships with Apple and NVIDIA. While pure-play quantum firms offer technological potential, their high valuations relative to revenue and Intel's resource advantages make Intel a more attractive investment for quantum computing exposure.

Wall Street Is Wrong About This Quantum Computing Stock for 2026 -- Here's the Proof

Infleqtion, a newly public neutral-atom quantum computing company, has achieved significant milestones including defense contracts for quantum sensing hardware across three countries, $100 million in U.S. government co-investment, and integration with Nvidia's technology. Despite these accomplishments, the stock trades around $17.50 with limited market attention compared to competitors like IonQ and Rigetti.

The Pure Plays: 5 Companies Building Quantum From the Ground Up

The article profiles five pure-play quantum computing companies pursuing different hardware approaches: IonQ (trapped-ion systems), D-Wave (annealing and gate-model systems), Rigetti (modular superconducting chiplets), Xanadu (photonic quantum computing), and Infleqtion (neutral-atom systems). Each company has demonstrated significant technical milestones in 2025-2026, including record gate fidelities, distributed quantum networking, and commercial deployments. The article emphasizes that while quantum computing is making measurable progress, no single modality has yet proven definitively superior, and the field remains in early commercialization stages with paying customers and peer-reviewed results.

Quantum Computing: Hype or the Real Deal?

Quantum computing represents a fundamental shift from classical binary computing, using qubits that can exist in multiple states simultaneously. While the underlying physics is sound and progress is documentable, fault-tolerant quantum computers capable of commercial viability are likely still a decade away. Major tech companies (IBM, Google, Microsoft) and pure-play quantum firms (IonQ, D-Wave, Rigetti) are advancing the technology, but investors should adopt a diversified portfolio approach given the long development timeline, high costs, and uncertainty about which technologies will ultimately succeed.

Will Quantinuum Lift Other Quantum Stocks — Or Eat Their Lunch?

Quantinuum's IPO on Nasdaq (QNT) at a $14.3 billion valuation raises questions about whether it will boost the entire quantum computing sector or cannibalize existing players like IonQ, D-Wave, and Rigetti. The quantum sector has historically traded as a single basket, but Quantinuum's entry as an institutional-grade, government-backed company with Fortune 500 backing could reshape competitive dynamics and capital allocation within the space.
