Rigetti Computing vs. D-Wave Quantum: Which Quantum Computing Stock Is the Better Buy?

The article compares two speculative quantum-computing stocks: D-Wave reported a $53.3 million second-quarter operating loss versus Rigetti’s $28.1 million, while its first-half backlog rose 1,120% year over year to $35.5 million. The U.S. government invested up to $100 million in each under the 2022 CHIPS and Science Act. D-Wave is presented as having a clearer near-term revenue path, while Rigetti’s general-purpose system offers broader potential but a longer route to meaningful revenue; the article characterizes D-Wave as lower risk and Rigetti as higher risk and higher reward.

Analysis

The key valuation risk is treating backlog as de-risked revenue. Conversion timing, cancellation terms, customer concentration and gross economics matter more than the headline growth rate; if bookings slip or require heavily subsidized deployments, QBTS’s apparent visibility may not reduce financing risk. The prospective federal support is also not a durable substitute for commercial cash flow: verify award conditions and timing before crediting it against dilution risk.

QBTS’s move into gate-model hardware could broaden its ceiling, but it also creates integration and capital-allocation risk while its annealing business is still being judged on conversion. RGTI’s cloud access via Amazon may improve distribution, but does not establish meaningful demand or favorable economics. Longer term, cloud platforms and established quantum developers could capture the customer relationship and economics even if specialist hardware advances.

Near term (days), this is a sentiment-driven, high-volatility theme rather than a clear earnings catalyst. Over 1–3 months, watch reported bookings converting to recognized revenue, cash runway, customer concentration and any funding award details. Over 6–18 months, logical-qubit progress and repeat commercial workloads—not technical milestones alone—will determine whether either company earns a durable premium. Contrarian point: calling QBTS the lower-risk choice may overstate backlog protection; RGTI’s broader technical ambition is not yet evidence of superior commercial capture. No valuation-based pair is justified without current enterprise values and comparable revenue/backlog quality.

Key Decisions for Investors

• Avoid treating either stock as a conventional growth investment; keep exposure small and do not add solely on backlog or government-support headlines.
• For a higher-conviction catalyst trade, wait for QBTS filings to show backlog conversion into recognized revenue and cash collection. If conversion disappoints or cash use remains elevated, reassess the long thesis rather than extrapolating bookings.
• Track RGTI’s customer deployments and economics through cloud channels; Amazon’s involvement is a distribution signal, not proof of material revenue. Reconsider the thesis if deployments fail to produce repeat usage or if technical progress does not translate into customer demand.
• Do not initiate a QBTS/RGTI pair on the article’s relative-risk framing alone. First compare current enterprise values, cash runway, dilution, backlog cancellation/conversion and revenue quality; a sharp deterioration in either company’s guidance or financing position would be a thesis-falsifying alert.
