GOOGL vs QBTS: How Alphabet and D-Wave Quantum Compare (2026)

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. GOOGL and QBTS share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined GOOGL and QBTS exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Alphabet is the parent company of Google and is one of the most diversified technology businesses in the world. Search advertising (Google.com search results) remains the single largest revenue contributor and one of the highest-margin businesses ever built. YouTube is the second-largest advertising property online and the largest video platform globally. Google Cloud Platform (GCP) is the third-largest hyperscale cloud after AWS and Azure and has finally turned operating profitable in 2024.

D-Wave Quantum (QBTS) is a quantum-computing company best known for pioneering quantum annealing, an approach specialized for optimization problems such as scheduling, logistics, and resource allocation. It offers access to its quantum systems and hybrid quantum-classical solvers through its Leap cloud service, and it is also developing gate-model quantum computers to broaden its addressable applications beyond annealing. D-Wave sells quantum-computing-as-a-service, professional services, and, in some cases, systems, targeting enterprises and government customers experimenting with quantum approaches to hard computational problems. The company is early-stage and generates only modest revenue relative to its market interest; like other pure-play quantum names, its valuation rests far more on the long-term promise of quantum computing than on current financials. D-Wave became publicly traded through a SPAC merger and trades on the New York Stock Exchange. It is a highly speculative way to gain exposure to the nascent and uncertain quantum-computing theme.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• GOOGL drivers: Defending Search against AI disruption; Gemini and the model race.
• QBTS drivers: Quantum annealing for optimization; Expansion into gate-model systems.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Antitrust pressure remains intense (the US DOJ Search case ruling, plus EU and Indian regulatory actions). For QBTS, quantum computing is an early, unproven commercial market, and D-Wave's revenue is small relative to investor attention, with ongoing operating losses and cash burn that likely require additional capital and can dilute shareholders.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick GOOGL if you believe its drivers more; QBTS if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the GOOGL and QBTS guides.

GOOGL. Alphabet trades at a meaningful discount to Microsoft and to the broader Mag 7 average, reflecting the market's worry about AI displacement risk to Search. If Google defends its core position, the multiple has room to expand.

QBTS. D-Wave cannot be meaningfully valued on current earnings because revenue is small and it operates at a loss; the market prices it on the long-term promise of quantum computing and on theme sentiment, which makes traditional P/E inapplicable. The stock is extremely volatile and highly speculative, capable of large swings on news, funding, or sector enthusiasm. All figures are approximate and should be verified against the latest filings.

Headline figures (approximate, early 2026): GOOGL shows revenue (ttm) ~$370 billion, operating margin ~32%, net income (ttm) ~$110 billion, eps (ttm) ~$9.00; QBTS shows stage Early-stage commercial; small revenue relative to market interest, core technology Quantum annealing, plus development of gate-model systems, delivery Leap quantum cloud service, hybrid solvers, and professional services, revenue (ttm) Modest, in the low tens of millions or less (approximate, verify).

GOOGL and QBTS are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
