Better Quantum Computing Stock: IonQ vs. D-Wave
Source: Motley Fool ↗ (cross-verified by 3 outlets — full list below)
IonQ and D‑Wave Quantum are the two most prominent pure‑play quantum‑computing stocks, and investors are weighing which offers a better buy despite both carrying high risk. IonQ, often dubbed the “Nvidia of quantum,” recently showcased a trapped‑ion system that achieved 99.99 % two‑qubit gate fidelity, positioning it as a leader in precision while partnering with Nvidia to install its Superion 256 system at Nvidia’s Accelerated Quantum Research Center. In the first half of 2026 the company generated $145 million in revenue—up sharply from $28 million a year earlier—but posted a $1.06 billion operating loss, and its shares have fallen more than one‑third over the past year, leaving it with a price‑to‑sales (P/S) ratio near 65.
D‑Wave’s approach relies on quantum annealing for optimization, and its Leap cloud service already runs customer workloads, delivering dramatic speed gains such as AT&T’s reduction of a one‑hour task to under 15 seconds. The firm’s revenue fell to $5.9 million in the first half of 2026, a 67 % year‑over‑year decline, while operating expenses produced a $66 million loss; its stock has dropped nearly 40 % in the last year and trades at an even higher P/S ratio of roughly 475, reflecting expectations of future revenue growth but underscoring its current unprofitability.
Given the stark financial contrasts, the analysis concludes that while both stocks remain speculative, IonQ presents a comparatively less risky option. Its Nvidia partnership lends credibility and potential ecosystem advantages, and its valuation—about 65 times sales—is far lower than D‑Wave’s 475‑times multiple. Nonetheless, the sector’s deep uncertainty means risk‑averse investors should steer clear of both, but for those seeking exposure, IonQ is deemed the safer bet with a higher probability of success.
