Quantum computing stocks have generated enormous investor excitement, but the underlying financials tell a more complicated story about long-term viability.
Rigetti Computing (RGTI), D-Wave Quantum (QBTS), and IonQ (IONQ) rank among the most closely watched names in the sector, with share prices surging dramatically over the past three years.
Despite the enthusiasm, most of these companies still report lackluster sales figures, and rising operational costs continue to raise serious questions about their staying power.
IonQ stands out most clearly from the pack, having reported second-quarter revenue of $80.1 million, representing a staggering 287% increase from the same period a year earlier.
A portion of that dramatic revenue jump stems from IonQ’s recent acquisition of SkyWater Technology, a chip foundry business, though organic sales are also trending upward independently.
IonQ’s management estimates that organic revenue alone will double for the full calendar year 2026, a milestone that would signal genuine commercial momentum beyond acquisition-driven growth.
Total sales for IonQ, including both acquisitions and organic growth, are projected to reach an estimated $455 million this year, a figure that would dwarf its smaller rivals.
With cash and cash equivalents of $3 billion on hand, IonQ faces little immediate risk of running short on capital needed to fund continued expansion and research.
Rigetti Computing (RGTI) posted impressive second-quarter revenue growth of 185%, but the raw dollar figure of just $5.1 million highlights how early-stage the company’s commercial operations remain.
Rigetti’s CEO Subodh Kulkarni acknowledged the situation plainly, stating that “commercial revenue remains early” and suggesting it could be several more years before the technology reaches meaningful commercial scale.
On the positive side, Rigetti is entirely debt-free and holds $541 million in cash reserves, giving the company a reasonable runway to continue developing its technology without immediate financial pressure.
Rigetti also recently expanded its collaboration with Hewlett-Packard and the Pittsburgh Supercomputing Center, a partnership that could help accelerate its technical progress and market credibility.
D-Wave Quantum (QBTS) delivered one of the more eye-catching data points in the sector, with bookings surging 1,120% in the second quarter to reach $35.5 million.
That extraordinary bookings growth signals strong and growing customer interest in D-Wave’s products and services, though converting that interest into recognized revenue has proven more difficult.
Taken together, IonQ’s combination of rapidly growing sales, a massive cash position, and expanding acquisition strategy makes it the most credibly positioned of the three for long-term survival.
