Rigetti CEO Admits No Quantum ROI Yet; IonQ Drops 8%, D-Wave 5%

Rigetti Computing (NASDAQ:RGTI) fell 5% to $10.57 on Thursday, a day after CEO Subodh Kulkarni told investors that no quantum company — his own included — can yet prove a return on investment over classical computers. The admission landed hard. IonQ (NYSE:IONQ) sank 8% to $31.36, D-Wave Quantum (NYSE:QBTS) slid 5% to $10.16, and Quantum Computing Inc. (NASDAQ:QUBT) dropped 5% to $5.86.

The trigger was Rigetti's Q3 2026 report, released November 10. Revenue came in at $1.41 million — a 27.5% year-over-year decline and a wide miss against the $3.52 million consensus. Operating losses widened to $33.19 million from $20.55 million a year earlier. Management held its full-year 2026 revenue outlook at roughly $20 million, contingent on customer acceptance of the C-DAC system in the fourth quarter.

What did the CEO actually say?

On the November 10 earnings call, Kulkarni described quantum computing as "still very much in the R&D phase." Then he addressed the economics head-on: "None of us are at a point where we can demonstrate ROI with quantum computing over classical computing." He added that data center managers are unlikely to commit serious commercial money until quantum shows that return. His estimate: the industry sits "roughly about three years from that point," a timeline tied to a target of 1,000 physical qubits at 99.9% fidelity or higher. Near-term sales will stay modest, he suggested, because today's buyers are mostly national labs, universities and research teams. Three years is a long horizon for growth-stock investors.

How much is macro, and how much is Rigetti?

Interest rates compounded the damage. The Consumer Price Index released November 10 showed October prices up 0.4%, above the 0.3% economists expected, pushing the 10-year Treasury yield toward 5%. Higher yields hit hardest at companies whose earnings sit years out.

The peer group's moves tell that story. IonQ reported Q3 revenue of $173.8 million, up 336% year over year — and still fell the most of the three names. That points to rates and risk appetite, not results, as the dominant force. D-Wave grew Q3 sales 20.7% year over year, but quarterly bookings fell 19% and gross margin slipped to 52.9% from 71.4% as lower-margin professional services took a bigger share of the mix. When the sector's revenue leader and its smaller rivals all drop together, it reads as a sector-wide repricing rather than a verdict on any single quarter.

Why does each company's model matter?

The four pure-plays diverge sharply in structure. Rigetti builds superconducting, chiplet-based machines, sells them on premises to national labs and universities, and offers cloud access. A small number of system deliveries drive its sales, which keeps quarterly revenue uneven and research-driven. IonQ runs a broader platform — trapped-ion computers, networking, sensing, security software and a chip foundry — giving it revenue streams beyond quantum computing itself; NVIDIA (NASDAQ:NVDA) plans to install an IonQ Superion 256 system at its Accelerated Quantum Research Center. D-Wave sells annealing systems that customers already run in production while it develops gate-model machines. Quantum Computing Inc. builds photonic systems that run at room temperature, paired with chip-packaging operations.

What comes next for Rigetti?

The bulls have real ammunition. Rigetti ended Q3 with $497.1 million in cash, cash equivalents and available-for-sale investments, and no debt. A definitive $100 million agreement with the U.S. Department of Commerce could accelerate its hardware road map. The bears counter with a widening operating loss and a CEO who expects commercial sales to stay limited until quantum advantage arrives. With Q4 customer acceptance of C-DAC now the swing factor for the $20 million full-year outlook, and Treasury yields still climbing, every quantum name — even those with the largest revenue bases — faces repricing risk in both directions.
