Two consecutive sessions of selling have trimmed the quantum computing cohort, and the retail crowd is already calling a bottom. That reading is wrong. IONQ, RGTI, QBTS, and QUBT remain priced for a future that is not coming on any timeline that justifies current valuations. The pullback is noise. The valuation problem is structural.
The Rally That Preceded the Dip Was the Problem
To understand why the current levels are still indefensible, you have to start with what the market just came from. Rigetti Computing surged 17% on May 22, stacking on top of a 19% move the prior session. D-Wave Quantum added 13% on top of its own 19% Thursday gain. QUBT and IONQ participated in kind. This was not a rerating on fundamentals. It was a speculative rotation trade driven by AI-quantum convergence narratives and retail momentum, the same mechanics that produce meme rallies in any sector the algorithm-chasing crowd decides to adopt.
The two-day selloff that followed was not capitulation. It was the first exhale after a months-long sprint that left the entire cohort extended well beyond any rational anchoring.
The Numbers That Make the Case
Rigetti trades at roughly 592 times price-to-sales. Quantum Computing Inc. trades at roughly 606 times. These are not analyst estimates that can be massaged — they are the quotient of market capitalization divided by actual reported revenue. Rigetti’s full-year 2026 revenue is expected to land around $23 million. The market is pricing it at over $8.6 billion. D-Wave reported Q1 2026 revenue of $2.86 million, down 81% year over year. Its bookings narrative — a 2,000% surge to $33.4 million — is doing the work the income statement cannot.
IonQ is the group’s strongest fundamental case by a significant margin. Q1 2026 revenue came in at $64.67 million, up 755% year over year, with full-year guidance raised to $260-270 million. That is real growth. It is also not enough to justify the valuation at current levels, and IonQ sets the ceiling for what the rest of the cohort can reasonably aspire to claim. Every name below IonQ on the fundamental ladder is borrowing credibility from a story that is not theirs.
Meme Stock Mechanics in a Lab Coat
The quantum computing pure-plays now share the defining characteristics of meme stocks: extreme valuation multiples disconnected from current revenue, heavy retail participation, coordinated sector moves on no company-specific news, recurring shareholder dilution through stock-funded capital raises, and a narrative that substitutes future possibility for present performance. The lab coat does not change the mechanics. A stock trading at 600 times sales with no path to profitability in the near term is a meme stock regardless of how sophisticated the underlying science is.
The technology is real. Quantum computing will matter. Neither of those statements is in dispute. What is in dispute is whether any of these companies, at these prices, reflects a rational assessment of the probability-weighted present value of that future. The answer is no, and the margin of error is not small.
The 35% That Still Has to Come
A 35% decline from current levels would not bring this cohort to fair value. It would bring it to a level where the valuation conversation becomes less absurd — where price-to-sales multiples compress from the high hundreds into ranges that have at least some precedent among high-growth technology names in the pre-profitability stage. That is the floor of credibility, not the destination of a correction. The stocks would still be expensive after a 35% decline. They would simply no longer be indefensible.
The correction has started. It has not finished. Anyone buying this dip on the assumption that two red sessions constitute a reset is underwriting the same thesis the momentum crowd was running a week ago, with less upside and the same downside. The valuation overhang does not clear on profit-taking alone. It clears when the cohort gets rerated against a sober reading of revenue timelines, dilution trajectories, and the distance between scientific progress and commercial deployment at scale.
Two bad days in a meme cycle is not a bottom. It is an invitation to stay short.
