In recent months, the valuations of popular quantum computing stocks, Rigetti and D-Wave, have reached staggering levels, raising concerns about their sustainability in the near future. Since the start of 2023, Rigetti Computing’s stock has surged approximately 3,500%, while D-Wave Quantum’s shares have risen around 1,700%. Analysts warn, however, that these inflated prices may be indicative of a forthcoming market correction.
The core issue at hand is the practicality and timeline of achieving viable quantum computing. Quantum computers, which leverage qubits—the fundamental units of information that can exist in multiple states concurrently—are proposed to outperform classical computing in solving complex problems. Despite this potential, experts assert that large-scale, fault-tolerant quantum computers remain at least a decade away from realization. Currently, no company has successfully developed a fault-tolerant system capable of real-time error correction and equipped with the necessary scale of qubits, estimated to be between 10,000 and 1 million for practical purposes.
Grand View Research predicts that the quantum computing market will grow at a modest annual rate of 21%, reaching a valuation of $4 billion by 2030. In stark contrast, the artificial intelligence sector is projected to expand at a much more impressive 36%, hitting $1.8 trillion over the same period. Industry analysts emphasize that the AI market will vastly outpace the quantum computing sector, suggesting that investments in quantum technologies may not yield the rapid returns many investors are banking on.
Focusing on Rigetti Computing, the firm specializes in superconducting quantum computing. The company prides itself on its cost efficiency through vertical integration, having control over its supply chain, including the manufacturing of quantum processors and the provision of cloud-based services. Rigetti has also pioneered multichip quantum processors to enhance system scalability. Nevertheless, their roadmap indicates that systems capable of housing 1,000 qubits won’t materialize until late 2027, indicating a significant lag before such systems can be deemed commercially viable. Currently, Rigetti’s stock trades at an astonishing 1,025 times sales, a figure that eclipses even Palantir Technologies, regarded as the most expensive stock in the S&P 500 at 120 times sales.
On the other hand, D-Wave Quantum has adopted a divergent product strategy by focusing on quantum annealers rather than gate-based systems. Although quantum annealers are limited to specific optimization problems, they are easier to scale and have allowed D-Wave to commercialize its products ahead of its competitors. The company has successfully constructed annealers with close to 5,000 physical qubits, significantly more than what many competitors are able to offer. However, despite D-Wave’s first-mover advantage and established client relationships, its stock still reflects a hefty valuation at 325 times sales. This multiple raises significant questions concerning the long-term sustainability of its stock price, particularly given that quantum computing revenue is only expected to grow at a steady 21% annually through 2030.
Overall, both Rigetti and D-Wave appear to be floating on inflated valuations that may not be justified by the current state of quantum technology. Industry experts are cautioning investors to prepare for a major correction as the market assesses the true potential and timeline for practical quantum computing advancements.
