Quantinuum’s long-awaited IPO has reignited investor enthusiasm for quantum computing, drawing fresh attention to pure-play names including Rigetti Computing (RGTI).
The listing has fueled optimism that growing investor interest, fresh capital and a maturing ecosystem could accelerate the commercialization of quantum computing across industries.
Pure-play quantum stocks including IonQ (IONQ), D-Wave Quantum (QBTS) and Quantum Computing Inc. (QUBT) are once again attracting heightened attention from growth-focused investors.
Rigetti stands out among peers for its 108-qubit Cepheus-1 system launch, a debt-free balance sheet and an ambitious roadmap targeting quantum advantage.
Despite those positives, Rigetti’s commercial business remains in its early stages, losses continue to mount and its valuation already reflects considerably lofty expectations.
In the year-to-date period, Rigetti shares have plunged 30.7%, making it the weakest performer among the four major pure-play quantum companies tracked by analysts.
IonQ has emerged as the clear outperformer among peers, gaining 13.4% year to date, while QUBT and QBTS have lost 22.1% and 28.7%, respectively.
Rigetti’s quantum systems are accessible through Rigetti Quantum Cloud Services, Amazon Braket, Microsoft Azure Quantum and qBraid, giving enterprise customers multiple access points.
Management expects additional revenue recognition from previously announced Novera system shipments and a C-DAC deployment later this year, offering some near-term revenue visibility.
First-quarter 2026 revenues climbed to $4.4 million, driven primarily by Novera QPU shipments and research-related contracts, though enterprise adoption remains limited.
Rigetti reported an operating loss of $26 million in the quarter, reflecting continued heavy investment in research and development to advance its technology roadmap.
Management reiterated its goal of reaching approximately 1,000 qubits with 99.9% two-qubit gate fidelity within about three years, alongside improvements in speed and chiplet-based scaling.
In 2026, Rigetti is expected to experience a 257.3% improvement in revenues, while earnings per share are expected to remain negative but improve 71.9% year over year.
Rigetti is currently trading at a price-to-book ratio of 8.75X, which is meaningfully higher than the industry average of 4.88X, and carries a Value Score of F.
While Quantinuum’s IPO has renewed optimism for the broader quantum sector, analysts note it does not materially change Rigetti’s near-term commercial fundamentals.
With a Zacks Rank of 3 (Hold), existing investors may consider maintaining their positions while monitoring execution against the company’s commercialization roadmap and upcoming technology milestones.
