New York, June 16, 2026, 09:11 (EDT).
- Rigetti Computing closed Monday at $22.70, up 8.2%, on heavy volume of about 44.9 million shares.
- The move was driven mainly by a broader quantum-computing rally, not a fresh Rigetti earnings release.
- The next major test is whether Rigetti can turn its 108-qubit platform, customer deployments and partnerships into larger revenue.
Rigetti Computing, Inc. stock rallied Monday as investors rotated back into quantum-computing names. RGTI finished at $22.70, up 8.2%, after trading between $22.14 and $23.565 during the session. The stock’s market value was about $7.6 billion before Tuesday’s open, underscoring how much future growth is already reflected in the price.
The immediate spark came from sector sentiment. D-Wave Quantum led the group higher after Mizuho lifted its D-Wave price target to $35 from $29 and kept an “overweight” rating, according to Investopedia. Rigetti and IonQ also rose sharply in sympathy, a familiar pattern in quantum stocks, where news for one company can quickly reprice the whole basket. Investopedia Hewlett Packard Enterprise also added a fresh industry headline Monday, saying it expanded relationships with Intel, Quantinuum, QuEra, Quantum Machines, Rigetti and others to build hybrid quantum-supercomputing systems. Hybrid here means quantum processors working alongside classical supercomputers, not replacing them. HPE executive Trish Damkroger said the goal is to speed the “transition from research to real-world application.” HPCwire
For Rigetti, the stock reaction matters because the company is still being valued mostly on technical progress and future adoption, not current earnings power. In the first quarter, Rigetti reported $4.4 million in revenue, a $26.0 million operating loss and $569.0 million in cash, cash equivalents and available-for-sale investments. Operating loss means the core business lost money before items such as interest income and accounting gains. CEO Subodh Kulkarni said Rigetti remained focused on “disciplined execution against our roadmap to quantum advantage,” a term that refers to quantum computers solving useful problems better than classical computers.

The bull case is straightforward but still speculative. Rigetti has a large cash cushion, no debt, a generally available 108-qubit Cepheus-1-108Q system and ongoing work on chiplet-based scaling. A qubit is the basic unit of quantum information; more reliable qubits are central to building useful quantum machines. The company also reported 99.8% median two-qubit gate fidelity on its 9-qubit system and said it had achieved fidelities as high as 99.9% on prototype systems, both important because lower error rates make quantum calculations more useful.
The bear case is valuation and commercialization. A multibillion-dollar market cap against $4.4 million of quarterly revenue leaves little room for disappointment. Quantum competition is also getting tougher after Quantinuum’s public-market debut; the Honeywell-backed company raised $1.68 billion and was valued at $17.63 billion in its Nasdaq debut, while Reuters noted that commercial adoption across the industry remains limited and development costs are high.
The next major catalyst for Rigetti investors is the next quarterly update, especially any evidence that 108-qubit access, Novera quantum processing unit sales, HPE-related work or government and research customers are converting into repeatable revenue. Based on verified facts today, RGTI looks risky rather than clearly cheap. The stock may remain attractive to investors who want exposure to a high-upside quantum hardware story, but the current price already assumes meaningful progress before that progress is fully visible in the income statement.
