Is Rigetti Computing Stock a Buy for High-Risk Investors?

The quantum computing race has entered a critical phase, with companies like Rigetti Computing, IBM, and Google vying for dominance. For high-risk investors, the question is whether Rigetti’s stock offers a compelling opportunity despite its financial challenges. To answer this, we must evaluate its technological leadership, financial viability, and market readiness.

Quantum Leadership: Progress, but Gaps Remain

Rigetti has made strides in 2025 with the launch of the Cepheus-1-36Q, a 36-qubit multi-chip quantum computer featuring a median two-qubit gate fidelity of 99.5%—a 2x improvement over its predecessor [2]. This system, now available on Microsoft Azure, marks a step toward scalable quantum architectures. However, competitors like IBM and Google have also advanced rapidly. IBM’s Heron R2 processor boasts 156 qubits and a two-qubit error rate of 0.371%, while Google’s Willow chip achieves 105 qubits with a 0.14% error rate [3]. Rigetti’s error rates, though improved, still lag behind Google’s, and its qubit count remains modest compared to IBM’s roadmap of 4,000+ qubits by 2025 [1].

Rigetti’s focus on modular chiplet-based designs and partnerships with Microsoft and DARPA positions it as a key player in the superconducting qubit space. Yet, its long-term vision—a 336-qubit Lyra system—remains unproven [2]. For now, the company’s leadership is defined by incremental progress rather than a clear leap over rivals.

Financial Viability: A Double-Edged Sword

Rigetti’s financials tell a mixed story. In Q2 2025, the company reported $1.8 million in revenue, a 41% drop from Q2 2024, and a net loss of $39.7 million, driven by $22.8 million in non-cash losses [2]. Operating expenses ballooned to $20.4 million, reflecting the high costs of R&D and scaling quantum hardware. However, Rigetti’s $571.6 million in cash reserves—bolstered by a $350 million equity raise—provides a buffer to sustain operations for the foreseeable future [2].

The challenge lies in translating technological progress into revenue. Rigetti relies heavily on government contracts and research collaborations, with no major commercial clients announced [3]. While this strategy ensures steady funding, it limits growth potential in a market where commercial adoption is still nascent. For investors, the key question is whether Rigetti can pivot to enterprise clients or secure partnerships that justify its valuation.

Market Readiness: A Long Road Ahead

Quantum computing remains a nascent industry, and Rigetti’s market readiness reflects this reality. The company’s partnerships with DARPA and Microsoft highlight its role in government-driven innovation, but commercial applications—such as drug discovery or optimization problems—remain theoretical for most users [2]. IBM and Google have similarly struggled to monetize their quantum advancements, with IBM’s Quantum System Two and Google’s error-corrected roadmap still years from practical deployment [1].

Rigetti’s plan to release a 100+ qubit system by year-end is ambitious, but scalability in quantum computing is a well-known bottleneck. Even with improved error rates, achieving fault tolerance and practical quantum advantage will require years of refinement. For high-risk investors, this means betting on a future that is not yet here.

Conclusion: A High-Risk Bet with High Rewards

Rigetti Computing is a pioneer in quantum computing, with a strong technical foundation and a clear vision for scalable hardware. Its recent advancements in error reduction and multi-chip architectures are impressive, and its cash reserves provide flexibility. However, the company’s declining revenue, reliance on government funding, and the industry’s immature commercial landscape make it a volatile proposition.

For high-risk investors, Rigetti’s stock could be a buy if they are willing to tolerate significant short-term losses in pursuit of long-term gains. The company’s progress in 2025 suggests it is on the right trajectory, but success will depend on its ability to secure commercial partnerships and maintain its technological edge. In a field where the first mover advantage is paramount, timing—and patience—will be everything.
