Stock pick: Rigetti Computing, Inc. (RGTI), listed on Nasdaq.
Portfolio: Quantum Portfolio. This pick is intended to add a gate-based superconducting quantum computing exposure alongside the portfolio’s existing D-Wave Quantum position, rather than duplicate the annealing-focused risk profile already represented by QBTS.
Why Rigetti Fits the Quantum Portfolio
Rigetti is one of the few publicly listed, reasonably liquid pure-play quantum computing companies still within the portfolio’s preferred small-cap to lower mid-cap market-cap range. The company is focused on superconducting quantum processors, full-stack quantum-classical infrastructure, cloud access through Rigetti Quantum Cloud Services, and on-premises quantum systems for research, government, and enterprise customers.
The risk-adjusted appeal is not that Rigetti is already a profitable quantum computing business; it is not. The appeal is that the company now combines a major product milestone, early revenue growth, a large cash position, and a cleaner balance sheet with several visible catalysts over the next six to twelve months.
Core Investment Thesis
Rigetti’s 108-qubit Cepheus-1-108Q system reached general availability in April 2026 across Rigetti QCS, Amazon Braket, Microsoft Azure Quantum, and qBraid, giving investors a near-term technical and commercial validation point. In Q1 2026, revenue increased to $4.4 million from $1.5 million in the prior-year period, helped by on-premises Novera QPU sales and customer deployments.
The balance sheet is a key part of the thesis. Rigetti reported $569.0 million of cash, cash equivalents, and available-for-sale investments as of March 31, 2026, and stated that it ended the quarter with no debt. That cash runway matters because quantum hardware remains capital intensive and commercial adoption is still early.
12-Month Catalysts
- 108-qubit system adoption: Customer usage of Cepheus-1-108Q through major cloud platforms could improve the credibility of Rigetti’s chiplet-based scaling strategy.
- On-premises QPU deliveries: Additional Novera or Cepheus system shipments to academic, government, and national lab customers could support revenue growth from a small base.
- Technology milestones: Further fidelity gains, faster gate speeds, and evidence that chiplet-based architecture can scale without unacceptable error-rate degradation would be meaningful rerating triggers.
- International expansion: Rigetti’s stated plan to invest in the United Kingdom and deploy a UK-based system with more than 1,000 qubits over the next three to four years creates a longer-duration catalyst pipeline.
- Government and strategic demand: Quantum computing remains strategically important for national security, advanced research, AI, materials science, and cryptography, which could support contract opportunities if Rigetti executes.
Valuation View
RGTI is not conventionally cheap. The stock trades at a speculative multi-billion-dollar valuation despite quarterly revenue that remains very small, so the setup depends on continued technical progress and the market’s willingness to capitalize future quantum optionality. However, compared with larger quantum peers that have already moved well beyond the portfolio’s preferred market-cap range, Rigetti offers a cleaner small-to-mid-cap pure-play vehicle with stronger upside sensitivity to execution wins.
Balance Sheet and Survivability
Rigetti’s reported $569.0 million liquidity position and no-debt status provide meaningful survivability for a deep-tech company still generating operating losses. The company also stated in its Q1 2026 Form 10-Q that existing cash, cash equivalents, and available-for-sale investments should be sufficient to meet anticipated operating cash needs for at least the next twelve months, based on its current business plan.
Key Risks
- Technology execution risk: Scaling superconducting quantum systems while maintaining high fidelity is difficult, and commercial quantum advantage remains uncertain and may take longer than investors expect.
- Valuation and dilution risk: The valuation already discounts substantial future success. If revenue remains lumpy, milestones slip, or capital needs rise, the stock could re-rate sharply lower or face future dilution.
Bottom Line
Rigetti is a high-risk, high-upside quantum computing pick, but it improves the Quantum Portfolio’s diversification because it adds superconducting gate-based hardware exposure rather than another annealing-focused company. The next six months should provide useful evidence on whether the 108-qubit platform, on-premises demand, and fidelity roadmap can convert investor excitement into measurable business momentum.
