The quantum computing revolution promises to solve previously impossible computational problems, potentially transforming everything from drug discovery to financial modeling. As investors seek exposure to this emerging technology, Rigetti Computing (NASDAQ: RGTI) has emerged as a compelling but highly speculative option. The Berkeley-based quantum computer maker has seen its stock surge an astronomical 1,860% over the past six months, fueled by a marketwide uptick in all things quantum.
The company stands at the forefront of developing practical quantum computers using superconducting qubits. These quantum bits operate at extremely low temperatures and leverage existing semiconductor manufacturing techniques. But with a market capitalization of $5.33 billion against minimal revenue, investors need to carefully evaluate if the current valuation is justified.
Let’s analyze the company’s technology advantages, financial position, and market opportunity to determine if this high-flying stock still offers value in 2025.
Rigetti’s latest 84-qubit Ankaa-3 system showcases the company’s technological progress. The system achieves 99.5% median 2-qubit gate fidelity — a critical performance metric that measures how accurately the quantum computer performs operations. This advancement stems from a novel chip fabrication technique called alternating-bias assisted annealing, or ABAA for short, which enables precise control over qubit frequencies.
The company’s modular chip architecture represents another key advantage. Rather than pursuing a single large processor, Rigetti connects smaller chips. This approach recently demonstrated success, with 9-qubit chips achieving 99.4% fidelity even when connected. The company plans to leverage this technology to create a 36-qubit system using four connected chips by mid-2025, followed by a 100-plus qubit system later in the year.
Rigetti’s financial position was significantly boosted by a capital raise last November. Specifically, the company secured $100 million, before deducting commissions and other offering expenses, through a direct offering of 50 million shares to institutional investors at $2.00 per share. When combined with existing cash and investments of $92.6 million, management believes it has sufficient capital to execute its near-term quantum computing roadmap without needing additional fundraising.
Yet even with strengthened finances, Rigetti trades at a staggering 260 times trailing sales — a valuation that assumes the company will capture substantial market share as quantum computing matures. While this revolutionary technology could generate trillions in economic value, most experts believe practical, revenue-generating applications remain years away, likely not emerging until the 2030s.
The competitive landscape poses additional challenges. Tech giants Alphabet and IBM bring vastly superior resources to their quantum computing efforts, while numerous well-funded start-ups vie for leadership in this nascent field. With annual revenue projected at under $16 million this year and substantial ongoing losses, Rigetti faces an uphill battle against these formidable competitors.
Rigetti’s partnership strategy provides some validation of its approach. Tech giants Amazon and Microsoft will make the Ankaa-3 system available through their cloud platforms Amazon Braket and Azure in the first quarter of 2025. This could significantly expand access to Rigetti’s technology while providing valuable revenue streams to support its build-out.
Furthermore, the company collaborates with Riverlane on quantum error correction — a critical capability for building practical quantum computers. Their recent demonstration of real-time, low-latency error correction on the Ankaa-2 system represents important progress toward fault-tolerant quantum computing.
Rigetti combines genuine technological breakthroughs with a clear roadmap for scaling its quantum computers. The modular chip architecture and novel fabrication techniques provide credible paths toward more powerful systems. Once the technology matures, strategic partnerships with major cloud providers could accelerate commercialization.
The recent $100 million capital raise significantly reduces near-term funding risk. However, the current valuation prices in tremendous execution with little margin for error. While quarterly revenue remains modest and operating losses substantial, investors must weigh the revolutionary potential of quantum computing against the very real possibilities of technical setbacks, increasing competition, or slower-than-expected commercial adoption.
For investors convinced of quantum computing’s transformative potential, Rigetti offers direct exposure to a potential industry leader. But given the astronomical valuation and significant uncertainties, any position should be sized as a speculative bet rather than a core holding. The quantum computing revolution may be approaching, but picking long-term winners at this early stage requires both deep conviction and careful risk management.
