In August 2025, Rigetti Computing (RGTI) stock peaked investors’ interest with its 36-qubit quantum system launch, yet the company still faces profitability doubts despite its ambitious 1,000-qubit roadmap, putting a damper on the Rigetti Computing stock forecast.
The $250 million Quanta Computer partnership could scale modular chips for cloud platforms, but with sales minimal and losses mounting, Cantor Fitzgerald’s $15 price target per stock highlights high risk.
Currently, giants like Google and IBM lead in qubit scale and error reduction, leaving pure plays like Rigetti Computing in speculative territory.
Interest in Rigetti Computing RGTI stock forecast 2025 is gaining more momentum as the quantum race is heating up.
Following the Rigetti Computing stock price prediction hype, investors’ focus turns to its roadmap of a 36-qubit system preceding a 100+ qubit build by year-end and a 1,000-qubit goals in four years.
Even if this is fueling optimism for momentum, translating it into potential profit remains the true test for the California-based company.
Quantum Computing Investment Opportunities 2025
Rigetti’s chiplet-based architecture is fueling its growth. From the recent launch of the 36-qubit Cepheus‑1 system to plans for 1,000 qubits in the next few years. A $250 million production partnership with Quanta Computer aims to scale systems and embed them into hybrid cloud platforms.
Combined with in-house chip fabrication and proprietary calibration tools, this positions well for long-term gains, a key part of its Rigetti computing stock forecast.
Among other investor eagerness, leading quantum computing stocks offer stable opportunities, while some thrill-seekers explore quantum computing penny stocks for speculative possibilities. But at nearly 500 times trailing sales, the question on everyone’s mind remains: is RGTI a good stock to buy today?
What Are the Best Quantum Computing Stocks for 2025?
A range of studies highlights both technology giants and specialist quantum vendors pushing the market ahead:
- Alphabet (Google) impressed with its Willow processor, a 105-qubit machine that reduces errors by orders of magnitude, reflecting its increasing leadership in the quantum arena.
- IBM is doubling down on hybrid-cloud quantum services and is targeting a 1,000-qubit computer sometime in 2026.
- IonQ is a trapped-ion system leader, available on all cloud platforms, with strong revenue growth ahead, one of the top undervalued stocks right now.
- D-Wave focuses on quantum annealing for optimization use cases and shows growing commercial traction.
Here, Best Quantum Computing Stocks to buy for 2025, including Rigetti, highlight its modular superconducting advantage and sky-high potential. But with no obvious commercial traction, it remains in speculative penny quantum computing stocks land despite the engineering wins.
Cantor Fitzgerald’s analyst also started a $15 price target on Rigetti, based on its Deep‑chip strategy and Quanta agreement, versus $45 for IonQ, highlighting the invest in quantum computing stocks carefully, weighing long-term upside and near-term risk.
In short, quantum computing investment opportunities in 2025 do exist, but the sector is still in its early stages. Pure plays like Rigetti offer high reward with high risk, even if diversification is advisable, and cautious optimism remains the right attitude for now.
