3 Pre-IPO Quantum Computing Startups Primed for a Meteoric Rise in 2025
Quantum computing isn't just the future—it's the next gold rush. These three stealth-mode startups are building qubit-powered rocketships while Wall Street scrambles to place bets. Here's who's leading the charge.
The Contenders: Who's Solving Real Problems?
Forget 'quantum supremacy' buzzwords—these firms are tackling concrete bottlenecks in drug discovery, financial modeling, and AI training. Their secret? Patent-pending architectures that sidestep error correction nightmares plaguing legacy players.
The IPO Countdown Begins
With Series C rounds closing at unicorn valuations, public listings loom. Early employees are quietly exercising options while VCs whisper about 'the NVIDIA moment' for quantum. (Cue eye rolls from physicists who actually understand decoherence.)
The Bottom Line
Quantum won't replace classical computing—it'll eat its most profitable niches. These startups aren't just chasing academic papers; they're building commercial moats. And when the IPO floodgates open? Expect the usual mix of hype, disappointment, and one or two genuine paradigm shifts. Just follow the institutional money—they've already picked their horses.

is one of the most well-funded quantum startups in the world, having raised more than $1.3 billion. The company is based in the U.S. and focuses on building large-scale, fault-tolerant quantum computers using photonic qubits. Its strategy leans heavily on silicon photonics and deep partnerships with Microsoft (MSFT), NVIDIA (NVDA), and GlobalFoundries (GFS). PsiQuantum aims to build a one-million-qubit machine and has designed its platform for industrial-scale manufacturing. Given its size, focus, and backers, it is widely seen as a top IPO prospect in the sector.
is another standout. Formed by merging Honeywell Quantum Solutions (HON) with Cambridge Quantum, the company uses trapped-ion qubits and offers a full-stack solution, from hardware to enterprise-ready software. It has significant backing from SoftBank (SFTBY)and is considered among the most mature players commercially. Quantinuum has already launched several products and is generating revenue. It remains a top candidate for a public offering, supported by strong institutional partnerships and a growing list of enterprise clients.
, based in France, takes a different approach with neutral-atom quantum computing. The company has raised more than $152 million, with investors including Temasek, the Defense Innovation Fund, and the European Innovation Council Fund. France’s Ministry of Armed Forces also supports PASQAL. It recently opened a factory in Québec and sold a 100-qubit processor to Canada’s Distriq. PASQAL aims to reach 250 qubits by 2026 and scale to 10,000, with an eye on solving real-world problems. It partners with Nvidia and IBM (IBM), and its systems are already running in high-performance computing centers.
Growing Investors’ Interest
All three companies are pushing toward commercialization and expanding global access through cloud platforms, such as Microsoft Azure and Google Cloud (GOOG) (GOOGL). While the timing of any IPO remains unclear, their progress signals a maturing market with growing investor interest.
As publicly traded quantum names like IonQ (IONQ) and Rigetti (RGTI) continue to attract attention but also face volatility, these next-generation private players may offer a stronger foundation when they do enter the public market. Investors looking for the next big leap in tech may want to keep them on the radar.
