Upcoming Quantum IPOs to Watch

Infleqtion (Ticker: INFQ)

Infleqtion, a Boulder-based specialist in neutral-atom quantum computers and high-precision sensors, will merge with Churchill Capital Corp X (CCCX) in a SPAC transaction valuing the firm at $1.8 billion and raising $540 million before deal expenses. Proceeds will accelerate product development in AI, defense, and aerospace sensing. Trading is expected to commence under “INFQ” by late 2025 or early 2026.

PsiQuantum (Pre-IPO, Photonic Qubits)

With over $1.3 billion in funding, PsiQuantum aims to build a one-million-qubit photonic quantum computer leveraging silicon photonics and partnerships with Microsoft, NVIDIA, and GlobalFoundries. Its industrial-scale manufacturing roadmap and deep-pocketed backers make it a top contender for a 2026 public offering.

Quantinuum (Pre-IPO, Trapped-Ion)

Formed by the merger of Honeywell Quantum Solutions and Cambridge Quantum, Quantinuum offers a full-stack trapped-ion platform and is generating revenue from enterprise and government clients. Significant SoftBank backing and a mature commercial roadmap position it for an imminent IPO.

PASQAL (Pre-IPO, Neutral-Atom)

France’s PASQAL has raised €152 million to date, backed by Temasek, the European Innovation Council, and France’s Ministry of Armed Forces. Its neutral-atom architecture targets mid-scale, fault-tolerant quantum computers and quantum simulation services. A European listing in late 2025 is widely anticipated.

Horizon Quantum Computing will merge with dMY Squared (NYSE: DMYY) in a deal slated to close in Q1 2026. The transaction expands SPAC pipelines and will deliver access to Horizon’s neutral-atom qubit technology and QaaS platform, with post-merger equity valued near $1 billion.

Key Takeaways:

• SPAC listings (Infleqtion, Horizon) offer immediate public-market access and sizeable capital infusions.
• Photonic (PsiQuantum) and trapped-ion (Quantinuum) pioneers are nearing IPO readiness, backed by strong venture and corporate investors.
• Neutral-atom innovators (Infleqtion, PASQAL, Horizon) promise both computing and sensing applications, broadening commercialization pathways. Investors should evaluate technology maturity, cash runway, and listing structure when positioning portfolios.
