Key Points

- Quantum computing companies are quietly entering public markets.

- Infleqtion, Horizon Quantum, and Xanadu are pursuing different strategies to advance quantum computing.

- While these companies are still risky investments, they could benefit if quantum technology sees broader commercial adoption over the next decade.

SpaceX is one of the most anticipated potential initial public offerings (IPOs) on Wall Street. Recent reports suggest SpaceX could seek a valuation of as much as $1.75 trillion, driven largely by the rapid growth of its Starlink satellite internet business and reusable rocket systems.

However, the quantum computing industry is also producing new public companies, giving investors new ways to gain exposure to the long-term potential of this emerging technology.

1. Infleqtion

Infleqtion (NYSE: INFQ) became a public company in February 2026 through a special purpose acquisition company (SPAC) merger with Churchill Capital Corp X. The company raised more than $550 million in new funding to strengthen its balance sheet and support future growth across quantum computing.

Infleqtion is focused on neutral-atom quantum computing technology, which avoids the use of massive ultra-cold cooling systems used by some competing quantum computing approaches. The company also develops quantum technologies across sensing, networking, atomic clocks, and navigation systems, which gives it exposure to multiple potential quantum markets beyond just quantum computing.

The company is already generating revenue largely from government and defense clients. The company reported revenue of $32.5 million in fiscal 2025 and expects revenue of around $40 million in fiscal 2026.

Infleqtion recently delivered the United Kingdom's first operational 100-qubit neutral-atom quantum system to the National Quantum Computing Centre. The company aims to build quantum computing systems with more than 30 logical qubits (more stable units of quantum information than physical qubits) by 2026 and more than 100 logical qubits by 2028.

Infleqtion has also built relationships across U.S. government programs, including projects tied to Defense Advanced Research Projects Agency (DARPA), NASA, and the U.S. Navy. Furthermore, it is working with Nvidia to integrate its quantum computing systems into AI-powered supercomputing environments to support hybrid quantum workloads.

Infleqtion is a risky investment and is still recording losses. However, its growing government relationships, expanding commercial quantum technology portfolio, and improving balance sheet could position the company as an attractive quantum computing pick for long-term investors.

2. Horizon Quantum Computing

Horizon Quantum (NASDAQ: HQ) also went public through a SPAC merger with dMY Squared Technology Group. The transaction added roughly $120 million in gross proceeds to the company's balance sheet, helping it continue developing its quantum software platform.

While the majority of publicly traded quantum companies are focused on building quantum hardware, Horizon is focused on developing programming tools to help developers write quantum applications that can run across different types of quantum computers. The company's Triple Alpha platform is designed to support multiple types of quantum computers, while Horizon is also developing a programming language called Beryllium to make quantum software development more accessible to users who are not quantum hardware specialists.

Horizon has also started building its own hardware systems to help test and improve its quantum software platform. The company recently completed Ember One, an in-house quantum system at its Singapore headquarters built using Rigetti Computing's Novera quantum processor. Horizon has also entered an agreement to purchase one of IonQ's first 256-qubit quantum systems.

Horizon reported no revenue and an operating loss of $6.5 million in the first quarter of fiscal 2026. However, if quantum computing eventually becomes commercially useful at scale, Horizon could emerge as an important software infrastructure player within the broader quantum computing ecosystem.
