Infleqtion has officially stepped onto the public stage, beginning trading on the New York Stock Exchange under the ticker INFQ following the completion of its previously announced business combination with Churchill Capital Corp X. The listing marks a major milestone not just for the company itself, but for the neutral-atom approach to quantum computing and sensing, which Infleqtion has been quietly pushing from laboratory promise into deployed systems used by governments and industry. The transaction drew unusually strong shareholder support, resulting in more than 550 million dollars in gross proceeds, including nearly all of the cash held in Churchill X’s trust account and over 125 million dollars raised through a PIPE involving both existing Infleqtion backers and new institutional investors. That kind of capital vote is hard to ignore, even by SPAC-weary markets.
Infleqtion’s leadership has been clear about what this moment represents. According to CEO Matthew Kinsella, the company was built around a straightforward conviction: neutral atoms offer the most scalable and economical route to commercial quantum technologies. That architectural choice, paired with a vertically integrated stack spanning hardware and software across quantum computing and quantum sensing, has already translated into real traction. Becoming a public company is less about celebration and more about acceleration, giving Infleqtion the ability to move faster on its technology roadmap and to scale deployments in aerospace, defense, and critical infrastructure, areas where quantum advantage is no longer theoretical but operationally relevant.
What sets Infleqtion apart is the breadth of its product portfolio and how intentionally it has been engineered for use outside pristine lab conditions. The company develops quantum computers, quantum optical clocks, RF receivers, and inertial sensors, all optimized through proprietary software and designed for field deployment. These systems are already in use by the U.S. Department of War, NASA, and the U.K. government, and they form part of several collaborations with NVIDIA, a signal that Infleqtion is positioning itself within the broader high-performance and AI-adjacent computing ecosystem rather than treating quantum as an isolated island.
Recent announcements underline how wide that positioning has become. In space, Infleqtion is working with NASA on a mission supported by more than 20 million dollars in contracted funding to fly the world’s first quantum gravity sensor, a step that could redefine precision measurement in orbit. The company has also partnered with Voyager Technologies to advance dual-use quantum capabilities in low-Earth orbit and beyond. On the national security front, a 2 million dollar contract from the U.S. Army focuses on resilient navigation and timing in contested environments, a problem that traditional GPS-dependent systems struggle to solve. Meanwhile, in critical infrastructure, Infleqtion is executing its role in the U.S. Department of Energy’s 6.2 million dollar ARPA-E ENCODE program, applying quantum computing techniques to energy grid optimization, an unglamorous but deeply consequential application.
To mark the transition from private innovator to public company, Infleqtion will ring the opening bell at the New York Stock Exchange on Wednesday, February 18. It’s a symbolic gesture, sure, but also a very visible signal that neutral-atom quantum technology has moved into a new phase, one where deployment, contracts, and revenue matter as much as qubits and coherence times. The bell will ring once, but the expectation now is sustained execution, and the market will be watching closely.
