Infleqtion, a developer of neutral-atom quantum technology, began trading on the New York Stock Exchange (NYSE) today under the ticker symbol “INFQ.” The public listing follows the completion of a business combination with Churchill Capital Corp X, a special purpose acquisition company (SPAC). This milestone makes Infleqtion the first neutral-atom quantum hardware and sensing company to enter the public markets.
The transaction provided Infleqtion with over $550 million in gross proceeds. This capital includes a $125 million common stock Private Investment in Public Equity (PIPE) from institutional investors and nearly 100% of the cash held in Churchill X’s trust account, representing a high retention rate of the original SPAC capital. The company intends to use the funding to accelerate its technology roadmap and expand the deployment of practical quantum solutions across aerospace, defense, and critical infrastructure.
Infleqtion utilizes a vertically integrated stack that combines neutral-atom hardware with its proprietary Superstaq software platform. The company’s architecture supports both quantum computing and high-precision quantum sensing. According to CEO Matthew Kinsella, the neutral-atom approach was selected for its inherent scalability and economic advantages in real-world environments compared to other quantum modalities.
The company currently manages a diverse portfolio of government and commercial contracts. Key projects include a $20 million mission with NASA to fly a quantum gravity sensor in space and a collaboration with NVIDIA that yielded a demonstration of a materials science application using logical qubits. Other active engagements include a contract with the U.S. Army for resilient navigation and timing data, and a $6.2 million project under the U.S. Department of Energy’s ARPA-E ENCODE program focused on energy grid optimization.
Beyond quantum computing, Infleqtion’s hardware range includes quantum optical clocks, RF receivers, and inertial sensors. With operational footprints in the U.S., Europe, and Asia, the company serves a customer base across the space, energy, finance, and telecommunications sectors. Infleqtion executives will celebrate the listing by ringing the opening bell at the NYSE on February 18, 2026.
