This figure represented an impressive 222% year-over-year increase, showcasing continued operational momentum. The company attributed this growth to expanding demand for its quantum solutions and newly integrated technologies.
IonQ raised its full-year revenue expectations to $110 million at the high end of guidance. The company maintained a disciplined cost structure while scaling commercial operations across research and industrial sectors. As a result, IonQ demonstrated its ability to convert technical progress into meaningful financial results.
IonQ also reported a net loss of $1.1 billion for the quarter, reflecting ongoing investment in innovation and infrastructure. Adjusted EBITDA loss totaled $48.9 million, while Adjusted EPS stood at ($0.17). Despite near-term losses, the firm’s strong top-line growth and liquidity position pointed to long-term resilience.
Achieves Historic Quantum Performance and Technical Milestones
IonQ reached a world-record 99.99% two-qubit gate fidelity, setting a new benchmark in quantum hardware performance. This breakthrough marked a key step toward full fault-tolerant quantum computing and commercial scalability. The company also completed the 2025 technical milestone of #AQ 64 three months ahead of schedule.
Achieving #AQ 64 unlocked computational power estimated to be 36 quadrillion times greater than leading superconducting systems. The milestone showcased IonQ’s leadership in quantum processing capability and precision engineering. Through continuous innovation, IonQ has positioned itself as the world’s most advanced quantum platform.
The firm further accelerated development with the acquisitions of Oxford Ionics and Vector Atomic. These strategic additions enhanced IonQ’s full-stack quantum platform, integrating control systems, atomic precision, and new application areas. The company emphasized that such vertical integration supports long-term scaling and product differentiation.
Expands Partnerships and Strengthens Financial Position
IonQ signed a new contract with Oak Ridge National Laboratory to develop advanced energy applications. The collaboration aims to accelerate quantum-classical workflows in scientific computing and energy modeling. This partnership reflected IonQ’s expanding role in enabling national-scale quantum programs.
As of September 30, 2025, IonQ reported $1.5 billion in cash and investments. Following a $2 billion equity offering in October, its pro-forma cash rose to $3.5 billion. The strengthened capital base provided resources to fund expansion, enhance R&D, and extend market reach globally.
With a robust financial position and strong technology roadmap, IonQ reinforced its dominance in the quantum sector. The company continues to build momentum through early technical achievements and expanding commercial adoption. IonQ’s surging stock reflected growing confidence in its trajectory toward large-scale quantum computing leadership.
