US quantum computing firm IonQ has raised $372.6 million by selling 16,038,460 shares of its common stock through an “at-the-market” equity offering program (ATM Program).
The company said this allowed it to raise a “sufficient amount” to meet its “currently anticipated capital needs” but has now terminated the ATM Program, citing recent market disruptions and share trading prices.
“We are pleased to have been able to raise over $350 million, even in the recent turbulent markets,” said IonQ CEO Niccolo De Masi. “On a pro-forma basis, this brings our cash balance on December 31, 2024, to over $700 million. We are confident that we now have the capital we need for continued global leadership in both our quantum computing and quantum networking divisions.”
The fundraise comes two weeks after IonQ acquired a majority stake in quantum networking provider ID Quantique, signed a memorandum of understanding with SK Telecom to form a “global quantum strategic partnership,” and appointed de Masi as president and CEO.
The company’s acquisition of ID Quantique marks the second purchase for IonQ in the last six months and the third since 2023. In November 2024, the company announced plans to acquire quantum networking startup Qubitekk for an undisclosed amount, following its purchase of Canadian quantum startup Entangled Networks in January 2023.
As a result of those moves, IonQ said it has a “strong momentum toward its technological roadmap,” with a portfolio of nearly 400 granted and pending quantum networking patents that it owns or controls in both the US and internationally.
IonQ currently operates a manufacturing site and data center in College Park, Maryland, that launched in 2020 and, in January 2025, announced plans to develop a new facility in the state in collaboration with the University of Maryland as part of a project dubbed the “Capital of Quantum” initiative.
The company is also developing a second location outside Seattle in Washington and placing trap ion quantum systems at a site in Basel, Switzerland.
