Quantum Computing Inc. (QCi) has entered into securities purchase agreements for the purchase and sale of 37,183,937 shares of common stock in an oversubscribed private placement, expected to total $750 million.

The shares are priced at the market under Nasdaq rules, with the offering expected to occur on or about October 8, 2025, subject to customary closing conditions.

Founded in 2018, QCi delivers full-stack quantum solutions, specializing in photonic quantum computing systems. The company also fabricates photonic computing engines using thin-film lithium niobate (TFLN) and other transition metal ferroelectrics at its fab in Tempe, Arizona.

The company said it intends to use the proceeds from the sale to fund the commercialization of its technology, support its efforts to explore acquisitions, establish volume production capabilities, and increase the size of its sales and engineering teams.

Titan Partners Group, a division of American Capital Partners, is acting as the sole placement agent for the offering.

“Total capital raised since November 2024 is now $1.64 billion, positioning QCi with the strongest balance sheet among publicly traded quantum computing companies and providing what we believe is sufficient funding to execute our current business plan through 2028,” said Dr. Yuping Huang, CEO and chairman of the board of QCi.

“The support from our existing investors through this recent raise is validation of our vision, technology, and roadmap. Our focus now shifts to expedite the transition from a quantum technology innovation company to a leading quantum hardware manufacturer, progressing our mission of putting quantum into the hands of people.”
