Quantinuum Inc. completed its initial public offering by selling 28 million shares of Class A common stock at $60 per share, the company said. The transaction produced gross proceeds of $1.68 billion before accounting for underwriting discounts and other offering-related expenses.
Following the offering, Quantinuum's Class A shares began trading on the Nasdaq Global Market under the ticker symbol "QNT." The Securities and Exchange Commission declared the company's registration statement effective on June 3, 2026, clearing the way for the issuance and listing.
Investment banks leading the deal included J.P. Morgan and Morgan Stanley, which served as joint lead active book-running managers. Jefferies and Evercore ISI were named additional active book-running managers. A broader syndicate of joint book-running managers comprised BofA Securities, UBS Investment Bank, Cantor, Mizuho, Needham & Company, Societe Generale and TD Cowen, while Craig-Hallum and Rosenblatt acted as co-managers.
Quantinuum describes its technology offering as centered on the QCCD architecture. The company maintains operations across a number of countries and regions, with facilities in the United States, United Kingdom, Germany, Japan, Qatar and Singapore. Corporate headquarters are in Broomfield, Colorado.
According to the company's press statement, its customer base spans several sectors, including pharmaceuticals, material science, financial services, and government and industrial markets. The IPO establishes public equity access for the company while the statement notes the proceeds figure before deductions for underwriting and other expenses.
The information released with the offering details the institutional and syndicate structure that supported the sale of the Class A shares and confirms the SEC's effectiveness determination that enabled Quantinuum to commence trading on Nasdaq. The press material provides no additional detail on net proceeds after fees or on post-listing market performance.
Context and next steps
The filing and listing mark a transition point for Quantinuum from private to public ownership of its Class A stock, with market trading now under the QNT ticker. The company will now operate as a publicly traded entity while continuing its stated focus on quantum computing systems built on the QCCD architecture and serving clients across multiple industry verticals.
