Quantinuum, a quantum computer developer being carved out of Honeywell, filed on Friday with the SEC to raise up to what we estimate could be $1.5 billion in an initial public offering.
Quantinuum develops quantum computing systems and software with the goal of commercializing quantum technology for enterprise and government applications. The company operates on the premise that future computing will be hybrid in nature, combining classical processors, GPU-based accelerated compute, and quantum processing units to tackle problems that conventional systems cannot efficiently solve. Its work spans hardware development and software, targeting use cases in fields such as artificial intelligence, cybersecurity, drug discovery, and materials science.
The Broomfield, CO-based company was founded in 2021 and booked $36 million in revenue for the 12 months ended March 31, 2026. It plans to list on the Nasdaq under the symbol QNT. Quantinuum filed confidentially on February 17, 2026. J.P. Morgan, Morgan Stanley, Jefferies, Evercore ISI, BofA Securities, UBS Investment Bank, Cantor Fitzgerald, Mizuho Securities, Needham & Co., Societe Generale, and TD Cowen are the joint bookrunners on the deal.
