Quantinuum, the quantum computing company majority-owned by Honeywell International, is one of the most promising candidates in the industry. Investors may get a chance to buy in soon.
Quantinuum is gearing up to submit a draft registration statement to the Securities and Exchange Commission for a proposed initial public offering, Honeywell said on Wednesday. The number of shares and price range for the proposed offering have yet to be determined.
Barron's was the first to report on Quantinuum's prospective IPO last year after a source with direct knowledge of the matter indicated Honeywell planned to take the company public sometime between 2026 and 2027.
The company was founded in 2021 through the merger of Honeywell Quantum Solutions and Cambridge Quantum, a U.K.-based start-up. That makes it a fairly new entrant into the space versus peers like D-Wave Quantum that have been operating commercially for years.
The initial preparations for an IPO follow a big year for Quantinuum. The company unveiled its latest system, Helios, in November 2025, with CEO Rajeeb Hazra describing it as "the world's most accurate quantum computer."
Honeywell stock rose 2.2% following Wednesday's announcement. Futures tracking the tech-heavy Nasdaq Composite were down 0.5%.
