Honeywell this week formally announced that Quantinuum, still majority-owned by Honeywell, “plans to make a confidential submission of a draft registration statement on Form S-1 to the U.S. Securities and Exchange Commission… relating to the proposed initial public offering of Quantinuum’s common stock.”

This step comes after years of outsider speculation about an IPO that began well before Honeywell confirmed last September after a $600 million fundraising for Quantinuum that the company was in fact on track for an IPO. 

What we still don’t know is when the IPO will happen, how many shares will be offered, or what the price range will be.

It’s looking to be a busy year or so ahead for quantum IPOs. About a week before Honeywell’s announcement on Quantinuum, Infleqtion and special purpose acquisition company (SPAC) Churchill Capital Corp X (CCCX) announced the filing with the SEC of their “joint registration statement on Form S-4” for their proposed merger, which will result in the public stock market debut of Infleqtion. Infleqtion and CCCX had announced their Form S-1 filing back in October 2025, and the pair already has said they are expecting a result of $540 million in gross proceeds. SPAC deals have not always delivered on hopes, however, something that Rigetti Computing experienced back in 2022.

Among others, Xanadu Quantum Technologies and Horizon Quantum Computing both are going the SPAC merger route to becoming publicly-traded firms. Meanwhile, PsiQuantum, QuEra Computing, Classiq, and Pasqal also are being watched closely as potential IPO candidates.
