Honeywell, in a long-anticipated move, announced that Quantinuum “confidentially submitted a draft registration statement on Form S-1” to the SEC more than two months ago regarding a proposed IPO.

A very brief press release stated that the filing occurred on Feb. 17, which means it happened about one month after Honeywell first said that it planned to file the IPO documents–though it didn’t say at that time how soon it would do so. 

Quantinuum is still majority-owned by Honeywell, but speculation about a possible IPO has been circulating for years, and really started to pick up steam after Honeywell in early 2025 announced a plan to restructure and spin off its largest businesses into three separate companies.

There are still virtually no further details available on the Quantinuum IPO plan, including when it will happen, how many shares will be offered, and how they will be priced.

It’s only April, but it already has been a big year for stock market debuts by pure-play quantum technology firms. Infleqtion closed its SPAC merger and went public in February, Horizon Quantum Computing followed barely a month later, and Xanadu Quantum Computing debuted just days after Horizon. Other companies which this year (Again, it’s only April…) have announced plans to go public via SPAC deals include Finland’s IQM Quantum Computers and France’s Pasqal. 

Three stock market debuts, likely at least three more to come in 2026. And, quantum stocks have been on the rise again lately, in particular since Nvidia last week announced new quantum AI models designed to help streamline quantum processor calibration and quantum error correction. 

That news lifted a bunch of quantum stocks, but none surged more than Xanadu’s, which as of April 22 is up well over 100% since the Nvidia announcement. What’s wacky about that is Xanadu was not among the several quantum organizations name-checked in Nvidia’s announcement, though it is a longtime Nvidia partner. The boost has made a billionaire of Xanadu founder Christian Weedbrook. Nice windfall, but he still has to deal with the media trying to keep him modest by mentioning in numerous stories this week that Weedbrook was a film school dropout.

We’ll see how long all this stock market fun lasts…
