MW Looking for a new quantum stock? Honeywell plans an IPO of its Quantinuum business.
By Tomi Kilgore
Honeywell, which owns a majority of the quantum-computing business, intends to confidentially file an S-1 draft registration statement
Honeywell said it plans a confidential filing with the SEC aimed at taking Quantinuum, its quantum-computing business, public.
Shares of Honeywell climbed toward a six-month high Wednesday after the conglomerate known for its aerospace and building-products businesses said it plans to take its quantum-computing business public.
An initial public offering of Quantinuum, in which Honeywell $(HON)$ is a majority owner, comes as the company is in the midst of a breakup of its conglomerate structure, amid criticism that shareholders would be better served with the company's management focusing on its core business. Honeywell spun off its advanced-materials business, Solstice Advanced Materials $(SOLS)$, in October and is planning to separate its aerospace-technologies business in the second half of 2026.
Solstice is a play on the hot artificial-intelligence and nuclear-power sectors. And now Honeywell is looking to spin off Quantinuum to the public at a time when investors have been clamoring for quantum-computing stocks.
Honeywell's stock rose 1.4% in recent morning trading, to the highest level seen since July.
Among quantum stocks already available to investors, D-Wave Quantum shares (QBTS) have rocketed 494.4% over the past 12 months, while Rigetti Computing's stock (RGTI) has soared 169.1% and IonQ shares $(IONQ)$ have rallied 62.5%. The Defiance Quantum exchange-traded fund QTUM has gained 48% over the past year.

Honeywell said it plans to confidentially file a Form S-1 registration statement to the U.S. Securities and Exchange Commission. With that, investors will get a first look at details about Quantinuum's business, including financials, business plans and risks to investors.
The number of shares that would be offered to the public and the expected price range, which would determine the market value of Quantinuum, have not yet been decided.
The plan to go public comes as investor interest in IPOs has been recovering from weakness seen in late 2025, as the broader stock market took a hit in November. The Renaissance IPO ETF IPO has gained 5.4% in January but has lost 2.3% over the past three months. Over the past 12 months, the ETF has gained 9.5%, while the S&P 500 index SPX has advanced 18.6%.
