Quantinuum will file for an initial public offering.
The quantum computing company will confidentially file its S-1 with the Securities and Exchange Commission to offer shares. Honeywell, majority owner of Quantinuum, announced the IPO in a statement.
Details about the offering are sparse. The number of shares, price range and financial disclosures will come at a later date.
Quantinuum will likely be the most high profile quantum computing player to launch an IPO. Quantum companies had a banner year in 2025 raising funds via secondary stock offerings.
The company is valued at $10 billion following its latest venture round. Quantinuum also launched its Helios quantum computing and enterprise customers.

- Quantinuum valued at $10 billion after $600 million venture round
- Quantinuum fleshes out quantum software stack with open source Guppy, Selene
One thing worth watching is whether the Quantinuum IPO sucks capital flows away from the current publicly traded field, which is led by IBM, IonQ, D-Wave, Rigetti and others. In addition, Infleqtion is planning to go public via a SPAC merger with Churchill Capital Corp X under the ticker INFQ.
