Quantinuum, a quantum computing firm backed by Honeywell International Inc. and other investors, is considering raising funds at a valuation of approximately $10 billion, nearly doubling its previous $5 billion valuation. The fundraising talks involve both current and new backers, with potential capital injections in the hundreds of millions of dollars. Nvidia has been approached as a potential investor in this round. Separately, Honeywell has filed a Form 10 registration statement for the spin-off of its Solstice Advanced Materials unit, which is planned to become a standalone public company in the fourth quarter of 2025. An investor day is scheduled for October 8, 2025, to discuss the spin-off, which is part of Honeywell's strategy to unlock value and focus on core operations. Additionally, Quantinuum has recently expanded its quantum software stack by launching new open-source software tools, Guppy and Selene, to support its quantum computing development.
