Broomfield-based quantum computing company Quantinuum has taken the first official step toward becoming a standalone public company, its majority owner, Honeywell, announced Wednesday.
The industrial giant filed a confidential draft registration with the SEC for an Initial Public Offering (IPO) of Quantinuum’s common stock. While the number of shares and the expected price have not yet been set, the move signals a major shift in the quantum computing landscape.
The decision to go public follows a year of rapid technical milestones for the Broomfield, Colorado-based company. In late 2025, Quantinuum launched Helios, its third-generation quantum computer.
Helios represents a significant leap forward, featuring 98 physical qubits and, more importantly, a high ratio of logical qubits—stable, error-corrected units of information that are essential for solving real-world problems. The company also recently demonstrated “quantum information supremacy” in partnership with UT Austin, proving their hardware can handle tasks that would require impossible amounts of memory on a traditional supercomputer.
Investors are watching closely. Just last year, Quantinuum raised $600 million in a funding round led by JPMorgan Chase, Mitsui & Co., and Nvidia, valuing the company at $10 billion. Some analysts suggest that a public offering could push that valuation even higher as demand for “quantum-ready” technology grows in sectors like drug discovery, finance, and cybersecurity.
Because the filing is “confidential,” the public won’t see Quantinuum’s detailed financial health for several months. The IPO is expected to hit the market later in 2026, pending review by the SEC and favorable market conditions.
