Quantinuum: $1.05 Billion IPO Filed For Quantum Computing Expansion - Pulse 2.0
Summarize this article with:
Quantinuum, a quantum computing company backed by Honeywell International, has filed for a US initial public offering seeking to raise up to $1.05 billion as investor enthusiasm around quantum computing continues to grow. The company plans to offer approximately 21 million shares priced between $45 and $50 per share, according to a filing with the US Securities and Exchange Commission. At the top end of the range, Quantinuum would command a market valuation of approximately $12.7 billion based on outstanding shares listed in the filing. Founded in 2021 through the merger of Honeywell Quantum Solutions and Cambridge Quantum, Quantinuum develops quantum computing systems designed to solve highly complex computational problems beyond the capabilities of traditional computers. The company is targeting applications across chemistry, machine learning, cybersecurity, finance, and drug discovery. Quantinuum said companies including Amgen and Mitsui & Co. are among its early users and collaborators. “We believe that we are executing a roadmap to the first commercial-scale, fully fault-tolerant quantum computer before the end of this decade, the Apollo system,” CEO Rajeeb Hazra wrote in a letter to investors included in the filing. The company reported a net loss of $136.6 million on revenue of $5.2 million for the quarter ended March 31, compared with a net loss of $30.5 million on revenue of $19.1 million during the same period a year earlier. Investor interest in quantum computing has accelerated alongside the broader artificial intelligence boom. Shares of D-Wave Quantum have surged more than 200% in 2025 after gaining over 800% the prior year, while Rigetti Computing previously climbed nearly 3,000% between early 2023 and the end of 2025 before retreating from peak levels. The Trump administration recently announced more than $2 billion in funding for US quantum computing firms. Quantinuum is expected to receive $100 million under the initiative, while IBM is slated to receive $1 billion, the largest allocation in the Commerce Department package. The US government will receive minority, non-controlling equity stakes in participating companies in exchange for the funding. Following the IPO, Honeywell is expected to retain approximately 49% voting control in Quantinuum, while Cambridge Quantum is expected to hold roughly 33% of the voting power. Quantinuum disclosed several risks in its filing, including the need to scale manufacturing processes for higher-volume quantum computer production and dependence on single-source suppliers for key materials and systems. The company currently operates four commercial quantum computing systems, with three at its Broomfield, Colorado, campus and one in Japan. A fifth system is expected to be deployed in Singapore later this year. JPMorgan Chase and Morgan Stanley are leading the offering, which is expected to price on June 3. Quantinuum plans to trade on the Nasdaq Global Market under the ticker symbol QNT.
