Quantinuum: $1.05 Billion IPO Filed For Quantum Computing Expansion - Pulse 2.0
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
