Quantum computing firm Quantinuum closed up 0.63% in its Nasdaq debut Thursday after raising $1.68 billion in an upsized IPO. The company secured a market value of $15.7 billion.

Shares opened at $68 per share and reached a session high of $71.35 before settling near opening levels. The upsized offering reflects strong investor demand for quantum computing technology. Quantinuum, formed through the merger of Cambridge-based Cambridge Quantum Computing and Quantinuum's predecessor, develops quantum computing hardware and software solutions. The company counts Honeywell International as a major stakeholder. The modest first-day gain positions Quantinuum among recent IPO debuts that opened without significant volatility. The company's $1.68 billion raise places it among the year's larger technology offerings. Quantinuum plans to use IPO proceeds for research and development, infrastructure expansion, and general corporate purposes. The quantum computing sector has attracted significant capital as enterprises explore applications for the emerging technology.
