Quantinuum plans to raise as much as USD$1.05 billion through a Nasdaq initial public offering (IPO), positioning the company for what could become the largest traditional IPO yet for a quantum computing firm. The company updated its SEC filing Tuesday and said it intends to offer about 21 million shares priced between USD$45 and USD$50 each. Additionally, the shares are expected to trade under the ticker QNT on the Nasdaq exchange. At the top of the proposed range, Quantinuum could achieve a fully diluted valuation near USD$12.7 billion, according to Reuters figures referenced in the filing. Furthermore, the IPO would represent one of the most significant public market debuts in the emerging quantum computing sector. Traditional IPOs generally involve stricter regulatory scrutiny than special purpose acquisition company mergers. Consequently, institutional investors often view them as more credible pathways to public markets. Quantinuum emerged in 2021 after Honeywell International Inc. (NASDAQ: HON) merged Honeywell Quantum Solutions with Cambridge Quantum. The transaction combined Honeywell’s trapped-ion quantum hardware with Cambridge Quantum’s software and algorithm business. The updated filing provides investors with one of the clearest financial pictures yet of a major standalone quantum computing company. In addition, it outlines Quantinuum’s revenue growth, operational losses and research ambitions. Quantinuum reported USD$30.9 million in revenue during 2025, compared with USD$23 million one year earlier. Meanwhile, the company generated USD$5.2 million in revenue during the quarter ended March 31, 2026. The company also reported substantial losses as it continued expanding research and development programs. According to the filing, Quantinuum posted a net loss of USD$192.6 million in 2025.
