Two leading quantum computing firms are heading to the public market, but they are taking starkly different routes that reflect the evolving landscape for deep-tech capital raises. Finland’s IQM announced the public filing of its Form F-4 registration to merge with a special-purpose acquisition company, while U.S.-based Quantinuum filed for a traditional initial public offering.
"This filing is a milestone we have worked hard to reach, and it signals our readiness to operate at a new level," Jan Goetz, Chief Executive Officer and Co-Founder of IQM, said. "Public markets will give IQM the platform and capital to accelerate everything we are building as we work towards delivering fault-tolerance quantum computing at scale."
The deal with Real Asset Acquisition Corp. (Nasdaq: RAAQ) gives IQM a pre-money equity valuation of approximately $1.8 billion. Upon closing, IQM intends to list its American Depositary Shares on the Nasdaq under the ticker “IQMX”. The transaction aims to provide IQM with access to up to $175 million in RAAQ’s trust account, $134 million in PIPE financing, and $24 million from warrant exercises, supplementing its $172 million cash balance.
In contrast, Quantinuum, which is majority-owned by Honeywell International, is bucking a trend. The quantum industry has heavily favored SPAC mergers, used by peers like IonQ, D-Wave Quantum, and Infleqtion for faster market access. Quantinuum’s S-1 filing signals its intent to pursue a more conventional IPO, listing on Nasdaq as “QNT.” While financials for the private company are sparse, filings show it remains a research-heavy operation with significant cash burn and a negative free cash flow of $263 million for the trailing twelve months as of March 2026.
A Tale of Two Listings
The divergent strategies highlight a potential shift in investor appetite. The de-SPAC route offers speed, a pre-negotiated valuation, and access to capital, which has been attractive for pre-revenue or early-revenue quantum firms. IQM, which has sold 23 of its full-stack quantum systems, fits this mold. The company’s existing shareholders are not selling shares in the transaction, signaling long-term confidence.
Quantinuum’s IPO path, however, suggests a company confident in its ability to attract public investors on its own merit, supported by the deep pockets and established reputation of its parent, Honeywell. Formed in 2021 from the merger of Honeywell Quantum Solutions and Cambridge Quantum, the company has secured high-profile customers like JPMorgan Chase and Amgen. A traditional IPO, while slower, can offer greater control over pricing and a more stable long-term investor base if market conditions are favorable.
For investors, the upcoming listings provide two new, distinct vehicles to gain exposure to the quantum computing sector. IQM represents a pure-play bet on a European hardware leader scaling its operations, while Quantinuum offers a stake in a U.S. entity with strong corporate backing and a focus on a full-stack solution, including software. The performance of these listings will serve as a critical benchmark for the valuation and future financing of other private companies in the space.
