Quantinuum Inc., a quantum computing company backed by Honeywell International Inc., has increased the size of its initial public offering. According to an SEC filing, the firm will sell 26.5 million shares at $53 to $55 apiece, aiming to raise up to $1.46 billion at a valuation of up to $14.3 billion.
The upsizing signals strong demand for a sector still in its commercial infancy. Few quantum firms have reached the public markets, making this one of the larger tech IPOs of the year. Honeywell, which holds a majority stake, stands to gain substantially from the listing.
Pricing details place Quantinuum's market cap well above peers. The company is offering roughly 26.5 million shares, with the final price range set between $53 and $55. At the high end, proceeds could total $1.46 billion, according to the filing.
Success here could pave the way for other quantum startups to go public. Investors are betting that quantum computing will eventually disrupt industries from pharmaceuticals to finance, though near-term revenue remains limited. The IPO's performance will be closely watched as a bellwether.
Some analysts caution that the valuation may be premature given the technology's long development timeline. "Quantum computing has enormous potential, but commercial scalability is still years away," one research note warned.
