Quantinuum (NYSE: QMUM) priced its initial public offering at $60 per share late Wednesday, raising $1.68 billion in one of the most anticipated tech listings of the year.
The quantum computing company offered 28 million shares as part of the upsized offering, signaling strong investor appetite ahead of its public market debut on Thursday.
Underwriters have been granted a 30-day option to purchase an additional 4.2 million shares if demand exceeds initial expectations, giving the deal room to grow further.
The IPO represents a landmark moment for the quantum computing sector, which has been gaining significant attention from investors tracking the next wave of advanced technology development.
Quantum computing companies have faced intense scrutiny from Wall Street as the industry pushes toward commercially viable systems capable of solving complex problems beyond the reach of classical computers.
Quantinuum’s offering comes amid a broader resurgence in technology IPOs, with investors showing renewed willingness to back high-growth companies operating at the frontier of scientific and computational innovation.
The $60 pricing reflects confidence in the company’s trajectory, as underwriters and institutional investors evaluated the business ahead of the public listing scheduled for Thursday.
The option to sell an additional 4.2 million shares, commonly known as a greenshoe option, provides underwriters with a mechanism to stabilize the stock price following its market debut.
A successful trading debut would bolster sentiment across the quantum computing space, an area that has attracted growing interest from major technology and defense-adjacent investors in recent years.
The quantum computing industry broadly is considered a long-term strategic priority by governments and large technology firms alike, with considerable investment flowing into hardware and software development across the sector.
Quantinuum’s listing marks one of the largest technology IPOs so far in 2026, and market participants will be closely watching first-day trading volume and price performance as a barometer for investor sentiment toward emerging deep-tech companies.
