Analysts turned increasingly bullish on Quantinuum on Monday after the company’s post-initial public offering (IPO) quiet period expired.
Several brokerages initiated coverage, highlighting the quantum computing company’s long-term growth potential.
The quiet period had prevented IPO underwriters from publishing research reports, ratings, or valuation targets on the stock.
With that restriction lifted, Wall Street firms released their first formal views on the company.
Despite the wave of positive analyst initiations, Quantinuum QNT shares were down about 2.69% on Monday, trading near $73.54.
Analysts highlight Quantinuum’s technology leadership
Cantor Fitzgerald analyst Troy Jensen initiated coverage with an Overweight rating, arguing that Quantinuum could emerge as a commercial leader if its trapped-ion quantum computing technology proves to be the industry’s preferred approach.
Trapped-ion systems use ions suspended in a vacuum and manipulated by lasers, a method that generally offers higher fidelity, or operational accuracy.
Quantinuum’s latest Helios system replaces industry-standard ytterbium with Barium-137 isotopes for its quantum bits, or qubits.
The change enables the system to manipulate qubits using highly stable visible and infrared lasers rather than ultraviolet light, which is considered more prone to errors.
As Jensen noted Monday, “Quantinuum envisions a hybrid compute world” comprised of CPUs, GPUs, and quantum processors, “with quantum computing as the foundational layer.”
That vision has led the company to develop a full-stack platform combining hardware, software and applications.
Rosenblatt Securities analyst John McPeake also expressed confidence in the company’s technology, assigning a Buy rating and a $155 price target, significantly above the stock’s current trading level.
McPeake said Quantinuum “has set the industry benchmarks in quantum compute,” citing the company’s Helios platform, which achieved an industry-leading 99.92% two-qubit gate fidelity.
Strong backing, commercial pipeline draw attention
JP Morgan also initiated coverage with a positive outlook, pointing to Quantinuum’s financial position following its IPO and its origins within Honeywell.
The company was formed in 2021 through the merger of Honeywell International’s quantum division and Cambridge Quantum, a UK startup that spun out of the University of Cambridge in 2014.
JP Morgan analyst Harlan Sur highlighted the team’s more than a decade of experience developing trapped-ion quantum systems and noted that the company has introduced three generations of quantum computers over the past six years, with plans to scale to larger systems by the end of the decade.
Sur also said the company’s “commercial momentum is building,” supported by a customer pipeline spanning financial services, telecommunications and automotive markets.
Last month, Quantinuum also reached a tentative agreement with the Commerce Department, exchanging a minority equity stake for federal funding.
Growth opportunity tempered by execution risks
Not all analysts adopted an outright bullish stance.
Morgan Stanley initiated coverage with an Equal Weight rating and a $78 price target, acknowledging the company’s technological progress while cautioning that commercialization risks remain.
The firm wrote that Quantinuum’s “differentiated technology and consistent execution” make it one to watch, but said a neutral rating best reflects the balance between long-term opportunity and execution risk.
Morgan Stanley also said the company’s trapped-ion architecture and technical execution demonstrate a “credible path to fault tolerance,” referring to the ability of quantum computers to avoid or correct errors during computation.
Mizuho also initiated coverage with an Outperform rating and a $90 price target, forecasting significant expansion for the quantum computing industry.
The firm estimates the market will grow from an annual run rate of about $1.1 billion in 2025 to roughly $15 billion by 2030 and $205 billion by 2035.
