Quantinuum, IQM Quantum Computers, and Pasqal are among the quantum employers that entered public markets in 2026. Quantinuum priced its initial public offering (IPO) at US$60 a share on June 3, raising US$1.68 billion in gross proceeds, and its shares began trading the next day. IQM Quantum Computers completed its merger with a special purpose acquisition company (SPAC) on July 1 and began trading on Nasdaq on July 2. Pasqal completed its own SPAC merger on August 27 and began trading on August 28. On November 12, 2026, the three companies had 178 open roles on Quantum Careers. Infleqtion and D-Wave Quantum, also public companies, had 54 and 44.
A stock market listing changes the form of employee equity and the dates on which employees can sell it. It also creates teams that a private hardware company rarely needs. The sections below are general information for candidates weighing an offer, not financial, legal, or tax advice. The terms of any specific grant are set by the employer’s equity plan and the grant agreement.
Who has gone public

IonQ, Rigetti Computing, and D-Wave Quantum were public before 2026. More listings may follow. In July 2026, The Quantum Insider, citing Israeli press reports, said Quantum Art and Classiq were in advanced talks about SPAC mergers. Neither company commented.
How equity changes
At a private company, employees usually receive stock options. An option is the right to buy shares at a fixed exercise price. It has value to the employee only if the shares are worth more than that price. Until the company is sold or listed, private shares are hard to sell, apart from occasional tender offers or secondary sales. Their value is an estimate.
At a public company, employees more often receive restricted stock units (RSUs). Each unit entitles the employee to one share with no purchase price. The share is usually delivered when the unit vests, although some plans settle later. The shares trade every day, so their value is known on any given day. For a candidate comparing offers, equity at a public company is part of current compensation, and it moves with the share price.
The type and size of the grant
Ask whether the grant is options or RSUs. Ask whether it is set as a number of shares or as a dollar value. A dollar-value grant is converted into shares at a stated price, often an average over several trading days. A lower conversion price produces more shares.
The vesting schedule
Ask for the vesting schedule and for any cliff before the first shares vest. Ask whether the company makes annual refresh grants to existing staff. Once the first grant has fully vested, new equity usually comes from refresh grants, promotion grants, or an employee stock purchase plan where the company offers one.
When shares can be sold
Two sets of rules limit sales. A lockup agreement stops insiders, usually including existing employees, from selling for a period after the listing. The US Securities and Exchange Commission’s investor site notes that lockup terms vary and most last 180 days after an IPO. A SPAC merger sets its own lockup terms in the merger agreement. Separately, public companies generally have an insider trading policy. It usually limits employee trades to windows that open after each earnings release. Anyone who holds material nonpublic information about the company is barred from trading, whatever the window.
Employees who joined before the listing often hold options with a low exercise price. Those options may now be worth far more than at grant. What an employee actually receives still depends on the share price when the lockup ends and the employee chooses to sell.
The new roles a public company needs
A US domestic listed company reports to shareholders and regulators every quarter. Foreign private issuers such as IQM follow a different reporting schedule, but they too publish audited annual accounts and disclose material events. Auditors test whether the company’s financial controls work. Listings on Quantum Careers in November 2026 include roles of this kind. They show what these companies are recruiting for; they do not show that the stock market listing caused each hire.
| Employer | Roles listed |
|---|---|
| Quantinuum | Senior Paralegal (Securities); Director, FP&A; Vice President, Corporate Development; Director, M&A and Strategic Partnerships |
| IonQ | Staff Automation Engineer, Internal Audit; Lead, Accounting Consolidations; Staff FP&A Business Partner |
| PsiQuantum (privately held) | Director, Investor Relations |
Public companies can also use their shares to pay for acquisitions. IonQ’s 2025 acquisition of Oxford Ionics, valued at US$1.075 billion at announcement, was paid almost entirely in IonQ stock, which made up US$1.065 billion of the total. An acquisition brings integration work across teams, systems, and countries. Employees of both companies gain new colleagues, and some roles overlap.
What candidates can learn from public filings
Public companies must disclose their finances. The annual report shows revenue, losses, cash, and how fast the company is spending cash. The risk factors section lists what management sees as the main threats to the business. A US domestic company also files quarterly reports and a proxy statement that shows executive compensation. Foreign issuers such as IQM file an annual report on Form 20-F and current reports on Form 6-K, all searchable on the SEC’s EDGAR database.
Candidates should read the latest annual report before an interview. The report answers questions about runway and priorities that a recruiter may not, and it shows which parts of the business are getting investment.
For employers
Candidates can now value an equity offer from a public quantum company at that day’s share price. Listings that state the type of grant and the vesting terms answer the first question a candidate will ask. Our guide to quantum compensation covers how candidates negotiate equity.
