Quantinuum prices upsized Nasdaq IPO at $60 per share, raising about $1.68B; trading begins 2026-06-04 as QNT
Quantinuum priced its upsized initial public offering of 28,000,000 shares of Class A common stock at $60.00 per share, raising gross proceeds of approximately $1.68B. According to the company's pricing release, the price came in above the $53.00-$55.00 range set in the 2026-06-01 amendment and the share count rose from 26,500,000; underwriters hold a 30-day option for up to 4,200,000 additional Class A shares to cover over-allotments. The shares are expected to begin trading on the Nasdaq Global Market on 2026-06-04 under the ticker QNT, with the offering expected to close 2026-06-05. The registration statement was declared effective by the SEC on 2026-06-03. J.P. Morgan and Morgan Stanley acted as joint lead active book-running managers, with Jefferies and Evercore ISI as additional active book-running managers. Per Bloomberg and Reuters/CNBC reporting, the print implies a valuation of roughly $15.6B on outstanding shares, and Honeywell retains about 48.1% of combined voting power after the offering.
This is the completed, above-range pricing of the year's largest pure-play quantum IPO at about $1.68B in gross proceeds, well clear of the $500M-pure-play financing magnitude that anchors the high end of the rubric, but scored 8 rather than 9 because the listing was heavily pre-signaled across the 2026-05-26 and 2026-06-01 filings; the completed raise is investor-material both as a roughly $1.68B balance-sheet event for Quantinuum and as the first public-market valuation reference for the trapped-ion modality.
A $60 print above the $53-55 range establishes a roughly $15.6B public reference valuation against which IonQ, Rigetti, and D-Wave will be marked, and crystallizes Honeywell's deconsolidation economics while leaving Honeywell with about 48.1% of voting power; a successful first-day trade would, if sustained, reopen the public-market financing channel for other pure-play quantum names that had been reliant on private rounds and PIPE structures.
