Listing Overview

Quantinuum Inc. (ticker: QNT) will begin trading on the NASDAQ exchange on June 4, 2026. The company plans to offer 21,052,632 shares of common stock in the IPO, with an estimated total offering size of $1.00 billion and an implied total market capitalization of $1.21 billion at the midpoint of the proposed price range. This will mark one of the largest U.S.-listed quantum tech IPOs of 2026 to date, with the company upsizing the offering on June 1, 2026, per preliminary public filings.

Capital Raising and Dilution Context

Per the latest amended S-1/A filing on the SEC’s EDGAR platform, the total offering size equals approximately 82.6% of the implied post-IPO market capitalization at the midpoint price range. The offered shares will represent the entirety of the public float following the listing, resulting in material equity dilution for existing pre-IPO shareholders.
