Quantinuum Lists on Nasdaq at $60, 20x Oversubscribed

Quantinuum (Nasdaq: QNT) started trading on Thursday after pricing its IPO at $60 a share, raising about $1.68 billion in the largest quantum listing on record. CEO Dr Rajeeb Hazra rang the Nasdaq closing bell, capping a deal we first flagged when the company filed its S-1. After years of speculation about which quantum name would test public markets at scale first, the answer arrived with a price tag in the mid-teens of billions and an order book that embarrassed most recent tech floats. Bloomberg put the order book at more than 20 times oversubscribed, with the order book weighted toward long-only institutions. The deal was priced $5 above its raised range after being upsized twice. Shares opened at $68, about 13% above the $60 issue price. They reached a high of $71.35 and a low of $60.12 before settling near $61 by the afternoon. Ticker: QNT, Nasdaq Global Market.
