NASDAQ:QNT 9 May 2026 - 7 July 2026

Quantinuum Inc. shares jumped in afternoon trading on Tuesday as investors bought into quantum-computing names after Washington set a 2028 target for a powerful research-grade quantum computer and the newly public company added a fresh enterprise-computing tie-up.

Quantinuum’s first stretch as a public company remained volatile Friday, with QNT last trading at $55.26, down $1.38, after the Honeywell-backed quantum computing company priced its initial public offering, or IPO, at $60 a share earlier this month. The move matters for the stock because a break below the offer price often signals that investors are reassessing the valuation set by underwriters and early IPO demand.
