Quantinuum Stock Opens Above IPO Price, Then Fades

Quantinuum (QNT) debuted on NASDAQ with a 13% pop above its $60 IPO price, opening at $68, but quickly faded to around $62 as sellers stepped in. The quantum computing company raised $1.68 billion from the IPO with 20x oversubscription. However, with 2025 revenue of only $30.9 million against a $192.6 million net loss, the stock's decline from intraday highs reflects investor concerns about the company's burn rate. The IPO sparked a sector rotation, with most quantum computing peers declining.

The Pure Plays: 5 Companies Building Quantum From the Ground Up

The article profiles five pure-play quantum computing companies pursuing different hardware approaches: IonQ (trapped-ion systems), D-Wave (annealing and gate-model systems), Rigetti (modular superconducting chiplets), Xanadu (photonic quantum computing), and Infleqtion (neutral-atom systems). Each company has demonstrated significant technical milestones in 2025-2026, including record gate fidelities, distributed quantum networking, and commercial deployments. The article emphasizes that while quantum computing is making measurable progress, no single modality has yet proven definitively superior, and the field remains in early commercialization stages with paying customers and peer-reviewed results.
