SEALSQ Corp's stock saw increased attention following its lead role in Quobly's €130 million Series A financing round. SEALSQ invested from its Quantum Fund, which has grown to $200 million, alongside co-investors STMicroelectronics, Isalt, and BPI France. This deal deepens a partnership that began in November 2025, aiming to industrialize silicon quantum processors and launch commercial systems. SEALSQ CEO Carlos Moreira will join Quobly's board, signaling closer alignment and direct involvement in the company's commercial and technical roadmap. The collaboration focuses on combining Quobly's scalable FD-SOI quantum processors with SEALSQ's post-quantum chips and hardware security tools to build secure quantum computers. This strategy targets sectors requiring high security, such as defense, finance, and critical infrastructure. SEALSQ's Quantum Fund has previously backed several other companies in the quantum technology space, supporting its broader 'Quantum Vertical Sovereign Stack' strategy.
