SEALSQ (NASDAQ: LAES) detailed its SEALQUANTUM strategy to build a Sovereign Quantum Vertical Stack, combining investments, technology integration and commercial agreements across the quantum value chain. The company has invested approximately $24.5 million in two pure-play quantum computing firms: Quobly (€15 million, about $17.5 million) and EeroQ ($7.0 million).

According to SEALSQ, it led Quobly’s €115 million Series A, gaining supervisory board representation, and has made a series of strategic investments in EeroQ under a “Quantum Made in USA” strategy. On July 10, 2026, SEALSQ and Quobly announced a $5 million commercial agreement for integrating SEALSQ post-quantum security, secure semiconductors, Cryo-CMOS ASIC technology, PKI and engineering services into Quobly’s next-generation silicon quantum platform.

SEALQUANTUM targets $200 million of SEALSQ capital, with more than $60 million already deployed across its broader quantum and post-quantum ecosystem, aiming to monetize links from Root of Trust and PQC through secure semiconductors, photonics, quantum communications and quantum computing.
