SEALSQ Corp raises Quantum Investment Fund to over $100 million

SEALSQ Corp increased its Quantum Investment Fund from $35 million to more than $100 million to support Europe’s quantum security, post-quantum technologies, and sovereign quantum computing efforts.

The company cited a liquidity position of almost $450 million and framed the fund increase as a step toward accelerating a fully Quantum-Safe digital ecosystem, contributing to a sovereign Quantum Computer, and creating a pan-European Quantum Corridor linking research, industry, and secure infrastructure.

SEALSQ described the fund’s focus as the convergence of quantum-resilient hardware, Post-Quantum Cryptography (PQC) algorithms, secure satellite and terrestrial communications, blockchain-backed identity systems, and AI-enhanced hardware security modules, along with semiconductors, Public Key Infrastructure (PKI), and provisioning services explicitly mentioned in its release.

The release listed recent investments and transactions executed across multiple countries: roughly $12 million committed in Spain with WISeKey and support from €20 million under the SETT.ES program to establish a Post-Quantum Semiconductor Personalization and Test Center in Murcia; $3.5 million invested in Switzerland’s WeCan Group and $10 million placed into WISeSat.Space for a satellite constellation; the acquisition of IC’Alps in France for about $14 million and an investment in ColibriTD to add Quantum Key Distribution (QKD) and hybrid PQC capabilities; and a strategic investment in U.S. firm EeroQ, which is developing a quantum approach using electrons on helium and was described as aligning with a Quantum Made in USA strategy.

“This integrated strategy is not a collection of isolated technologies, it is a coordinated mission to build the world’s first fully vertically integrated quantum computing ecosystem, support the development of a sovereign European Quantum Computer, and establish a Quantum Corridor that ancors Europe’s technological future,” said Carlos Moreira, CEO of SEALSQ. “By increasing our Quantum Fund to over $100 million, we are accelerating the innovation required to protect governments, enterprises, and citizens in the Quantum era. We are building the critical infrastructure of tomorrow, today.”

The communication included forward-looking statements and noted that actual results may differ materially because of risks and uncertainties described in SEALSQ’s filings with the Scope 1–3 Emission Calculator (SEC).
