SEALSQ Corp

SEALSQ Corp announced a strategic expansion into the full quantum technology stack through targeted investments and acquisitions in leading quantum computing companies. The company is assembling a "Root-to-Qubit" stack, connecting its post-quantum security silicon to next-generation quantum hardware. This strategy involves investments in EeroQ, Quobly, and Miraex, with a pipeline for further opportunities, aiming for diversified exposure to multiple qubit modalities while leveraging its existing revenue-generating secure semiconductor business.

SEALSQ Corp announced the completion of its acquisition of 100% of Miraex SA, a developer of photonics-based quantum interconnect solutions. This acquisition is crucial for completing the quantum interconnect layer of the company's Quantum Sovereign Vertical Stack, enabling secure quantum connectivity for its Quantum Orbital Space Cloud program. Additionally, SEALSQ will invest CHF 5 million in WeCan to accelerate the development and deployment of next-generation compliance solutions and post-quantum financial security infrastructure.

SEALSQ Corp announced its participation as a lead investor in Quobly's €130 million Series A financing round, alongside ST Microelectronics, Isalt, and BPI France. This investment, made via the SEALSQ Quantum Fund, supports Quobly's industrialization of silicon-based quantum processors and strengthens SEALSQ's Quantum Vertical Sovereign Stack strategy. Carlos Moreira, SEALSQ's CEO, will join Quobly's Board of Directors. The SEALSQ Quantum Fund has grown from an initial $20 million to $200 million and has deployed approximately $30 million in other strategic investments.

SEALSQ Corp has acquired a majority equity stake in Wecan Group, following an initial 28% investment made a year ago. As part of this strategic transaction, SEALSQ will invest CHF 5 million to accelerate Wecan Group's development and support the deployment of next-generation compliance Co-Pilote and post-quantum financial security solutions for the global financial industry. The investment, made through SEALSQ's Quantum Fund, aims to create an integrated quantum-resilient trust platform by combining Wecan Group's compliance expertise, SEALSQ's post-quantum technology, and WISeKey's digital identity infrastructure.

SEALSQ Corp announced the acquisition of 100% of Miraex SA, a Swiss photonics pioneer, to complete the quantum interconnect layer of its Quantum Sovereign Vertical Stack. This strategic move, funded by SEALSQ's $200 million Quantum Fund (with over $65 million already deployed), is crucial for uniting post-quantum silicon, orbital infrastructure, and distributed quantum sensing. Miraex's proprietary Thin Film Lithium Tantalate (TFLT) Photonic Integrated Circuit (PIC) platform enables the conversion of quantum information between microwave and optical frequencies, accelerating SEALSQ's Quantum Orbital Space Cloud (QOSC) program and its vision for a global quantum internet.

SEALSQ Corp announced its QS7001 Post-Quantum Secure Element received NIST Entropy Source Validation (ESV) Certificate #E333 under SP 800-90B. This validation, confirmed on May 27, 2026, is a crucial prerequisite for achieving FIPS 140-3 and Common Criteria EAL5+ certifications, which are essential for regulated markets in the US and EU. The QS7001, SEALSQ's flagship Post-Quantum Secure Element, uses a ring oscillator-based physical noise source and is classified as "Open for Reuse," enabling broader adoption. This milestone underscores SEALSQ's commitment to high security standards for IoT, industrial, government, and defense applications.

SEALSQ Corp announced a further strategic investment in EeroQ, a U.S.-based quantum chip design company, and committed to serving as the lead investor in EeroQ's upcoming financing round. This builds on previous investments in December 2025 and February 2026, reinforcing SEALSQ's "Quantum Made in USA" and Quantum Highway ™ strategies. The investment, made through SEALSQ's Quantum Fund (SEALQUANTUM.com), aims to accelerate the development of a fully integrated Quantum Vertical Sovereign Stack. This expanded commitment will help EeroQ scale its helium-based quantum processor, expand its Chicago R&D, and accelerate CMOS-compatible fabrication milestones.

SEALSQ Corp's joint venture, QUANTIX EDGE SECURITY, has chosen Murcia, Spain, as the site for its new 40 million semiconductor design industrial center. The project, which involves SEALSQ, WISeKey, SETT.ES, OdinS, and TProtege, will focus on advanced semiconductor solutions for strategic sectors like defense, automotive, and IoT, incorporating cybersecurity, post-quantum technology, AI, and RISC-V systems. This initiative aims to strengthen European technological autonomy and create highly qualified jobs in the region.

SEALSQ Corp announced the successful integration of IC’Alps into its semiconductor and post-quantum technology ecosystem. This milestone significantly strengthens SEALSQ’s chip design and ASIC development capabilities, aligning with Europe’s strategic objective of technological sovereignty and semiconductor independence. The integration accelerates the development of secure semiconductor technologies for AI, IoT, satellite communications, defense, and post-quantum cybersecurity applications. SEALSQ is now positioned as a leading European provider of trusted semiconductor solutions, supporting critical infrastructure and secure digital ecosystems.

SEALSQ Corp and its parent WISeKey International Holding Ltd announced the launch of the WISeRobot.ch platform, unveiling a product roadmap for a next-generation human-centric AI robotics system. This system is secured with post-quantum cryptographic technology, integrating SEALSQ's quantum-resistant semiconductors and PKI infrastructure with WISeKey's digital identity expertise. The WISeRobot previously debuted at the World Economic Forum in Davos in January 2026, where a Proof of Concept demonstrated secure digital identity and protected communications in a live robotics environment. The platform aims to establish a robust security foundation for AI-driven and autonomous systems deployed in critical sectors.
