SEALSQ Corp

SEALSQ Corp has started the commercial phase of quantum photonics technology from Miraex SA, following its full acquisition of the Swiss company in June 2026. The acquisition, completed on June 2, 2026, was financed through SEALSQ’s $200 million Quantum Fund, which has already deployed more than $65 million into strategic quantum technology investments. Miraex’s proprietary Thin Film Lithium Tantalate Photonic Integrated Circuit platform converts quantum information between microwave and optical frequencies, addressing a key scaling challenge in quantum computing and networking. The commercial rollout targets distributed quantum computing, quantum networking, quantum sensing, and the Quantum Orbital Space Cloud. SEALSQ says the integration strengthens its Quantum Sovereign Vertical Stack, combining secure semiconductors, post-quantum cryptography, and quantum communications into a single sovereign platform.

WISeKey International reported preliminary unaudited first-half 2026 revenue of about $11.4 million, a 115% increase year-over-year, and reaffirmed its full-year 2026 revenue growth guidance of 50% to 100%. The company held approximately $495 million in cash and short-term investments with no debt as of June 30. Subsidiary SEALSQ has a commercial pipeline exceeding $225 million through 2029, supported by expected demand for post-quantum cybersecurity products. During the first half, WISeKey filed for WISeSat's planned Nasdaq listing to create a publicly traded quantum computing company valued at about $575 million. Full first-half 2026 financial results are expected in September 2026.

SEALSQ Corp. has entered into a $5 million commercial agreement with Quobly, a silicon quantum computing firm based in Grenoble, France. Under the deal, Quobly will integrate SEALSQ’s quantum-security technologies, secure semiconductor solutions, and engineering services. The collaboration covers the deployment of SEALSQ’s quantum-resistant technologies, including Cryo CMOS ASIC for quantum computing architecture and quantum-resistant PKI and trusted provisioning technologies. SEALSQ stated the agreement supports the broader objective of strengthening Europe’s technological sovereignty in quantum computing and post-quantum cybersecurity.

SEALSQ Corp announced that France's national cybersecurity agency ANSSI will stop certifying security products lacking quantum-resistant encryption starting in 2027 and require critical infrastructure operators and government agencies to buy only post-quantum-secure solutions by 2030. The company said this validates its strategic roadmap and noted that its QS7001 post-quantum secure element has received NIST SP 800-90B validation for its entropy source. Designed around NIST-standardized algorithms including ML-KEM and ML-DSA, the QS7001 is positioned as a hardware root of trust for semiconductors, IoT devices, critical infrastructure endpoints, satellite payloads, and industrial control systems. SEALSQ reported a pipeline of more than 150 customers and potential customers interested in its post-quantum cryptography products, with over 30 already working on integrating the technology into their devices.

WISeKey International Holding announced that its subsidiary WISeID is positioned to benefit from accelerating government initiatives to adopt post-quantum cryptography, including a reported draft U.S. Executive Order setting timelines for quantum-resistant digital signatures and key establishment. The proposed U.S. framework would require federal agencies to transition key establishment mechanisms to post-quantum standards by 2030 and digital signatures by 2031, reflecting global concern that future quantum computers could compromise current public-key systems. WISeID provides quantum-resilient identity, credential management, and authentication capabilities, and through integration with SEALSQ Corp.’s post-quantum technologies, it is developing next-generation cybersecurity architectures. The company expects increasing demand for quantum-resistant digital identity solutions, secure authentication, and post-quantum certificate management as organizations address harvest now, decrypt later threats.

WISeKey International and its subsidiary SEALSQ announced that their jointly established special purpose vehicle, Quantisimo Corp, has entered into a non-binding letter of intent with GigCapital8 to explore a business combination that would create a Nasdaq-listed strategic quantum technology platform. The combined company is expected to have a pre-money enterprise value of approximately $575 million, with plans to increase that valuation to $2 billion through the acquisition of up to five additional quantum companies. The transaction is currently expected to close during the first quarter of 2027. Quantisimo was created to establish a Trusted Quantum Pure-Play platform providing investors with direct exposure to the quantum economy.

SEALSQ Corp announced that its QS7001 Post-Quantum Secure Element is aligned with France's ANSSI mandate requiring quantum-resistant encryption for security product certification starting in 2027 and for all critical infrastructure and government agencies by 2030. The QS7001 is already validated under NIST SP 800-90B with ESV Certificate #E333 and implements NIST-standardized post-quantum algorithms including ML-KEM and ML-DSA. SEALSQ reports a pipeline of more than 150 customers and prospects for its post-quantum cryptography products, with over 30 actively integrating its technology. The ANSSI decision, confirmed on June 16, 2026, accelerates the transition to post-quantum security, and SEALSQ positions the QS7001 as a hardware root of trust with tamper-resistant design and hybrid cryptography support. The company also highlighted its broader Quantum Spatial Orbital Cloud program, with a QSAT payload launch planned aboard a SpaceX Falcon 9 in the fourth quarter of 2026.

WISeKey's subsidiary WISe.ART has become the world's first hardware-authenticated art platform while its other subsidiary SEALSQ Corp. has been granted a landmark divisional patent by the European Patent Office for its Back-to-Physical NFT technology. The patent covers the method of provisioning NFTs directly into tamper-proof semiconductors, creating an immutable, hardware-rooted link between a digital asset and a physical object. This enables WISe.ART to offer silicon-sealed provenance, ownership history, and authenticity certification that is independently verifiable and secured with post-quantum cryptography. The patent portfolio now spans a Swiss priority filing, the granted European divisional patent, a pending US application, and a further EPO divisional under examination. WISe.ART operates within WISeKey's global trust infrastructure, which secures over 2.6 billion devices, and targets the approximately $65 billion annual global art market.
