WISeKey International Holding Ltd announced that its subsidiary WISeID is positioned to benefit from the accelerating global transition to post-quantum digital identity and authentication standards. This opportunity arises from emerging government initiatives aimed at migrating to post-quantum cryptography (PQC), including a recently reported draft U.S. Executive Order. The proposed policy framework would require federal agencies to transition key establishment mechanisms to post-quantum standards by 2030 and digital signatures by 2031.

These measures reflect a broader global recognition that future quantum computers may compromise today’s widely deployed public-key cryptographic systems. This creates significant risks for digital identity, authentication, secure communications, and data protection. Digital signatures serve as the foundation of trust across the digital economy, enabling the authentication of users, devices, applications, and transactions. Key establishment technologies secure communications by allowing trusted parties to exchange cryptographic keys used to encrypt and decrypt sensitive information.

"Governments and enterprises worldwide are moving from planning to implementation on post-quantum security, creating a clear, time-bound upgrade cycle for digital identity and authentication," said Carlos Moreira, Founder and CEO of WISeKey. He added that WISeID is designed to address this transition by providing quantum-resilient identity, credential management, and authentication capabilities that can be integrated into existing infrastructures.

WISeID’s digital identity ecosystem provides trusted authentication and identity management solutions for individuals, enterprises, governments, and connected devices. The platform is expected to benefit from increasing demand for quantum-resistant digital identity solutions, secure authentication services, post-quantum certificate management infrastructures, and quantum-safe access control.

The growing urgency surrounding "harvest now, decrypt later" threats has further accelerated demand for quantum-resistant security solutions. Organizations are seeking pathways to migrate their digital trust infrastructures before quantum threats become operational realities. WISeID integrates with post-quantum technologies developed by SEALSQ Corp., a subsidiary of WISeKey focusing on semiconductors, PKI, and post-quantum technologies.

As governments, critical infrastructure operators, financial institutions, healthcare organizations, and technology providers accelerate their quantum-readiness initiatives, WISeID believes the digital identity sector is entering a new phase of growth driven by the need for long-term cryptographic resilience.

WISeKey International Holding Ltd and its subsidiary SEALSQ Corp announced that their jointly established special purpose vehicle, Quantisimo Corp, has entered into a non-binding Letter of Intent with GigCapital8 Corp. The proposed transaction aims to establish a Nasdaq-listed strategic quantum technology platform with a pre-money enterprise value of approximately $575 million. The parties intend to increase this valuation to $2 billion through the build-up consolidation of up to five additional quantum companies.

The business combination between Quantisimo and GigCapital8 is currently expected to close during the first quarter of 2027. Quantisimo was created to build a Trusted Quantum Pure-Play platform, leveraging proprietary technologies, strategic investments, and assets from the SealQuantum.com portfolio. The platform is designed to provide investors with direct exposure to the quantum economy, focusing on the development and deployment of trusted quantum technologies.

Strategic Vision and Market Context

The strategic vision for Quantisimo is supported by the Executive Order ‘Ushering in the Next Frontier of Quantum Innovation’ signed on June 22, 2026. This policy is expected to accelerate quantum computing, sensing, and networking, thereby expanding market opportunities and public-private partnerships. Quantisimo aims to capitalize on this momentum by offering quantum-enabled applications and post-quantum security solutions.

Transaction Details and Future Plans

The following table outlines the key financial and strategic targets of the proposed transaction:

SEALSQ is expected to contribute selected assets and strategic interests from its SealQuantum.com portfolio to Quantisimo, subject to the completion of the business combination and board approvals. These contributions include investments, technologies, and intellectual property intended to strengthen Quantisimo's position in the quantum ecosystem.

Management Commentary

Carlos Creus Moreira, Founder and CEO of WISeKey and Chairman of SEALSQ, emphasized the transformative potential of the quantum age. He stated that the partnership with GigCapital Global is designed to accelerate scale and enhance market access. Dr. Avi Katz, Founder and CEO of GigCapital Global, highlighted that Quantisimo represents a unique opportunity to create a public company focused on the emerging quantum economy for military and commercial markets.

The proposed transaction remains subject to the execution of definitive agreements, regulatory approvals, shareholder approvals, and other customary closing conditions. There can be no assurance that the transaction will be completed.
