SEALSQ Corp (NASDAQ: LAES) announced plans to launch its first satellite for the Quantum Spatial Orbital Cloud (QSOC) aboard a SpaceX mission in the fourth quarter of 2026. The satellite will serve as part of an orbital platform designed to provide post-quantum security services from space.

The company stated that QSOC will combine post-quantum cryptography, quantum random number generation, secure digital identity infrastructure, trusted edge AI processing, and satellite-based secure communications. The initiative aims to create computing nodes in orbit capable of delivering quantum-resistant cybersecurity services.

SEALSQ plans to expand the constellation to up to 100 satellites by 2033, with full operational capability targeted for that year. The company said the project builds upon experience from 21 partner-operated satellites launched by SpaceX since 2023, through which it tested space-security technologies including secure semiconductors and cryptographic identity management systems.

The project represents a collaboration between SEALSQ and WISeKey, with SEALSQ contributing post-quantum semiconductors, secure microcontrollers, and cryptographic technologies, while WISeKey's subsidiaries provide orbital infrastructure, satellite manufacturing capabilities, and launch operations.

"The future of cybersecurity will be defined by the convergence of artificial intelligence, post-quantum cryptography and space infrastructure," said Carlos Moreira, founder and CEO of SEALSQ and WISeKey. "The Quantum Spatial Orbital Cloud is our vision for creating a trusted digital layer above the Earth capable of securing communications, identities, devices and AI systems against the threats of tomorrow."

Under the commercial framework, SEALSQ will operate the cloud services layer, managing customer relationships, security services, digital identity infrastructure, and AI-powered applications. The constellation is expected to provide global coverage with enterprise-grade service availability once fully operational.
