SEALSQ, WISeKey and WISeSat.Space launch a post-quantum-secure satellite aboard a SpaceX mission
On 2025-12-01 SEALSQ (Nasdaq: LAES), parent WISeKey and affiliate WISeSat.Space announced the successful launch of a new WISeSat satellite carrying SEALSQ post-quantum-secure semiconductors aboard a SpaceX mission, advancing the group's quantum-resistant IoT-and-space security constellation. The launch is a completed deployment milestone for the post-quantum satellite strategy.
A completed launch placing SEALSQ post-quantum-secure chips in orbit is a concrete deployment milestone for the chip-to-space security thesis; it is a single satellite within a broader WISeKey/WISeSat program, so its standalone materiality is modest.
Quantum-resistant root-of-trust in low-cost satellites positions SEALSQ in the secure-space-IoT niche; revenue depends on constellation scale and customer demand for orbital PQC.
