SEALSQ Corp reports a post-quantum project pipeline exceeding $100 million through 2029, signaling growing commercial investment in its future technology. The company also announced preliminary nine-month 2026 revenue of $16.3 million, a 65% increase year-on-year, alongside $463.0 million in cash reserves as of September 30, 2026. A key driver for future growth is the VaultIC408, which has achieved NIST FIPS 140-3 Level 3 validation, a high level of security certification for industrial and IoT applications.

SEALSQ Achieves 65% Revenue Growth with $16.3M in 9M 2026

This active pipeline, exceeding $200 million in total, demonstrates increasing commercial interest in future-proof security solutions despite inherent risks associated with conversion, customer validation and technical integration. The revenue growth stems from multiple sources, including continued demand for the Vault-IC secure-element family in industrial and IoT applications, as well as expansion of recurring revenue from PKI subscriptions and certificate-management services. IC’Alps SAS, acquired earlier in the year, contributed approximately $3.8 million to the 9M 2026 revenue through custom ASIC design and secure semiconductor engineering services.

The ramp-up of the Quantix Edge Security sovereign semiconductor design and personalization center in Murcia, Spain, is also contributing to the company’s expanding capabilities, SEALSQ says. Carlos Moreira, Founder, Chairman and CEO, said, “Our preliminary nine-month revenue of $16.3 million represents 65% growth year-over-year, with revenue increasing sequentially in each quarter of 2026.” This performance supports the reaffirmed full-year revenue outlook as the company continues to advance its post-quantum products toward commercialization.

The company’s financial position allows for continued investment in these areas, with approximately $463.0 million in cash, cash equivalents and restricted cash at the end of September 2026, providing significant liquidity in a rapidly evolving technology sector, according to SEALSQ. This financial strength is expected to support the commercialization of post-quantum semiconductors, which the company anticipates will contribute more significantly to revenue starting in 2027.

John O’Hara, CFO, added, “Based on our preliminary nine-month revenue, our reaffirmed full-year 2026 revenue guidance implies fourth-quarter revenue of $11 million to $20 million.” The company remains focused on converting its pipeline into production revenue and deploying capital carefully to support growth. Recent operational milestones are also driving the company forward.

The completion of the acquisition of Miraex SA in June expanded capabilities in quantum-photonics interconnect technology, with founder Daniel Brau appointed Chief Quantum Officer. A majority investment in Wecan Group is accelerating the development of a post-quantum AI compliance co-pilot for financial institutions, while a lead investment in a Series A round and a subsequent $5 million commercial agreement are integrating cryo CMOS IPs and post-quantum security into future platforms.

First shipments of the QVault TPM183 are expected in the fourth quarter, subject to customer qualification. The company is also actively pursuing certifications for its QVault TPM ecosystem, targeting TCG certification for the TPM183 in February 2027 and the TPM185 in May 2027.

The company unveiled VaultIC409, a quantum-ready secure element built on the QS7001 platform, with engineering samples planned for the second quarter of 2027. These advancements, combined with alignment with regulatory initiatives like the ANSSI post-quantum mandate in France and the White House Executive Order on quantum security, emphasise the company’s commitment to securing the future of digital infrastructure.

Our preliminary nine-month revenue of $16.3 million represents 65% growth year-over-year, with revenue increasing sequentially in each quarter of 2026.

Ivy Delaney has been working with neural networks and machine learning since the mid-nineties, back when a couple of hidden layers and a long afternoon of training counted as ambitious. She has watched the field go from academic curiosity to the thing quietly running underneath everything, and she brings that long view to quantum computing. For Quantum Zeitgeist she covers the ground where the two fields meet. That means quantum machine learning and the variational algorithms it leans on, and it also means the less glamorous but more interesting story of classical machine learning already doing real work inside quantum machines, decoding error-correcting codes, calibrating noisy hardware and learning the error models that simulators depend on. She writes about the hardware those algorithms have to run on too, and about the post-quantum cryptography scramble that the same hardware has set off. Her stories typically start with the paper, whether that is peer-reviewed work, conference proceedings or an arXiv preprint, with the source linked so you can hold a claim up against the research it came from. She is unimpressed by benchmarks that will not say what they beat, and by demonstrations that only work in the press release.
