SEALSQ Stock Jumps 13% Today: Company’s First Chip With Built-In Post-Quantum Encryption Draws Attention

• SEALSQ unveiled a new chip embedding NIST-standard post-quantum encryption.
• The chip, Quantum Shield QS7001, is scheduled to hit the market in mid-November 2025.
• Defense agencies, healthcare providers, energy operators, and IoT manufacturers are expected to be early adopters of the QS7001.

SEALSQ Corp. (LAES) on Monday unveiled the Quantum Shield QS7001, positioning it as the first hardware platform to integrate U.S. government–standardized post-quantum cryptography (PQC) directly into the hardware.

Quantum Shield QS7001 Provides 10x Performance Gains

The chip is scheduled to hit the market in mid-November 2025.The Quantum Shield QS7001 integrates NIST-standardized algorithms ML-KEM (CRYSTALS-Kyber) and ML-DSA (CRYSTALS-Dilithium) directly into the chip. 

According to SEALSQ, this architecture delivers up to tenfold performance gains, greater resistance against side-channel attacks, and sophisticated tamper protection. It also supports hybrid cryptography migration and allows customization through open firmware.

After the announcement, SEALSQ stock traded over 13% higher in Monday’s premarket. On Stocktwits, retail sentiment around the stock stayed in ‘extremely bullish’ territory amid ‘extremely high’ message volume levels. 

Why Quantum-Resistant Security Solution Is Important

QVault TPM variants are projected to roll out in the first half of 2026.The urgency behind quantum-proof systems stems from growing concerns that quantum computing will soon render traditional encryption methods such as RSA and ECC vulnerable. 

In 2024, the National Institute of Standards and Technology finalized its PQC standards, selecting algorithms like Kyber and Dilithium to counter these threats. Both U.S. and EU regulatory timelines now mandate PQC adoption by 2030 and 2026 to 2030, respectively, for critical sectors including defense, finance, healthcare, and energy.

The company is among a small group globally to hold Common Criteria EAL5+ and FIPS 140-3 certifications. Its secure manufacturing and personalization network spans Switzerland and France, with expansion plans in Spain, India, and the U.S. Defense agencies, healthcare providers, energy operators, and IoT manufacturers are expected to be early adopters of the QS7001.

SEALSQ stock has gained over 1,385% in the last 12 months.
