Post-Quantum Cryptography Market worth $3.80 billion by 2031
The report "Post-Quantum Cryptography Market by Solution (Cryptographic Discovery, Risk & Migration Management Software, Quantum-Safe Key Management & Cryptographic Infrastructure, PKI, Digital Signatures & Identity Security Solutions) - Global Forecast to 2031", The post-quantum cryptography (PQC) market is projected to grow from USD 0.60 billion in 2026 to USD 3.80 billion by 2031, registering a CAGR of 44.5% during the forecast period. A key driver is the growing need for cryptographic agility, which enables organizations to replace or update cryptographic algorithms as security requirements evolve. Cryptographic functions are embedded across applications, digital certificates, network protocols, hardware, and enterprise infrastructure, making future upgrades complex and resource-intensive. Organizations are increasingly prioritizing flexible cryptographic architectures that support algorithm transitions without requiring extensive redesign of existing systems. This is encouraging demand for adaptable cryptographic software, centralized key management, discovery tools, and quantum-safe infrastructure that can accommodate evolving security requirements.

Based on solution, the quantum-safe hardware segment is expected to hold the largest market.
Quantum-safe hardware supports integrating cryptographic capabilities into devices, infrastructure, and security appliances. Hardware security modules, secure elements, and embedded security components can protect cryptographic keys and support secure operations in environments with stringent security requirements. As organizations modernize their infrastructure, hardware vendors are incorporating capabilities designed to support quantum-resistant algorithms alongside existing cryptographic mechanisms. These developments matter for data centers, enterprise security infrastructure, telecommunications equipment, and connected devices. Hardware-based implementations must also address processing requirements, memory constraints, and compatibility with established systems. Demand for quantum-safe hardware is expected to remain significant as organizations upgrade security components and incorporate quantum-resistant capabilities into new infrastructure deployments.
By vertical, the IT & ITeS segment is projected to register the fastest growth during the forecast period.
IT service providers, cloud platforms, software vendors, and technology infrastructure operators manage cryptographic functions across applications, digital identities, data exchanges, and communication protocols. Transitioning these environments requires updates to cryptographic libraries, authentication mechanisms, certificates, and secure communication systems. The scale and interconnectedness of technology platforms drive demand for automated cryptographic discovery, compatibility testing, and centralized migration management. Technology providers must also evaluate how quantum-resistant algorithms can be integrated without disrupting customer services or application performance. IT service providers are positioned to support PQC consulting, implementation, and migration projects across multiple industries. These requirements are expected to accelerate adoption across the IT & ITeS segment throughout the forecast period.
By region, North America is estimated to account for the largest market share.
North America's leading position is supported by strong cybersecurity investment, an established technology ecosystem, and the presence of major cloud providers, semiconductor companies, and cryptographic security vendors. Organizations across financial services, government, defense, and technology are assessing quantum-related risks and preparing to modernize existing cryptographic infrastructure. The US government has also advanced PQC adoption through NIST's finalized standards and federal migration guidance, encouraging agencies and suppliers to identify vulnerable cryptographic systems and plan transitions. Demand is expected across quantum-safe hardware, cryptographic software, secure communications, key management, and migration services as organizations incorporate quantum-resistant capabilities into their security architectures.
