Quantum computing is an emerging field that requires businesses to prepare for a world where existing encryption technologies might not be effective anymore. Consequently, there have been a number of advances in the area of Post-Quantum Cryptography (PQC), which is a new generation of cryptography algorithms that cannot be compromised by the quantum computers. The governments, banks, cloud computing services, and technology companies invest vast amounts of resources into ensuring quantum-safe security measures.
The increased use of cloud computing, Internet of Things, mobile payments, and AI is another factor that promotes the growth of this field. In addition to that, various global efforts of cybersecurity organizations in terms of standardization and research and development help lay solid groundwork for implementing PQC on an industry-wide scale.
Post-Quantum Cryptography (PQC) Market reached a value of USD 1.35 billion in 2025, and it is predicted to grow up to USD 22.68 billion by 2033 at an exceptionally high CAGR of 42.33% in 2026-2033. Increase in fear of quantum-based cyberattacks, increased regulation support, and quick adoption of quantum-resistant encryption in the critical infrastructure will drive the growth of the market.
