Post-quantum cryptography migration market to top $5.16 billion by 2030

By AI, Created 10:01 AM UTC, May 20, 2026, /AGP/ – The Business Research Company says the global post-quantum cryptography migration market is accelerating as quantum computing threats push organizations to replace vulnerable encryption systems. The market is projected to rise from $2 billion in 2025 to $2.41 billion in 2026, then reach $5.16 billion by 2030.

Why it matters: - Quantum computing is moving from a theoretical risk to a cybersecurity planning issue. - Organizations are being pushed to migrate to quantum-resistant cryptography to protect data confidentiality, integrity and authentication. - The shift could affect digital infrastructure, cloud security, financial services and regulatory compliance.

What happened: - The Business Research Company released its Global Market Report 2026 for post-quantum cryptography migration. - The report values the market at $2 billion in 2025 and projects $2.41 billion in 2026. - The report forecasts the market will reach $5.16 billion by 2030. - The report was published in London on May 20, 2026. - A free sample of the report is available. - The full market report is also available.

The details: - The market is expected to post a 20.7% CAGR from 2025 to 2026. - The forecast period points to a 21.0% CAGR through 2030. - The report cites escalating cybersecurity threats, continued dependence on classical cryptography, rising digital transactions, tighter data-security regulation and cloud-based security adoption as near-term growth drivers. - The report says advances in quantum computing, growing urgency around PQC adoption, hybrid cryptography demand, digital finance and fintech growth, and government data-protection efforts support longer-term expansion. - The report identifies quantum-resistant algorithms, hybrid cryptography migration, secure key management, regulatory compliance and planned cryptographic transitions as key trends. - Post-quantum cryptography migration means shifting current cryptographic systems and protocols to algorithms designed to resist attacks from quantum computers. - The report says this transition is necessary to preserve data security in a future where quantum machines could break traditional cryptographic methods.

Between the lines: - The market report frames PQC migration as a defensive race against quantum capability, not a speculative upgrade. - The scale of expected growth suggests enterprises and governments are moving from awareness to implementation planning. - A February 2026 Quantum Gate Limited survey found 65% of business, IT and cybersecurity leaders expect quantum computing to substantially raise cyber risks. - That finding helps explain why demand is rising now, even before quantum computers can broadly threaten today’s encryption.

What’s next: - The report expects hybrid cryptography and secure transition planning to remain central as organizations modernize encryption stacks. - The Asia-Pacific region is forecast to grow fastest over the coming years. - North America held the largest market share in 2025. - The report also covers South East Asia, Western Europe, Eastern Europe, South America, the Middle East and Africa. - More information is available through the company’s LinkedIn page and social channels, Facebook and X.

The bottom line: - PQC migration is emerging as a major cybersecurity market because the quantum threat is forcing buyers to plan now for encryption that can survive later.
