Post-Quantum Cryptography Market Projected to Reach $3.8B by 2031
A new MarketsandMarkets report forecasts the post-quantum cryptography sector will expand at a 44.5% annual growth rate over the next five years.
The global post-quantum cryptography market is on track to grow more than sixfold in five years, rising from an estimated $0.60 billion in 2026 to $3.80 billion by 2031, according to a new report from research firm MarketsandMarkets. The projected compound annual growth rate of 44.5% underscores intensifying demand for encryption systems designed to withstand attacks from next-generation quantum computers.
Post-quantum cryptography refers to cryptographic algorithms engineered to remain secure even as quantum computing hardware advances toward capabilities that could render current encryption standards obsolete. Governments, financial institutions, and technology firms have accelerated investment in the field as quantum hardware development moves out of research laboratories and closer to commercial deployment.

The MarketsandMarkets analysis draws on more than 400 market data tables, reflecting broad cross-industry interest in upgrading security infrastructure before quantum threats materialize at scale. Regulatory pressure, particularly from national cybersecurity agencies that have begun mandating quantum-resistant standards, is widely regarded as a key demand driver alongside enterprise risk management priorities.
The market's rapid expansion trajectory places post-quantum cryptography among the fastest-growing segments within the broader cybersecurity industry, as organizations race to future-proof sensitive data against an emerging class of computational threats that classical encryption was never designed to address.
