Global Post-Quantum Cryptography Market Size Projected to Reach $2.84 Billion By 2030

VANCOUVER, BC, Aug. 19, 2026 /PRNewswire/ -- USA News Group News Commentary - The post-quantum cryptography industry has moved from research topic to procurement line item over the past two years, and forecasters expect that shift to accelerate. Markets and Markets projects the global post-quantum cryptography market growing from roughly $0.42 billion in 2025 to about $2.84 billion by 2030, a compound annual growth rate near 46%. Active Companies from around the markets with current developments this week include: QSE - Quantum Secure Encryption Corp. (CSE: QSE) (OTCQB: QSEGF) (FSE: VN80), IonQ, Inc. (NYSE: IONQ), D-Wave Quantum Inc. (NASDAQ: QBTS), Rigetti Computing, Inc. (NASDAQ: RGTI), Arqit Quantum Inc. (NASDAQ: ARQQ).

The firm attributes the urgency to rising cyber threats and the risk of quantum-enabled attacks, which together are pushing organizations to replace vulnerable public key cryptography with quantum-safe alternatives for the sake of data protection, compliance and enterprise resilience, with government-backed standardization accelerating the transition.

Other forecasters size the opportunity differently but point the same direction. Mordor Intelligence puts the market nearer $0.88 billion in 2025 and $4.60 billion by 2030, attributing the pace to regulatory urgency, the first three NIST standards and rapid federal budget allocations moving procurement cycles across government, defence and critical-infrastructure operators. The common thread across the forecasts is that statutory migration deadlines, rather than product enthusiasm, are what generate the early demand.
