Post-Quantum Security Market Forecast to Grow 46% a Year to 2030

VANCOUVER, BC, Sept. 30, 2026 /PRNewswire/ -- American News Group News Commentary - The encryption protecting today's data has a shelf life, and the market for replacing it is starting from a small base. MarketsandMarkets projects the global post-quantum cryptography market will grow from $0.42 billion in 2025 to $2.84 billion by 2030, a compound annual growth rate of 46.2%. Active Companies from around the markets with current developments this week include: Quantum Secure Encryption Corp. (CSE: QSE) (OTCQB: QSEGF) (FSE: VN80), Cloudflare, Inc. (NYSE: NET), IonQ, Inc. (NYSE: IONQ), Akamai Technologies, Inc. (Nasdaq: AKAM) and Okta, Inc. (Nasdaq: OKTA).

The concern behind that growth is simple. Data captured and stored today could be decrypted later by a sufficiently powerful quantum computer, which is why security teams are being asked to plan the migration now, before such machines exist. Standards work has moved from theory to product: the U.S. National Institute of Standards and Technology has published FIPS 203, the module-lattice key encapsulation standard that hybrid key exchanges in current browsers and networks build on.

The forecast is a third-party projection, not a guarantee, and timelines for quantum capability remain debated. What is not debated is that large infrastructure vendors have started publishing migration dates, and that quantum hardware companies are reporting rapid revenue growth off small bases, which together put post-quantum readiness on more enterprise agendas.
