Post-quantum cryptography market to exceed $13 billion by 2035 as Q-Day awareness accelerates

A new study by global tech strategists Juniper Research has found that the post-quantum cryptography market will grow from $1.2 billion in 2026 to $13 billion in 2035; representing a high CAGR of 30%.

The research identifies two primary forces driving this growth: the rapid evolution of standards and regulations designed to prepare for ‘Q-Day’, and sustained R&D investment that is accelerating algorithm maturity through rigorous, real-world testing.

‘Q-Day’ – the point at which quantum computers can compromise today’s encryption – is firmly on the radar of governments and forward-thinking organisations; however, awareness remains the biggest obstacle. “Many businesses still underestimate the risk of quantum-enabled attacks; making clearer, more accessible education critical to securing internal buy-in,” explained Louis Atkin, Research Analyst at Juniper Research.

Collaboration Between Organisations Crucial for Maintaining Security

The research identified that global collaboration between organisations will be critical for the technology to be adopted effectively. Cryptography is a technological domain which is heavily reliant on interoperability across infrastructure, with many systems required to operate across borders.

“Many countries have accepted NIST’s standardised algorithms as the de facto quantum-safe option, even in nations with limited understanding of the quantum landscape. It is vital this continues and that different sectors consider how their systems interoperate when implementing quantum-safe solutions,” Atkin concluded.
