Initial market spending on PQC kicked off in 2020-2022 in the defense space, in automotive and aeronautics OEMs, and in supporting semiconductor markets, notably highly-critical markets (national security) and in those with long product life spans. Market uptake will accelerate significantly between 2026 and 2028, as organizations increase spending on PQC solutions in order to align with national migration policy requirements for PQC readiness by 2030. The brunt of the spending there will be by critical infrastructure and other regulated sectors.
