Operational Technology Market Set to Surge to USD 364.74 Billion by 2030

The Operational Technology (OT) market is poised for significant growth, projected to reach USD 364.74 billion by 2030, according to a report by DataM Intelligence. The market was valued at approximately USD 210.06 billion in 2024, indicating a robust compound annual growth rate (CAGR) of 9.6% from 2025 to 2030. This expansion is driven by the increasing convergence of OT and Information Technology (IT), along with the rising adoption of the Industrial Internet of Things (IIoT) and advanced automation technologies.

As industries modernize their operations, sectors such as manufacturing, energy, oil and gas, and pharmaceuticals are transforming their legacy OT systems. This modernization aims to enhance reliability, reduce downtime, and improve worker safety through predictive maintenance and real-time analytics. The ongoing shift towards smarter, connected industrial control systems is crucial for advancing towards the next phase of Industry 4.0, characterized by digital twins, edge intelligence, and autonomous operations.

Key Drivers of OT Market Expansion

Several factors are propelling the growth of the OT market. Notable among these are the increasing risks associated with cyber-physical systems, which have led to stronger cybersecurity mandates. The expansion of 5G technology is facilitating the deployment of IIoT in factories and energy infrastructures. Additionally, the implementation of AI-driven predictive maintenance can reduce unplanned downtime by 25-40%, while the demand for operational resilience and energy efficiency continues to rise.

Manufacturers are increasingly shifting from traditional supervisory control and data acquisition (SCADA) systems to more advanced distributed control systems. This transition is essential as industries evolve towards autonomous and semi-autonomous production environments, solidifying OT’s role as one of the fastest-growing segments in industrial digitalization.
