According to Straits Research, the global mainframe modernization market size was valued at $8.23 billion in 2025 and is projected to reach $18.42 billion by 2034, registering a CAGR of 9.5% during the forecast period 2026–2034.
The mainframe modernization market is fueled by the increased need for digital transformation throughout enterprises dependent on legacy IT infrastructures. Firms are increasingly moving towards cloud-native architecture, containerized environments, and API-led integration for enhancing operational efficiency and minimizing the elevated maintenance expenses associated with conventional mainframes. The necessity to elevate application agility, harden cybersecurity, and handle real-time data processing is driving modernization efforts throughout key industries like BFSI, government, retail, and telecommunication.
Persistent government and regulatory urgency to modernize legacy infrastructure—particularly in financial services and public sector institutions—is serving as a strong growth catalyst. Also, companies are increasingly implementing automated code conversion tools, AI-powered refactoring, and hybrid cloud deployment patterns to reduce migration risks and downtime. Strategic investments in modernization services, vendor-promoted transformation frameworks, and mainframe-to-cloud managed services are unleashing revenue streams for technology vendors globally.
