According to our latest study on "Data Bus Market Size and Forecast (2021-2031), Global and Regional Share, Trends, and Growth Opportunity Analysis - by Component, Hardware Type, Type, Application, and Geography," the data bus market size was valued at US$ 22.51 billion in 2024 and is anticipated to reach US$ 32.07 billion by 2031. The data bus market is estimated to record a CAGR of 5.3% from 2025 to 2031.

Increasing Adoption of Industrial Automation to Boost Data Bus Market Growth During Forecast Period

The rapid adoption of Industry 4.0 technologies, particularly within smart manufacturing and industrial automation, is expected to create a demand for data buses. As factories increasingly transition toward digitally integrated, data-driven operations, there is a rising need for efficient, real-time data transfer mechanisms. This environment necessitates high-performance data bus systems capable of supporting the massive volumes of information exchanged between machines, sensors, controllers, and cloud-based platforms. This trend is underscored by findings from Rockwell Automation's 10th annual "State of Smart Manufacturing Report," released in June 2025. The report, which surveyed over 1,500 manufacturers across 17 leading industrialized nations, revealed that 81% of manufacturers are facing growing internal and external pressures that are accelerating their digital transformation strategies. Among the top areas for technology investment are cloud/SaaS platforms, artificial intelligence (AI), cybersecurity, and quality management-all of which rely heavily on seamless and secure data communication infrastructures. These findings highlight a significant need for robust data bus architectures that can handle both high-speed data transmission and system interoperability in increasingly complex manufacturing environments.

Furthermore, the report indicates that 95% of manufacturers have either invested in or plan to invest in AI and machine learning (ML) technologies over the next five years. As AI adoption shifts from experimentation to strategic deployment, particularly in applications such as generative and causal AI, the necessity for data buses capable of supporting real-time analytics, predictive maintenance, and closed-loop control systems becomes even more evident. These advanced systems depend on the reliable transmission of large volumes of data across edge devices, programmable logic controllers (PLCs), and centralized analytics engines, making modern data bus solutions essential. As industrial facilities modernize their infrastructure, the deployment of scalable, high-bandwidth, and low-latency data buses will be crucial to achieving the full potential of Industry 4.0. This creates a substantial market opportunity not only for traditional data bus technologies such as CAN, Modbus, and PROFIBUS but also for emerging solutions tailored to hybrid and cloud-connected environments.
