The global IT Business-to-Business (B2B) market is expected to reach a value of $6.7 trillion by 2025, driven by growth across sectors such as data centers, IT services, public cloud, cybersecurity, and emerging technologies like artificial intelligence (AI) and the Internet of Things (IoT). This reflects a significant expansion from $3.7 trillion in 2019, with the market projected to grow by approximately 10% year-over-year, according to data from AltIndex.com.
The IT B2B sector includes major technology vendors and service providers such as Microsoft, IBM, Oracle, and cloud providers Amazon Web Services, Microsoft Azure, and Google Cloud. Cybersecurity firms like Fortinet and CrowdStrike, along with AI-focused companies such as Nvidia, also play a central role in this industry. Although the sector is global, a substantial share of revenues is concentrated in just five countries—the United States, China, Japan, Germany, and the United Kingdom. Together, these countries generated 56% of the global IT B2B revenue, or $3.07 trillion, in 2023. By 2025, this figure is expected to rise to nearly $3.7 trillion.
The United States leads the market, with forecasted IT B2B revenues of $1.9 trillion in 2025. China follows with expected revenues of $963 billion, driven by rapid growth in various technologies. Japan, the United Kingdom, and Germany are also major contributors, with projected revenues of $339 billion, $259 billion, and $246 billion, respectively, by 2025.
Among the fastest-growing segments are AI and IoT, which are expected to achieve a compound annual growth rate (CAGR) of 26% between 2019 and 2025. This is more than double the growth rate of the overall market, spurred by increasing demand for automation and advances in data processing and integration. The public cloud sector is also seeing substantial growth, with a forecasted 25% CAGR during the same period. In contrast, more mature markets like communication services and devices are growing at much slower rates, with CAGRs of just 2% and 1%, respectively.
As businesses across industries increasingly rely on these technologies for efficient operations, competition, and innovation, the IT B2B market is poised for continued growth in the years ahead.
