Surging demand for AI-driven datacenters is sparking record investments in semiconductor plants worldwide. Analysts project capacity to spike through 2026, with hyperscalers leading the charge. From Northern Virginia to Asia’s tech hubs, billions are being poured into fabs and infrastructure, reshaping the global chip industry and powering AI’s relentless growth.

The global race to build the backbone of artificial intelligence has shifted into overdrive. As AI workloads multiply across datacenters, semiconductor manufacturers are responding with unprecedented investments in new fabrication plants, capacity expansions, and advanced chip technologies.

According to Gartner, global AI spending is expected to exceed $2 trillion by 2026, driven largely by hyperscaler investments in AI-optimized datacenters and GPUs. This surge is fueling demand for cutting-edge chips, pushing manufacturers to accelerate plant construction and capacity upgrades.

A McKinsey report highlights that by 2030, datacenter investments could reach $6.7 trillion globally, with AI workloads accounting for nearly 70% of total compute demand. Capacity for AI-specific tasks is projected to grow 3.5 times, underscoring the scale of infrastructure required to sustain machine learning, generative AI, and large language models.

Meanwhile, industry observers note that 2025 has already been a transformative year. The Empiric Data Centre Boom report points to rapid construction in the United States, particularly in Northern Virginia, Texas, and Oregon, where power availability and connectivity make them prime hubs. Similar expansions are underway in Asia and Europe, intensifying global competition for talent, resources, and supply chain resilience.
