Equinix operates the world's largest network of colocation data centers, providing physical space, power, and connectivity for the IT infrastructure of enterprises, cloud providers, and network operators. Its defining asset is Platform Equinix—a globally interconnected network of facilities where customers co-locate servers and connect directly to cloud providers, internet exchanges, and each other over private cross-connects.

AI has shifted the requirements of data center colocation in ways that favor Equinix's positioning. Enterprises building AI applications need infrastructure close to their existing data and low-latency access to the cloud services running foundation models. Equinix facilities—at the intersection of enterprise colocation and cloud connectivity—are natural locations for AI inference infrastructure. The power density requirements of AI GPU hardware have also created demand for premium colocation space capable of supporting high-wattage racks.

Equinix launched AI Infrastructure by Equinix (AIE) in 2025, offering managed GPU clusters as a colocation service. The company announced a joint venture exceeding $15B to develop AI-optimized data centers. Annual revenue reached approximately $9.2B in FY2026, with record leasing activity driven by hyperscaler and enterprise AI capacity demand.
