AI Clusters Push Data Center Cables Market to $27.29B by 2035
London – October 06, 2026 -- The global Data Center Cables Market was valued at $10.65 billion in 2025 and is projected to reach $27.29 billion by 2035, a 9.87% compound annual growth rate, as AI clusters more than double the cabling spend per megawatt compared with conventional facilities, according to a new study from DC Market Insights.
AI Data Halls Carry $1.07 Million in Cabling Per MW
An AI-oriented data hall carried about $1.07 million of cabling content per MW in 2025, versus approximately $0.43 million per MW for a conventional facility. AI facilities accounted for an estimated 35% of new capacity in 2025, a share projected to rise to 66% by 2035. Some AI rack configurations now require inter-rack connectivity exceeding 3,000 fibers, driving demand for smaller-diameter, higher-density fiber systems and pre-terminated assemblies that preserve airflow in dense environments.
