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.
Fiber Optic Cables Hold Nearly Half of Global Spending
Fiber optic cables generated an estimated $5.07 billion in 2025, representing 47.6% of the market, and are forecast to reach $15.94 billion by 2035 at a 12.14% CAGR. Copper cables held 31.4% of 2025 spending and power cables 21.0%. Hyperscale data centers were the largest buyer category at approximately $4.95 billion, or 46.5% of demand, followed by colocation at 25.3%, enterprise at 18.4% and GPU and neocloud providers at 9.8%. GPU and neocloud buyers are the fastest-growing segment, with spending advancing at a 12.21% CAGR through 2035. High-speed Ethernet and GPU fabric connectivity reached roughly $2.92 billion in 2025 and is projected to hit $10.40 billion by 2035, overtaking conventional networking connectivity before the decade's end.
North America Leads but Asia Pacific Gains Fastest
North America accounted for 42.6% of global revenue in 2025, or approximately $4.54 billion, rising to roughly $10.75 billion by 2035, though its global share is expected to gradually decline. Asia Pacific held 27.9% of demand, equivalent to $2.97 billion, and is forecast to reach $8.51 billion by 2035 at an 11.10% CAGR, the strongest share gain among major regions. Europe held 18.7%, Latin America 5.6% and the Middle East and Africa 5.2%, with the latter projected as the fastest-growing region at an 11.45% CAGR on the back of sovereign AI programs in Saudi Arabia and the United Arab Emirates. The United States represented 37.6% of global spending, the largest national market, followed by China, while India is expected to post the strongest national CAGR at 14.32% through 2035, closely trailed by Malaysia.
Amphenol, Corning and Prysmian Lock In Multiyear Supply Deals
Amphenol completed a $10.5 billion acquisition of CommScope's Connectivity and Cable Solutions business in January 2026. The same month, Corning and Meta announced a multiyear agreement worth up to $6 billion covering optical fiber, cable and connectivity. Prysmian signed an agreement worth up to €5.5 billion with Molex in July 2026 to supply fiber cables for data center applications, alongside a €1.25 billion commitment through 2031 to expand U.S. fiber capacity. New construction accounted for 73.8% of cable spending in 2025, with DC Market Insights modeling annual IT capacity additions rising from approximately 12.0 GW in 2025 to 27.0 GW in 2035.
DC Market Insights' base-case forecast places the market at $27.29 billion by 2035, with a lower-growth scenario at approximately $22.90 billion and a stronger investment scenario reaching about $31.35 billion. Beyond new construction, the installed base will require periodic cabling upgrades as architectures transition from 400G to 800G and 1.6T, creating a recurring refresh market alongside greenfield demand.
