Cable Industry Outlook 2026: Electrification, Data Centres & Copper

Market size and momentum

The global wire & cable market is estimated at roughly US$245 billion in 2026, growing at about a 6% compound annual rate. Demand is broad-based: metallic power cable, structured data cable and optical fibre are all rising as economies electrify and digitise. (Market sizing per published 2026 industry reviews — see CRU and sector market reports.)

The data-centre boom

AI and cloud build-out has made data centres the fastest-growing cable application, now estimated at around 8% of US metallic-cable demand and climbing. The pull is twofold: heavy power distribution cable for rising rack densities, and large volumes of high-performance data and fibre-optic cable for interconnect.

Electrification: EVs, grid and renewables

• EVs & charging — each battery-electric vehicle carries 3–4× the copper wiring of a combustion car, driving demand for automotive and EV charging cable.
• Grid modernisation — with the IEA estimating ~US$2 trillion a year of grid spend, MV and overhead-line demand is structural.
• Renewables — wind and solar lift demand for PV string cable, turbine cable and HV collector cable.

Copper, aluminium and what it means for sourcing

Copper still holds the majority of conductor volume (~58%), but aluminium is growing faster as buyers manage cost and weight. For sourcing teams the practical takeaways are: budget cable against the live copper price (see our copper & cable cost briefing), specify the governing standard up front, and consolidate enquiries so quotes reflect real metal content and lead time.
