Data Center Copper Electrical Materials Market Size, Share & Forecast to 2035

The Data Center Copper Electrical Materials Market is valued at USD 6.09 billion in 2026 and is projected to reach USD 10.85 billion by 2035, up from USD 3.79 billion in 2025, a CAGR of 11.08% from 2025 to 2035 (DC Market Insights estimate). Two numbers move the money here: the tonnes of copper each megawatt of new capacity locks into cable, busbar, switchgear windings and earthing grids, and the London Metal Exchange (LME) price at which that metal is bought. Microsoft’s Chicago data center used 2,177 tonnes of copper, or 27 tonnes per megawatt (MW) of applied power, according to BHP, while the World Bank put the 2026 LME copper average at about USD 13,539 per tonne for January to October, 36% above the 2025 average of USD 9,947. The 2025 receipt is 12,000 MW of new IT capacity × 26.19 tonnes of electrical copper per MW = 314.3 thousand tonnes, plus 116 GW of installed capacity × 0.25 tonnes per MW for refresh and retrofits = 29.0 thousand tonnes, a total of 343.3 thousand tonnes × USD 11,047 per tonne (LME USD 9,947 plus USD 1,100 fabrication premium) = USD 3.79 billion. DC Distribution grows fastest at 29.81% a year as 800-volt direct current racks arrive, and the Middle East and Africa is the fastest region at 14.89%, led by new-build campuses in Saudi Arabia growing 16.79% a year.

• Intensity falls slowly, because 800 VDC cuts rack-level copper by 45% (NVIDIA): copper per new MW slips from 26.19 to 25.10 tonnes by 2035.

Executive Summary: What Is the Data Center Copper Electrical Materials Market Worth?

The Global Data Center Copper Electrical Materials Market size was valued at USD 976.03 million in 2020, reached USD 3.79 billion in 2025, and is anticipated to reach USD 10.85 billion by 2035, at a CAGR of 11.08% during the forecast period.

Growth in the Data Center Copper Electrical Materials Market averaged 31.19% a year from 2020 to 2025, as new IT capacity rose from 4.6 GW to 12.0 GW and the copper price rose from USD 6,174 to USD 9,947 per tonne on the World Bank Pink Sheet. From 2026 the pace settles at 11.08% a year: tonnage grows 8.21% a year as completions approach 27 GW in 2035, while DC Market Insights assumes the price eases from about USD 13,600 in 2026 to USD 12,000 in 2030 before tracking inflation.

What Does the Data Center Copper Electrical Materials Market Include?

The Data Center Copper Electrical Materials Market covers USD 3.79 billion of 2025 spending on the copper metal that goes into a data center’s power path and earthing, valued at the LME price plus the premium for rod, wire, busbar, strip and stranded conductor.

Included

• Copper conductor in medium and low voltage power cable, building wire and metal-clad cable inside the site
• Copper busbar and busway trunking, switchgear busbars and transformer, generator, UPS and motor windings
• Earthing grids, bonding conductors, lightning protection and grounding busbars
• In-rack busbars, power shelves and power cords up to the server power supply

Excluded

• The value added by cable insulation, enclosures and assembly, covered in the Data Center Power Cable Market and the Data Center Busway Market
• Copper foil in server printed circuit boards and copper signal cables between accelerators, covered in the AI Server Copper Foil Market
• Copper in plumbing, cooling coils and heat exchangers (about 3% of data center copper)
• Copper in utility substations and transmission lines outside the site fence

How the segments fit together

Each segment dimension of the Data Center Copper Electrical Materials Market sums to the same USD 3.79 billion in 2025: the application view splits it by electrical system, the product-form view by the copper semi-product bought, the data-center-type view by buyer and the voltage view by distribution level.

Why Do Data Center Copper Electrical Materials Market Estimates Differ?

Estimates for copper in data centers differ because some count every tonne in the building and its IT, while the DC Market Insights figure of USD 6.09 billion for 2026 counts only electrical copper inside the fence, at metal-plus-fabrication value.

BHP puts all data center copper at about 0.5 million tonnes a year today, rising six-fold to about 3 million tonnes by 2050; that wider total includes copper inside servers, network gear and connections to the grid. Other definitions price copper at the finished value of cable and switchgear, which adds insulation, enclosure and assembly value to the metal, or add plumbing and cooling copper. This edition keeps 343.3 thousand tonnes in 2025, or about 69% of BHP’s total. Smaller buyers sit inside the scope: enterprise and edge sites, regional colocation operators and electrical contractors buying rod and wire for them.

Market Drivers: Why Is Data Center Copper Spend Rising?

Three forces add USD 4.36 billion to the Data Center Copper Electrical Materials Market between 2025 and 2030: a record copper price, electrical suppliers’ data center order books and United States tariffs that reroute where rod and wire are made.

LME Copper Averages About USD 13,539 per Tonne in 2026

The World Bank’s monthly series shows copper at USD 13,012 per tonne in January 2026 and USD 14,508 in October, an average of about USD 13,539, against USD 9,947 for 2025. Because data center buyers pay for copper on a pass-through basis, the price step alone adds about USD 1.50 billion to the Data Center Copper Electrical Materials Market in 2026 on 411.8 thousand tonnes. The United States Geological Survey (USGS) reported a record 2025 COMEX average of USD 4.80 per pound, about USD 10,580 per tonne, in its Mineral Commodity Summaries 2026.

Legrand Data Center Sales Reach EUR 2.4 Billion, 26% of Revenue

Data center sales at Legrand, which makes Starline busways, reached EUR 2.4 billion or 26% of group sales in 2025, up from EUR 0.7 billion in 2020, according to its full-year 2025 results. Eaton reported Electrical Americas data center orders up about 200% and data center revenue up about 40% in the fourth quarter of 2025, and Vertiv ended 2025 with a USD 15.0 billion backlog. Each of these orders carries copper: DC Market Insights counts 26.19 tonnes of electrical copper per new MW, so the 14.5 GW completed in 2026 needs about 380 thousand tonnes.

Section 232 Tariff of 50% Moves Rod and Wire Production Into the United States

Proclamation 10962 of 30 July 2025 placed a 50% tariff on semi-finished copper products and copper-intensive derivatives such as cables and electrical components from 1 August 2025, according to the Federal Register, and a proclamation of 2 April 2026 applied the duty to full customs value from 6 April 2026. United States copper demand from data centers, USD 1.54 billion in 2025, is therefore served more by domestic rod mills: Prysmian is spending more than EUR 700 million at Encore Wire in McKinney, Texas, on a second rod mill and metal-clad cable for data centers, and Southwire is investing more than USD 256 million in Starkville, Mississippi.

Market Trends: How Is Copper Use per Megawatt Changing?

Copper per new MW in the Data Center Copper Electrical Materials Market falls from 26.19 tonnes in 2025 to 25.10 tonnes in 2035 (DC Market Insights estimate), as higher voltages thin the conductors while busway takes share from cable.

NVIDIA’s 800 VDC Design Cuts Rack Copper by 45%

A 1 MW rack fed at 54 volts direct current needs up to 200 kilograms of copper busbar, and an 800-volt direct current (VDC) design reduces copper requirements by 45%, according to NVIDIA’s May 2025 architecture paper. DC Market Insights applies that saving to the rack and row layer, about 20% of electrical copper, on 70% of AI capacity by 2035, so DC Distribution grows from USD 151.69 million in 2025 to USD 2.06 billion by 2035 while total intensity falls only 4.2%.

Busduct Revenue at LS Eco Energy Tripled in the First Half of 2026

LS Eco Energy said busduct revenue more than tripled year on year in the first half of 2026 and is investing about KRW 8 billion in Vietnam to double its busduct capacity from the second half of 2027. Busway and Busbar Trunking in the Data Center Copper Electrical Materials Market grows at 14.33% a year, the fastest application, because overhead busway replaces runs of parallel cable in high-density AI halls.

Market Challenges: What Makes Copper Hard to Budget for Data Centers?

Price swings and thrifting are the two main risks to the Data Center Copper Electrical Materials Market: a 10% move in the copper price changes 2026 value by about USD 560.04 million.

Metal Price Swings Pass Straight to Buyers

Cable makers report at fixed standard copper prices, EUR 5,500 per tonne at Prysmian and EUR 5,000 at Nexans, and pass the difference to customers through metal adjustment clauses. Schneider Electric reported about EUR 0.9 billion of copper within its 2025 costs. For a 100 MW campus the USD 38.76 million copper bill at 2026 prices moved by about USD 11.95 million between the 2025 average of USD 9,947 and the October 2026 price of USD 14,508 per tonne (DC Market Insights estimate).

Tariffs Split the United States Price From the World Price

The COMEX average of USD 4.80 per pound in 2025 sat about 9% above the LME cash average of USD 4.40 reported by the USGS, and the April 2026 change to full customs value widened the gap for imported cable and busway. Buyers in the United States, 40.7% of the 2025 market, carry that premium on every imported tonne.

Market Opportunities: Where Will Data Center Copper Demand Grow Most?

Two opportunities stand out in the Data Center Copper Electrical Materials Market: busbar profiles for AI halls and new campuses in India and Saudi Arabia, together worth USD 3.48 billion by 2035 (the groups overlap only where Indian and Saudi sites buy busbar).

Busbar Profiles and Shapes Worth USD 2.60 billion by 2035

Busbar Profiles and Shapes grow from USD 720.52 million in 2025 at 13.71% a year. Aurubis produced 175,000 tonnes of shapes in fiscal 2024/25, and Mitsubishi Materials targets oxygen-free copper for data center and AI busbars, so producers of high-conductivity flat products gain the most from busway and switchgear demand.

India and Saudi Arabia Add USD 707.07 million

India grows from USD 117.56 million to USD 627.10 million at 18.22% a year, and Saudi Arabia from USD 53.09 million to USD 250.62 million at 16.79%, the two fastest large countries in the Data Center Copper Electrical Materials Market. Both build mostly new campuses, so nearly all demand is first-fit copper at 25.70 tonnes per MW rather than replacement.

Pricing: What Does Copper Cost per Tonne and per MW in Data Centers?

Delivered electrical copper for data centers costs USD 14,800 per tonne in 2026 (DC Market Insights estimate), or about USD 0.39 million per MW of new IT capacity.

Public anchors: the World Bank LME series for 2020 to 2026, the USGS COMEX average of USD 4.80 per pound for 2025, and the standard copper prices of EUR 5,500 and EUR 5,000 per tonne used by Prysmian and Nexans. Fabrication premiums blend wire rod with busbar and strip and are DC Market Insights estimates; 2027-2035 LME values are DC Market Insights assumptions, not forecasts by the sources named.

Standards and Regulation: Which Rules Shape Copper Use in Data Centers?

Trade rules and wiring codes govern the Data Center Copper Electrical Materials Market: three United States proclamations between July 2025 and June 2026 set copper import duties, while electrical codes fix how much conductor and earthing each site needs.

• Proclamation 10962 (30 July 2025): 50% tariff on semi-finished copper products and copper-intensive derivatives from 1 August 2025, with a phased refined-copper duty of 15% from 2027 and 30% from 2028 left open (Source: Federal Register).
• Proclamation of 2 April 2026: duties on copper articles apply to full customs value from 6 April 2026, at 50%, 25% or 10% depending on the annex and on United States smelting (Source: The White House).
• Proclamation 11032 (1 June 2026): the threshold for goods made of United States metal falls from 95% to 85% (Source: Federal Register).
• EU Critical Raw Materials Act, Regulation (EU) 2024/1252: copper is listed as a strategic raw material (Source: European Commission Joint Research Centre).
• National Electrical Code (NFPA 70), Article 250, and IEC 60364-5-54 set grounding and bonding conductor sizes, which drive the 22.7% earthing share.
• IEC 60228 conductor classes and ASTM B187 for copper bus bar set the conductor grades used in cable and busway.

Research Methodology: How DC Market Insights Sized the Data Center Copper Electrical Materials Market

DC Market Insights sized the Data Center Copper Electrical Materials Market bottom-up at USD 3.79 billion for 2025 from tonnes per MW and the copper price, with three bound checks; the full approach is set out in our research methodology.

• Capacity: new IT capacity of 12.0 GW in 2025, 22 GW in 2030 and 27 GW in 2035; installed base 116 GW in 2025 and 311 GW in 2035.
• Intensity: 27 tonnes per MW (BHP) × 97% electrical share (Copper Development Association) = 26.19 tonnes; 800 VDC removes 45% of the rack and row layer (20% of copper) on 0% of AI capacity in 2026, 35% in 2030 and 70% in 2035; replacement 0.25 tonnes per installed MW-year.
• Price: World Bank LME averages 2020-2025, USD 13,600 for 2026, USD 12,000 for 2030 and +1.5% a year after; fabrication premium USD 1,100 per tonne in 2025, +2% a year from USD 1,200 in 2026.
• Bound check 1 (ceiling): 343.3 thousand tonnes in 2025 is about 69% of BHP’s estimate of about 0.5 million tonnes for all data center copper, which also counts IT equipment.
• Bound check 2 (ceiling): the same tonnage is 1.18% of the 29.0 million tonnes of world refined copper output in 2025 reported by the USGS, close to BHP’s 1% digital share of demand.
• Bound check 3 (floor): copper in power cable, USD 1.14 billion, is 65% of the USD 1.74 billion DC Market Insights Data Center Power Cable Market in 2025, consistent with copper’s share of low and medium voltage cable value at 2025 prices.
• Splits: every segment, region and country split sums to the total in every year from 2020 to 2035; CAGRs are recomputed from endpoint values.
