Market Overview

Market Value Projected to Reach USD 10.88 Billion by 2035

In 2025, the global data center busways market is valued at USD 3.15 billion. By 2035, driven by AI-powered rack power density that is transforming electrical distribution architecture, the market will grow to about USD 10.88 billion. The compound growth rate will be nearly 3.5 times in the coming decade. That trajectory tracks closely with what is happening one level up in the value chain. As described in more detail shortly, combined capital spending of hyperscalers has spiked significantly in a single year from 2025 to 2026, and the demand for busways is a downstream component of capital spending.

Key Insight: Dollars spent on busways in projects like these used USD 3.15 billion and account for a small portion of the much larger capital expenditures. A projected 3.5 times expansion over ten years lines up directionally with the even sharper single-year jump already visible in hyperscaler capital spending, since busway demand really is downstream of that bigger spending cycle.

Above-1,250A Busways Post the Fastest Growth as AI Racks Scale Up

Per-rack power demand is likely to build significantly toward its above 1250A segment in the data center busway market, which is expected to hold 23% of market share in 2035, further growing at a CAGR of 17.6%. This is facilitated by the AI accelerators that use specified power demand, which is significantly greater than what's traditionally used by IT loads. The direction of the shift alone is worth noting here, though, since the highest capacity tier is set to grow nearly twice as fast as the lowest one.

Key Insight: The highest power rating tier that is above 1250A is growing at close to double the pace of the lowest one with 17.6% CAGR, a gap that lines up directly with AI racks now drawing far more power than busways were originally designed to handle.

Fastest Growth Clusters Around AI-Scale Power Capacity and Smart Monitoring

Monitoring & communications modules is the fastest-growing segment, growing at 18.6% CAGR during 2025-2035, followed by above 1,250A power rating at 17.6%, hyperscale data centers at 17.5%, cloud service providers at 16.5%, and medium voltage at 16.2%. The ranking indicates that the increase isn't solely on the basis of power capacity. AI workloads are not only putting pressure on rack-level power consumption, but are also driving the growth of hyperscale data centers and the need for real-time monitoring and communication. For busway systems that support increasingly heavy electrical loads, operators are increasingly seeking to see when and where power flows, how well systems perform, and how they are utilized. This is driving the market to busways that are designed to deliver high current and smarter monitoring.

Key Insight: The fastest-growing sub-segment in this entire market is a monitoring and communication component, not raw power capacity, which fits a broader shift from busways as a hardware product toward a software enabled infrastructure platform.

North America: 37% Share in 2025, Declining to 34% by 2035

North America continued to lead the region with 37% in 2025, due to its proven hyperscale data center footprint and ongoing investments made by hyperscale cloud providers. It is estimated that the market will grow at 11.8% CAGR globally, while the region will see a decline to 34% by 2035. The lower share growth is due to the relatively mature data center infrastructure in North America, seeing more busway demand from upgrades and capacity expansions as well as from AI retrofits. Meanwhile, AI workloads are growing at the same time, yet there continues to be a need for higher current busways and power distribution upgrades throughout the facility.

Key Insights: North America is the largest established market, but the regions having the fastest growth in infrastructure expansion slowly diminish the regional share of North America.

Source: Precedence Research Database

Europe: 24% Share in 2025, Declining to 22% by 2035

Europe's policies and plans for green data centers continue to accelerate infrastructure modernization in the region, resulting in the second-largest regional share in 2025 of 24%. The percentage decreases to 22% by 2035 when taking into account the region's population growth rate of 11.2% per year, which is the slowest of the three major regions, such as North America and Asia Pacific.

Key Insight: Europe's 11.2% share growth rate is lower than the market's 13.2% market average, so the region will lose its share of the market by 2035.

Source: Precedence Research Database

Asia-Pacific: 30% Share in 2025, Growing to 37% by 2035

AI adoption, cloud expansion, and hyperscale construction for services in Asia-Pacific are boosting it to be the fastest-growing region in this market in 2025, with a 30% market share already acquired. By 2035, its share rises to 37% on a 16.4% CAGR, which is higher than the world average.

Key Insight: Asia-Pacific, with 16.4% growth over the course of the market, is expected to increase its share in the global domain over time till 2035.

Latin America: 5.0% Share in 2025, Declining to 4.0% by 2035

Latin America's share of global had modestly grow to 5% in 2025, and with continued investments in colocation facilities, the market is witnessing expansion contributed by various countries in the region. The share declines to 4% by 2035 as the region expands at 12.6% annually.

Key Insight: Latin America loses its share in the globe through 2035, which is comparable to the region's growth of 12.6%, compared with the market's 13.2% global growth.

Source: Precedence Research Database

Middle East & Africa: 4% Share in 2025, Declining to 3% by 2035

I interpret that, by 2025, the Middle East and Africa region had the smallest representation at 4%, although smart city projects and overall IT transformation provided some growth in the region. The data centers deployed across the region's smart cities are still a gradual part. The market share is expected to reduce to 3% by 2035, with 12.9% CAGR during the projected period.

Key Insight: The Middle East and Africa region forgoes global share through 2035 with 12.9% CAGR growth compared with the market's global average of 13.2%.

Source: Precedence Research Database

Hyperscaler Capital Expenditure Is Set to Grow 77% in a Single Year

I found that the primary demand driver behind this entire market, hyperscale and AI infrastructure investment, is not just a narrative but a genuinely quantifiable and fast-accelerating trend. The four biggest U.S. hyperscalers, including Amazon, Alphabet (owner of Google), Meta, and Microsoft, collectively announced that they expect to spend USD 725 billion on capital expenses in 2026, which's 77% higher than the capital expenditures estimated at around USD 410 billion for 2025. Among all of these, Amazon accounts for USD 200 billion, Alphabet for USD 175 to 185 billion, Meta for USD 115 to 135 billion, and Microsoft for USD 110 to 120 billion, and Goldman Sachs estimated that the capital expenditure for all the hyperscalers equals USD 5.3 trillion between FY 2025 and FY 2030.

Key Insight: The capital spending increase will eventually enable new data center builds and therefore the installation of new busways. This is in excess of this market's forecast capital expenditure growth of 13.2%, suggesting that the forecast may be conservative if hyperscaler capital expenditure guidance actually comes through.

AI Racks Now Draw Up to 79x the Industry-Average Rack

The most notable technical explanation behind the fastest-growing power rating tier, as part of modern AI accelerator racks, is now being scaled in massive quantities. According to the Uptime Institute's 2025 data for the industry average data center rack, it consumes only 7.6 kilowatts. The H100 air-cooled AI rack consumes about 40 kilowatts of power, while the NVIDIA GB200 NVL72 rack, which will be deployed in 2024 and 2025.

Consumes about 120 kilowatts nominal, with measured values of 130 to 132 kilowatts being applied through an integrated server DC power supply. Subsequently called a common DC power supply rather than through individual power supplies. A new line of NVIDIA GPUs, known as the Blackwell Ultra (GB300) series, is scheduled for release in 2025, consuming 135 to 142 kilowatts, while another generation from NVIDIA would be a platform. They will be called Vera Rubin NVL144, expected to be available at large volume in 2026, and would require closer to 600 kilowatts per rack.

Key Insight: With NVIDIA's very own new rack platforms, the company has actively made use of a common busbar instead of a single server power supply. Showing, meaning busway architecture is not merely accommodating rising AI power density. It has become structurally required by the chip platforms themselves.

Legrand's Record 2025 Results Are Explicitly Attributed to Data Centers

Aman interpreted by looking at named manufacturer financial results to see whether this market's growth story shows up in actual audited numbers, not just analyst projections. Legrand's 2025 financials don't disappoint. For the year, the company reported record revenue growth of 13%, of which the growth was directly attributed to data centers and acquisitions at 7.7% and 5.1%, respectively. Adjusted operating margin was achieved at 20.7% on the back of acquisitions. Starline, the dedicated data center busway brand, posted a standalone brand revenue of around USD 19.4 million for the year.

Key Insight: That a top-tier global busway maker made a specific 13% record revenue year, brazenly reported to explicitly credit data centers, is audited revenue, rather than analyst-driven, and represents direct company-level support for this market's double-digit growth rate.

Leading Manufacturers Are Actively Acquiring to Expand Busway Capabilities

Busway manufacturers such as named brands are actively marketing to centralize and streamline the portfolio of products. These are best suited for data center power distribution over 2024 and 2025. Schneider Electric released its I-Line Track Medium Power Distribution Busway in April 2024, an unconfined-track range of power distribution products specifically designed for the data center industry, and optimised for flexible tap-off configurations. Legrand also grew its North American manufacturing base through the acquisition of Power Bus Way. This is a Canadian company producing power bus systems and high-current power distribution in December 2024. Before Legrand made its latest acquisition, Linkk Busway Systems in Malaysia, which specializes in cable bus systems for data center grey space applications, in June 2025.

Key Insight: All three of these acquisitions center on data center applications instead of the manufacturer's wider industrial electrical business and comprise two acquisitions where the geographical component and the manufacturing of data center-specific equipment appear to be well in advance of any need.

Independent Market Research Broadly Corroborates the Regional Ranking, With Some Divergence in Magnitude

I believe the adjacent data center busbars market serves as a useful benchmark for exact comparison to the region's other data. North America will account for some 48% of the total, Europe some 27%, and Asia-Pacific roughly 25%, while Asia-Pacific is placed at the head of the fastest-growing region with a CAGR of 14.6% in the projected period. The overall rank order is agreed on by both, with North America placed at the top and the relatively close Europe and Asia-Pacific regions following, and both sources recognise Asia-Pacific as the fastest-growing region.

Key Insight: North America market size is significantly smaller than the independent estimate, and that of Asia-Pacific is significantly higher. Both estimates had the same conclusion as the clients', but the direction of the wind does seem to differ in the estimates. By how much these estimates differ does seem to depend on the methodology and exactly how the different market is defined.
