AI Data Centers Set to Supercharge Southwire's Fortune

The Richards family, owners of Southwire, a leading U.S. electrical wire and cable manufacturer, is set to further expand its fortune thanks to the explosion in demand for electrical infrastructure driven by artificial intelligence (AI) data centers. With an estimated net worth of approximately $13.1 billion, the Richards family is recognized by Forbes as one of America's richest clans. The company achieved a record revenue of $9.7 billion in 2025, marking an increase of over 50% since 2021.

Founded in 1950 by Roy Richards Sr., Southwire, now 76 years old, manufactures roughly half of the wire and cable used to distribute electricity in the U.S. and its electrical wiring is found in about half of American homes. The rapid advancements in AI technology have led to a proliferation of next-generation data centers, powered by ultra-powerful GPU chips that demand 2 to 4 times more energy than traditional chips. This trend has placed unprecedented strain on electrical grids, making power availability the primary constraint for data center operators, even outranking GPU access.

In response to this massive surge in demand, Southwire has taken strategic steps. In November 2024, the company tripled the size of one of its plants in North Carolina, which produces heavy-duty cables essential for scaling AI data centers. Furthermore, Southwire has poured $1.8 billion into modernizing its facilities to better position itself for the AI-driven boom. According to David Long, CEO of the National Electrical Contractors Association, AI-driven data center energy demand is projected to rise by 175% by 2030. Southwire also demonstrated its commitment to energy efficiency solutions by making a strategic investment in Ndustrial, an AI-powered energy intensity platform, in January 2025.

This development provides a broader economic context not just for Southwire, but for the global energy infrastructure sector. Reports from the International Energy Agency (IEA) indicate that global data center electricity consumption is projected to more than double from approximately 415 terawatt hours (TWh) in 2024 to around 945 TWh by 2030, with AI identified as the primary driver of this growth. This comes at a time when electrical grids are struggling to keep pace with this rapid expansion, leading to numerous projects being stuck in grid connection queues. Even hyperscalers are bypassing public grids by investing directly in dedicated power sources.

Analysts and market expectations suggest that electrical infrastructure providers like Southwire will continue to play a critical role in the coming era. The company's investments in innovation and sustainability place it in an advantageous position within this new landscape. Southwire was recognized as a U.S. Best Managed Company for the seventh consecutive year in 2025, with advanced technology, including AI, taking a central role in driving efficiencies and enhancing product quality. This indicates that Southwire is not only poised to meet current demand but also to lead in developing innovative solutions for future energy needs.
