The chain that matters

Volex is the company he runs in 2026.

Volex makes copper interconnect cables. These are short, thick copper cables that plug GPUs into other GPUs inside data centres.

They are called DAC, ACC and AEC cables. Speeds: 400G, 800G and 1.6T.

The data centres that buy them are the ones that train AI models. Volex calls these customers “hyperscale, cloud and AI-driven infrastructure”. Source: Volex Data Centres page.

Volex’s FY2025 results: data-centre revenue grew +33% year-on-year. Data centres are 48.3% of the Complex Industrial Technology segment. Source: Volex FY2025 prelim (PDF).

The Rothschild family financed and refined copper for over 150 years.

Rio Tinto — founded 1873 with Rothschild-arranged financing.

Société Le Nickel — from 1880.

Royal Mint Refinery in London — lease acquired by N M Rothschild & Sons in 1852. Archive reference RAL 000/2056. Source: Rothschild Archive — Royal Mint Refinery.

So the line is: family financed copper mining and refining → 2026 family vehicle sells copper cables that wire up the AI data centres.
