Prysmian signs up to €5.5 billion Molex deal for optical cables inside data centers

Prysmian said on 20 July it signed an up to €5.5 billion, ten-year deal with Molex for optical cables inside data centers and will expand US fiber capacity.

On 20 July 2026 Prysmian said it signed an agreement with Molex worth up to €5.5 billion over up to ten years, including a €550 million upfront payment, to supply optical cables for use inside data centers. It said the deal is part of a wider set of agreements with hyperscalers and data center infrastructure providers expected to add over €10 billion of cumulative value up to 2035, and that it will spend €1.25 billion up to 2031 to more than double its US fiber capacity. Prysmian's chief executive said the fiber and cables are needed to sustain the huge funding that AI-driven infrastructure will need. We file this because Prysmian ties the deal to AI-driven data center demand in its own words. How we read it: AI data center builders are locking in cable supply years ahead. What would change this: slower data center building. Why it matters to you: it shows AI demand reaching basic supply chains.

What this doesn't prove

Company press release only. The €5.5 billion is a ceiling over up to ten years and the €10 billion is a company projection. The hyperscalers are not named.
