Meta Plans 7,000-Kilometer Subsea Cable Between US and France
Meta's building infrastructure, not models. A 7,000km subsea cable between US and France signals where the real AI bottleneck lives: moving data, not making it.
Why it matters
Meta is investing in the physical layer of AI — submarine cables and data-center connectivity — to handle the compute and model-serving demands of its agentic and multimodal roadmap. This is part of the broader buildout story: the infrastructure race is as critical as the silicon race.
