32% confidenceSon has held talks about a much larger AI data center commitment in France than SoftBank's already-disclosed ~$87 billion plan, floating a figure as high as $100 billion, though people familiar with his thinking say he may prioritize other projects and commit less.
Reported by people familiar with the matter; the $100 billion figure is Son's floated upper bound rather than a confirmed commitment, distinct from SoftBank's already-announced and better-sourced ~$87 billion France plan.
