Overview

SoftBank Group is the Japanese investment conglomerate led by Masayoshi Son and the primary capital vehicle behind the Stargate AI data-center build-out template originally announced with OpenAI and Oracle. Through 2026 it has extended the Stargate playbook beyond the US — including a parallel ~$500B Ohio commitment and, as of May 30, an “up to €75B / 5 GW” pledge to French AI data centers at Choose France 2026.

Timeline

  • 2026-05-31-AI-Digest — Announces at Choose France 2026 on 2026-05-30 an “up to €75B (~$87B) to build 5 GW of AI data-center capacity across three French sites — Dunkirk/Loon-Plage, Bosquel, and Bouchain — in partnership with EDF on power and Schneider Electric on robotics build-out. The €45B Phase 1 delivering 3.1 GW in Hauts-de-France by 2031 is the firm-ish part; the remaining ~1.9 GW / ~€30B Phase 2 is effectively an option post-2031 rather than a closed commitment. Honest read: SoftBank extending its Stargate playbook to a European host country, not a centre-of-gravity shift — the parallel ~$500B Ohio commitment dwarfs the French number.
  • 2026-06-20-AI-Digest — SoftBank exercises the 2021 put option to exit its residual 9.65% Boston Dynamics stake, selling to Hyundai for $325M — implied ~$3.4B Boston Dynamics valuation, with the Hyundai board scheduled to approve on June 22. Mechanical follow-through on the 2021 majority-sale terms rather than a fresh strategic move; the put was negotiated as part of the original Hyundai-buy-majority deal four years ago. Reduces SoftBank’s physical-AI exposure at the marquee humanoid-robotics name even as the parallel French data-centre commitment and Stargate playbook remain the headline portfolio bets.
  • 2026-07-14-AI-Digest — Masayoshi Son calls nuclear fusion the most realistic long-term power source for AI data centres, projecting 3 terawatts of data-centre capacity by 2040 and framing natural gas as the near-term bridge (per Bloomberg). Lands alongside Bloomberg Opinion citing Goldman’s five-name (Alphabet, Amazon, Meta, Microsoft, Oracle) AI capex FY2025–2030 at ~$5.8T against a broader ~$7.6T industry-wide compute-plus-power-plus-data-centre estimate. Narrow read: attribute the 3TW-by-2040 figure and fusion framing explicitly to Son — he has been publicly fusion-bullish for years and BloombergNEF still flags fusion as facing technical and financial hurdles that keep it off named-hyperscaler PPA lines in H1 2026. Structural read the corpus carries: the $5.8T Goldman figure restates the scale the corpus has been carrying since 2026-07-12-AI-Digest‘s ~$350B five-year debt tally — same story from the equity-and-CapEx side rather than a new inflection. 90-day watch: whether any named hyperscaler signs a fusion PPA at line-item scale.
  • 2026-06-29-AI-Digest — Masayoshi Son dismissed orbital data centers at the June 23 SoftBank annual shareholder meeting, with TechCrunch’s June 27 follow-up amplifying the original remarks. Son’s argument is more specific than the “won’t reduce costs” headline summary: electricity is a small share of the data-center cost stack relative to chips, so the orbital solar-power efficiency case is structurally weaker than the pitch suggests, and the launch / maintenance / latency overhead offsets whatever electricity savings remain — plus the timing is wrong, with “the next few years” mattering more than where compute lands a decade out. The framing worth softening: this is not rare on-record skepticism about AI-infrastructure capex generally — Son is simultaneously the largest single backer of the OpenAI buildout and has signed off on $65B+ of terrestrial AI infra commitments through this cycle — it is specifically a bearish call on the space leg of the buildout from an investor doubling down on Earth-based capex. Sam Altman has voiced comparable doubt elsewhere; TechCrunch’s headline acknowledges Son “isn’t the only one.” The AI-infra capex thesis remains intact at the SoftBank level — what gets ruled out is the most speculative branch of the substrate map, not the substrate itself.

Key Developments

  1. €75B / 5 GW French AI Data-Center Pledge: The Choose France 2026 announcement is the largest single European AI-infrastructure commitment of 2026 in headline terms, but the load-bearing read is “announcement-grade, not signed-binding capex” — Phase 1 is firm-ish (€45B / 3.1 GW by 2031), Phase 2 is an option.
