2025 marks Son’s AI resurgence, with SoftBank’s FY2025 revenue ~$44B (+7% YoY) and Q1 FY2026 ~$12.5B. His 29.68% stake (~$32B) and Arm (~90%, $130B+) tie to Huang’s Nvidia and Musk’s xAI (Stargate Project). Philanthropy via Masason Foundation (youth support) and solar investments (~$125M post-Fukushima) link to Gates/Bloomberg impact. Leverage (~1/3 shares pledged for $5.1B loans) amplifies volatility.
