YTD as of 2026-07-10 · source: Yahoo Finance
SoftBank's thesis is 'a leveraged AI net-asset-value (NAV) play.' The holding company's value hinges effectively on Arm (~90% controlling stake) and OpenAI (~13%, ~$64.6B committed), and even the record FY2025 net income of JPY 5.0tn is largely a paper gain from marking OpenAI. On top of that it serves as financial lead of the $500B Stargate project, scaling a directional bet on AI infrastructure. The catch is how it funds this — it invests via large borrowings (an ~$11.5B Arm-share margin loan, an ~$8.5B OpenAI bridge loan), so if Arm or OpenAI valuations wobble, NAV and borrowing capacity are squeezed together. The steady cash flow of telecom subsidiary SBKK is the cushion, and the stock trades between its NAV discount and AI sentiment.
