SoftBank's Robot Bet Comes Into Focus as Starlink Goes Global and the Stock Catches Its Breath
Published on 09/10/2026 at 22:40 | Editorial boerse-global.de
SoftBank Group is assembling something bigger than a portfolio of investments, and the pieces are moving into place on several fronts at once. While the market fixates on the financing machinery behind its OpenAI stake, the Japanese conglomerate is simultaneously negotiating a multi-billion-dollar robotics acquisition, rolling out satellite connectivity across three continents, and testing generative AI at municipal service counters.
A $6 Billion Move Into Humanoid Robotics
Reuters reported on August 26 that SoftBank is in talks to take a majority stake in 1X Technologies, a humanoid robotics developer with close ties to OpenAI, at a valuation of roughly $6 billion. The deal would extend SoftBank's reach beyond funding AI models into the physical applications those models ultimately power.
Set that alongside the company's other moving parts and a pattern emerges. SoftBank will retire the outstanding $25.9 billion from its OpenAI bridge financing on September 15, is raising between $10 billion and $20 billion in fresh debt through a New York roadshow, and is negotiating a billion-dollar-plus acquisition in robotics — all in the same window.
Add to that the IPO filing of SB Energy, a SoftBank-affiliated business linked to the Stargate initiative, which posted a 66.4 percent year-on-year revenue increase in the first half of 2026. Taken together, these are not isolated transactions but a tightly choreographed wager on the entire AI stack, from language models and energy supply through to physical robots.
Starlink Service Crosses Borders
The operational side is advancing just as quickly. "SoftBank Starlink Direct" launches internationally on September 28, with users in the United States connecting through T-Mobile USA, in Canada via Rogers, and in New Zealand through One NZ. A Philippine rollout with partner Globe Telecom is slated for the autumn.
Should investors sell immediately? Or is it worth buying SoftBank Group?
Customers on SoftBank, Y!mobile Simple, or LINEMO Best Plan tariffs get access at no extra charge; other plans can add the option for 1,650 yen per month. Initially the service covers SMS, MMS, RCS, and in-app data only — voice calls are excluded. An iPhone 13 or newer running iOS 27.0 or higher is required.
The international expansion signals that SoftBank is scaling its satellite connectivity business well beyond its home market, giving investors a second front where the group builds reach in traditional telecommunications even as it pours billions into AI.
Generative AI at the Municipal Counter
Since June, SoftBank has been piloting a search system for government employees in the city of Fujieda, Shizuoka Prefecture. The setup pairs SB Intuitions' in-house generative AI "Sarashina" with the "dailyAI" system.
The trial runs under the guidance of Japan's Ministry of Internal Affairs and Communications, with NRI overseeing the project and Gravis Architects as partner. Three departments are involved: the citizen services desk, regional nursing care, and social policy. Data is processed through the Type A cloud platform, with all information kept within Japan.
Such projects underscore the group's strategy of not merely financing its own AI technology but deploying it in the public sector — a field that could open new revenue streams over the long term, independent of investment gains.
Momentum Meets Valuation
The share price tells its own story about how much of this has already been priced in. After a blistering run — 28 percent over seven days and 25 percent across 30 days — the stock took a breather, slipping from EUR 37.58 the previous day to EUR 36.52, a decline of 2.8 percent. On a 30-day view the gain still stands at 29 percent, with a market capitalization equivalent to EUR 198.28 billion.
SoftBank Group at a turning point? This analysis reveals what investors need to know now.
With annualized 30-day volatility at 64 percent, the pullback is hardly surprising. An RSI of 68.2 — and 72.6 in the secondary reading — points to technically overheated conditions, making a pause after such a sprint look like a normal part of the cycle rather than a warning sign.
Reuters noted in early September that the planned SB Energy listing may be premature, flagging risks from the intertwined relationships between SoftBank and its subsidiary. That criticism has merit, though it addresses a peripheral matter while the core of the strategy remains direct participation in AI value chains. The 1X talks fit that picture precisely: SoftBank wants to be more than OpenAI's financier — it wants to control physical use cases through robotics.
The debt burden is visibly growing. Retiring the $25.9 billion line on September 15, the previously placed retail bond carrying a 4.75 percent coupon on 1 trillion yen, and the dollar-denominated junk bond now being marketed all show how much external capital SoftBank is marshaling to fund its AI ambitions. That leverage is a means to an end, not an end in itself.
The flip side deserves mention: should the New York roadshow come in weaker than hoped, or the robotics wager prove overpriced, the stock's elevated volatility would magnify any disappointment brutally. For now, the operational progress on Starlink and the government AI pilot offer positive headlines away from the debt debate, even if they are unlikely to shift investors' overall risk assessment given the stretched valuation. What matters most is whether the group can complete its financing plans around the OpenAI investment without friction.
