SoftBank (9984.T)

Key Updates

SoftBank shares surged 10.92% to ¥4,715 on February 10, 2026, driven by exceptional operational performance from its telecom subsidiary and strengthening AI narrative through Arm Holdings. The telecom unit reported record nine-month revenue of ¥5.2 trillion (up 8% YoY) and raised full-year guidance significantly, with operating income targets increased to ¥1.02 trillion. This marks a decisive shift from the previous correction, with the stock now up 7.16% YTD and 36.03% over six months, validating the AI investment thesis despite ongoing concerns about leverage and capital allocation.

Current Trend

SoftBank has entered a strong upward trajectory with consecutive positive sessions: +10.92% today, +9.65% over 5 days, and +10.60% over one month. The YTD performance of +7.16% represents a complete recovery from the mid-January correction that had pushed the stock to -13.43% YTD. The 36.03% six-month gain demonstrates sustained momentum driven by AI positioning. The stock has established new support at the ¥4,250 level and is testing resistance near ¥4,715, with technical indicators suggesting continuation of the uptrend as operational fundamentals strengthen alongside strategic AI investments.

Investment Thesis

The investment thesis centers on SoftBank's transformation into a dominant AI infrastructure player through strategic stakes in OpenAI (11% ownership with potential $30 billion additional investment), Arm Holdings' semiconductor positioning, and the $500 billion Stargate initiative. The core value proposition combines: (1) exposure to OpenAI's potential $830 billion valuation, where SoftBank's stake appreciated $14.6 billion as of November 2025; (2) stable cash generation from the telecom business now delivering ¥1.02 trillion operating income; (3) strategic AI infrastructure assets including DigitalBridge ($3 billion acquisition) and Ampere Computing ($6.5 billion). The thesis assumes OpenAI monetization through potential IPO and sustained AI infrastructure demand offsetting elevated leverage concerns.

Thesis Status

The thesis is strengthening materially. Today's surge validates the dual-pillar strategy: the telecom unit's raised guidance provides critical cash flow stability (¥6.95 trillion revenue, ¥1.02 trillion operating income) while the AI narrative gains credibility through Arm's positioning and OpenAI discussions. The telecom business demonstrates strategic discipline, sacrificing 100,000 smartphone subscribers for improved profitability (3% revenue growth, 6% segment income growth). However, leverage remains the primary risk—Bloomberg Intelligence notes the potential $30 billion OpenAI investment could push loan-to-value ratio to the 35% downgrade trigger, while S&P Global warns about creditworthiness pressure from asset liquidations (entire Nvidia and T-Mobile stakes sold). The abandoned $50 billion Switch acquisition suggests management is calibrating capital deployment more carefully, partially addressing previous concerns about aggressive expansion.

Key Drivers

The primary catalyst is SoftBank Corp's exceptional Q3 performance, with record nine-month revenue of ¥5.2 trillion and raised full-year guidance to ¥6.95 trillion revenue and ¥1.02 trillion operating income. The strategic shift toward profitability over subscriber growth—accepting 100,000 subscriber losses while achieving 6% segment income growth—demonstrates operational maturity. The AI narrative strengthened through potential $30 billion additional OpenAI investment, which would increase SoftBank's stake beyond 11% in a company valued at $830 billion. Arm Holdings' positioning in AI semiconductors provides additional validation. Counterbalancing factors include the abandoned $50 billion Switch acquisition, suggesting capital constraints, and Bloomberg Intelligence warnings about leverage approaching downgrade triggers at 35% loan-to-value ratio.

Technical Analysis

SoftBank has broken through resistance at ¥4,250 with strong momentum, establishing ¥4,715 as the new technical level to watch. The 10.92% single-day surge on high volume indicates institutional accumulation following the telecom earnings beat. The stock has formed a clear recovery pattern from the January lows, with the 5-day (+9.65%), 1-month (+10.60%), and 6-month (+36.03%) trends all aligned positively. The YTD performance of +7.16% demonstrates resilience after the mid-January correction to -13.43%. Support levels are now established at ¥4,250 (previous resistance), ¥3,978 (February 6 level), and ¥3,809 (February 5 level). The RSI likely indicates overbought conditions short-term, but the fundamental catalyst strength suggests consolidation rather than reversal. Volume patterns confirm renewed institutional interest in the AI transformation story.

Bull Case

• OpenAI stake appreciation and IPO potential: SoftBank's 11% OpenAI stake increased in value by $14.6 billion as of November 2025, with the company valued at $830 billion in potential fundraising. An IPO would crystallize substantial gains and validate the AI investment thesis. Source
• Telecom business exceeding expectations with raised guidance: SoftBank Corp reported record nine-month revenue of ¥5.2 trillion (up 8% YoY) and raised full-year targets to ¥6.95 trillion revenue and ¥1.02 trillion operating income, demonstrating stable cash generation to fund AI investments. Source
• Strategic AI infrastructure positioning through multiple assets: SoftBank has assembled a comprehensive AI portfolio including OpenAI (11%+ stake), Arm Holdings (semiconductor exposure), DigitalBridge ($3 billion), Ampere Computing ($6.5 billion), and participation in the $500 billion Stargate initiative. Source
• Profitability-focused operational discipline: The telecom unit achieved 3% revenue growth and 6% segment income growth despite losing 100,000 smartphone subscribers, reflecting strategic prioritization of margins over market share that improves long-term cash flow quality. Source
• Potential for additional OpenAI investment at attractive terms: Discussions for up to $30 billion additional investment in OpenAI's $100 billion funding round could increase SoftBank's ownership in what CEO Masayoshi Son views as an "all-in" AI bet with transformative potential. Source

Bear Case

• Leverage approaching critical downgrade triggers: Bloomberg Intelligence warns that a $30 billion additional OpenAI investment could push SoftBank's loan-to-value ratio to the 35% downgrade trigger, potentially affecting credit ratings and financing costs at a critical expansion phase. Source
• Forced asset liquidations indicating capital constraints: SoftBank has liquidated its entire Nvidia and T-Mobile stakes to fund AI investments, with S&P Global Ratings warning that the AI spending spree and declining Arm share values are pressuring creditworthiness. Source
• Abandoned Switch acquisition signals capital allocation challenges: The termination of the planned $50 billion Switch data center acquisition, despite its strategic fit with the Stargate initiative, suggests SoftBank faces constraints in executing its AI infrastructure strategy. Source
• OpenAI investment concentration risk: With an existing 11% stake and potential $30 billion additional investment, SoftBank is heavily concentrated in a single private AI company valued at $830 billion, creating significant valuation and liquidity risk if AI monetization disappoints. Source
• Telecom subscriber losses indicating competitive pressure: The loss of 100,000 smartphone subscribers in Q3 due to tightened customer-acquisition policies, while strategically justified, demonstrates ongoing competitive challenges in the core Japanese telecom market. Source
