Published October 29, 2025 · updated 2025-12-29 · 9984.T chart, levels and live analysis

Key Updates

SoftBank Group continues its strong rise, gaining 3.85% to ¥27,135 since the last report. Foxconn’s announcement to invest up to $1.4 billion in AI infrastructure supports the upbeat sentiment around the AI ecosystem, in which SoftBank is actively investing through the Vision Fund. The company shows exceptional momentum with a 278.45% increase over the past six months, cementing its role as a key beneficiary of the AI revolution.

Current Trend

SoftBank is in a steady uptrend with exponential acceleration over the past six months. Gains of 42.52% over the month and 14.49% over the week indicate strong momentum. The current level of ¥27,135 sets new all-time highs, and the stock is consistently breaking technical resistance without major pullbacks.

Investment Thesis

The thesis for SoftBank is built on its position as a leading global investor in AI and tech startups via the Vision Fund. The company benefits from the AI boom, holding stakes in key AI firms and emerging startups. A diversified portfolio of tech assets provides exposure to the fastest-growing segments of the global economy.

Thesis Status

The investment thesis is fully validated by the recent performance. A 278.45% rise over six months demonstrates the correctness of the AI-focused strategy. Foxconn’s large AI-infrastructure investment confirms sustained demand for AI solutions, which is favorable for SoftBank’s portfolio companies.

Key Drivers

The primary driver remains the global AI boom and corporate spending on AI technologies. Foxconn’s announcement of a $1.4 billion AI equipment investment illustrates the scale of corporate demand for AI infrastructure, creating a supportive environment for Vision Fund portfolio companies. Ongoing valuation growth of tech firms underpins SoftBank’s asset values.

Technical Picture

Technically, SoftBank shows a classic parabolic rise with successive new highs. The ¥27,135 level faces no immediate technical resistance, opening room for further upside. Trading volumes remain elevated, confirming the trend’s durability. The nearest support lies around ¥25,000–¥26,000.

Bull Case

  • Corporate AI-infrastructure spending continues to climb, as shown by the Foxconn $1.4 billion investment announcement, supporting valuations of AI companies in SoftBank’s portfolio
  • Exponential 278.45% growth over six months signals structural shifts in AI asset valuations and the tech sector
  • Lack of major corrections during the parabolic run suggests strong institutional demand
  • A diversified Vision Fund portfolio provides exposure to multiple AI trends and tech innovations
  • Global digital transformation and AI adoption create long-term structural demand for technology solutions

Bear Case

  • The parabolic 278.45% rise over six months raises the risk of a technical correction on any negative catalyst
  • High concentration in the AI sector makes SoftBank vulnerable to sector shocks or shifts in investment sentiment
  • Absence of fresh fundamental catalysts in the news flow could trigger profit-taking
  • Extreme tech valuations may be trimmed if monetary policy tightens
  • Reliance on private-market volatility and IPO activity creates overvaluation risk for portfolio assets
