SoftBank (9984.T) stock analysis, November 4, 2025: SoftBank tests ¥26,510 support as OpenAI's complex financing clouds Vision Fund value

Published November 4, 2025 · updated 2025-12-29 · 9984.T chart, levels and live analysis

Key Updates

SoftBank Group is down 2.09% to ¥26,510 after two days of gains, consolidating at high levels. News about complex financial structures at OpenAI and a potential IPO create uncertainty around the valuation of a key Vision Fund asset, which may explain the current price pressure.

Current Trend

Despite the short-term pullback, SoftBank maintains a strong uptrend, up 258% over six months and 32.68% over the past month. Weekly performance remains positive (+4.08%), indicating resilience in the medium-term trend. The current dip looks like a natural consolidation after the prior session’s strong gains.

Investment Thesis

SoftBank’s appeal stems from its exposure to the AI revolution via the Vision Fund and direct stakes in industry leaders. The company is positioned as a key beneficiary of AI sector growth, holding sizable positions in OpenAI, Arm Holdings and other tech assets.

Thesis Status

The thesis remains intact but faces new risks. Reports on OpenAI’s complex financing raise questions about the true value of SoftBank’s investment in the firm. However, a potential OpenAI IPO could provide liquidity and clearer valuation, which would be positive for the Vision Fund portfolio.

Key Drivers

The primary driver continues to be AI sector development and the valuation of Vision Fund assets. News about OpenAI’s complex financial structures add uncertainty to the company’s real worth. At the same time, OpenAI IPO plans open the door to profit realization and greater valuation transparency.

Technical Picture

After reaching ¥27,075, the stock is pulling back toward ¥26,510, testing short-term support. Trading volume remains elevated, indicating continued investor interest. Key support sits around ¥25,000-¥25,500; a break could lead to a deeper correction toward ¥23,000.

Bull Case

  • Potential OpenAI IPO would add liquidity and could trigger a revaluation of SoftBank’s asset exposure (Axios)
  • Phenomenal 258% gain over six months shows strong investor interest in the company’s AI exposure
  • Positive monthly momentum (+32.68%) signals a durable uptrend

  • Weekly rise of 4.08% demonstrates the ability to bounce back quickly after short-term dips

Bear Case

  • Complex and circular financing structures at OpenAI raise doubts about the true value of SoftBank’s investment (NYT)
  • The current 2.09% pullback could signal the start of a larger decline after extreme gains
  • High volatility and reliance on private-asset valuations create risk of sharp re-ratings
  • Concentration in AI makes the company vulnerable to any negative sector news
  • Extreme growth levels (+258% over six months) may point to a speculative bubble forming
