SoftBank (9984.T)

Key Updates

SoftBank shares declined 6.26% to ¥5,747 on May 11, marking a continuation of the correction phase following the May 7 daily limit surge. The pullback extends the retracement from ¥6,424 to approximately 10.5% over four trading sessions, representing a technical consolidation after the extraordinary 18% single-day gain. Despite the near-term weakness, the stock maintains a robust YTD performance of +30.61% and a remarkable 1-month gain of +52.12%, supported by the $100 billion Roze data center IPO announcement on April 30. The correction appears technical in nature, with no negative fundamental developments reported, as the company advances its AI infrastructure monetization strategy through the planned spin-off.

Current Trend

SoftBank exhibits a strong uptrend on medium-term timeframes despite recent volatility. The YTD gain of +30.61% and 6-month performance of +1.29% demonstrate sustained momentum, while the extraordinary 1-month surge of +52.12% reflects accelerating investor enthusiasm for AI exposure. The stock established a recent peak at ¥6,424 on May 7, representing a critical resistance level. Current price action suggests consolidation between ¥5,700-¥6,100, with the recent low around ¥5,747 potentially forming near-term support. The 5-day performance of +9.09% indicates underlying strength persists despite the daily decline, suggesting buyers remain active on pullbacks. Trading volume patterns following the May 7 surge indicate profit-taking rather than fundamental deterioration.

Investment Thesis

SoftBank's investment thesis centers on its position as the premier public market proxy for AI infrastructure and OpenAI exposure, enhanced by strategic asset monetization through high-value spin-offs. The company holds approximately 90% of Arm Holdings, which has surged 60% monthly, and maintains over $64 billion in OpenAI investments as the largest shareholder. The newly announced Roze data center venture targeting a $100 billion valuation represents a transformative monetization opportunity, leveraging SoftBank's robotics capabilities (from the $5.4 billion ABB acquisition) and existing infrastructure assets including SB Energy. This spin-off strategy addresses previous balance sheet concerns while unlocking significant embedded value. The thesis assumes continued AI infrastructure demand growth, successful execution of the Roze IPO by year-end 2026, and maintenance of the improved loan-to-value ratio estimated at 11% following recent stock appreciation.

Thesis Status

The investment thesis remains intact and has strengthened materially since the previous report. The Roze data center announcement validates the asset monetization strategy, providing a concrete path to unlock $100 billion in value while addressing leverage concerns. The company's loan-to-value ratio improvement to approximately 11% demonstrates successful balance sheet management despite the $30 billion OpenAI commitment. However, execution risks have increased, as some executives reportedly view the year-end IPO timeline and $100 billion valuation as "too ambitious." The recent 10.5% correction from peak levels represents healthy consolidation rather than thesis deterioration, with fundamental catalysts remaining firmly in place. The combination of Arm's continued strength, OpenAI's expanding user base (Codex reaching 4 million weekly active users), and easing geopolitical tensions supports the core AI infrastructure growth narrative.

Key Drivers

The primary near-term catalyst is the Roze data center spin-off, targeting a $100 billion valuation and year-end IPO on a US exchange. This venture will construct AI-optimized data centers using robotics and incorporate existing assets from SB Energy, which has completed projects for OpenAI and Google Cloud. Secondary drivers include Arm Holdings' sustained momentum, with the subsidiary reporting strong fiscal Q4 profits and robust chip demand, contributing to SoftBank's 90% ownership stake appreciation. Geopolitical developments remain supportive, as easing US-Iran tensions have reduced energy costs and supply chain disruption risks for semiconductor manufacturing. OpenAI's operational progress, including Codex user growth from 3 million to 4 million weekly actives within two weeks, reinforces confidence in SoftBank's largest investment. The successful $3.56 billion bond raise in April provides liquidity to refinance existing debt and partially repay the OpenAI bridge loan, improving financial flexibility.

Technical Analysis

SoftBank is undergoing a technical correction within a broader uptrend. The stock surged to ¥6,424 on May 7, hitting the daily limit with an 18% gain, establishing a clear resistance level. Since then, the price has retraced 10.5% to ¥5,747, forming a consolidation pattern. Key support appears around ¥5,700-¥5,750, representing the current price zone, while resistance sits at ¥6,100 (recent trading range high) and ¥6,424 (absolute peak). The 5-day performance of +9.09% indicates the correction is shallow relative to the recent rally, suggesting strong underlying demand. Volume patterns show profit-taking rather than distribution, with the stock maintaining well above the 1-month starting point despite daily volatility. The YTD gain of +30.61% positions the stock in a sustained uptrend, with the recent pullback representing approximately 25% retracement of the April-May rally. A break above ¥6,100 would signal resumption of the uptrend, while a move below ¥5,500 would indicate deeper consolidation.

Bear Case

• Roze IPO Execution Risk and Valuation Concerns: Internal executives reportedly view the year-end timeline and $100 billion valuation target as "too ambitious and subject to change," creating uncertainty around the primary value catalyst and potential for disappointment if the spin-off is delayed or repriced.

• High Valuation Following Rapid Appreciation: The 52.12% one-month gain and 30.61% YTD performance have compressed potential upside, with the stock trading near previous peak levels that preceded a nearly 50% decline, suggesting limited margin of safety at current valuations absent further fundamental catalysts.
