SoftBank Shares Drop 13 Percent on AI Safety Concerns

SoftBank Group Corp. shares dropped more than 13% in Tokyo on Monday, marking the steepest intraday decline since late June. The sell-off was triggered by calls from the heads of OpenAI and Anthropic for developers to slow the pace of artificial intelligence development to address safety risks. This move heightened market anxiety regarding the Japanese tech investor’s aggressive financial strategy to fund its expanding AI portfolio.

The company is one of the largest backers of OpenAI, with its total investment in the ChatGPT developer expected to reach nearly $65 billion by October. Credit default swaps for SoftBank widened to their highest level since March 30, approaching three-year highs. Investors are increasingly concerned about founder Masayoshi Son’s commitment to multibillion-dollar AI projects with uncertain revenue timelines, a stance he has defended by dismissing bubble concerns as ignorant.

Debt Load Fuels Market Anxiety

SoftBank has significantly increased its debt levels to finance its AI ambitions. Last week, the company secured an $11.87 billion loan to bolster its investment in OpenAI, according to Bloomberg News. This follows a ¥1 trillion retail bond issue, a $10 billion loan linked to OpenAI shares, and potential bond sales of up to $20 billion.

These financing moves support acquisitions such as ABB Robotics and DigitalBridge, as well as plans to build data centers globally. The company is also accelerating the repayment of short-term obligations, paying down the $25.9 billion balance on a $40 billion debt facility obtained earlier this year before its March maturity. This rapid debt restructuring underscores the financial pressure associated with maintaining its leading position in the AI sector.

Delayed IPO Impacts Monetization Timeline

OpenAI co-founder Sam Altman confirmed that the startup will not list in 2026, a decision that directly affects SoftBank’s ability to monetize its 13% stake. This delay defers potential liquidity events and increases the risk of further capital commitments from SoftBank. The company had to provide guarantees to secure a $10 billion margin loan for its Vision Fund 2, highlighting the interconnected financial risks.

Despite Anthropic chief Dario Amodei’s assurance that slowing frontier development will not reduce spending, market sentiment remains cautious. SoftBank shares are down approximately 30% from their June peak, reflecting broader concerns about competition, rising sector debt, and recent security breaches. The uncertainty surrounding the pace of AI advancement continues to weigh on investor confidence in the company’s long-term valuation.

Quarterly Earnings Show Mixed Signals

In the June quarter, SoftBank reported a profit supported by significant gains from its stakes in Intel Corp. and ByteDance Ltd. However, these results do not fully offset the market’s apprehension regarding the sustainability of its AI investments. The company’s financial performance remains heavily tied to the valuation of its private AI holdings, which are subject to volatile market conditions and regulatory scrutiny.

As the industry grapples with safety protocols and funding structures, SoftBank faces the challenge of balancing aggressive growth with financial stability. The recent share decline serves as a reminder of the high-risk nature of its strategy, with investors closely monitoring any further developments in OpenAI’s roadmap and SoftBank’s debt management practices.
