The brief

SoftBank Group’s market value has fallen by half from its peak, as investor concerns about AI spending and financing weigh on the company’s valuation. The Japan Times reported that SoftBank shares fell 6.9% on Thursday, leaving them 50% below the all-time high reached on June 2. Its market capitalization stood at about ¥24.7 trillion ($157 billion).

The Japan Times said the valuation had dropped below Hitachi and Recruit after SoftBank briefly surpassed Toyota. Its account linked the weaker valuation to higher borrowing costs and concerns about the sustainability of SoftBank’s AI investments. These are reported investor concerns, not a company statement about the reasons for the share-price movement.

Gotrade News separately reported that SoftBank shares fell 6.0% to ¥4,554 on Tuesday. The outlet said the company’s five-year credit-default swaps climbed to 432 basis points, their highest level in nearly four years. The Japan Times also placed SoftBank’s credit-default swaps at a nearly four-year high on Tuesday, without giving a basis-point figure in its key facts.

The financing concern extends beyond SoftBank in the Japan Times account. It reported that CoreWeave bond prices fell to levels associated with distress, raising concern about financing risks across the AI industry. The outlet did not give bond prices or describe a specific financing event at CoreWeave.

Kazuyuki Muramatsu of Nagomi Capital said SoftBank’s leveraged finances and rising borrowing costs leave the company exposed to scrutiny of AI-related companies. That assessment connects the company’s financing profile to investor attention, while the reported market-value decline and credit-default-swap levels provide the financial measures described in the coverage.

Gotrade News also reported the debut of South Korean AI infrastructure firm Elice: its shares fell 28% on Tuesday, October 20, according to Investing.com, despite strong demand for its 201.1 billion won IPO before trading began.

The same outlet said Australia’s Nvidia-backed Firmus shelved a planned $5 billion IPO the previous week amid growing scrutiny of AI valuations, citing Investing.com. Those examples provide adjacent evidence of concern around AI company valuations, but do not establish that either event caused SoftBank’s share decline.

The Japan Times account places SoftBank’s market-value fall alongside AI investment concerns, borrowing costs and financing risk elsewhere in the sector. Gotrade News supplies Tuesday trading and credit-default-swap figures, as well as the Elice and Firmus examples. SoftBank’s next scheduled quarterly earnings report is November 10, according to Gotrade News.

Why it matters

  • SoftBank shareholders face a sharp valuation decline: the company’s market value is about ¥24.7 trillion, 50% below its all-time peak.
  • SoftBank’s borrowing-cost exposure is visible in the reported credit-default swaps: Gotrade News put its five-year swaps at 432 basis points on Tuesday, while the Japan Times described them as near a four-year high.
  • Investors in AI-related companies face signs of financing strain beyond SoftBank: the Japan Times said CoreWeave bonds fell to levels associated with distress.
  • AI businesses seeking public-market financing face valuation scrutiny in the examples reported by Gotrade News: Elice shares fell 28% on debut despite heavy IPO demand, and Firmus shelved a planned $5 billion IPO.

What to watch next

  • Whether SoftBank Group’s quarterly earnings report, scheduled for November 10 according to Gotrade News, provides further information about the company’s finances and AI investments.
  • Whether SoftBank’s shares and credit-default swaps move further from the reported Tuesday levels of ¥4,554 and 432 basis points.
  • Whether CoreWeave bond prices move away from the levels the Japan Times associated with distress.
  • Whether Elice’s shares recover after their reported 28% debut decline.
