Key Takeaways
- SoftBank shares plunged 12% in Tokyo following news that OpenAI might postpone its public offering until 2027
- The Japanese conglomerate’s aggregate exposure to OpenAI is projected to reach approximately $65 billion by October
- A postponed OpenAI listing could perpetuate the valuation discount that has historically affected SoftBank’s share price
- SoftBank is servicing a $40 billion bridge financing facility linked to its OpenAI position, with a March 2027 maturity date
- Investment banks Goldman Sachs and Morgan Stanley are working with OpenAI on listing preparations, with autumn 2026 remaining a possibility
Shares of SoftBank Group experienced a sharp 12% decline during Friday’s Tokyo session — marking the steepest intraday loss in over three months — following a New York Times report suggesting OpenAI could defer its initial public offering until 2027.
Advisors working with OpenAI have reportedly expressed concerns that current volatility in technology equities could undermine appetite for a listing targeting a $1 trillion enterprise value. This single piece of news was sufficient to erase a substantial portion of the gains SoftBank had accumulated during the recent OpenAI-driven rally.
SoftBank’s aggregate commitment to OpenAI is anticipated to approach roughly $65 billion by October. At the conclusion of last year, the fair market value of this position stood at $79.6 billion, compared to a cumulative investment cost of $34.6 billion.
The anticipation of a lucrative OpenAI exit had propelled SoftBank to record valuation levels, with its market capitalization briefly surpassing that of Toyota last month. Friday’s sharp reversal abruptly halted that upward trajectory.
Hiroki Takei, a market strategist at Resona Holdings, outlined why a public listing carries such significance for SoftBank’s market valuation. The conglomerate maintains positions in hundreds of privately-held enterprises that lack transparent market pricing, creating substantial challenges for investors attempting to assess portfolio value.
A publicly-traded OpenAI would establish a transparent market reference point for one of SoftBank’s most substantial holdings and could potentially narrow the conglomerate discount that has persistently pressured the stock. “Reports of a listing postponement understandably dampen those prospects,” Takei noted.
Financial Implications and Complexities
SoftBank’s financial situation regarding this investment presents significant complexity. The firm secured a $40 billion bridge financing facility to support its OpenAI commitments, with repayment obligations coming due in March 2027. Recent efforts to refinance approximately $6 billion of this debt through a margin loan secured by its OpenAI holdings encountered obstacles earlier this month, as lenders struggled to establish appropriate pricing for an illiquid private asset.
Absent a public market listing, these refinancing challenges are unlikely to diminish.
The company’s Vision Fund division reported approximately $46 billion in investment appreciation during the twelve-month period ending March 31. The overwhelming majority of these gains originated from the increasing valuation assigned to its OpenAI portfolio.
This concentration creates significant exposure in both directions — and Friday’s market response demonstrated that investors clearly recognize this risk.
Public Offering Could Still Materialize in 2026
OpenAI has previously submitted confidential registration materials to the US Securities and Exchange Commission. Goldman Sachs and Morgan Stanley are serving as advisors on a potential public offering that could potentially occur as soon as fall 2026.
The company led by Sam Altman is navigating the technical requirements of transitioning to public markets. Whether market conditions will prove favorable remains an open question.
Friday’s selloff in SoftBank shares coincided with broader weakness across Asian and European technology stocks. Market participants were simultaneously processing Apple’s disclosure of price adjustments on certain MacBook and iPad models, contributing to a cautious sentiment throughout the sector.
SoftBank’s 12% Friday decline positioned the stock for one of its most severe single-session losses this year.
