SoftBank Shares Plunge 10% on OpenAI Loan Hurdles and AI Valuation Fears

Key Facts

Amid mounting concerns over AI sector valuations, Asian technology stocks experienced a broad sell-off. SoftBank shares plunged 10% following reports that the company faced difficulties securing a $6 billion margin loan backed by its stake in OpenAI. Asian semiconductor and tech equities resumed their decline, tracking Wall Street weakness as investors questioned whether AI-related gains have outpaced fundamental growth.

This downturn occurs as market participants closely monitor major sector peers; for instance, Nvidia has recently seen heightened volatility reflecting general caution regarding the sustainability of the AI rally (per market data). Peers such as TSMC and ASML have also faced selling pressure in recent sessions as investors re-evaluate capital flows into the chip sector, compounding the negative sentiment surrounding highly leveraged firms like SoftBank.

At the close on June 10, 2026, SoftBank (9984.T) stood at 6332 JPY, hitting its daily low during a volatile session. Investors are now looking ahead to upcoming Japanese economic catalysts, including household spending data, and any official updates from SoftBank management regarding its future debt structuring and financing strategy.
