SoftBank Group stock swings to 1.12 trillion yen quarterly loss

SoftBank Group reported a fiscal second-quarter net loss on Tuesday, November 10, 2026, as investment losses, financing costs and spending tied to US AI infrastructure weighed on the technology investor. CNBC reported that the loss reached 1.12 trillion yen in the quarter, reversing a profit of 2.5 trillion yen a year earlier.

SoftBank also recorded a 597.2 billion yen loss during the six months ended September 30 after it changed procurement plans for power-generation equipment supporting AI data center projects in the United States. The charge highlights the execution and funding risks attached to the group's effort to expand its AI infrastructure exposure.

Portfolio gains lose momentum

The Vision Fund segment swung to a loss of 81.58 billion yen in the quarter, compared with a profit of 2.38 trillion yen in the year-earlier period. Investment gains at the Vision Funds fell to 85.45 billion yen from 2.81 trillion yen, while declines in publicly traded holdings including Coupang and Grab hurt the portfolio.

SoftBank said revenue rose 13.3% in the six months ended September 30, supported by telecommunications and AI computing businesses. The result shows that operating growth continues, but the group's reported earnings remain highly sensitive to valuation changes across its technology holdings.

At the end of September, SoftBank's cumulative investment in OpenAI stood at 54.6 billion dollars. The company put the fair value of that stake at 99.6 billion dollars and the cumulative investment gain at 45 billion dollars, leaving the position central to the investment case and to scrutiny of future AI returns.

SoftBank Group stock traded at 20.85 euros on Lang & Schwarz at 09:41 CET on Tuesday, November 10.
