SoftBank Group (ISIN JP3436100006) completed a USD 10.0 billion third and final investment tranche in OpenAI on October 1, 2026, while SoftBank Group stock gained 1.00 percent at Lang & Schwarz. According to SoftBank Group, the transaction completed the previously announced USD 30.0 billion follow-on investment program.

OpenAI commitment reaches USD 64.6 billion

The October 1 transaction lifted SoftBank Group's cumulative investment in OpenAI to USD 64.6 billion. The company said the tranche was funded with proceeds from senior notes issued in September, linking the investment directly to the group's financing strategy.

The same release said SoftBank Group canceled the remaining USD 10.0 billion of undrawn bridge-facility capacity effective September 30, 2026. All borrowings under that facility had been repaid, leaving the group with a completed investment program and a more clearly disclosed funding structure.

Revenue grows as profit declines

For the quarter ended June 30, 2026, SoftBank Group reported revenue of JPY 2.0 trillion, up 10.90 percent year over year, according to Bondsupermart. Gross profit rose 10.40 percent to JPY 1.1 trillion, showing that the operating businesses expanded alongside the investment portfolio.

The earnings mix was less straightforward. Net income attributable to shareholders fell 17.70 percent year over year to JPY 347.3 billion, even as investment gains surged to JPY 1.86 trillion from JPY 0.5 trillion in the year-earlier quarter, according to Bondsupermart. That contrast makes portfolio valuations, rather than revenue alone, central to the investment case.

Stock trades near the middle of its range

SoftBank Group stock was trading at EUR 35.49 at Lang & Schwarz on October 7, 2026 at 9:21 a.m. CEST, up 1.00 percent versus the prior close of EUR 35.14. The Tokyo Stock Exchange listing stood at JPY 6,310 on October 7, 2026, while its 52-week range was JPY 3,365.00 to JPY 9,074.00.

The next scheduled earnings release is November 10, 2026, when SoftBank Group is set to report results for the six-month period ended September 30, 2026, according to SoftBank Group. For investors, the key tension is visible in the numbers: operating revenue is growing, but shareholder profit remains sensitive to large investment gains and losses.

AI exposure sets the next test

SoftBank Group's OpenAI commitment now combines a USD 64.6 billion cumulative investment with a 13 percent ownership interest reported by the company. The October 1 completion removes the final tranche as an execution question, but the JPY 347.3 billion first-quarter shareholder profit shows why valuation swings across the portfolio remain material.
