The move follows the completion of SoftBank's third OpenAI investment tranche, a transaction disclosed by SoftBank Group on October 1, 2026.
OpenAI funding reaches USD 64.6 billion
The final tranche amounted to USD 10.0 billion, taking SoftBank Group's previously announced follow-on investment program to USD 30.0 billion. The company said its cumulative investment in OpenAI had reached USD 64.6 billion, representing an ownership interest of approximately 13 percent as of October 1, 2026.
The transaction was funded through senior notes issued in September. SoftBank Group also canceled USD 10.0 billion of undrawn bridge-facility capacity effective September 30, 2026, and said all borrowings under that facility had been repaid, according to the same SoftBank Group release.
What does November 10 mean?
The next hard test is the company's Q2 FY2026 report for the six-month period ended September 30, 2026. SoftBank Group scheduled the financial report for November 10, 2026 at 3:30 p.m. JST, followed by an earnings briefing at 4:30 p.m. JST. That date puts the accounting impact of the OpenAI financing and the September debt actions at the center of the next results discussion.

On October 1, 2026, it executed the USD 10.0 billion OpenAI tranche. On October 2, 2026, it published the November 10 results briefing schedule.
