SoftBank Group posted a profit in the October–December 2025 quarter. Investment gains tied to OpenAI drove the swing. The company also raised fresh funding to support larger AI commitments.
SoftBank reported net income attributable to owners of the parent of 248.587 billion yen for the three months ended December 31, 2025. A year earlier, it reported a loss of 369.165 billion yen for the same period.
SoftBank linked a large part of its recent investment gains to OpenAI. In its financial report, the group said Vision Fund 2 recorded investment gains tied to OpenAI, which supported overall returns.
The company also detailed the scale of its OpenAI funding. SoftBank said it completed an additional $22.5 billion investment on December 26, 2025. It said the funding fulfilled a commitment made in March 2025 and ran through SoftBank Vision Fund 2.
SoftBank said its aggregate ownership interest in OpenAI now stands at approximately 11%. The company said other co-investors also participated, bringing the final aggregate commitment to $41.0 billion.
Masayoshi Son, SoftBank’s Chairman and CEO, said the group aligns with OpenAI’s goal of broad benefits from advanced AI. OpenAI CEO Sam Altman said SoftBank’s scale helps OpenAI move faster.
SoftBank increased its use of secured financing during the same period. The company said it amended the terms of a margin loan using Arm shares, lifting the facility to $20.0 billion from $13.5 billion. It then drew $11.5 billion of remaining capacity in December 2025.
SoftBank also increased borrowing tied to its domestic telecom holding. The group said it raised borrowings under a margin loan using SoftBank Corp. shares by 400.0 billion yen, taking the total from 800.0 billion yen to 1,200.0 billion yen in December 2025.
The company described other funding actions tied to its investment program. It cited bridge loans used to fund OpenAI follow-on investments and noted repayments made during the period.
SoftBank reported a 4.4067 trillion yen balance of cash and cash equivalents at the end of the quarter. It said the figure rose from the prior fiscal year-end level after the combined impact of operating, investing, and financing cash flows.
The group also pointed to monetization and portfolio activity that supported liquidity. It disclosed proceeds from the partial sale of T-Mobile shares between June and December 2025 and confirmed a complete sale of NVIDIA shares in October 2025.
In its investing cash flow notes, SoftBank said Vision Funds made significant investment payments during the nine months. It highlighted that these payments primarily reflected follow-on investments in OpenAI through Vision Fund 2.
