SoftBank Posts Fourth Straight Profit on OpenAI Gains

SoftBank Group reported its fourth consecutive quarterly profit, buoyed by gains from its investment in OpenAI, even as it increased borrowing to expand its exposure to artificial intelligence.

The company posted a net profit of 248.6 billion yen for the October–December quarter, compared with a net loss a year earlier. A significant portion of the improvement came from the rising valuation of its OpenAI stake, which SoftBank said generated a total investment gain of nearly $20 billion by the end of December.

Founder and CEO Masayoshi Son has committed more than $30 billion to OpenAI, building an ownership stake of around 11% through Vision Fund 2. OpenAI is reportedly seeking an additional $100 billion in funding at a higher valuation, with prospective investors including Amazon and Nvidia.

To finance its AI strategy, SoftBank has relied on asset sales, bond issuance and loans backed by holdings such as chip designer Arm. It has also reduced stakes in companies including T-Mobile and expanded margin loans tied to its Arm and domestic telecom shares. The company’s loan-to-value ratio rose to 20.6% at the end of December, while its cash reserves declined.

As SoftBank deepens its investment in OpenAI, investors increasingly view the conglomerate as a proxy for the AI firm’s performance. While AI enthusiasm has lifted valuations, rising competition and escalating model development costs continue to shape market expectations.
