SoftBank Completes Roughly $40 Billion OpenAI Deal at $260 Billion Valuation

On 31 December 2025, SoftBank finalized its multi-stage investment in OpenAI, bringing its total commitment to roughly $40 billion and securing more than a 10% stake. The last payment, completed last week, was estimated at over $22 billion and came after SoftBank sold its $5.8 billion Nvidia position to free up capital. The deal values OpenAI at a $260 billion pre-money valuation and supports expansive AI infrastructure plans as tech giants, including Microsoft, Amazon, Disney, and Meta, intensify competition in artificial intelligence.
