PALO ALTO, U.S./TOKYO — OpenAI’s latest $40 billion funding round positions Japan’s SoftBank Group as a leading partner for the U.S.-based ChatGPT developer looking to build artificial intelligence infrastructure to compete with such new players as DeepSeek.

The investment announced Tuesday Japan time — six times the size of the ChatGPT developer’s last round in October and an all-time high for an unlisted startup — doubled its valuation to $300 billion. SoftBank is contributing three-quarters of the total.
