What This Means for Australian Businesses and Entrepreneurs

A new US$11.1bn bond issue from Japan’s SoftBank makes clear just how much capital is being prepared to back artificial intelligence investments. The final planned investment by SoftBank, which is part of its $10 billion target, will see the Japanese company raise its total investment in OpenAI to a staggering $64.6 billion upon completion. The new funding round captures strategic alignment with SoftBank, indicating it still pours substantial cash into its OpenAI investment and the overall artificial intelligence strategy.
