SoftBank Group paid the third and final $10 billion tranche of its $30 billion follow-on investment in OpenAI on October 1 through Vision Fund 2. Its total investment in the ChatGPT maker is now $64.6 billion for a stake of about 13%. The payment was financed by a foreign-currency bond sale announced on September 24 that raised $11.1 billion, described by Reuters as the largest high-yield corporate bond issue on record.
Why it matters for listed companies
The $30 billion was SoftBank's share of the $122 billion round that valued OpenAI at $852 billion, alongside $50 billion committed by Amazon and $30 billion by Nvidia. OpenAI receives the cash and spends much of it on computing capacity, which is revenue for chip and cloud suppliers. SoftBank carries the financing risk: it drew $30 billion of a $40 billion bridge loan signed in March, repaid $25.9 billion in early September and cancelled the unused $10 billion on September 30, replacing bank debt with high-yield bonds while long-term yields are at multi-decade highs.
