SoftBank Group Corp. is in discussions with investment banks regarding a potential bond offering valued between $10 billion and $20 billion. The funds would be used to refinance a $40 billion bridge loan secured earlier this year for its investment in OpenAI, a US-based artificial intelligence company. The offering could be denominated in dollars and euros, with the possibility of issuance as early as September, according to sources familiar with the matter.

The proposed bond sale is part of SoftBank's broader strategy to manage its debt obligations, which have grown significantly in recent years. Earlier this year, companies globally have borrowed more than $410 billion for similar facilities and other purposes. SoftBank has previously issued bonds, including a $3.6 billion sale in April, which included a 10-year dollar tranche with a record 8.5% coupon.

The potential bond offering could mark a significant shift in SoftBank's debt issuance strategy. Unlike most of its international offerings, the company is exploring a 144A format for the first time in more than a decade. This format would allow the notes to be sold to institutional investors in the US, potentially broadening the investor base and improving liquidity.

The move could have wide-ranging implications for SoftBank's financial structure and its ability to manage its growing debt burden. It may also influence investor confidence in the company's long-term strategy and its ability to navigate the challenges of funding high-profile investments in emerging technologies. The outcome of these discussions could shape SoftBank's financial trajectory in the coming years.

As the talks continue, the details of the bond offering remain subject to change. The potential issuance is still in the early stages, and no final decisions have been made. The outcome of these discussions could have significant implications for SoftBank's financial strategy and its broader investment in OpenAI.
