SoftBank explores $25bn bond offering to fund OpenAI investment

SoftBank Group is weighing a $25 billion bond issuance to help fund its major financial commitment to OpenAI, according to sources familiar with the matter. The Japanese technology and investment company has pledged to invest close to $65 billion in the artificial intelligence startup, with the funding expected to be completed by October.

Bond sales represent a traditional method for large corporations to raise capital at scale. The proposed issuance would partially underpin SoftBank's substantial investment, with the company also utilising loans and other financing mechanisms to support the full commitment.

SoftBank's investment in OpenAI reflects the intense competition among major technology and investment firms to secure stakes in leading artificial intelligence companies. The commitment represents one of the largest single investments in the AI sector and signals SoftBank's strategic focus on the technology's commercial potential.

The timing of the bond sale consideration aligns with SoftBank's broader capital raising efforts to support its portfolio of technology investments. The company has been actively restructuring its balance sheet in recent years to fund strategic initiatives across artificial intelligence, cloud computing, and other emerging technologies.
