SoftBank Raises $11 Billion in Bonds to Bankroll OpenAI Bet

SoftBank has launched an $11 billion bond sale to fund its investment in OpenAI, according to a Reuters report.

The offering marks one of the largest debt raisings by the Japanese technology conglomerate in recent memory and signals how central the ChatGPT maker has become to Masayoshi Son's investment strategy. SoftBank is leaning on bond investors rather than its own balance sheet to finance the stake.

The $11 billion figure underscores the scale of SoftBank's financial commitment to OpenAI. The company has made artificial intelligence the organizing principle of its portfolio under Son, who has repeatedly described AI as the defining technology of the era.

For bond buyers, the deal offers exposure to SoftBank's credit story at a moment when the group is concentrating risk in a single, closely watched private company. OpenAI remains privately held, and its valuation has climbed sharply as investor appetite for large language models and AI infrastructure has intensified.

The bond launch also fits a broader pattern. Major technology and telecommunications groups worldwide are raising debt to fund AI commitments, from data center construction to equity stakes in frontier model developers. SoftBank's move shows that financing for the AI buildout now flows through corporate debt markets as well as equity.

Reuters did not report the tenor, pricing or investor demand details of the offering in its initial account. Those terms will determine the cost of the bet for SoftBank and the return demanded by creditors for exposure to an AI-concentrated credit.

The sale's completion would give SoftBank fresh firepower for its OpenAI commitment without diluting shareholders. How bond markets absorb the $11 billion tranche, and at what yield, will offer an early read on creditor appetite for financing the AI investment cycle.
