[TOKYO] SoftBank Group said on Friday (Mar 27) it has secured a US$40 billion bridge loan to bolster investments in ChatGPT-maker OpenAI and for general corporate purposes, marking another significant step in its artificial intelligence strategy.

The Japanese investment conglomerate, led by founder Masayoshi Son, continues to strengthen ties with OpenAI as global tech firms race to gain an edge in the increasingly competitive generative AI space.

The Japanese investor has previously agreed to invest US$30 billion in OpenAI through its Vision Fund 2. The bridge loan is unsecured, the company said.

The loan, which matures in March 2027, was arranged with lenders including JPMorgan Chase, Goldman Sachs, Mizuho Bank, Sumitomo Mitsui Banking and MUFG Bank.

OpenAI, backed by Microsoft, has emerged as a leading player following the widespread adoption of ChatGPT, prompting a surge in investment across the sector.

The loan underscores Son’s increasingly aggressive bet on AI following years when SoftBank swung between outsized gains and heavy Vision Fund losses.
