SoftBank chief Son explores debt-heavy financing for $500 billion AI push

A few weeks ago, SoftBank Group Corp. founder Masayoshi Son stood alongside US President Donald Trump to unveil the Stargate Project, an artificial intelligence venture with OpenAI that could cost $500 billion or more. Now Son is figuring out how to pay for it.

The Japanese billionaire is looking at a technique called project financing that is sometimes linked with oil and gas projects, according to people familiar with the matter.
