Masayoshi Son's latest move to cash out his entire $5.8 billion Nvidia stake to go all in on AI surprised the business world on Tuesday, but maybe it should not. At this point, it’s almost more surprising when the 68-year-old Son doesn’t push his chips to the center of the table.

But SoftBank isn't bailing on AI. Instead, it's selling the world's hottest AI stock so it can buy more AI. SoftBank has already put $7.5 billion into OpenAI, and plans on investing another $22.5 billion into the company soon.

Masayoshi Son, the 68-year-old CEO of SoftBank, has a mixed track record when it comes to massive, high-stakes investments.

SoftBank Group Chief Executive Masayoshi Son's "all in" bet on OpenAI appears to be paying dividends after the ChatGPT-maker's valuation soared this year, producing a surge in quarterly profit for the Japanese technology investor.
