Softbank also owns 65% of the GreenBox venture, which launched with $100 million in investment by the two companies. They say it's a $500 billion market, and an example of the kind of change AI can bring to the economy at large. But not as many investors know about Softbank's "other" big AI investment, Wilmington, Mass.-based software and robotics maker Symbotic , which Walmart has taken a big stake in itself. Symbotic teamed up with Softbank to build GreenBox in order to preserve its own capital, Cohen told analysts. The GreenBox market for smaller companies shapes up as another $500 billion of possible demand, Gartner's Klappich said.
