I'm not sure how many folks these days would consider him an "oracle". He clearly did fabulously well with some early Internet investments, but he also was famous for folly after folly of overpriced investments in the 2010s (the Softbank "Vision Funds").
I'd be curious if there is a simple accounting list of Softbank's major investments ranked from biggest winners to biggest losers. I guess it pretty much highlights the dynamics of the VC business model - you only need a few giant winners to offset the boatload of losers. In Softbank's case, I'm guessing their biggest winners are Yahoo Japan (which was the dominate site in Japan for a long time, and long after the US Yahoo fell into irrelevance) and Alibaba, which saw their early $20 million investment balloon into billions.
But did Softbank have any winners from their 2010s spending spree (along the time where they shoveled good money after bad into WeWork)?
