They aren't afraid of risk and they've been around long enough that they appear to be at least an averagely competent investment firm which just takes way more risk than most would consider reasonable. Softbank was also founded in pretty much the perfect time in history for a firm like themselves to succeed, a highly speculative low interest rate environment. Their hits have more than made up for their misses.
