The Softbank Vision Fund was unveiled less than a year ago, backed by Saudi Arabia and Japan's SoftBank. By May it had raised $93 billion, out of a planned $100 billion, to spend on technology businesses of the future. The Vision Fund expects to raise the final $7 billion in the next month or so but it's wasting no time in putting the committed cash to work. It's already invested in 10 firms, leading funding rounds worth at least $7.7 billion.
