SoftBank has pumped $2.5 billion of its cash into new investments since October, reports Reuters. The conglomerate is also considering investing another $2.5 billion of its own money. SoftBank Chief Executive Masayoshi Son said the company could spend up to two years investing its money in a bridge fund, to build a portfolio that will give investors enough confidence to participate in a second Vision Fund. SoftBank said the first Vision Fund had realized $9.5 billion in cash and mark-to-market gains as of December-end. SoftBank was targeting a $108 billion fundraise for the second Vision Fund and had committed $38 billion of its own money toward that goal.
