Oracle founder Larry Ellison will join Apple, Qualcomm and Foxconn in backing SoftBank’s record-setting technology fund, allowing the Japanese telecoms group to hit its $100bn goal weeks ahead of schedule. Abu Dhabi’s sovereign wealth fund is also in talks to invest in SoftBank’s Vision Fund, according to people briefed about the negotiations. These people added that the fund will remain open to additional investment until the end of January as demand from both large companies and sovereign funds remained strong.
