Misra, who structured and ran the record-breaking $100bn Vision Fund, said he would remain involved with SoftBank but that his new venture would pursue investment strategies beyond start-ups.
The shake-up marks the latest sign of unrest inside SoftBank, which has been roiled by plunging valuations for technology companies as well as an exodus of senior leadership over the past several months.
The new fund would be backed by Abu Dhabi state funds Mubadala and ADQ, as well as Royal Group, the conglomerate chaired by Sheikh Tahnoon bin Zayed al Nahyan, the United Arab Emirates’ national security adviser, said Misra.
