SoftBank's $100bn Vision Fund is deducting 15 per cent of its 500 global staff after it reported $18bn (£14bn, 15.8bn) of losses in the past financial year.
The cuts at SoftBank Investment Advisers (SBIA) are set to begin this week and hit a wide range of functions within the unit, according to two sources close to the matter.
The firings mark the first big round of cuts at SBIA since it was created in late 2016 to manage the London-headquartered Vision Fund.
