SoftBank Group Corp. on Monday reported a record loss at its Vision Fund unit as the value of public holdings like Coupang Inc. and Didi Global Inc. plunged.

The unit’s loss in the three months through Sept. 30 was ¥825.1 billion ($7.3 billion), exceeding the ¥788.6 billion loss the business posted amid pandemic-driven writedowns. Overall, the Tokyo-based company had a net loss of ¥397.9 billion in the period.

Masayoshi Son’s Vision Fund has been a volatile contributor of profit and loss since its creation in 2017. The first downturn started in 2019 with Uber Technology Inc.’s disappointing public debut and the implosion of WeWork, followed by the impact of the coronavirus.
