A handful of executives at SoftBank Group Corp. are weighing the idea of an initial public offering for its Vision Fund, the $100 billion behemoth that has invested in technology companies ranging from Uber Technologies Inc. to WeWork Cos.

The idea is in an early stage, said a person familiar with the situation who asked not to be identified because it was private. If pursued, an IPO would give investors in the fund a way to cash out part or all of their stakes. The fund might consider a direct listing rather than a traditional IPO, the person said.

A listing of any sort would be unusual for a venture firm, but the Vision Fund has operated outside of traditional venture parameters since its debut in 2016. It dwarfs other funds in size and invests more broadly than most venture funds, including in mature companies like chipmaker Nvidia Corp.
