Softbank's (SFTBY) massive Vision Fund, an investor in many high-growth U.S. tech firms, could soon seek to go public.

A public offering of the fund could come as soon as this fall, the Wall Street Journal reported on Friday. The $100 billion Vision Fund, which was formed in 2017, has poured eye-watering amounts of capital into fast-growing firms that include Uber Technologies, WeWork and others. It has invested nearly all of the $100 billion it started with, and it also in the process of raising a second fund. 

A Vision Fund IPO would need to overcome various barriers, including regulations designed to protect retail investors from risky venture capital investments. If the effort is successful, however, the Fund's goal is to remake itself as a smaller version of Berkshire Hathaway (BRK.B) - Get Berkshire Hathaway Inc. Class B Report  focused on technology firms, according to the Journal. Just ahead of its annual shareholder meeting this weekend, Berkshire's market cap currently stands at around $539 billion.
