Unity Software was rumored to be considering going public earlier in the year, and the company has now officially filed for an initial public offering with the Securities and Exchange Commission (SEC). The document was filed on August 24th, and you can view it in full here for more details.
The IPO itself won't take place immediately, and it's difficult to predict how long it will take for the process to be completed. We haven't been able to find any official information, although one estimate claims that initial public offerings generally take between six and nine months.
Some of that includes time spent preparing for the registration statement, but on the other hand delays could be longer during the pandemic. So this is all speculation until we get more information, but hopefully things will be wrapped up by the end of the year.
If you're not familiar with Unity, it's an engine that's used to develop game on basically all major gaming platforms. Among others, Unity supports Windows, Mac, iOS, Android, Playstation 4, Xbox One, and Nintendo Switch along with VR devices like Oculus Rift, Playstation VR, Gear VR, and Steam VR.
A few of Unity's recent games include Ori and the Will of the Wisps, Pokemon Mystery Dungeon: Rescue Team DX, and Untitled Goost Game. They're behind a wide range of other popular titles, and Wikipedia has an entire page set aside to list games that use a version of the Unity engine.
It's hard to determine how Unity will be valued after going public, but it's currently one of (if not the) most popular engines. Make sure to keep an eye out for future updates on this story if you're interested in investing in Unity.
