It isn’t clear how Loops will work as Threads doesn’t use traditional hashtags, instead allowing users to tag their posts with a single topic or phrase, such as “Tech Threads” or “Sports Threads.” These can be pretty generalized though,

As first reported by TechCrunch, Threads is testing a community groups feature that’s similar to Subreddits and X Communities. Chris Messina, a Threads early adopter, discovered this after scanning the latest app update’s code.

Meta's take on a Twitter/X rival, Instagram Threads, may be inching further into its competitor's territory with the development of a communities feature

Meta's Threads is reportedly developing a new community feature called 'Loops', a new community-based feature similar to the X app or subreddits.

The feature is known as Loop, and one developer who spotted the reference said that it might be similar to the Communities feature on X, or subreddits … Alessandro Paluzzi first found the feature. Chris Messina appears to have independently spotted it.
