There is an interesting fact that there is no FIDE-rating below 1,000, if I am not mistaken, but also no FIDE-rating above 2,900 (Hikaru Nakamura's OTB-Blitz-ratings in the highest at the moment), so why we find a rating even below 800 and far above 2,900 here. Interesting is now that the rating on chess.com is normally higher than your FIDE-rating, so how come there are much lower ratings and much higher ratings compared to FIDE-rating? Is it the number of games top players can play (much more than OTB), a "wrong" FIDE-threshold, a different rating system or what is the reason of this phenomenon?
Those are excellent questions that I am certain that many other players have posed at some point during their competition on Chess.com
While an official answer to your question could probably be better provided by one of the more experienced Moderators on Chess.com, here is a short video describing the correlation or relationship between Chess.com blitz ratings and USCF & FIDE ratings.

Roughly speaking, I believe that a 2150 Chess.com blitz rating correlates to about a 2350 USCF rating and 2400 FIDE based on metrics analysis of my own ratings & the ratings of players whom I know personally on Chess.com. It is in some ways close to the results generated by the analyses provided in the video, but I believe that there will invariably be some variation based on the actual skill level of individual players. That being said, a 2150 blitz rated player may have the actual skill of a 2200-2350 USCF or fall within a range of 2100-2200 FIDE. Meanwhile, a similar more highly skilled 2150 blitz player who has the same rating but lower Glicko RD may actually have a much higher rating range of 2350 USCF and 2400 FIDE. The ratings are dependent upon the individual more than any formulaic assessment model.
There's actually a thread on here that has a link to a site where it shows the relationship between FIDE/USCF and chess.com blitz rating. For anyone who is interested, that thread is https://www.chess.com/article/view/chesscom-rating-comparisons.
Thank you for the link to the article.
No problem.
I believe that there is a direct correlation between your rating on Chess.com and the overall rating systems internationally through USCF & FIDE.
There are players rated within the 2100 to 2200 level who are titled players in various countries of origin. FM NM IM GM WFM WIM WNM all of which are tremendous accomplishments in and of itself.
By reviewing the overall curve of ratings on Chess.com it is clear that once you reach a certain level of chess proficiency, you cross over into the rating levels highlighted in this thread topic.
I disagree
Online ratings are "overrated" (lol) in my opinion. Too many variables are involved beyond every player's control.
There's internet connection strengths, ways of manipulating ratings and rampant "unfair" play... to mention a few.
Just because some has an online rating of "x", doesn't mean they have a corresponding OTB rating of "y".
The anonymous accounts of titled players alone corrupt any online stats you're using.
I've seen online bullet players >2000 play like an 1200 rated player at times. It's like comparing apples to oranges.
True colors start shining through once someone disagrees with this fake.
