Do you mean legit players, or engine (or perhaps centaur) players too? I can't see any legit players having a win streak of very long, assuming they continued to play others near their own rating, as they'd soon run into the computers. Sometimes someone will create an account, win 50 or so games with a computer, but then subsequently get banned.
record "without losing"

How do you distinguish which players are legit and which are low-use engine players? This would be quite hard to distinguish!
But anyway, I suspect the answer will be found in someone who either plays the same person a lot, or just likes to take seeks from players several hundred points lower than them so they can win.

Yes, I am especially in awe of those players who have obtained a 3000 rating...
I decided that someone who has played a lot of games, would have large potential for a long win streak, as there are more opportunities for this to happen. With that in mind, AWARDCHESS has a best win-streak of 47 games. So this is probably the target to beat, for now.

we have to assume players not caught cheating are legit.
Oh.
I think he means for the purposes of the thread, rather than in general.

Well considering that ChessNetwork achieved a 4200 Bullet rating, I'm assuming he had a major win streak of a few hundred games, as a loss to anyone less than 3500 must cause his rating to plummet!!

Oh, by the way, although capablankamonte has won 94 games and drawn 1, amusingly the draw falls right in the middle of his games, meaning he ties with AWARDCHESS on a 47-win streak. (Albeit achieved twice!)

theres also a huge chance of timeouts, quick 1/day favored players would probably have a higher chance of streaks playing around their rating. I managed a streak of 9 but i think like 4 of them were timeouts.

the question posed record without losing on chess.com
others are on better streaks than capa'
i would bet in terms of time duration that capa' takes it though on turn based at least
>:)

Igormette easily breaks that but dunno if he´s for real, Dpruess i assume is legit he has quite an impruessive run.
I was just wondering what is the longest someone managed to play on Chess.com without losing in games total?
