Swedish YouTuber, comedian and gamer–commentator PewDiePie and Indian record label T-Series are in a neck-and-neck race to be the first YouTube channel to reach a 100 million subscriber count.

At the time of writing, PewDiePie has over 93M subscribers, compared to the 92.7M for T-Series. T-Series has temporarily overtaken PewDiePie on numerous occasions in 2019.

Will Pewdiepie be the first YouTube channel to have 100 million subscribers on YouTube?

This question resolves positive if Pewdiepie is reaches the 100M mark before T-Series. For the purpose of this question, we shall refer to subscriber counts given on Socialblade, i.e. those here: PewDiePie, T-Series. This question will close retroactively 7 days before the 100M mark has been reached by either of the two. This resolves ambiguous if a channel on this list that is not Pewdiepie or T-Series is the first to achieve 100M subscribers.
