Felix 'PewDiePie' Kjellberg could be about to lose his status as the most subscribed YouTube channel.
However, a challenger is brushing alarmingly close to that record. T-Series, an Indian music label, is hot on the heels of Kjellberg with a cool 59 million subscribers.
Statistics tracker Social Blade predicts that T-Series will overtake PewDiePie in the next couple of months, given the rate of growth for the two channels.
The data shows that T-Series is gaining an average of 142,203 subscribers per day, whereas PewDiePie is only bringing in 29,980. If the trend continues, T-Series will overtake PewDiePie in October this year.
The comparison is a little off given that T-Series is a network and PewDiePie is a gaming channel run by one man, but it's been a long time since anyone came close to knocking Pewds off the top spot.
It was Kjellberg himself that pointed out the rivalry in a recent video. It's not a serious call to arms, just Kjellberg waving a sword about and telling T-Series to "fight him irl".
Whether Social Blade's projections are accurate - we'll have to wait and see. Perhaps Kjellberg can rally enough support to put a little more distance between himself and T-Series before autumn rolls around.
