MrBeast’s main YouTube channel continues adding roughly 80,000–150,000 subscribers daily as of mid-September 2026, driven by consistent weekly long-form challenges, Feastables integrations, and strong view velocity on recent uploads. After hitting 500 million in June, the channel has sustained momentum despite its massive base, with 30-day gains around four million and engagement metrics holding steady in the top tier of entertainment creators. Traders are watching upload cadence and any surprise mega-videos through late September, as historical patterns show accelerated growth around high-profile releases that can shift implied probabilities for the September 30 threshold.
