MrBeast’s main YouTube channel sits at approximately 515 million subscribers as of early September 2026, following his June milestone of 500 million. Daily gains have averaged 100,000–200,000 subscribers in recent weeks, supported by near-daily long-form videos, high engagement rates, and consistent algorithmic promotion. With roughly 28 days until September 30, this pace positions the channel to clear incremental thresholds such as 516 million or 517 million, though momentum can fluctuate with upload cadence, video performance, and platform-wide attention shifts. Traders weigh his proven ability to sustain outsized growth at scale against the natural slowdown observed at higher subscriber counts.
