MrBeast’s “Eat Everything In A Grocery Store, Win $1,000,000” challenge video set a channel record with roughly 68.5 million views in its first 24 hours after the October 3, 2026 premiere, fueled by 519 million subscribers, extended 20-plus-minute average view duration, and over a billion total minutes watched. Traders see the strong second-day momentum—already pushing totals near 88–90 million within 48 hours—plus widespread praise as the creator’s “best video ever” in comments and social shares as the key drivers behind the 88.5% implied probability on 100M+ views by day two. Historical patterns for MrBeast’s high-budget, long-form challenges support sustained growth in this window, with limited downside risk given the engagement metrics.
