**MrBeast’s latest long-form upload, “Eat Everything In A Grocery Store, Win $1,000,000,” posted around October 4, 2026, has driven the 150M+ week-one bracket to 66% implied probability.** The roughly 60-minute “mini movie” format posted a channel-record 68.5 million views in its first 24 hours—well ahead of recent comparables—bolstered by 519 million subscribers, aggressive pre-release X promotion, and strong early engagement (over 10,000 comments calling it the channel’s best). Recent high-budget Saturday releases such as “Escape 100 Cops” and “Last To Leave Mansion” have routinely cleared 110–120 million views in seven days, and YouTube’s updated view-counting method (first-frame plays) has further lifted early totals. Traders view the combination of proven audience habits, positive critical reception on social platforms, and MrBeast’s consistent production scale as the key factors locking in the leading outcome, with the video’s strong first-day trajectory providing the primary catalyst.
