MrBeast hits 400M YouTube subscribers before September 2026 [BB]

MrBeast has already cleared the 400 million subscriber threshold on his main YouTube channel, so this market would resolve as a yes if the event is defined strictly as hitting 400M before September 2026. Available reporting says he first surpassed 400M on June 1, 2025, and later received a custom 400M play button from YouTube. That makes the target date in this market comfortably satisfied well before the cutoff. The main remaining nuance is how the market is worded and whether it uses any specific verification source or timestamp requirement, but for a normal subscriber-count-based resolution, the outcome appears settled. Recent milestone tracking also shows he was already in the high-400M range by spring 2026, indicating continued growth well beyond the 400M mark.

• —MrBeast reportedly first surpassed 400 million subscribers on June 1, 2025.
• —A July 2025 report says YouTube recognized the milestone with a custom 400M subscriber play button.
• —By late April and early May 2026, third-party milestone trackers show MrBeast already in the 480M+ subscriber range.
• —Because 400M was reached in 2025, the market condition 'before September 2026' is already satisfied.
• —This is a main-channel YouTube creator market, so the relevant identifier is his primary MrBeast channel milestone data.
