— Why it moved
Why GMM Stock More Than Doubled Then Collapsed Today — June 12, 2026
A 1-for-50 reverse split plus a burst of AI headlines produced a double that lasted three minutes past the alert.

What moved GMM stock
Global Mofy AI is the company behind the Gausspeed generative-AI platform. This was day two after a 1-for-50 reverse split, stacked with a run of AI headlines — a Gausspeed milestone, an application to join the Snowflake Partner Network, and an equity stake in Moonshot AI, the company behind China's Kimi model. Thin substance, big percentages.
The mechanics
The split shrank Class A shares outstanding to roughly 1.8 million. On a float that small, premarket buying more than doubled the price before most people were awake — 10.6M shares had already changed hands by 6:57 AM.
GMM by the numbers
The alert window
Stock Pulse flagged it at 6:57 AM premarket at $5.86. The high of the entire day, $6.69, printed at 7:00 AM — three minutes later, 14.2% above the alert. Three premarket minutes is not a window anyone trades; in practice this was uncatchable.
How GMM's move ended
From 7:00 AM it faded for nine straight hours, never traded above $4.75 in the regular session, and closed at $3.35 — 43% below the alert. That $164.50 52-week high is split arithmetic, not history: the adjusted chart is down 98%, and there was an offering inside the last 60 days.
The tell: a reverse split plus a headline stack is manufactured scarcity, and the peak tends to print in the premarket minutes, not in trading hours.
