— 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 it Day two after a 1-for-50 reverse split, stacked with a run of AI headlines — a milestone for its Gausspeed generative-AI platform, 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.
## Numbers - Cap: single-digit millions / ~1.8M Class A shares post-split - Day volume: 35.7M — many times the float - Prev close: $2.88 → alert was already +103% above it - 52w range: $2.50–$164.50 (split-adjusted)
## Where it ended up Stock Pulse flagged it at 6:57 AM premarket, $5.86. Three minutes later it printed $6.69, and that was the high of the entire day. From there it faded for nine straight hours — never above $4.75 in the regular session, closing $3.35, 43% below the alert.
## Reality check - Three minutes to peak. Effectively uncatchable, and everything after was fade. - That $164.50 52-week high is split arithmetic, not history — the adjusted chart is down 98%. Recent offering inside 60 days too. - This already happened. It's a breakdown of why it ran, not a reason to buy it.
