When the music stops, someone’s left holding the bag — or as Margin Call’s John Tuld put it, “I don’t hear a thing. Just silence.” After billions vanished during a 4x surge in “pump and dump” schemes, NasdaqNDAQ

is cranking up the volume on new rules, hoping to bring some order (and sanity) back to small-cap stocks.

• The tech-focused exchange introduced an “accelerated process” to delist small, noncompliant stocks — while raising the minimum public float to $15M and mandating a $25M IPO floor size.
• Thanks to their ~70% share of related enforcement actions, the rules largely target Chinese companies— but they also follow recent hype-fueled fundraises from American nuclear, quantum, and robotics firms.

Pump the brakes: Nasdaq isn’t just gunning for penny stocks because crypto treasury plays are feeling the heat, too. New rules require shareholder approval before companies can issue stock just to add more bitcoin to their balance sheets, a move that could seriously slow the growth of the 1M bitcoin ($111B) already held by firms chasing digital gold. In a world drunk on speculation, Nasdaq decided that not everyone can handle another round.
