SpaceX Drops 4% Amid Share Supply and Valuation Concerns; AST SpaceMobile Falls 6%
SpaceX (SPCX) fell 4% to $148.13 due to upcoming share unlocks, a $52M sale by COO Gwynne Shotwell, and valuation concerns. AST SpaceMobile (ASTS) dropped 6% to $60.08, and Rocket Lab (RKLB) declined 2% to $70.28, reflecting broader space sector weakness. SpaceX faces a September 24 lockup expiration with 328M shares eligible for sale, potentially increasing supply pressure.
