A single tweet from Elon Musk topples the leading turbine blade manufacturer! SpaceX (SPCX.US) announces self-manufacture of gas turbine blades, causing Howmet (HWM.US) to experience its biggest drop in 16 months.

Golden Ten Data APP reports that aerospace precision components giant Howmet Aerospace (HWM.US) closed down 7.51% on Monday, plunging as much as 9% during the session and hitting a two-month low, marking its largest single-day decline since April 2025. The trigger for the sell-off came from a statement by Musk on social platform X: SpaceX will independently cast industrial gas turbine blades and vanes, directly targeting the core bottleneck currently limiting gas turbine production capacity.
