On September 8, Howmet Aerospace Inc. declined 6.31% in regular trading, trading at approximately $244.24 per share, with turnover of $130 million. The stock had already fallen 3.11% in pre-market trading before accelerating losses during the session.

The sell-off stems from continued market fallout over Elon Musk's announcement that SpaceX will begin manufacturing blades and vanes for natural gas turbines, claiming the move could accelerate gas turbine deployment timelines by up to 18 months. This directly challenges Howmet's dominant position as the holder of over 50% global market share in industrial gas turbine blades. According to a Morgan Stanley report, SpaceX's planned foundry would produce single-crystal nickel-based superalloy components for both its Raptor rocket engine turbopumps and gas turbines.

However, Wall Street analysts have pushed back on the severity of the reaction. Citi maintained a Buy rating with a $329 target price, arguing SpaceX's entry reflects extreme demand strength and turbine manufacturing capacity scarcity rather than competitive deterioration. Bernstein questioned whether SpaceX can achieve large-scale production within the proposed 18-month timeframe and noted Howmet's existing supply agreements with major turbine manufacturers extend through 2030.
