Investor risk awareness is increasing amid large bond and share offerings by major U.S. tech companies racing to dominate artificial intelligence (AI). Following SpaceX's initial public offering, its market capitalization surged to $3 trillion but has since experienced a significant decline in share value. This shift reflects growing investor skepticism about the outlook for AI-related funding efforts.

The developments highlight a strain in the previously bullish investment environment as borrowing costs rise and market confidence wavers.
