The aggressive funding drive for artificial intelligence (AI) is showing signs of strain, as investors become more risk-aware due to higher borrowing costs and a less confident outlook. While big U.S. tech companies continue to seek billions for AI dominance, the bullish sentiment that previously fueled this appetite is waning. This shift in investor confidence is highlighted by events such as the slump in SpaceX's shares, which had previously seen its market capitalization balloon to $3 trillion after its initial public offering.
