The AI market is not a bubble, as major players like Microsoft (MSFT), Amazon (AMZN), Alphabet (GOOGL), and Meta Platforms (META) are funding massive AI infrastructure buildouts organically from strong cash flows, not debt. Combined CapEx for these four companies surged to $88.25 billion in Q2 2025, up 66.97% YoY, indicating sustained investment. This robust, self-funded growth in AI infrastructure by financially sound giants suggests a fundamental shift rather than speculative excess.
