Dow Jones| Nasdaq | US Stock Market Today | Live: SpaceX IPO is said to draw more orders than shares available; Nasdaq slips over 1.5%

Global equity markets are being driven by an unprecedented surge in AI-related investment, with companies like SpaceX, Google, OpenAI, and chipmakers fuelling record capital inflows. Analysts say AI spending is now a major driver of US growth, masking broader weakness in consumer demand and private investment.

However, concerns are rising that valuations in AI and semiconductor stocks may be overstretched, with earnings not fully justifying investor optimism. Heavy market concentration in a few tech giants across the US, Asia, and Europe is adding systemic risk, as indices become increasingly dependent on a narrow group of companies.

While chipmakers and AI infrastructure firms continue to benefit from massive demand, some recent earnings reactions suggest expectations may be running ahead of fundamentals. Analysts warn that if profitability fails to match hype or if interest rates stay elevated due to inflation pressures, markets could face a sharp correction despite the ongoing AI investment cycle.
