After a blistering run, AI-linked stocks are taking a breather. According to The Economic Times, shares tied to the artificial intelligence boom pulled back as investors began reassessing whether their valuations had climbed too far, too fast.

The shift reflects a change in mood. In its CIO Weekly note, Coutts argues that artificial intelligence is now "a capital markets story" — meaning AI is no longer just a technology theme but a force shaping how money moves through stock markets.

At the center of the debate is a simple question: when does all the spending pay off? Big technology companies are pouring billions into building AI, and, as one report from MSN puts it, the market now wants to see the payoff "now." That report notes analysts expect Alphabet's second-quarter capital expenditures to reach $44.9 billion — a 100% increase from the same period a year earlier.

Investors are also scrutinizing the companies that supply the hardware behind AI. Yahoo Finance frames Broadcom and Marvell as a "valuation showdown" in the custom AI chip trade, comparing how richly each is priced as demand for specialized chips grows.

Taken together, the sources point to a market that is still betting heavily on AI but growing more selective. Rather than rewarding the theme broadly, investors appear to be separating companies that can show returns from those still promising them.

Why it matters: because AI has become a major driver of stock market gains, a cooling in these shares — and rising doubt about whether massive spending will earn its keep — could ripple far beyond tech, affecting retirement accounts and the broader economy.
