The artificial intelligence trade has fractured, with major technology companies rallying while data-centre and infrastructure stocks tumble amid growing expectations of tighter oversight of the AI buildout.
Amazon, Microsoft and Alphabet posted strong gains on Wall Street, while data-centre operators and AI infrastructure stocks suffered sharp falls.
CoreWeave and several smaller infrastructure-linked names were among the hardest hit as investors reassessed the regulatory outlook following the US midterm elections.
The market is increasingly separating companies that already own large amounts of computing infrastructure from businesses dependent on continuous expansion of new data centres.
Large cloud providers could potentially benefit if restrictions slow new development because their existing computing capacity becomes more valuable.
By contrast, highly leveraged infrastructure developers face greater risk if approval processes tighten or capital becomes more expensive.
The shift comes as investors are already scrutinising the enormous amount of capital being committed to AI.
Big Tech remains committed to expanding computing capacity, but markets are becoming more selective about which parts of the AI supply chain deserve premium valuations.
That suggests the next phase of the AI trade could be driven less by simple exposure to artificial intelligence and more by balance-sheet strength, existing infrastructure and the ability to generate cash from AI investment.
