Delays, cancellations and power-grid constraints are prompting investors to reassess the AI infrastructure boom, with South Korean memory-chip makers alert to a possible slowdown in future demand for HBM and server DRAM.
The growing doubts around artificial intelligence investment are no longer confined to Silicon Valley boardrooms. In the United States, a series of delays and cancellations affecting data centre projects is prompting a fresh reassessment of the build-out that has underpinned the AI boom, while South Korea’s memory-chip makers are watching for any sign that demand for high-bandwidth memory and server DRAM could soften over the medium to long term.
According to recent reporting cited by the Financial Times, at least 47 large US data centre schemes have been delayed, withdrawn or suspended this year, and some estimates now suggest that projects worth as much as $260bn may ultimately be scrapped. Reuters also reported that Microsoft has pulled out of an agreement tied to a Nscale data centre in Britain after power connection problems pushed the expected supply date into the 2030s. The episode underlines a wider constraint on the AI industry: the pace of power-grid expansion is increasingly dictating whether projects can move forward at all.
The pressure is not only financial. Communities in several parts of the US are opposing new facilities over concerns about electricity use, water consumption and environmental damage. That local resistance is adding to the operational and regulatory hurdles already facing developers. At the same time, the Wall Street Journal has questioned whether the profits now being generated by AI companies can be sustained at current levels, a concern that has revived talk of an AI bubble after months in which heavy capital spending had briefly muted the scepticism.
For chipmakers, the immediate picture remains firm, but the longer horizon is less certain. Demand for memory components used in AI servers has so far held up, and there are no clear signs of an abrupt fall-off. Even so, if large-scale data centre construction slows, the implications would eventually reach suppliers of HBM, server DRAM and related components. The industry’s concern is therefore not a present shock, but a possible delay in the next phase of demand growth if the infrastructure boom proves harder to sustain than investors had expected.
