Altman's 'Silliness' Warning on AI Spending Splits Traders on Chip and Power Stocks

Sam Altman said he sees what he called 'unsustainable silliness' in current AI compute spending, a remark that put traders' attention back on the stocks most tied to that buildout. The comment lands as analysts remain split on individual names in the group. One analyst is calling for a 100% rally in Vertiv, the data-center cooling equipment maker, even as the stock has been cooling off in trading. Separately, a report argues the Federal Reserve's September decision could matter more for Micron's stock than the chipmaker's own earnings. On Nvidia, one commentary points to a single metric as the reason to keep buying the stock despite Altman's caution. The divergence is the story: the same warning from the head of the industry's biggest AI customer is being read as a reason to sell by some and ignored by others betting on specific company fundamentals. No spending pullback from OpenAI or its peers has actually been announced.
