The Financial Post reports in its Tuesday, June 10, edition that shares of companies providing infrastructure for artificial intelligence are rising after a previous decline, boosted by increased spending from Big Tech. A Bloomberg dispatch to the Post reports that Goldman Sachs's two indexes -- one for AI data centres and electrical equipment, the other for data centre power suppliers -- are up 52 per cent and 39 per cent from April lows. Major tech companies like Amazon, Alphabet, Microsoft and Meta are significantly investing in AI, easing concerns about ongoing funding for essential AI infrastructure. Bloomberg Intelligence's Robert Schiffman reports a 16-per-cent increase in capital expenditure forecasts to support AI demand since the start of the year. Roundhill Financial's Dave Mazza says, "Earnings season reminded investors that generative-AI doesn't run on buzzwords -- it runs on concrete, copper and gigawatts." A strong start in 2025 faltered as concerns over competition from China's Deepseek start-up and global trade uncertainty made investors question the justification of massive investments. The sell-off was worsened by tech giants like Microsoft pulling back from data centre projects.
