The Financial Post reports in its Saturday, Aug. 30, edition that Meta is developing "Prometheus" and "Hyperion," Elon Musk's XAI has "Colossus," and OpenAI is working on "Stargate," each a $100-billion (U.S.) project aimed at creating powerful supercomputers and advancing artificial intelligence. A Financial Times dispatch to the Post report that these initiatives, however, are just a small part of the massive investments needed for the data centres that will drive the AI era, representing one of the largest capital movements in modern history. Blackstone data centre manager Rob Horn says: "The amount of capital required is absolutely immense. The scale of the opportunity is exhausting the capital of market, and is requiring an all-of-the-above approach, with private capital playing a very large role." Alphabet, Amazon, Microsoft and Meta will spend more than $400-billion on data centres in 2026 -- on top of more than $350-billion (U.S.) this year. However, as the money floods in, concerns are being raised about overcapacity, long-term profitability and energy demands. One banker says, "We are in that period where the capital markets are crazy enough to throw money at almost anything."
