George Noble, managing partner at Noble Capital Advisors, warns that the current AI investment surge could represent the largest capital misallocation in history. He estimates the scale of this potential bubble to be 17 times larger than the dot-com era, during which telecom firms spent $65 billion on unused infrastructure.
Big Tech infrastructure spending grew from $155 billion in 2022 to a projected $755 billion in 2026, with forecasts exceeding $1 trillion by 2027. Research from Wharton indicates that productivity gains would need to triple for these investments to break even, a target that has not been met.
Noble highlights concerns regarding circular vendor financing and accounting practices that may inflate the perceived productivity of AI investments. Notably, NVIDIA reported a 770% growth in receivables, raising questions about whether demand is organic or supported by aggressive financing arrangements.
Analysts at Jefferies suggest that affordable Chinese open-source AI models could threaten the US market by offering comparable results at lower costs. Additionally, in mid-September 2026, an Anthropic researcher resigned after publicly warning about potential existential risks associated with AI technologies.
