Clear Signal

Special episode on the AI investment boom. Research current as of October 31, 2026. Is there an AI bubble? Nvidia's growth outlook, big-tech spending, CoreWeave and Oracle credit, Anthropic's filed numbers, the strongest skeptic case, and a 3, 6, 12 and 18 month set of dated tests. Analysis, not investment advice. Figures are labeled by source and date; my own arithmetic and judgment are marked as such.

NOT VERIFIED: Anthropic's public filing leaves its compute commitment total and Q3 revenue blank. I found no OpenAI filing. Anthropic's offering timing comes from press reports, not the filing. Alphabet and Amazon capex guides are CNBC-reported.
