Prof G Markets — Has Nvidia Become Too Big To Fail?

Hoffman's rescue test says the government would save Nvidia but not OpenAI, because a shared supplier is systemic and a substitutable lab is not. Nvidia has guaranteed more than $108B of data center leases and holds stakes in 13 public and 229 private AI companies, which is customer finance plus credit enhancement at a scale nobody has run before. On the equity side, about 8 cents of every S&P 500 dollar is Nvidia, set against $20-25T of index-linked money. That is the balance sheet behind Jensen's rentability pitch, and index holders are the residual bearers if it fails. A stress would likely show first as a sale of a liquid stake such as Intel, and with Firmus pulling its IPO and a $150B buyback announced last week, that headline would spook markets on its own.

Bubbles Don't Pop All At Once

Hobart's AI bubble piece is the first to get the mechanism right, not just the outcome: inference floors at electricity, not zero, so the fiber collapse cannot replay. The actual risk is thesis drift. When applications cool, capital flees to picks-and-shovels infrastructure, and that infrastructure ends up funded by the same venture dollars that evaporate. Amazon grew 0.2% YoY in Q3 2001; the supposedly safe trade killed people. Oracle's counterparty-stretching debt and neocloud vendor financing suggest the 'datacenter investors are more serious this time' claim is true on average and wrong in the tail.

'Til Death Do Us Part

Drew Dickson stacks four cycles (1840s UK railroads, 1870s US railroads, 1920s RCA, 1990s internet) and the drawdown receipts are unimpeachable: RCA -98% in three years, Cisco -90%, Amazon -95%, the entire Nasdaq -78%. The fresher data point is structural, not historical: the VanEck Semiconductor ETF moves $3B a day in flows, equal to the entire daily volume of the French stock market. The actionable read is not bull-versus-bear; it is that operational AI capability and AI equity prices are about to decouple for 12-24 months, and the buy list worth writing today is the application-layer companies positioned to inherit stranded compute at 20 cents on the dollar in 2029.
