Ep. 037 - Who's Funding the $11 Trillion AI Buildout? (Capital Markets) | Dan Nishball, Jordan Nanos
H100 rental prices went up, on a GPU that should be sliding down its depreciation curve. That curve is what lenders underwrite. Daniel Nishball (@dnishball) kicks off our new Compute Capital Markets group by following the money through Nvidia's $497B backstops, ClusterMAX as a credit signal, and whether each token is profitable. Jordan Nanos (@JordanNanos) brings the rental data. AI debt is ab
Ep. 036 - $200 Buys $12,000 of Opus Tokens, We Bought Every Plan (AI Cloud TCO) | Max Kan, Jordan Nanos, Andrew Megalaa
Pay Anthropic $200 a month and you can pull $12,000 of Opus 5.5 tokens at API pricing. Max Kan (@maxkan) and Andrew Megalaa bought every plan, OpenAI, Meta, xAI, MiniMax, Moonshot, Z.ai, Cursor, and measured every token type to find the ceiling. The catch isn't subsidy. Anthropic still books 50 to 60% gross margins on these plans, which means the API itself is the price gouge.0:00 Cold Open1:0
