Altman and Musk spent the weekend accusing each other of misleading public-market investors, and the closer you look at how the AI build-out is financed, the clearer it gets why. The chip maker funds the clouds that buy its chips, the memory that just IPO'd is one cycle from a glut, and the spending still needs $3 trillion it can't yet point to

After a week that made capable models cheap and crowned memory with SK Hynix's record IPO, the mood turned to the money: Altman and Musk publicly accused each other of misleading public-market investors, and a resurfaced Beth Kindig analysis laid out the circular financing under the GPU boom — Nvidia is supplier, investor ($2B each into CoreWeave and Nebius), and demand backstop (~$6B guarantee) for the clouds that buy its chips, which borrow against depreciating GPUs to buy more. The Register warns the memory boom is "stacked for a reversal," and Sequoia's $3 trillion question hangs over it all.
