Breakfast News: A One-Line Fix Could Shake Up AI

Amazon (AMZN) jumped 5% after releasing TorchNeuron, an open-source tool that lets PyTorch code run on AWS Trainium chips with minimal changes. The move directly challenges Nvidia (NVDA) and its market dominance in AI hardware.

Interpretation: if developers can port existing PyTorch workloads with a near one-line change, the switching cost that has favored NVDA shrinks. The 5% AMZN reaction suggests the market is pricing that possibility, though adoption data would be needed to confirm it.

Elsewhere, Karooooo (KARO) fell 8% despite strong subscriber growth. Earnings came in below expectations and guidance was left unchanged, a combination that overrode the growth headline.

Earnings are coming for two high-profile names. Netflix (NFLX) is expected to be judged on ad revenue growth, while SpaceX (SPCX) will be scrutinized for AI spending efficiency.

MercadoLibre (MELI) continues expanding across Latin America, with heavy investments in shipping and payments.
