Why everyone from OpenAI to SpaceX is building their own chips (and turning up the heat on Nvidia)

Nvidia's dominance in AI chip market may be ending as companies like OpenAI, Google, Apple, and SpaceX build their own custom chips to reduce single-supplier risk. This shift matters as it could lead to increased competition and innovation. Companies should consider diversifying their chip suppliers to stay ahead. Building custom chips requires significant investment and expertise, but the benefits may outweigh the costs.
