There is no wildfire coming. The model providers have narrowed down to 4: OpenAI, Anthropic, Google and xAI. The chip manufacturers are Nvidia, Google (TPUs) and AMD is trying to break in as well. Microsoft is position very well as a middleman. All these guys are giants already. Just Nvidia, Microsoft and Google together have a market cap above ten trillion. OpenAI, Anthropic, AMD and xAI probably add one trillion more.
Sure, there might be hundreds or thousands of small startups in the AI game, and some are probably as viable as the fabled Pets.com. But even if they all crash and burn, it's going to be a rounding error compared to the 7 companies I mentioned above. The AI will be alive and kicking, and nobody will even notice.
