There is actually a real bull case for xAI (that I don't endorse), e.g. from people who think that chips & computer is the main determiner of model quality. xAI may plausibly soon have the biggest training apparatus of anyone.

I think talent is more important than compute, as I wrote in my Jan 2026 predictions that Anthropic would end up on top this year: https://futuresearch.ai/blog/forecasting-top-ai-lab-2026/
